Performance difference between Omnivision, ST, and Sharp camera modules mic quality. - One (M7) Q&A, Help & Troubleshooting

So I might be getting another replacement One, and I'm wondering if the new Omnivision modules that they've started using are any good.. I was reading the specs on the website (model: OV4688) and it seems that it doesn't offer OIS, it says Electronic Image Stabilization on their website. Also, I read somewhere that they're very poor in low light.. Anyone got proof to back these up? Any pictures to show the differences between these? Also, any difference in the mic audio quality between the old and new batches?

So I wrote about this in one of the purple camera fix threads. First I'll see I haven't noticed any puple/pink hues in any pics in lowlight. It seems to be performing well in that area. I also don't have a pink spot in the middle.
Occasionally in the outer edges I might notice some green tint in low light - particularly in rooms that have a shade of green in them already. It doesn't however grow and get worse. Its just the outer fringes. When I switch the camera from wide to regular crop it pretty much goes away. If not, its easily fixed with a quick touchup by adjusting the saturation with a custom effect in the gallery or just using aviary and the one click color fix. Also you can avoid it all together by adjusting saturation down a notch in the camera settings before taking a pic.
However.....what I have noticed is that in indoor lighting, even good lighting, the video recording frames per second maxes out at like 19-20. This is kind of a bummer. I mean I've turned on a all the lights in a really well lit room and could not achieve what I could in fps compared to the old sensor. I've tried different camera apps and they all max out at 19-20 in these light conditions, which tells me that its most likely set in the kernel. I wonder if this sensor has not been optimized fully by HTC yet. I think they've worked with three different sensors so far: ST electronics, Sharp, and Omnivision. Perhaps its hard to accomidate them all in the kernel - but I'm just speculating. there.
My compromise is to shoot indoor video at the 60fps mode, because that caps out indoors at 40fps.
I've fully tested video outdoors and even this morning indoors when there was no artificial light source and it recorded at a full 30 fps.
If what I think is true - that its not fully optimized at the kernel level it could be something HTC can push out in an update. Perhaps its hard for them to try to support 3 different sensors and find a balance...But this is just speculation on my part. Now I've lived in the same house and conditions for the past year and the old sensor had an edge up on fps than the Omni. I looked at some old videos shot indoors last night and fps was hovering around 29-30. So far this is my only gripe.
A note about the Sensor:
Early on Brian at AnandTech when he reviewed the One talked a bit about the Sensor HTC used when building the first Ones, and he also compared the ST sensor to the Omnivision sensor, because that Omni made its debut at the 2013 CES. Here is his review:
http://www.anandtech.com/show/6747/htc-one-review/5
I find it interesting that 2 companies made identical sensors, ST and Omnivision according to Brian.
Overall I'm happy I sent my device in and had the sensor replaced, because in the end, no amount of quick photo tools or photoshop would help the purple tint issue.
Hope this helps.

Camera Tint? Blue?

Anyone else notice their stock camera taking more blueish photos in various lighting?
I primarily use Camera 360, and that seems to compensate for the blue stock camera tint?
But, I must say the stock camera app is quite nice.
I am not seeing that on my camera, but I have only snapped a couple of pics in bright light and have not checked on the computer.
Are you sure your camera is not set to "Blue Tint"? On the bottom of the camera is a bar you can slide to open, the second item has options for different camera modes.
yes, I did notice this. Seems to depend on the lighting.
I've noticed a blue tint with the flash on in lower light indoor pictures. I think the camera will take some adjustments to work well. Outside it took pictures just fine. I had to have the flash off the for almost all indoor pictures.
It's definitely blue-ish/whited out with the flash and I use Vignette.
Hopefully a software update will help correct this a little bit.

Noticed this right away as well, mainly in fluorescent light. This is definitely correctable via software and from what I understand is a known issue on a very long list of known issues for this device.
Another thing I thought of - when a friend of mine got the OG Droid back in the day when it came out, I was very impressed with the camera and camcorder.
With the DX2 and D3 I'm a bit disappointed, it's almost like they took a step back. I feel like the OG Droid is better at video and photos than my Xoom as well.
Does anyone else feel like their cameras have gotten a little worse over time? I remember the Razr had some of the sharpest 1.3 MP photos (as well as Samsung and of course Nokia has always kicked ass in the photo department).
Wow, 1.3 MP... that's like the standard for a lot of front facing cameras that aren't VGA. Oh, and the 2 MP FF camera on the Xoom is grainy as **** in artificial lighting.
Other than the camera and battery issues, I LOOOOVEEE this D3. I miss a keyboard too much. And I feel like this screen is less grainy than the DX2 (but from what I gather the screen resolution would look denser on a smaller screen, right, since it's not spread out as much with the same pixels?).

Holiday Camera inside and out

Well I decided to make a post explaining how blessed you are to have this phone's camera. Since I'm a professional photographer, this stuff is important to me
Camera Specs:
Megapixels: 8
Sensor: CMOS (pretty small i don't know the sizes exactly)
ISO range: 100-800 (naturally, software can increase to at least 1200)
Aperture: 2.2​
Explanation of these specs:
CMOS Sensor, common in almost all cameras today, rarely you'll find a CCD, they do produce better image quality but use much more power.
8 Megapixels, this isn't really important unless you are blowing your picture up. the human eye actually cannot tell a difference past 4
ISO range, this is actually important, the lower your ISO is the less sensitive the sensor will be to light, making a need for more light for a properly exposed picture, but giving a better image with less noise and sharper details. the higher the iso the more sensitive the sensor is to light making it easier to take pictures indoors or in darker situations, with the trade off of noise.
Aperture, this is the opening of the lens that lets in light. the bigger this is the smaller the number (i don't get it either, deals with some math) but the bigger, the less light is needed for a properly exposed picture meaning less ISO needed. also it adds that blurred background​
If something doesn't make sense and needs further explaining don't hesitate to ask!
Also check out the amazing Bananacake's HQ Camera mod giving uncompressed images and video!
Is had a 4s dude compare to me . Apparently his photos were a lol better. I also had a dusty screen protecter and maybe also the lenses
His orange was more orange lol
Sent from my HTC PH39100 using XDA
his phone has a 2.4 aperture, but better glass in his lens though, the manufacturer Carl Zeis is one that makes 10,000 dollar lenses lol. we can also focus ALOT closer for awesome closeups
but our pictures come out better they have comparisons online to.
Let me say it right now...as a photographer myself. It's more the photographer than it is the camera.
Sort of like I've always believed its the violinist, not the violin
Sent from my HTC-X710a using XDA
I believe in that as well except I'm like super nerdy with camera specs.
My thing is, it doesn't hurt to have it

HTC One Camera Quality

Hi,
I am considering buying HTC One but there is just one thing that makes me rethink my decision and that is the 4MP Camera. It's a stunning device but I am a bit skeptical considering the low megapixel count of 4 in HTC One. People who have already got the phone and also people who have researched on the imaging quality of "The One", please shed some light on the camera bit.
I know it is good for low light conditions but are the daylight photos good enough if not the best that GS4/ iPhone 5/ HTC One have to offer.
Thanks a lot!

Daylight images are good, but maybe not as "good" as the GS4 purely cos of less details from the lower MP sensor. HTC is probably one update away to perfecting their metering and auto-exposure, but it is still very good and don't forget really really fast
Megapixels are not a measure of image quality. Never has been, never will be. Higher MP just means bigger prints.
The size of the sensor determines image quality. The One camera takes better photos than my 8MP Nexus 4.

That's cos the Nexus 4 had a pretty meh sensor I'd say stock S4 camera app is about as good as modified HoX camera For low light, nothing really beats the One though

Yep, there's been an arms race, so to speak, with manufacturers trying to compete with one another over buzz words, "megapixels" being one of these. The Anandtech HTC One review by Brian Klug covers in excruciating detail the tradeoffs HTC made with the camera hardware vs. marketability

To be fair and honest, I find the shutter speed to take long sometimes in natural and incandescent lighting indoors. I could be sitting at the dinner table and be underneath our ceiling fixture and the picture would be a little out of focus or take too long when the lighting is good. I'm assuming this can be fixed with software tweaks. It's almost as if the sensor takes in too much light sometimes, as I find myself having to turn on the flash manually in some indoor shots.
The positive side, the PHONE takes great pictures in outdoor lighting and even indoor with the right lighting or flash. The colors come out more natural and detailed than my wife's S3. Compared to my old Inspire, the One is 100x better.

I've just been reading a thread on the S4 forum about the lag on the S4 camera. It can take superb landscape pictures in bright light but it struggles with moving images.
The One on the other hand is extremely fast which translates into, for the most part, images with no blurring. And of course low light pictures are far superior which is what everyone raves about.
It really depends what you want from a camera. I, like you, was worried that 4mp would be too much of a downgrade. I then started to think how I actually used my camera. I predominantly take pictures of my family and friends, kids playing in the park etc. I rarely ever view the pictures I've taken on a device that has a better resolution than 1080p and don't crop images often.
A 4mp camera is far higher resolution than 1080p.
As soon as I started snapping my kids, often indoors at dinner times with only fluorescent lighting, I was happy I plumped for the One. It really is astounding how fast it is, and the pictures look lovely on the phones 1080p display.
I would much rather have lower MP. pictures I can use than constantly having to delete blurry higher MP pictures.
Best thing to do? Check out both forums. They are a far more accurate representation of performance than reviews.

Does cropping render the quality very low?
Something to add, is that if you take low light video (night clubs, bars, dimly lit rooms etc) the video framerate will fluctuate between 17 and 30fps, causing it to look choppy. That is the only thing I hate about the One at the moment. Choppy video in low light. The galaxy s4 (and my old s3) do not have this issue

It's just different companies prioritizing different things. The One tries to get in enough light regardless of what it has to do, and that means fluctuating frame rates in low light video. The S3, S4 and Lumia do different things in where they force 30FPS, but in return you get much less light in, making the video darker. But the phone is still plenty new, and we can all hope that HTC would give us an option for what we want, shutter speed priority mode please

Speaking of the software, if they're gonna include Zoe and all that, I wish they'd provide a Highlight studio of sorts where you can choose the transitions/music/frames etc on the phone.

Is it really 4 Mega pixels??
I thought it was 4 Ultra Pixels??
Surely that different?
"Ultra Pixel" is a marketing name for this sensor, it's still a 4MP device with bigger pixels to get more light and reach the f2.0 limit. Not more only bigger.

It's 4 Megapixel in resolution, but the sensor has more than 4Megapixels. They extra pixels are used solely to capture light, and that's why it has very good low light capabilities
Here's the technical explanation of this ST Microelectronics CMOS Sensor:
The Camera
The HTC One bucks the trend. Based on the 1/3″ form factor of a camera module and today’s state-of-the-art 1.1 µm pixels, all the latest competitive phones sport 13 Mp resolution. HTC has gone with a larger 2.0 µm pixel (confirmed) and a 4 MP sensor. They are pitching the low light sensitivity as a key feature. The device is a back-illuminated sensor fabricated by STMicroelectronics with die marks 58698A. This is the first BI sensor we have seen from ST.The camera uses the IDG-2021 gyroscope by Invensense for motion stabilization. It is a dual-axis gyro with high resolution ADCs designed specifically for optical image stabilization.The secondary sensor is a 2 Mp, 1.4 µm sensor by OmniVision with die marks OV2A9BA. It is a nice secondary sensor that we have seen before in other phones.

The moving video is fantastic with the optical gyro.always smooth videos.
And takes great night shots with longer exposure cause it's easy to get a steady photo.
Why does mine say pn071?

Personally I love the 4MP cam in the One. I came from a long line of iPhones and although they're not perfect, I realized that the most I was going to be doing was hold these images for viewing on my computer, sharing at times. Between the 13MP GS4 and the One I thought it was an easy decision to get the One. I just don't see a need for 13MP size picture files laying around in my computer taking up space.
Now I'm just a normal consumer from a photog perspective. I have a graphic arts background, but I rarely perform treatments or heavy manipulation on my own photos. Take some shots with the One demo at your local store. You'll be amazed at the clarity, especially when zoomed in.
So, i used this device for over a month and so far the camera works great to me, i compared it to other phones i got in touch like iPhone 4s, Note 2 and the S3, video recording is just great on HTC One, it just works better in my opinion, great clarity, good autofocus.
As for photos, it's great, all the photos on 100% zoom look bad, but the HTC One photos look modest at 100% zoom so i don't really think camera is a deal-breaker, it's a great camera the thing is HTC opted for a more revolutionary camera and so far i think they've done a pretty good job.

Missing OIS Feature?

Anyone notice that optical image stabilization is missing in the specifications? I just did a quick search and found several sources saying its digital stabilization. A little bummed about that. Thoughts anyone? :crying:
From the videos, its pretty stable with digital stabilization compared to other smartphones no?

Yeah, can't wait for a couple full blown reviews. If anything, hopefully they will bundle the qx10 for preorders in the US too. I hear the qx10 has the optical stabilization. I'm just worried about the low light blurriness. I had the 1020 and it was fantastic.
Smartphone makers try to close the image quality gap between their phones and actual camera.
However, to be honest, I do not rely to much to phone camera.
Their lens can't and sensors can't compare to actual camera even point and shot one, not saying SLR cameras.
Anyway, a phone without a camera is also something should be in history.
It doesn't have optical image stabilization. That's why the night shots aren't so good. OIS allows for slower shutter speed and more exposure. The digital image stabilization is only used for video. All phones have this already. The Lumia 920/925, Lumia 1020, Note 3, HTC One, and LG G2 have OIS, but Sony chickened out and wanted a FLAT camera with no bump because it ruins their sense of aesthetic. They could probably make it even thinner and flatter if they removed the camera and battery completely. How about removing all the internals? A beautiful sliver thin paperweight that looks nice as long as you don't touch it and smudge it up with your filthy plebeian fingers. I'm sure there are many buyers among the Sony loyalists for this sort of product.

Dude, what is your problem? It's only a phone with camera that can rival with the best currently available when it comes to pure picture quality. It bests S4 in low light shots and rivals 1020, in daylight photos you can clearly see more details compared to S4 (which by many is considered to have the best camera on android). What is true is that Sony still needs to improve their algorithm but even as it is now it can produce exceptional photos even in full 20mpix resolution.

There'a a difference between disappointment and senseless bashing and that is what I was criticizing.
I agree that it is a shame that they weren't able to include OIS or sensor shift but I think that it could have been currently impossible with such a big sensor and bigger lens than other manufacturers. It is a shame but it's not something that automatically makes it worse than G2 or note 3/S4, on the contrary I still think that it'll end up doing better pictures than both of them.
Sony SteadyShot
It's not all down hill guys, the Z1 has Sony's SteadyShot technology in it, it just appears to only work in video mode which imo is best place, I suppose there will be more clarification once it's out......http://www.sonymobile.com/global-en/products/phones/xperia-z1/features/#camera

You're just trolling. I've been checking on the photo samples from the Z1 for the past couple days cause I'm considering getting one. I've been waiting for HTC to announce the One Max, but the lack of doing so at the IFA completely made me give up on them and push me toward getting a Z1 instead. At first I noticed the photos had a lot of noise from the Z1 photo samples, but it seems like the noise was taken cared of via software update. The lack of OIS doesn't exactly affect the quality of the photos so far from what I see. The photo samples from the Z1 look more natural than 1020's which had a yellow tint to it. The photos were so defined when comparing the HTC One under low light condition and HTC One is only a bit behind on 1020 under low light condition.
Really, i think at this point we all just need to get our hands on one and give it a shot. The sample photos floating around on the internet certainly haven't been flattering but that could be due to any number of variables. Any word on US release yet?
Exposure is basically the AMOUNT OF LIGHT (controlled by the aperture) that is captured over a SPECIFIC AMOUNT OF TIME (controlled by the shutter speed).
A HIGH aperture number (fstop) = LESS light being recorded on your digital sensor while a LOW aperture number = MORE light being recorded on your digital sensor. apertures are called fstops
Shutter speed: it is the amount of time your shutter stays open when you click the button
The longer your shutter stays open the more motion it will have time to record. The shorter the time your shutter remains open, the more motion it will freeze. But at low light you need more exposure
ISO rating along with the shutter speed and aperture setting are the three elements that determine the final exposure of the photographic image.
The ISO rating, which ranges in value from 25 to 6400 (or beyond), indicates the specific light sensitivity. The lower the number, the less sensitive to light the film stock or image sensor is. Conversely, a higher number indicates a higher sensitivity to light, thereby allowing that film or image sensor to work better in low light conditions.
the lower ISO rating also meant that the photosensitive grains of salt on the film acetate were very fine, thus producing a smoother, cleaner image. A higher ISO had larger, jagged grains of salt, thus producing “rougher” or grainier images.
Lower ISO ratings produce color-accurate, smooth and aesthetically appealing images… and this requires ideal lighting conditions. However, there are some subjects that you want to photograph in low light conditions. Or, you may want to stop fast-moving objects. In both situations, you need higher ISOs to capture those images with an acceptable exposure.with the higher ISOs, you can use faster shutter speeds to eliminate motion blur and/or camera shake. In the event that you want to use motion blur creatively, then decreasing the ISO is simple, and you can then decrease the shutter speed to achieve the desired motion blur and still have smooth, noise-less images.
The size of the digital camera’s image sensor dictates what ISO setting provides the least amount of digital noise. One must understand that image sensor size is not the same thing as pixel count. Image sensor size is the actual physical dimensions of the sensor, for most of the history of digital photography the image sensor has been smaller than a 35mm film frame. On point and shoot cameras, the sensor was quite small, and on most DSLR cameras, the image sensor has been the size of APC film (23x15mm). Smaller image sensors produce much more digital noise at higher ISOs (like 800) mainly because the high pixel count means that more pixels are being packed into a smaller area, thus producing more grain at all but the lowest ISO.
Whenever you shoot in low light or use a long lens, or if you simply aren't holding a camera steady, you risk introducing camera shake into your images. This manifests itself as a blurring of details, and unlike other image quality issues it's not something that can be fixed in post-processing.
The three main image stabilisation systems on offer:
Manufacturers have different names for lens-based stabilisation, but they all largely work in the same way.
ISO based
All but the cheapest compacts offer image stabilisation, and the easiest solution from the manufacturer's point of view is one based on sensitivity. This adds nothing to the manufacturing of a camera as it's simply the ISO which needs to be adjusted, easily handled by the camera's firmware.
As this is the most basic form of image stabilisation, and as other types are preferable, manufacturers often call it 'digital' image stabilisation in press releases and throughout specification lists.
With this type of image stabilisation, the camera looks at the focal length and shutter speed being used, and decides whether the two will create a sharp enough image. If it deems them to be inadequate the camera's sensitivity will be raised, which in turn increases the shutter speed, but the resulting signal will need to be amplified to a greater extent.
So, a camera could choose to raise an image that would be otherwise captured at 1/20sec to 1/80sec, but it would need to raise the sensitivity twofold. So, from ISO 100 this would rise to ISO 400, from ISO 200 to ISO 800 and so on.
The image is still captured sharply as a more appropriate shutter speed has been used, but this process gives rise to noise which is typical with images captured at higher sensitivities. For this reason other systems are preferable in more expensive cameras and lenses. In many compacts, this method is often complemented by sensor-based stabilisation.
Sensor based
Sensor-based stabilisation also uses information such as focal length and shutter speed on which to base its calculations, but instead of adjusting the sensitivity the camera physically moves the sensor.
The sensor will typically be mounted on a platform, which will move to compensate for any movement when the camera senses it is necessary.
Minolta first introduced the feature in its DiMAGE A1 camera back in 2003, and, after merging with Konica, incorporated it into the 7D DSLR.
Sony continued the feature when it took over Konica Minolta's imaging business, and was soon joined by Pentax, Olympus and others. All three companies continue to use the system today, and it has since been adopted by other manufacturers for their own hybrid systems and compacts.
In the case of DSLRs and hybrids, this type of image stabilisation brings the significant advantage of allowing lenses to be made smaller, lighter and cheaper (as they do not need to incorporate any form of image stabilisation themselves), and is effective with virtually any mounted lens. This is particularly handy in the case of older lenses which predate image stabilisation technology, although it may be necessary to first input the focal length of the lens into the camera, depending on the lens, camera and the nature of communication between the two.
Lens based
Lens-based image stabilisation came just before digital cameras were made accessible, but the two have more or less evolved over a similar space of time.
Today, the technology is found in a range of optics manufactured by Canon and Nikon (particularly those targeted towards the professional), as well throughout the ranges from independent lens manufacturers Sigma and Tamron. Panasonic also uses the system in its lenses designed for the Micro Four Thirds system, as well as those found in its Lumix range of compacts.
Lens-based stabilisation systems typically work by shifting a lens group towards the rear of the lens on a plane perpendicular to the optical axis.
This is done with the help of two gyro sensors inside the lens, one for yaw and one for pitch. These notice the angle and speed of any movement, and this information is fed to a microprocessor which computes the necessary adjustments needed to be made by the lens group. By doing so, the light's angle of refraction is changed so that it hits the sensor in the right place.
Manufacturers of these systems claim that this type of stabilisation is the most effective as it can be tailored specifically to the objective in which it us used. And, as stabilisation takes place in the lens, the photographer is able to view the effect through the viewfinder.
Typically this activates once the shutter release has been half-depressed, although it is possible on different camera/lens combinations to set when the stabilisation begins, such as only at the moment of capture, for example. This has the additional benefit of conserving power, as, left on all the time, lens-based image stabilisation systems can eat up battery power fairly quickly.
One recent development in this area is Canon's Hybrid IS system, which offers two types of correction.
The first is via an angular velocity sensor which notices rotational shake, which is found in existing image-stabilised lenses.
Canon 100mmThe second - and what makes the Hybrid IS system different - is a separate sensor for noticing camera shift (linear) movements, such as when a camera moves up, down, left or right while remaining parallel to the subject. Canon claims that by incorporating both sensors camera shake is better corrected.
Now i guess everyone got importance of OIS feature..
And i tried the camera of xperia Z1.. the picture was blurry at full zoom. but noise was absent..I feel low noise is more important than full zoom blur...because the photo is excellent for normal usage
wow, thank you that was a great read.

White balance issue on 1x(RYYB) and 5x lens?

I'm on .140 and find Primary lens (RYYB) has white balance issue especially with red-orange object
test it with 1x(RYYB) compare to 0.9x(RGGB) or Super Macro(RGGB) mode.
also 5x come with really blue tint.
Is Huawei know this? How one device has different color profile for every single lens that far away from "natural" color

1x then close-up to super macro

This is the only thing that make me think about a Galaxy S10+ instead of P30 Pro, the S10+ (in my own opinion) is better in every single aspect but the camera, and if there is now way to get it working properly, it doesn't worth my money. Hope it get fixed soon.
Perhaps it's fluctuations in lighting causing throwing the white balance measuring off, some types of led and fluorescent lights have slow frequency 50/60Hz updates where the white balance varies quickly.

Definitely strange behaviour with white lights.
Taking a photo at night, the white lights are blown with red outlines.
Look at the temple examples. From 1x and 5x lenses
Ok. Now I think this is serious problem after saw color checker compare in this article... Huawei should fix it asap ?

Aye no prob, color correction is much better on the .153. Pretty sure Huawei knows and they're applying fixes probably in stages. The browns tend to become a little over saturated still but irl images are much better than day 1
