Weird idea, replacing the camera CCD

Hey,
My digital camera (Canon A75) got broken. It's too old and there's no point in fixing it. But I had a weird idea, do you think it's possible to implement Canon's CCD chip into the Universal? I believe this part of the camera is still intact. I have absolutely no experience with this type of hardware so I figured I'd ask before attempting anything.
Is there some kind of standard to this stuff? I'm assuming that besides hardware issues there's also the lense that has to fit exactly the same. I'm not expecting to put Canon's zoom lense or anything, because that would be useless on the universal. I just want a higher quality image.
Maybe someone can point me to the right direction or spec pages. I'm not sure where to look for this.
It would be cool to have a 5MP camera on the universal
Thanks

Who knows if backlight can work as flashlight?

Hi all,
The light at the back that works like, when you flip the phone upside down while having a caller, the phone mutes, and the light flashes so you are aware you still have someone on the phone. (which i think is a useless issue of having a light for, for just that reason only)
I like my flashlight on the first Touch Pro. Specially with some good software where it can also work as a Torch!
Does anyone know if the light on the back of the TPII can work as a camera-flashlight or as a torch?
Extra comments:
TPII blows, it doesn't have much better hardware then TP. Just a bit better software upgrade. To bad.
Look at samsung, LG etc. all already with 8MP camera's! Here comes HTC's latest: with a 3.2MP, and NO flash!
I hope the leaked out details for HTC 2009 line-up will come true.
One (SuperStar) supposedly will have nVidia chipset , I hope so, finally to watch DivX/XviD videos!!!
And one (Thoth) will have a chipset of a 1000Mhz processor!
Hopefully HTC will combine the 2 forces together!
A phone with lots of internal mem, fast processor, fast HD video chipset (incl. tv-out), good quality speakers and mics, a 8MP camera! WITH FLASHLIGHT for f*ck sake! at least 1800Mah battery! Qwerty Keyboard Slider. Side-Keys for easy mobile gaming. And maybe even the latest MicroVision PicoP micro-projector!
Come-on HTC, you want to make profit again? Make the best available phone out today!
Greetings
P.

i assume that if someone makes and app (similar to the iphones) that makes the screen completely white and maxes out the backlight then yes! but it wont work as well as an LED flash like with the TP

There is no LED for the camera that could be used as a flashlight.
An indicator LED is nowhere near powerful enough to act as a flashlight usually, so I don't think you'll be in luck.
Regarding your comments saying how the TP2 'blows', I'd say it's a big step forward from the TP2 - a proper replacement for the Kaiser (big WVGA tilting screen!). Not perfect, but it is probably the best hardware Qwerty phone on the market (or will be!).

I always hear ppl complaining about the camera...
Cameras in Phones don't have as much room, as such they're limited in size, making the Mpixels harder to achieve, making the threshold for the oh so fun whitenoise lower.
I'd be happier with a 3.2 that gives me perfect pics, as opposed to a 8.0 that gives me noise.
Also if I KNOW I'm going to take pictures... I have a camera for that. The camera on the phone is just for "geez lemme get a pic to remember that" for anything more a phonecam just won't cut it without all the "gimmicks" a real camera has (like a real focus)
A flash? on a Phone targetted at businessmen... well yeah why?

A flashlight? Seriously?
The white led's that lay under the Call and End buttons are well enough to come with a warning label on their own.
People are seriously concerned whether a hi-tech piece of mobile communication and data access device can double as a f'n flashlight? wow.

There is an app called flashlite in dev and hack section
This can be helpfull your question

HTC's site lists the following for camera in their specs for the TP:
CameraMain camera: 3.2 megapixel color camera with auto focus and flash light
Second camera: VGA CMOS color camera
Here is the listing for the TP2:
CameraMain camera: 3.2 megapixel color camera with auto focus
Second camera: VGA CMOS color camera
I think that pretty much sums it up for you. I like the flashlight on my TP, but this is definitely not a deal breaker for me. I think the screen size is a significant upgrade over the TP, otherwise the internal hardware is more or less the same. I could care less about 8MP. My 3.2MP Olympus camera is still the best one I have owned. Why do you need more than that especially in a phone?

Camera Noise :(

I've seen threads saying you don't buy a phone for its camera, but the noise from the Touch Pro 2's camera is unbelievable! Attached are 3 pictures, one from the Touch Pro 2, one from the Touch HD, and one from the Touch Diamond 2.
All were shot at default settings, at 3m pixels, in well lit indoor light, then selectively cropped and magnified by 200% to highlight the noise levels. The Pro 2 even shows an enormous amount of noise outside in bright light!?

try to set the ISO as low as possible.. 100 for example

Does anyone know if the problem with the camera is hardware or just a poorly made camera driver? as I have had a 3.2 mp phone camera before and it seemed to take better pics.... Strange dont you think?

well, without going too much into the physics of camera sensors, some rule of thumbs:
- the smaller the CCD sensor (for same resolution), the smaller the pixels, the greater the noise!
- you cannot build a good camera without good optics / lenses. usually, mobile phone cams have very poor lens quality - don't expect anything
- you can correct noisy pictures to some extent by post-processing (can be done by the cam HW itself or by SW) but you'll loose details.
consequences:
- if you want to shoot nice photos, buy a digital camera
- if you still want to shoot photos with your mobile, make sure light conditions are bright!

I've tried that, and whilst outdoor pictures in good light are ok, indoor ones at 100 ISO come out blurry because a higher ISO speed is needed.

I understand all of this, but I'm merely showing the difference between 3 "similar" HTC devices, where two are "acceptable" and one seems to exhibit an enormous amount of noise?

as you also wrote, "similar" in quotemarks...
- we don't know which camera HW is mounted in the devices (there can be cams from different OEM vendors even in the very same type of device depending on production series)
- we don't know what post-processing software (with which settings) is used...
I'm not surprised at all by the miserable quality
/edit: sorrily, I cannot see the so-called EXIF info in the pics (the forum engine cuts this out), from which we could see the parameters with which the images were taken (eg. which ISO sensitivity was applied, etc.)

Fake rear second camera?

Daisy should have second rear 5MPx camera but I dont think that is even used, it feels like just a hole. Doesnt help for bokeh, in low ligh, for zooming. If I covered it image was the same. Anyone knows when this camera take any effect?

same problem, bad front camera experience

next time please read post before you write some unrelated text

I think so too

It is definitely not fake.
You can test by going to dialer and typing *#*#64663#*#*
In that test mode you can test each camera lens ( finger over lens) and that will verify both cams do in fact "work"
Not saying the software actually uses both, but the cams are in fact real

Im not so sure in my case:laugh::laugh::laugh:
edit:same for dual back camera

With the stock camera app, it does work correctly. Perhaps you should contact warranty...

The portrait mode that focus only on what is close must be a proof that the second camera works, right?

If you cover the second camera in potrait mode in stock cam app, you will see that it is not working properly anymore

the 2nd camera only there to enhance DOF information
not to actually take a picture.
front camera is also able to fake the DOF but its slower and not so accurate when compared to the rear camera

This works for me! Thanks. I don't know why others doubt their smartphones

i also use this model and i think that secondary dual cam is just for show off it does not do any thing. its a mimic only for branding purpose.

So many people have no idea what they bought.
The first sensor is a 12MPx Sony sensor (bottom one) that captures standard photos, in focus.
The second sensor is a 5MPx Samsung sensor (top one) that analyzes the whole frame and returns RAW depth data for the camera app to process, to bring a better blur effect for the portrait mode.
This is a bonus to the classic software portrait mode, it helps. It's not useless, and it's not for show off.
The fact that it doesn't work as good in dark environment is because the Samsung sensor is cheap and can't give enough data in darkness.
Now, let's see when both cameras work at the same time (not applicable on this device):
- when the secondary sensor is black and white, this helps the pictures get more dynamic range
- when the secondary sensor is the same as the other sensor, this is used for 3D imaging (chech HTC 3D)
Now when 2 modules work independently and can be switched via software:
- when the main lens are normal and the other lens are wide lens
- when the main lens are normal and the other lens are zoom lens
Now, our device doesn't fit in either of the above categories and the best way to use the Portrait mode is to use a ToF sensor, but baring in mind the price of our device the ToF sensor was replaced with a standard, low quality camera sensor from Samsung.

Enabling 32 MP mode

So ,I was skeptical of posting this ,but maybe it can be a spark for new development
At first ,I believed that perhaps the camera sensor in the A70 is just 8 MP and some marketing jargon made it appear 32 MP
Idk if this app is true or not but it's actually identifying the sensor as a proper GD1 Samsung sensor with resolution of 32 MP
Yet ,the software is only reading 8 MP from this sensor ,which may mean that there is probably an issue with software rather than hardware
I am no expert ,but I thought this might help us to perhaps unlock our device's full potential

the came api responds to the apps (gcam included) that the camera has only 8mpx
is the api
there are devices where peolple with root and twrp can change this
but it is not working on A70

It's a 32mp sensor, we've always known this. 32mp IS available but only using Samsung's own api, which is only available (so far) in Samsung's camera app. You can verify that yourself by taking a photo in 3:4H mode. Look at the details and the res will be 6528x4896 - 31.9 million pixels. So it's real and it's there. I also don't understand why people are chasing this mode when it's been shown that it's no better than the usual 12mp mode. Would what be nice though is having access to 12mp through the Google camera api, this would allow 12mp in gcam for example, instead.of the 8mp we are currently stuck with. Not.that the photos are bad in gcam but I believe theres a bit more detail to be resolved if we had the full 12mp.

Yes, pics taken with the GCam are good. The pic and resolution quality is acceptable and a level above the Samsung app even in 3:4H mode. But the quality is still a level beneath my Iphone7, in my testing.
Still hoping to see a high MP Gcam or significant software updates to the Samsung camera app.

Thanks to everyone for the reply
It's just annoying as hell to have low megapixel count ,because I usually love cropping into my photos and it really limits me , specifically because of a lack of telephoto lens as I love architecture photography
Another worthy note : I tested over 10 apps that check the hardware info of the phone
None of them could manage to identify the ultrawide cam nor the depth sensor ,all of them only identify the front and back camera...which probably mean there is sort of hope that maybe the Camera2API provided by Samsung is not really fully unlocked and it strict the readings of the entire camera module
If a developer could clarify why the ultrawide isn't identified I would be super happy

Maybe its an advantage of not owning a flagship phone before coz I have nothing to campare the cam of A70, but for me the 32mp mode is really good specially when using outside with good natural light, the zoom image is very impressive imo. Yes the gcam takes better images overall but I really love using the 32mp mode from the stock camera
