Short notice first: I have no idea what I'm talking about, no knowledge, I just did some research and hope what I found is right.

Although the cam, especially the 3MP-version, is not the best I've seen, I'd like to have all features that are supported by the hardware. The inspiration for this thread came from the Samsung galaxy i7500. On the official Samsung-ROM, the cam was able to do pictures. After they wrote a new driver for the cam (Samsung dind't give any sourcecode for it) they got it working on 2.2, and took the chance to enable everything the hardware can do.
This includes:
  - Auto focus mode (Touch to Focus, Autofocus,...)
  - Exposure compensation
  - Scene mode
  - Effects
  - Iso
  - Meter mode
  - Saturation
  - Sharpness
  - White balance
  - Wide Dynamic range
  - Image stabilization control
  - Face detection
  - Zoom

I hope that most of this is possible with the Blade too.
The original thread for the i7500 can be found here:

After searching the web and modaco, I found these informations:
http://android.modac...l-optimization/
The sensor of the 5MP-cam is named "ov5642".

The sensor seems to be the sensor of the iPhone 4.
The other parts of the cam seem to be way better.

Documentation of the firmware for ov5642. There are some limitations mentioned for autofocus:

OmniVision had built-in the embedded auto focus control in firmware of OV5642. This
document is only for the firmware of this solution. Currently, the auto focus firmware supports
following auto focus camera modules:
1. OV5642 + VCM + AD5820
2. OV5642 + VCM + AD5822
3. OV5642 + VCM + AD5827
4. OV5642 + VCM + DW9710

Does anybody know which auto focus module is built into the blade? Since the blade can do autofocus I think it is one of those, and everything else in the documentation should be possible.

Some information about Android and OV5642, but doesn't seem to be usefull.

So, for the 5MP-cam you can find that it supports AF on different areas in chapter 6 of the firmware guide. This should be enough for Touch-To-Focus.

MT9T112 or MT9T111 is the sensor of the 3MP-cam.

Flexible support for external auto focus, optical

Some random information about aosp and MT9T112

Information for MT9T111: (Warning, 6.5MB!)
http://www.aptina.co...ument.do?id=683
Autofocus is mentioned on page 91.



Now, my question:
Can anyone who has knowledge about those things look into this and tell me what is possible? Don't want to hold you away from fixing the RIL, but maybe there is someone who is great in writing drivers and bad in fixing RIL
By the way, is the camera driver of the Blade open source?

Edit: Face Detection:
I don't think the hardware supports it, but shouldn't it be possible to do this in software and autofocus on the region?

I've found this: http://www.linuxhq.c...video/mt9t112.c - I assume it's a source code of a driver for MT9T111 from the 2.6.37 linux kernel... I hope that this can be of any use

this sensor outputs high-quality images at high speeds and can be programmed through a simple two-wire serial interface.

I had noticed that our phones were said to have an I2C bus in there somewhere ...

I didn't want to write a new firmware for the sensor

Do you want to take a look on Camera 360, buddy? It probably does most of it. I'm nobody being professional here. Just passing by, hope it helps!
