Hi everybody,
I just wanted to ask if someone of you recently had a look at the camera
driver for the ov3640 sensor included in the omap zoom 1 platform. As I'm a
total noob in writing drivers I'm searching for someone to help me to get this
device to work the right way because currently it's really a mess.
Unfortunately our future work with the omap zoom heavily relies on having
camera images in reasonable resolutions and reasonable quality, so for us there
is no way around fixing at least some of these points:
As far as I have seen there are several issues. The main problem is that it is
only possible to use a very restricted number of image formats. One can use
Bayer images in 1024x768 up to 2048x1536 pixels, and using the Bayer format is
the only way to get RGB images actually. The much more appreciated YUYV and
YVYU formats seem to be broken somehow, so nobody is known to me who was able
to decode such an image into a reasonable color image yet. Lastly, a problem is
that there is no way to control the exposure of the sensor, such that the
images are all heavily over-exposed and there is no way known to me to change
any setting to use auto-exposure (the feature is reported to be not available
by v4l2).
I'd be happy if someone could help me in fixing some of these problems.
Regards
Clemens
