Okay, are there some other cameras avaiable with 160x120 pixels or
output in rgb? I only have an ARM Cortex-A8 with 500MHz to process the
image data and converting between different pixelformats take a long
time. So it would be fine if a resolution of 160x120 pixels is supported
or the output is in rgb.
ov538-ov7690 solution
static const struct v4l2_pix_format vga_mode[] = {
{ 176, 144, V4L2_PIX_FMT_YUYV, V4L2_FIELD_NONE,
.bytesperline = 176 * 2,
.sizeimage = 176 * 144 * 2,
.colorspace = V4L2_COLORSPACE_SRGB,
.priv = size176_144 },
I think that it has the 160x120 resolution too, but I don't write the code for that.
The sensor arrive at 60 fps in QVGA mode

I'm searching a v4l supported webcam with a framerate higher than
30fps. I found the Playstation Eye and it seems to have a framerate
of up to 120fps @320x240 pixels.
Does this camera support a resolution of 160x120 pixels? How are the
images transfered over usb (jpeg, rgb, yuv)?
Hi Joern,
The resolutions are only 640x480 and 320x240. The images are transfered
in YUYV (16 bits YUV 4:2:2).
Regards.
