Hello all,

I used a usb camera http://www.si-cube.com/Products/cctvequipment/22/ on the gumsitx, but I'm not satisfied by the quality. The usb camera shows anything that's dark blue as purple, normal blue becomes very intense blue and outside everything becomes gray.

Another thing I don't like is that I cannot control white balance and some other settings, while the image sensor is capable of doing so (so i guess the board doesn't translate the I2C to USB correctly?).

My questions:
Is there a way to fix this?
Can you suggest another (small, light) camera?

Regards,

Bart
