Re: [M560x-driver-support] recent updates to po1030 sensor

[David P. <dcp...@ma...>]

My po1030 sensor based camera is still not behaving correctly.

In Skype the image is pink, and in livecam bayer mode, greenish
(brightest colour is bfffc0)

It also appears that it is not correctly adjusting for different ambient
light conditions. The image is totally washed out if the room is too
bright. Is this supposed to happen?

I now have time to fiddle with the driver myself.

How can I best go about learning how to get these things working?

cheers
