[M560x-driver-support] Clevo D870P m5603c notebook video upside down (SENSOR_7648_V14) and dark colours - help please

[David C. <da...@pa...>]

Hi,

Can I please have a little advice as to what I might change to make the 
colour work better in the situation below?

I have the m5603c driver somewhat working on my Clevo D870P notebook 
with some hacks to the source to flip the video horizontally and vertically.

I have hacked away the upside-downness of the image by editing 
m5603c_core.c, inserting cam->vflip = 1 and cam->hflip = 1 just prior to 
calling ov7648_start(cam) in  function set_callbacks_start_sensors.

My remaining problem is that the image is quite dark and the colours are 
very dull.  There's too much apricot predominance in the image.  With 
Ekiga I can brighten it up to a somewhat satisfactory level, but Skype 
has no such capacity to brighten the image.

How might I change the code so that the default behaviour is to have it 
working at a certain brightness?
