Very dark front camera on my N900!!
 

I was wondering if there is a script or app that will permit me to change the brightness and contrast on my N900 front camera?!

Re: Very dark front camera on my N900!!
 

yeah...i would like to know also. the front camera is pretty terrible

Re: Very dark front camera on my N900!!
 

Even with the default Kernel PR1.3 the results are horrible..!!Any suggestion??

Re: Very dark front camera on my N900!!
 

There is a configuration file you can change to adjust contrast and brightness, but I haven't got a clue where it is, sorry.

Re: Very dark front camera on my N900!!
 

We need that file..!Hope that someone wanna help us on this!

agree with you all but what are you guys using iy for? internet call? or does 3g video call works in pr 1.3? i saw somewhere in setting saying show 3g/video call option. one of the service provider in my country started offering video calls at rate of normal call but sad my n900 is just like those iphones with kind of useless front cam(not doing itd primary function).

Ok...the other day i was looking to make a video call with one of my friend via Skype video call, but i noticed that the quality was so bad i can hardly see my self in there and u must imagine that i was in a well lighted room!!

PS: With PR 1.2 wasn`t much better but lets say it was ok!!

To change the brightness and contrast of front camera

gst-launch v4l2src device=/dev/video1 ! ffmpegcolorspace ! videobalance brightness=0.5 contrast=1.2 ! autovideosink

The "brightness" property

Allowed values: [-1,1] Default value: 0

The "contrast" property

Allowed values: [0,2] Default value: 1


You might need to install gstreamer0.10-plugins-good-extra for the video balance pipeline to be present.

Apparently you can change gamma too but I've not found that yet.

BTW I found all this using power search and searching the terms 'front brightness', just so you know.

I had searched before i post here and had found this solution too..Tried to play with some different values but with no luck to get a good result..Can u tell me the values u use now?

PS: Gamma will do the trick i think!

Tried again a variety of different values for brightness and contrast.Cant get a good result..Forgot to mention that all i get looks like i am using a night vision scope..all has a tint of green and black!
