RGB values from bayer format, how has it been done?

[arvind]

i understand that avrcam dumps the image to avrcam viewpc application in bayer format. How then is it that, when the pointer is taken over any pixel of the image, RGB values of that pixel is displayed?
How are the RGB values for each pixel obtained from the bayer format?

The AVRcamVIEW PC application is doing a bilinear interpolation (which is just a fancy way of saying that it does some averaging of the R/G/B values around a particular pixel) to determine an actual RGB value for each pixel in the image being displayed on the PC. Thus, when you scroll your mouse over the image, this is the triplet being displayed to the user.

hey did u try any other interpolation(nearest neighbour etc..) apart from bilinear?what was the performance like?
And also has white balancing been done?if so how?
