VIP Gamma Corrector

Hi Nikki,

thanks for the reply!

So I guess the description on page 8 of an627 (UDX4 Reference Design) is an error. Or is it referring to a different Gamma Corrector?

Thanks for the advice about gamma correction, but due to many years of experience I do know what gamma correction is. :)

In the past years I have not seen anybody converting from gamma space to uncompressed space without increasing the color depth at the same time or converting it back into gamma space while reducing color depth.

It's basically necessary, because the conversion to uncompressed space is decompressing the colors.

For example: I have a DVI input and I want to scale that video to a higher resolution. Before I feed it through the scaler I would want to remove gamma, because the scaling result will be better, in part because of the increased resolution. To display the upscaled video on DVI I need to reapply gamma, thus reducing the resolution.

Anybody I have talked to (coworkers and such) does not see the point of this Gamma Corrector, simply because input and output color depths are the same.

But maybe we are just assuming it to be something it is not.
