Previewer settings for Aptina sensor

Mitul Chokshi

Hello All,

I have interfaced Aptina MT9V024 color CMOS sensor with DM6437. And using Previewer for converting Bayer data to YUV.

For RGB Blending and RGB to YUV Conversion modules, I am using coefficients provided in example code.

But these coefficients are for Aptina MT9001, so there is small mismatch in reproduced color. Can anyone guide me on how can I get these settings for Mt9V024 sensor?

Thanks in advanced.

We do not provide tune tool for DM6437. So you'd have to tune the RGB2RGB blending matrix manually. RGB2YUV matrix does not need to be tuned since the coefficients are standard and should be kept the same at all times.

Hi Xiangdong,

Could you please tell us how to tune RGB2RGB blending matrix manually.

Is tuning a trial and error process or any standard method defined ??

Thank you.
