Facing Problem with Camera ISP Resizer

Other Parts Discussed in Thread: OMAP3530

I am using TI EVM 35xx Board and the BSP Version is 6.12.03.

I am facing problem in camera isp resizer, the output image from the resizer looks much exposed(i.e. image is more brighter than the actual image).

Input image type is UYVY packed format and the input to resizer is from memory.

I am using the filter co-efficient value given in the sample camera driver code given with the BSP(in V6.12 BSP).

This is my actual image which is sent to the resizer

and the output image i got from the resizer is this

The Luminance enhancer algorithm selection is disabled(in RSZ_YENH).

Is this problem related to the filter co-efficient value?

Is there any document available for filter co-efficient calculation?

thanks,

sarathy

    I have the exactly the same problem ( image is more brighter than the image without resizer) except  that the input to resizer is from previewer.

    I am running this on Windows Mobile.

    Also, I wonder are there any sample settings for the omap3530 resizer luma enhancer?

    Thanks
