Part Number: DM385
We need to create a bitmap of the same size as captured frame, corresponding to each captured frame from ISS/HD-VPSS
The content of bitmap needs to be as per following requirement
- A range of YCbCr values will be provided
- Assuming the frame is of size 1920x1080, the bitmap will also be of size 1920x1080
- From each YUV buffer, we need to generate an output bitmap with 1’s in places where the pixel’s color fall in range of the YCbCr range given
- Rest of the bitmap value should be 0
The above requirement is essentially the part of Chroma-Keying where it figure outs which pixels needs to be blacked/faded out for blending.
Please let us know if DM385 supports the above requirement. We went through the HD-VPSS document and there it talks about support for chroma-keying, but beyond that no further information is given
