This register sets the range of the images to be written (captured) to the video capture buffer.
Specify the Y coordinates located in the top left of the image range as the count of pixels from the
top left of the image. For downscaling, apply this setting to the post-reduction image coordinates.

This register sets the range of the images to be written (captured) to the video capture buffer.
Specify the X coordinates located in the bottom right of the image range as the count of pixels from
the top left of the image. For downscaling, apply this setting to the post-reduction image
coordinates.
If the pixel at the right end of the image is not aligned on 64 bits/word boundary, extra data is
written before 64 bits/word boundary.
If the width of the input image is less than the range set by this command, data is written only at the
size of input image.

This register sets the range of the images to be written (captured) to the video capture buffer.
Specify the Y coordinates located in the bottom right of the image range as the count of pixels from
the top left of the original image to be input. For downscaling, apply this setting to the post-
reduction image coordinates.
