This register sets the range of the images to be written (captured) to the video capture buffer. Specify
the X coordinates located in the top left of the image range as the count of pixels from the top left of the
image. For reduction, 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 Y coordinates located in the top left of the image range as the count of pixels from the top left of the
image. For reduction, 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 reduction, 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 reduction, apply this setting to the post-reduction image
coordinates.
If the count of rasters of the input image is less than the range set by this command, data is written
only at the size of the input image.
