14.5.2 CMD_SetBlendMapControlPoints [Opcode: 0x2E]

This command is used to pass the Horizontal (Hres) and Vertical (Vres) resolution of image and also the Horizontal and vertical control point’s location.

The values of the control point locations must in the range of 0 to (Hres – 1) for the horizontal control points and 0 to (Vres – 1) for the vertical control points.

The following example shows how this command can be used for an image of resolution 1280×1080 and the control points are evenly spaced.

Ideally, more control points are needed in the region where gain or offset change is required, but keep in mind the constraints mentioned before.

Note:

The 31st horizontal control point location is at the center of image horizontally.

Half of control point locations are in left half of image and other half in right half image.
