Lookup Table
The 33U series allows the user to specify a lookup table (LUT) that can transform pixel
values. This lookup table can be used to perform tasks like histogram equalization
inside the camera.
If the pixel format of a color camera is set to one of the YUV modes, the lookup table is
applied only to the Y channel. In bayer raw and RGB24 modes, all color channels are
subject to the same lookup operation.
The lookup table has 257 16-bit entries. The upper 8 bits of the image data are used to
select the appropriate entry in the lookup table, while the remaining bits are used to
interpolate between the selected entry and one of its neighbors.
The
LUT Enable
feature enables the lookup table.
Parameter
