Loading An Lut Into The Camera - AVT Pike Technical Manual

Description of the data path

Loading an LUT into the camera

Loading the LUT is carried out through the data exchange buffer called
GPDATA_BUFFER. As this buffer can hold a maximum of 2 kB, and a complete
LUT at 16384 x 14 bit is 28 kByte, programming can not take place in a one
block write step because the size of an LUT is larger than GPDATA_BUFFER.
Therefore input must be handled in several steps. The flow diagram below
shows the sequence required to load data into the camera.
Query limits from
