7.6.1.4 Histogram collection
The histogram collection provides the following features:
Three programmable LUTs (each having 17
realize piecewise (16 segments) linear transfer characteristics for Y-C
Evaluation of the statistical appearance of luminance sample codes over a programmable
observation window (maximum of 2 interlaced video fields) by the system microcontroller
can be utilized to load values s0 to s16 for the segments of the LUTs accordingly
