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
(see
result is readable as one byte through the I
values are each represented by 8-bit.
