Second Set of Bin Definitions
7:0
Offset for bin 0, divided by 4 on 10-bit scale.
10:8
Bin width, 0-4LSB,1-8LSB,2-16LSB,…7-512LSB on a 10-bit scale.

Histogram Window Size
12:0 1
Number of pixels in the window used by the histogram, set to width*height.

Pixel Counts for Bin 0 and Bin 1
7:0
Pixel count for bin 0 (lowest values) divided window size, R215:2.
15:8
Pixel count for bin 1 divided by window size, R215:2.
Histogram module uses luma after interpolation. No color correction or gamma is applied. Digital gains and first
black level are applied.
This register may not be read out when image portion containing histogram window is being output.
There are two bin sets which could be read through registers 216 and 217, based on value of bit 13 in reg 215[2].

Pixel Counts for Bin 2 and Bin 3
7:0
Pixel count for bin 2 divided by G factor.
15:8
Pixel count for bin 3 (highest values) divided by G factor.
