Y - Luminance average (12 bit)
Note: The exposure statistic is measured in 5x5 (25) sub-windows which results into 25
mean luminance/exposure values. The width of a sub-window is resolution width divided
by 5. The height of a sub window is resolution height divided by 5.
Following table shows the numbering of the statistic values:
Y0 Y1 Y2 Y3 Y4
Y5 Y6 Y7 Y8 Y9
Y10 Y11 Y12 Y13 Y14
Y15 Y16 Y17 Y18 Y19
Y20 Y21 Y22 Y23 Y24
