autoBrightnessOffsetY = Trunc (CustomerEnteredStatisticOffsety/2) *2

Given that autoBrightnessOffsetY >=O2 and autoBrightnessOffsetY <=Hieght-2-

autoBrightnessHeight

autoBrightnessOffsetx = Trunc((CustomerEnteredStatisticOffsetx)/32)*32 +1 Width must first be

reduced before the offsetx can be increased.

autoBrightnessOffsetx <= 10720- autoBrightnessWidth

autoBrightnessWidth = Trunc(CustomerEnteredWidthx/32)*32>=64 <= 10720
