(2) Frame Timing Diagram for Integration Time > (EffectiveWindowHeight * Scale)
Frame timing related registers are programmed to suit for the above condition as follows
RowStartAddress = 6; WindowHeight = 302;
ColumnStartAddress = 6; WindowWidth = 402;
IntegrationTime = 600 [Line Mode];
EffectiveWindowHeight is “302” for (SensorArrayHeight > (RowStartAddress + WindowHeight + 1)), i.e. 314 > (6
+ 302 + 1), is met, and Scale is “1” for integration time is line mode. Therefore, (Integration Time <
EffectiveWindowHeight * Scale), i.e. 600 > 302 * 1, is met, and Idle Slot of Line Mode, i.e. (600 - 302) * 1024
clocks idle slot, is inserted before the next frame initiation.
