DA41990615R_1.0 25 1999 Hyundai System IC Division (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. Overall Frames Sequence MCLK ENB VSYNC Delay Slots Fig. 5 Initial Data Setup Time after ENB gets active ENB Deglitch 2 clocks Sensor Reset SensorArrayHeight clocks [314 clocks] One Line Time Delay (SensorArrayWidth + HBLANK) clocks [417 clocks] VSYNC 3 clocks Integration Time * Scale clocks [600 * 414 clocks] .... .... .... |
