20.4.2 Description
Phase 0
During T1 all pixels are integrated until they reach the defined signal level of Knee Point 1. ♦
If one pixel reaches the level, the integration will be stopped. ♦
During T1 no pixel can reached a level higher than P1. ♦
•
Phase 1
During T2 all pixels are integrated until they reach the defined signal level of Knee Point 2. ♦
T2 is always smaller than T1 so that the percentage compared to the total exposure time is
lower. ♦
Thus, the signal increase during T2 is lower as during T1. ♦
The max. signal level of Knee Point 2 is higher than of Knee Point 1. ♦
•
Phase 2
During T2 all pixels are integrated until the possible saturation. ♦
T3 is always smaller than T2, so that the percentage compared to the total exposure time is
again lower here. ♦
Thus, the signal increase during T3 is lower as during T2. ♦
•
For this reason, darker pixels can be integrated during the complete integration time and the sensor reaches its
full sensitivity. Pixel's, which are limited at each Knee Points, lose a part of their integration time - even more,
if they are brighter.
