10. Exposure Time

The high exposure setting (249) sets an exposure time of 249 lines, which means that while one row is being read, (249 are integrating and only 1 in reset), making a total of integration time of 22.7 ms.

Roughly the integration time is give by the following formula:

Integration time = Exposure x 90.8 us


The effective exposure time thus is given by the formula:

Texp =((Nrows – Nrows_reset)/Nrows)*Ftime


Is not recommended to use exposure setting 250, (max. integration time), it can lead to additional noise and unstable image. Each additional exposure step decreases the exposure time by 90.8ns (equivalent of the exposure time of one line).
