The exposure time is defined as the interval from the cell pre-charge to the end of the photo-induced current measurement and can be controlled manually or by using the AEC function.
Simpo PDF Password Remover Unregistered Version - http://www.simpopdf.com 4-5 Since the exposure time AEC[15:0] is based on row interval, the AEC needs to know 1/100 second and 1/120 second is equal to how many rows. Banding filter registers, BD50st and BD60st, are used to set 1/100 and 1/120 second.
