Photosensitive cell control

摘要

The process involves isolating a photodiode from a reference potential at end of a wait state, by setting a transfer transistor when initialization transistor is blocked, and setting the initialization transistor when transfer transistor is blocked. Voltage of the photodiode is varied from an initialization voltage to a useful voltage during an integration phase. A voltage reading phase represents the useful voltage. An independent claim is also included for a device of controlling a photosensitive cell.
