Abstract
A system for controlling photosensitive charge transfers utilizes an array of photosensitive elements, a transfer gate, a charge transfer register, and a controller. The transfer gate is coupled to the photosensitive elements, and the charge transfer register is coupled to the transfer gate. The charge transfer register is configured to receive charges from the array of photosensitive elements, via the transfer gate, and to shift the charges out of the charge transfer register. The controller is configured to control the transfer gate such that charges are collected in each of the photosensitive elements and transferred, via the transfer gate, to the charge transfer register. The controller is further configured to enable the transfer gate during a time period when the charge transfer register is shifting a set of charges previously transferred from the array of photosensitive elements to the charge transfer register.
