IMAGE FORMING APPARATUS, IMAGE FORMING SYSTEM, METHOD OF CONTROLLING SAID APPARATUS AND SYSTEM, AND PROGRAM Russian patent published in 2012 - IPC G03G15/00 

FIELD: physics.

SUBSTANCE: image forming apparatus has a conversion unit, having a plurality of pixels ordered in a matrix, each pixel having a converting element, an output switching element and an initialisation switching element; an output trigger circuit which triggers the output operation; an initialisation trigger circuit which controls the initialisation operation; and a reading circuit which performs a signal sampling and storage operation and a reset operation. The control unit completes the operation of outputting a defined row and begins the operation of outputting another row after completing the reset operation, begins the signal sampling and storage operation after completing the operation of outputting a defined row and begins the operation of outputting another row, begins the reset operation and the initialisation operation after completing the signal sampling and storage operation, and completes the reset operation after completing the initialisation operation.

EFFECT: design of an image forming apparatus which can obtain an image signal, having an excellent signal-to-noise ratio, thereby achieving the desirable frame time.
