ABSTRACT:
A solid-state image-sensing device that compensates for brightness at edges of a screen and a method of driving the device are provided. The solid-state image-sensing device comprises: an active pixel sensor (APS) array including pixels disposed in a two-dimensional matrix, each pixel for outputting a photoelectrically converted image signal generated by a photodiode in response to one of a plurality of transmission control signals transmitted to a selected row of the APS array, and for generating and outputting a reset signal in response to a reset control signal; a row driver for selecting a row of the APS array by generating row selection signals and for generating the reset control signal; an integration time control driver for generating the transmission control signals for setting non-uniform integration times of the photodiodes in each pixel; and an analog-digital converter for converting an analog signal corresponding to a difference between the image signal and the reset signal into a digital signal.
