<P>PROBLEM TO BE SOLVED: To reduce an occurrence of dark shading and fixed pattern noise. <P>SOLUTION: A solid-state image sensor has a pixel, a vertical signal line, and a control unit. The pixel comprises; a photoelectric conversion part which converts light into a charge; a charge-voltage conversion part; a transfer transistor which transfers the charge of the photoelectric conversion part to the charge-voltage conversion part; an amplifying transistor which generates a signal based on a voltage of the charge-voltage conversion part; a selection transistor which selects whether or not to output the signal; and a reset transistor which resets a charge of the charge-voltage conversion part. The charge-voltage conversion part is connected to the amplifying transistor and the reset transistor by a connection wiring. The signal output from the amplifying transistor is transmitted to the vertical signal line. The control unit controls the reset transistor and the selection transistor so that the selection transistor is in the on state when the reset transistor changes from the on state to the off state during the reset period in which a charge of the photoelectric conversion part is reset. <P>COPYRIGHT: (C)2012,JPO&INPIT |
