ABSTRACT:
From a pixel array where imaging pixels are arranged, pixel signals of respective columns on a selected row are read in parallel in a horizontal blanking period of a horizontal period. The pixel signals of the respective columns are output to horizontal signal lines in an effective period of the horizontal period via charge integrating amps provided respectively for the columns, i.e., provided respectively for vertical signal lines, and are thereby transferred horizontally. In the charge integrating amps, it is possible to enter a standby state while holding the pixel signals by a holding voltage. Furthermore, in the charge integrating amps, a reference potential for precharging feedback capacitors for amps at the time of a reading operation is automatically controlled based on a black level. Furthermore, pixel signals from the respective charge integrating amps are horizontally transferred in parallel using a plurality of horizontal signal lines.
