ABSTRACT:
Basically, en electronic shutter function of a CMOS solid-state image pickup apparatus is implemented by a rolling shutter of which exposure timing sequentially shifts between pixel rows. The exposure period for one pixel row is from a time point when readout of the pixel row is started to a time point when next readout of the pixel row is started. Thus, in order to achieve exposure similar to that of a global shutter with the same exposure period applied to all of the pixel rows, there is set a blank period where no pixel signal is read out from any one of the pixel rows, and an LED is illuminated over a predetermined portion within the blank period. In this way, the CMOS solid-state image pickup apparatus having a rolling shutter function can achieve similar exposure to a global shutter.
