ABSTRACT:
A solid-state image pickup device and a still picture recording device in which blooming and vertical smearing are eliminated. A drive circuit applies vertical and horizontal synchronizing signals to an image pickup element or area image sensor, and an exposure control circuit applies an exposure time control signal thereto for controlling the length of the exposure time according to the intensity of the image light exposing the pickup element or sensor. A scanning stopping circuit stops the application of the synchronizing signals to thereby stop the scanning of the area image sensor for a period of time starting from a time before the start of exposure until the occurrence of a first pulse of the vertical synchronizing signal after application of the exposure time control signal.
