In a still image pickup apparatus of the kind arranged to start an exposure by causing an image sensor to begin an accumulating action and to end the exposure by using a light-shielding member having a poor responsivity, the exposure time is arranged to be controlled by allowing the accumulating action of the image sensor to begin after the light-shielding member starts the light-shielding action for terminating the exposure time. This arrangement enables the apparatus to perform a high-speed shutter operation irrespectively of the responsivity of the light-shielding member.
