There is provided an image pickup apparatus having a simple structure that enables reduction of shutter release time lag and shutter control with highly accurate shutter time. The apparatus comprises an image pickup element that converts an optical object image incident thereon into an electric image signal to output it, a shutter apparatus having a screen for shielding an exposure aperture for the image pickup element, a reset circuit for reset scanning the image pickup element on a predetermined unit-batch-by-unit-batch basis sequentially in a running direction of the screen, a plurality of detection circuits disposed at different positions along the running direction of the screen for detecting passing of the screen after start of running of the screen for shielding the exposure aperture and before it runs over the exposure aperture, and a control circuit that estimates a running characteristic of the screen during running based on a detection result by the plurality of detection circuit and controls reset scanning by the reset circuit in conformity with the estimated running characteristic.
