Abstract
An image pickup apparatus capable of generating a strobe emission signal in a proper timing even when an electronic front curtain shutter is used in strobe photographing. The image pickup apparatus includes an image pickup device having pixels arranged in matrix and configured to store charges generated according to a received amount of light. A vertical scanning circuit controls travel of the electronic front curtain shutter such that the image pickup device sequentially receives light on a per line basis, starting from a first scan line. When it is detected that the electronic front curtain shutter reaches a predetermined scan line, a NOR gate outputs a light emission timing signal, whereby light is emitted from a light emission unit such as a strobe.
