Abstract
An image pickup apparatus capable of reducing influence of flicker while suppressing delay of start of photographing. An image pickup device and a photometric sensor pick up images of an object. A CPU obtains images by controlling driving of one of the device and the sensor to perform charge accumulation and charge readout. Further, the CPU detects a flicker frequency and a flicker phase of a flicker light source, and stores them in a memory as first information. When photographing, if the CPU determines that the first information is not valid, an ICPU obtains images by controlling driving of the other of them to perform charge accumulation and charge readout. Further, the ICPU detects the flicker frequency and the flicker phase and stores them in a memory as second information. The CPU controls exposure timing according to the second information to perform photographing.
