IMAGE PICKUP APPARATUS CAPABLE OF REDUCING INFLUENCE OF FLICKER, METHOD OF CONTROLLING THE SAME, AND STORAGE MEDIUM

摘要

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.

主权项

1. An image pickup apparatus comprising:
an image pickup unit; and at least one processor configured to perform: a first flicker detection for detecting, when a processing for obtaining a still image is performed, light amount change period of flicker based on a plurality of image data obtained by the image pickup unit; a second flicker detection for detecting, when a processing for obtaining a movie image is performed, light amount change period of flicker based on one image data obtained by the image pickup unit; a storage process for storing an information corresponding to the light amount change period based on a result of the second flicker detection into a memory; and a processing for suppressing flicker, on the image obtained by the image pickup unit, wherein, in a case where the information has been stored in the memory and the process shifts to the processing for obtaining the still image during the processing for obtaining the movie image, the processing for suppressing flicker is performed based on the information stored in the memory without the first flicker detection performed.
