Image pickup apparatus capable of performing image pickup with reduced flicker influence, method for controlling the same, and storage medium

An image pickup apparatus including an image sensor and display unit configured to display a live view of images picked up by the image sensor, the image pickup apparatus comprising:

• at least one processor or circuit configured to perform the operations of the following units:
• detection unit configured to perform a flicker detection operation to detect flicker based on a plurality of images captured by the image sensor at predetermined intervals;
• and
• control unit configured to control the image sensor based on flicker information detected by the detection unit,
• wherein the detection unit is configured to perform first detection of the flicker detection operation at a time that is different from a time at which an image pickup preparation instruction is received and different from a time at which an image pickup instruction is received whilst live view images are displayed on the display unit, and
• wherein, in the case that a flicker is detected in the first detection, the control unit is configured to control exposure of the image sensor in a charge accumulation period to reduce an influence of the flicker for live view display on the display unit after the first detection.
