Detection apparatus, image capturing apparatus, control method, and recording medium

An image capturing apparatus, comprising:

• an image sensor;
• a first obtainment unit configured to obtain a plurality of captured images related to a subject by performing image capture continuously with use of the image sensor;
• a determination unit configured to determine whether a capturing field angle has changed due to an operation of an image stabilizing mechanism during the image capture for the plurality of captured images;
• and
• a detection unit configured to detect whether flicker of a predetermined level has occurred based on the plurality of captured images obtained by the first obtainment unit,
• wherein in a case where the determination unit has determined that the capturing field angle has changed due to the operation of the image stabilizing mechanism during the image capture for the plurality of captured images, the detection unit restricts regions in the plurality of captured images used for detecting whether the flicker of the predetermined level has occurred.

A control method for a detection apparatus that detects whether there is flicker attributed to a light source, the control method comprising:

• obtaining a plurality of captured images related to a subject by performing image capture continuously with use of an image sensor;
• determining whether a capturing field angle has changed due to an operation of an image stabilizing mechanism during the image capture for the plurality of captured images;
• and
• detecting whether flicker of a predetermined level has occurred based on the plurality of captured images obtained in the obtaining,
• wherein in a case where it has been determined, in the determining, that the capturing field angle has changed due to the operation of the image stabilizing mechanism during the image capture for the plurality of captured images, the detecting restricts regions in the plurality of captured images used for detecting whether the flicker of the predetermined level has occurred.
