Imaging apparatus and control method thereof

An imaging apparatus having an imaging unit that has a plurality of pixel portions and a memory unit having a buffer function that stores image signals of a plurality of frames based on the data of the pixel portions comprising:

• a controller having a processor which executes instructions stored in a memory or having circuitry, the controller being configured to function as:
• a determination unit configured to determine a frame to be used for a moving image that corresponds to a timing at which an instruction to capture a still image has been provided from a plurality of frames stored in the memory unit;
• and
• a control unit configured to perform control in which an image signal of a frame to be used for the moving image determined by the determination unit is output to a storage destination,
• wherein at least a part of an exposure period of time of the frame to be used for the moving image determined by the determining unit overlaps with an exposure period of time of a frame to be used for a still image that corresponds to the timing.

A control method executed by an imaging apparatus having an imaging unit that outputs data of a plurality of pixel portions by a first stream and a memory unit having a buffer function that stores image signals of a plurality of frames based on the data, the method comprising:

• acquiring still image data corresponding to a timing at which an instruction to capture a still image has been provided by a second stream that is different from the first stream in the imaging unit;
• determining a frame to be used for a moving image that corresponds to the timing from a plurality of frames stored in the memory unit;
• and
• performing control in which an image signal of a frame to be used for the determined moving image is output to a storage destination.
