Imaging apparatus and method of controlling the same and non-transitory computer-readable storage medium

A method of controlling an imaging apparatus which include:

• a storage circuit configured to store a plurality of correction values;
• a correction circuit configured to correct captured image data based on the correction values;
• a first memory and a second memory incorporated in the correction circuit;
• a transferring circuit configured to transfer the correction values stored in the storage circuit to the correction circuit;
• and
• a write circuit configured to write the correction values transferred by the transferring circuit to either the first memory or the second memory,
• the method comprising:
• controlling, in a case where a transfer time of the correction values transferred by the transferring circuit is longer than a time for image capture processing of one frame, so that, over an image capturing period of a plurality of frames, the write circuit writes new correction values to one of the first memory and the second memory and reads current correction values stored in the other memory, and the correction circuit corrects the captured image data.

A non-transitory computer-readable storage medium storing a program which, when read and executed by a computer, causes the steps of a method of controlling an imaging apparatus which include:

• a first memory and a second memory incorporated in the correction circuit;
• a transferring circuit configured to transfer the correction values stored in the storage circuit to the correction circuit;
• and
