Information processing apparatus, image capturing apparatus, information processing method, and non-transitory computer-readable storage medium

An information processing method of controlling an image capturing apparatus including a photoelectric conversion element configured to generate an image signal by counting a pulse signal corresponding to incidence of light, the method comprising:

• controlling an exposure period of a main frame based on a main period as the exposure period of the main frame;
• detecting an object blur for each unit period shorter than the main period by reading out an image signal of an exposed sub-frame for a sub-period from a start of exposure to an end of the unit period;
• and
• outputting, based on a result of the blur detection, an output signal based on an image signal selected from one of the main frame and the sub-frame.

A non-transitory computer-readable storage medium storing a computer program that, when read and executed by a computer for controlling an image capturing apparatus including a photoelectric conversion element configured to generate an image signal by counting a pulse signal corresponding to incidence of light, causes the computer to:

• control an exposure period of a main frame based on a main period as the exposure period of the main frame;
• detect an object blur for each unit period shorter than the main period by reading out an image signal of an exposed sub-frame for a sub-period from a start of exposure to an end of the unit period;
• and
• output, based on a result of the blur detection, an output signal based on an image signal selected from one of the main frame and the sub-frame.
