Image capturing apparatus and control method for image capturing apparatus with particle filter for main object detection and selecting focus detection area based on priority

摘要

Focus detection can be performed preferentially in an area that is likely to include a main object. An image capturing apparatus is configured to detect a main object in an image with a particle filter, divide the image into divided areas respectively corresponding to a plurality of focus detection areas, set a priority to each of the focus detection areas based on a distributed state of particles distributed in each of the divided areas, and select the focus detection area based on the set priority.
