Abstract: An object determining apparatus includes a memory storing instructions, and a processor configured to execute the instructions to detect an object from image data obtained by imaging, acquire information about orientation of the object from the image data, determine a main object in the image data using a detection result of the object and the information about the orientation, and change a condition for determining the main object according to one of the detection result of the object and the information about the orientation, using the other of the detection result of the object and the information about the orientation.

Abstract: An apparatus configured to perform focus tracking on an object within a detection area to detect a defocus amount within an imaging angle of view includes a memory storing instructions, and a processor configured to execute the instructions to perform focus tracking determination to determine whether or not the focus tracking is to be performed using information about the defocus amount, and acquire information about a shield against the object from image data generated by imaging. The processor is configured to perform the focus tracking determination using information about the shield acquired in the detection area.

Abstract: A focusing apparatus includes a determination unit configured to determine whether an object is a moving object, and a focusing unit configured to perform focusing using information on driving of the focus lens generated based on the focus detecting signal in response to an operation of an operation unit. The determination unit determines whether the object is the moving object, using a first threshold before the operation of the operation unit, and using a second threshold different from the first threshold after the operation of the operation unit. The focusing unit performs first focusing that continuously performs the focusing when the determination unit determines that the object is the moving object before the operation of the operation unit, and performs the first focusing when the determination unit determines that the object is the moving object after performing second focusing that performs the focusing once.

Abstract: An apparatus includes a calculation unit that calculates a plurality of defocus amounts corresponding to a plurality of focus detecting frames obtained by dividing an area corresponding to a display frame, and a selection unit that selects one focus detecting frame which corresponds to one defocus amount used for an AF control. The selection unit changes an AF operation for selecting the one focus detecting frame based on the number of low contrast frames to the number of focus detecting frames or based on reliability selected from part of the area and a ratio of focus detecting frames having a high reliability in the area, or performs an AF operation for selecting the one focus detecting frame so that a high contrast frame is prioritized over a low contrast frame.
