摘要： An apparatus includes a first capturing unit configured to obtain a first image; and a second capturing unit configured to obtain a second image having a wider angle of view than an angle of view of the first image. The apparatus controls each of a first display device corresponding to one eye of a user and a second display device corresponding to the other eye of the user to display an image based on the first image or the second image. In a case where no subject exists in the first image, the apparatus causes at least one of the first display device and the second display device to display the second image.

摘要： A focus detection sensor includes a line sensor comprised of a pair of sensor arrays in which a plurality of pixels are arranged. The sensor arrays include a pixel of a first type having an arrangement for transferring charges generated by a photoelectric conversion device to a corresponding memory device and causing the memory device to integrate the charges during a charge accumulation period, and a pixel of a second type having an arrangement for integrating, in the pixel, the charges generated by the photoelectric conversion device during the charge accumulation period without transferring the charges to the memory device until the end of the charge accumulation period, and transferring the charges to the corresponding memory device when the charge accumulation period has ended. An accurate charge accumulation result can be obtained by a simple arrangement.

The apparatus includes a signal generation unit configured to output a pair of image signals from a focus detection region having a plurality of corresponding display regions, the image signals being generated by photoelectrically converting light having passed through an imaging optical system, and a control unit configured to detect a phase difference of the pair of image signals output from the focus detection region, and to control a position of the focus lens based on the phase difference detection result. The control unit detects the phase difference corresponding to divided regions formed by dividing the focus detection region, and displays an in-focus state in the display region in accordance with the control of the focus lens position control based on the phase difference detection result.
