The AF sensor 150 includes a plurality of photoelectric conversion element arrays that receive a part of a subject light beam guided from a half mirror or the like. The AF sensor 150 outputs a signal with a phase match when in the in-focus state, and outputs a signal with a phase shift when in the front pin state or the rear pin state. The amount of phase shift corresponds to the amount of shift from the focus state. The AF sensor 150 detects a phase difference by performing a correlation operation on the output of the photoelectric conversion element array, and outputs a phase difference signal indicating the phase difference to the AF control unit 151.

  The AF control unit 151 outputs a control signal for moving the focus lens 122 to an appropriate target position to the lens system control unit 120 by the phase difference AF method or the contrast AF method. Specifically, when control is performed using the phase difference AF method, the AF control unit 151 determines the target position of the focus lens 122 based on the focus state detected from the phase difference signal output from the AF sensor 150. Then, the position of the focus lens 122 is moved by the control of the lens system control unit 120 toward the determined target position.

  When control is performed using the contrast AF method, the AF control unit 151 detects a position where the contrast of the subject image increases from the image data from the A / D converter 135. The AF control unit 151 outputs a control signal to the lens system control unit 120 to detect the position where the contrast of the subject image increases while moving the focus lens 122, and moves the focus lens 122 to the detected position. . In such a contrast AF method, focus control can be performed from an image captured by the image sensor 133. Therefore, the AF control unit 151 can perform control by the contrast AF method, for example, when a live view image is displayed on the electronic viewfinder.
