<p>An image sensor control device includes an image sensor including focus detecting pixels; an object brightness detecting unit that detects brightness of an object; a mode determining unit that determines a first readout mode or a second readout mode based on the detected brightness of the object; a read-out unit that reads out the focus detecting pixels in the determined readout mode; and a focus detecting unit that performs focus detection by using focus detection data read out from the focus detecting pixels. In the first readout mode, the read-out unit reads out the focus detecting pixels after a first charge accumulation period, and, in the second readout mode, the read-out unit reads out the focus detecting pixels after a second charge accumulation period, which is longer than the first period.</p> |
