1. A camera which executes autofocus adjustment using pixel data acquired from an image capturing device, comprising:

  • a first transfer unit which transfers, in a first transfer time, pixel data of a first pixel range of a plurality of pixel data that are acquired by exposure of the image capturing device;

    a second transfer unit which transfers, in a second transfer time that is shorter than the first transfer time, pixel data of a second pixel range of the plurality of pixel data that are acquired by exposure of the image capturing device, a number of pixels of the second pixel range being less than a number of pixels of the first pixel range;

    a first control unit which causes the first transfer unit to successively transfer the pixel data, successively updates a display screen for conformation of a subject on the basis of the pixel data that is successively transferred by the first transfer unit, and controls the autofocus adjustment on the basis of the pixel data that is successively transferred by the first transfer unit;

    a second control unit which causes the second transfer unit to successively transfer the pixel data, interrupts the updating of the display screen for the conformation of the subject while the pixel data is being transferred by the second transfer unit, and controls the autofocus adjustment on the basis of the pixel data that is successively transferred by the second transfer unit; and

    a control determination unit which determines whether the autofocus adjustment is to be controlled by the first control unit or the second control unit.
