Claim Text:
1. An imaging device which includes an imaging element having a phase difference detection pixel formed therein that generates a focus detection signal by pupil-dividing and photoelectrically converting a light flux from a photographing optical system, and which performs autofocus using a plurality of AF areas each including a plurality of sub-areas that is obtained by dividing the AF area, the imaging device comprising: a calculation section configured to perform correlation calculation based on a focus detection signal corresponding to each of the plurality of sub-areas and output a degree of reliability; an AF area selection section configured to select an AF area including a large number of sub-areas in each of which the degree of reliability calculated corresponding to the plurality of sub-areas is higher; a moving body prediction calculation section configured to perform moving body prediction calculation using distance measurement data that is calculated by the correlation calculation based on a focus detection signal of the selected AF area; and a focus control section configured to perform focus adjustment based on a result of the moving body prediction calculation.
