Imaging device and focusing control method
Abstract:
The present invention provides an imaging device and a focusing control method capable of reliably preventing the accuracy of a focusing control from being lowered even in a case where a signal level of a phase difference detection pixel is low. A system control unit (11) calculates, using detections signals of phase difference detection pixels (52A, 52B) obtained by each of two instances of imaging which are consecutively performed by an imaging element (5), first defocus amounts for each instance of imaging, adds up detection signals corresponding to the detection signals of the phase difference detection pixels (52), among captured image signals obtained by each of two instances of imaging, calculates a second defocus amount using signals after addition, and compares the plural of first defocus amounts and the second defocus amount to determine whether to perform a focusing control based on the second defocus amount.
