An imaging device of the present invention includes a normal operation period and a focusing operation period; a CCD (102) able to mix image signals of a plurality of pixels and read the mixed image signals; an AFE (103) that converts the image signals to image data; a signal processing unit (104b) that converts the image data to display data; an LCD (107) that displays the display data; and a pixel mixing control unit (104c) that changes a read frame rate and pixel mixing number of the CCD (102). The pixel mixing control unit (104c) performs control so that in the focusing operation period, the image signals are read from the CCD (102) at a higher read frame rate than in the normal operation period, and performs control so that in the focusing operation period, the image signals are read from the CCD (102) at a larger pixel mixing number than in the normal operation period. This structure enables providing an imaging device in which a high-speed focusing operation can be performed even if an imaging subject is dark.
