Abstract
A temperature detection section detects the temperature of an imaging lens. A control section sets a focal point change correction amount for a distance from the imaging lens to an imaging surface of an imaging element, on the basis of the temperature at the time of focusing and the current temperature that are detected by the temperature detection section, and a signal reading range according to an imaging mode on the imaging surface of the imaging element where a subject optical image is formed by the imaging lens. A distance adjustment section performs an adjustment according to the focal point change correction amount set by the control section, on the distance from the imaging lens to the imaging surface at the time of focusing. Obtain a picked-up image restrained from being lowered in resolution, irrespectively of the temperature change of the imaging lens or switching of the imaging mode.
