Abstract:
1. A camera module comprising: an imaging unit which is configured to include pixel cells arranged in an array shape and images an object image; a first imaging optical system which takes in a light from an object to the imaging unit; a second imaging optical system which forms an image piece corresponding to a portion of the object image in each pixel block which is configured to include a plurality of the pixel cells; a focus adjustment unit which performs focus adjustment of the first imaging optical system; and an imaging mode control unit which controls driving of the second imaging optical system and the focus adjustment unit in a first imaging mode and a second imaging mode, wherein in the first imaging mode, the imaging mode control unit allows the second imaging optical system to function in an optical path between the imaging unit and the first imaging optical system and stops the focus adjustment of the focus adjustment unit, in the second imaging mode, the imaging mode control unit stops the function of the second imaging optical system and allows the focus adjustment unit to perform the focus adjustment, when a mode is changed from the second imaging mode to the first imaging mode, the focus adjustment unit moves the first imaging optical system based on control of the imaging mode control unit, an incidence plane of the second imaging optical system being coincident with an image forming plane of the first imaging optical system which has been moved, and when a mode is changed from the first imaging mode to the second imaging mode, the focus adjustment unit moves the first imaging optical system based on control of the imaging mode control unit, a light receiving plane of the imaging unit being coincident with the imaging forming plane of the first imaging optical system which has been moved.
