IMAGING DEVICE AND IMAGING METHOD

摘要

Provided are an imaging device and an imaging method which can realize an appropriate modulation pattern in accordance with a zoom position without requiring a modulation element switching mechanism in a depth extension optical system. The imaging device includes: a zoom optical system (110) having an optical wavefront modulation element (114) which has an optical wavefront modulation function and can adjust the optical wavefront modulation pattern; an imaging element (120) for capturing an object image which has passed through the zoom optical system; a modulation function (pattern) control unit (200) which controls the optical wavefront modulation pattern of the optical wavefront modulation element; and an image processing unit (140) which performs a predetermined processing on an image signal of the object from the imaging element (120). The zoom optical system (110) is a lens-moving type for moving a lens in the optical axis direction. The modulation function (pattern) control unit (200) controls the optical wavefront modulation pattern of the optical wavefront modulation element in accordance with information on the lens operation in the zoom optical system.
