PROBLEM TO BE SOLVED: To provide an imaging device and an imaging method which can realize an appropriate modulation pattern, according to zoom position, without requiring a modulation element switching mechanism in a depth-extension optical system. SOLUTION: 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 predetermined processing on an image signal of the object from the imaging element 120. The zoom optical system 110 is a lens-moving type that makes a lens move in the optical axis direction, and the modulation function (pattern) control unit 200 controls the optical wavefront modulation pattern of the optical wavefront modulation element, according to the information regarding the lens operation in the zoom optical system.
