Patent ID: 10699387

Abstract:
Provided are an image processing device, an imaging device, and an image processing method which are capable of obtaining a captured image with desired image quality. An image processing unit functioning as an image processing device includes a point image restoration processing unit that performs point image restoration processing using a restoration filter based on a point spread function of a lens unit on image data obtained from an imaging element through imaging of a subject using an imaging unit having the lens unit including a lens and the imaging element, and a determination unit that determines to perform the point image restoration processing using the point image restoration processing unit in a case where a modulation transfer function in a predetermined spatial frequency in which the point image restoration processing contributes is smaller than a threshold value. Here, the modulation transfer function is changed by an imaging condition. The point image restoration processing unit performs the point image restoration processing only in a case where the determination unit determines to perform the point image restoration processing.
