Title:
IMAGE PROCESSING DEVICE, IMAGE CAPTURING DEVICE, AND IMAGE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/146060
Kind Code:
A1
Abstract:
Provided are an image processing device, an image capturing device, and an image processing method with which it is possible to obtain a captured image having a desired image quality. An image processing section (35) that functions as an image processing device comprises: a point image restoration processing section 51 that subjects image data obtained from an image capturing element (26) by capturing an image of a subject with a lens unit (12) including a lens (16) and an image capturing section including said image capturing element (26) to point image restoration processing employing a restoration filter based on a point spread function of the lens unit (12); and a determination section (53) that determines to perform the point image restoration processing by said point image restoration processing section (51) when a modulation transfer function, which changes depending on image capturing conditions and which is in a predetermined spatial frequency to which the point image restoration processing contributes, drops below a threshold. The point image restoration processing section (51) performs the point image restoration processing only in cases where the determination section (53) has determined to perform the point image restoration processing.
