Abstract
An image processing method includes the steps of acquiring a captured image generated through image capturing using an optical system, performing first shaping processing so as to reduce a difference between a maximum value and a non-maximum value for data generated using information of a point spread function of the optical system corresponding to an image capturing condition of the captured image, performing rotating processing according to a position of the captured image for the data after the first shaping processing, and performing sharpening processing of the captured image using the data after the rotating processing.
Claims21
An image processing method comprising the steps of:
- acquiring a captured image generated through image capturing using an optical system;
- performing first shaping processing so as to reduce a difference between a maximum value and a non-maximum value for data generated using information of a point spread function of the optical system corresponding to an image capturing condition of the captured image;
- performing rotating processing according to a position of the captured image for the data after the first shaping processing;
- and
- performing sharpening processing of the captured image using the data after the rotating processing.
An image processing apparatus comprising:
- an acquirer configured to acquire a captured image generated through image capturing using an optical system;
- a shaping processor configured to perform first shaping processing so as to reduce a difference between a maximum value and a non-maximum value for data generated using information of a point spread function of the optical system corresponding to an image capturing condition of the captured image;
- a rotation processor configured to perform rotating processing according to a position of the captured image for the data after the first shaping processing;
- and
- a sharpening processor configured to perform sharpening processing of the captured image using the data after the rotating processing.
