Image processing apparatus and method
First Claim
1. An image processing method of processing an image obtained using an optical system having a wide field angle and a large magnification chromatic aberration, said method comprising the steps of:
- applying magnification chromatic aberration correction processing to the image;
applying separation processing to the image after the step of applying the magnification chromatic aberration correction for separating the image into a brightness signal and a color signal; and
applying a high band emphasis processing only to the brightness signal after the step of applying the separation processing.

Abstract
An image processing method of processing an image obtained by using an optical system having a wide field angle and a large magnification chromatic aberration includes the steps of applying magnification chromatic aberration correction processing to the image, applying separation processing to the image after the step of applying the magnification chromatic aberration correction for separating the image into a brightness signal and a color signal, and applying a high band emphasis processing only to the brightness signal after the step of applying the separation processing.

11. An image processing apparatus for processing an image obtained by an optical system having a wide field angle and a large magnification chromatic aberration, comprising:
-
a magnification chromatic aberration correction device configured to correct magnification chromatic aberration per color component by converting a coordinate of the image; a separation device configured to separate the image subjected to the magnification chromatic aberration correction into brightness and color signals; and a MTF correction device including a filter configured to emphasize a high band of the brightness signal. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
