IMAGING APPARATUS
First Claim
1. An imaging apparatus comprising:
- a lens;
an imaging device that detects light focused by the lens at a plurality of detection points; and
an image processing unit that generates image data for displaying an image on a display screen having a predetermined area, on the basis of image signals detected at the detection points of the imaging device,wherein the image processing unit performs image processing to enlarge a section, which is a portion of the image captured by the imaging device, and displays the enlarged image on the display screen, andin the image processing, the enlargement ratio of a field angle varies depending on the place in the section.

Abstract
Disclosed is an imaging apparatus capable of enlarging a portion of an image captured by an imaging device of a fisheye camera and displaying the enlarged image on a display screen with little distortion. The imaging apparatus enlarges a section, which is a portion of an image captured by a fisheye camera, and displays the section on a display screen such that the enlargement ratios of points in the section are different from each other. An image processing method uses a change function that changes the enlargement ratio of a field angle depending on the place is used, and converts a portion of the captured image into a central projection image to generate a display image. The use of the change function makes it possible to generate a display image having high visibility.
