IMAGING APPARATUS
First Claim
1. An imaging apparatus comprising:
- an optical system which has a distortion in which a compression rate becomes larger along a direction from a center portion to an edge portion;
an imaging device which converts an optical image received via the optical system to an electrical signal and outputs image data of a first angle of view;
a feature extraction portion that extracts a feature of data which corresponds to a second angle of view among the image data, which includes an optical axis of the optical system and which is smaller than the first angle of view, and outputs as feature data;
an object detection portion which outputs a signal which indicates whether or not the object is included in the second angle of view based on the feature data;
an angle of view changing portion which selects and outputs the image data corresponding to the second angle of view when the signal input from the object detection portion indicates that the object is included, and which selects and outputs the image data corresponding to the first angle of view when the signal input from the object detection portion does not indicate that the object is included;
a distortion correction portion which corrects a distortion in the image data output from the angle of view changing portion; and
an image zoom-in/out portion which zooms in/out the image data output from the distortion correction portion in accordance with a desired image size.

Abstract
An imaging apparatus including: an optical system which has a distortion in which a compression rate becomes larger along a direction from a center portion to an edge portion; an imaging device which converts an optical image received via the optical system to an electrical signal and outputs image data of a first angle of view; a feature extraction portion that extracts a feature of data which corresponds to a second angle of view among the image data, which includes an optical axis of the optical system and which is smaller than the first angle of view, and outputs as feature data; an object detection portion which outputs a signal which indicates whether or not the object is included in the second angle of view based on the feature data; an angle of view changing portion which selects and outputs the image data corresponding to the second angle of view when the signal input from the object detection portion indicates that the object is included, and which selects and outputs the image data corresponding to the first angle of view when the signal input from the object detection portion does not indicate that the object is included; a distortion correction portion which corrects a distortion in the image data output from the angle of view changing portion; and an image zoom-in/out portion which zooms in/out the image data output from the distortion correction portion in accordance with a desired image size.

2. An imaging apparatus comprising:
-
an optical system which has a distortion characteristic in which a compression rate becomes larger along a direction from a center portion to an edge portion;
an imaging device which converts an optical image received via the optical system to an electrical signal and outputs image data of a first angle of view;
a feature extraction portion which extracts a feature of the image data and outputs as feature data;
an object detection portion which outputs a signal which indicates whether or not the object is included in the image data based on the feature data;
an object position calculation portion which calculates a position of the object in the image and generates position information when the signal input from the object detection portion indicates that the object is included;
an angle of view determination portion which, based on the position information, determines a size of a second angle of view of the image data in a manner in which the second angle of view includes an optical axis of the optical system and is smaller than the first angle of view;
an angle of view changing portion which selects and outputs the image data corresponding to the second angle of view when the signal input from the object detection portion indicates that the object is included, and which selects and outputs the image data corresponding to the first angle of view when the signal input from the object detection portion does not indicate that the object is included;
a distortion correction portion which corrects a distortion in the image data output from the angle of view changing portion; and
an image zoom-in/out portion which zooms in/out the image data output from the distortion correction portion in accordance with a desired image size. - View Dependent Claims (8)
