Electronic camera and photographing composition determination apparatus mountable on electronic camera
First Claim
1. A photographing composition determination apparatus for an electronic camera, comprising:
- an image sensor having a plurality of light receiving elements and disposed in an area shape so as to correspond to a photographing scene;
a light receiving lens which introduces an object image to the image sensor;
an A/D converter which converts analog signals output from the respective light receiving elements of the image sensor into digital data; and
a controller which detects the distribution of luminance and the distribution of distances in the photographing scene based on the digital data output from the A/D converter and determines a photographing composition according to the distribution of the luminance and the distribution of the distances, the controller determining whether or not the photographing composition is laterally long, based on the distribution of the luminance, and determining an upper part of a vertically long composition according to the distribution of the distances, when determining that the photographing composition is not laterally long.

Abstract
A photographing composition determination apparatus of an electronic camera includes an area sensor having a plurality of light receiving elements and disposed in an area shape so as to correspond to a photographing scene. A light receiving lens introduces an object image to the area sensor. An A/D converter converts analog signals output from the respective light receiving elements of the area sensor into digital data. A CPU detects the distribution of luminance and the distribution of distances in the photographing scene based on the digital data output from the A/D converter and determines a photographing composition according to the distribution of the luminance and the distribution of the distances.

4. A photographing composition determination method, comprising:
-
accepting digital image data; determining a distribution of luminance in a photographing scene based on the accepted digital image data; determining a distribution of distances in the photographing scene based on the accepted digital image data; and determining an orientation of a photographing composition, including determining whether or not the photographing composition is laterally long, based on the distribution of the luminance, and if it was determined that the photographing composition is not laterally long, then determining an upper part of a vertically long composition according to the distribution of the distances.
