Abstract
A camera includes a CPU. The CPU individually detects a ratio of an object which exceeds a threshold value in a moving amount to a center area of an object scene and a ratio of an object which exceeds the threshold value in the moving amount to a peripheral area of the object scene. If differences between the respective detected ratios are large, the CPU sets a photographing mode to a sports mode. When a shutter button is operated, the object scene is photographed in accordance with a set photographing mode.
Claims19
A camera performing photographing in accordance with a photographing mode corresponding to an object scene when a photographing operation is performed, comprising:
- a first ratio detector for detecting a first ratio of an object exceeding a first threshold value in a moving amount to a center area of said object scene;
- a second ratio detector for detecting a second ratio of an object exceeding a second threshold value in the moving amount to a peripheral area of said object scene;
- and
- a determiner for determining the photographing mode on the basis of the first ratio and the second ratio.
A photographing mode determining method of a camera which performs photographing when the photographing operation is performed, comprising steps of:
- (a) detecting a first ratio of an object exceeding a first threshold value in a moving amount to a center area of an object scene;
- (b) detecting a second ratio of an object exceeding a second threshold value in the moving amount to a peripheral area of said object scene;
- and
- (c) determining the photographing mode on the basis of the first ratio and the second ratio.
A camera performing photographing in accordance with a photographing mode corresponding to an object scene, comprising:
- a first detector for detecting an average luminance of said object scene;
- a second detector for detecting a ratio of a high luminance area to said object scene;
- and
- a determiner for determining the photographing mode on the basis of the average luminance and the ratio.
A photographing mode determining method of a camera which photographs an object scene, comprising steps of:
- (a) detecting an average luminance of said object scene;
- (b) detecting a ratio of a high luminance area to said object scene;
- and
- (c) determining the photographing mode on the basis of the average luminance and the ratio.
A camera performing photographing in a photographing mode corresponding to an object scene, comprising:
- a ratio detector for detecting a ratio of a high luminance evening scene color area to a defined area formed in a cross shape in said object scene;
- a luminance difference detector for detecting a luminance difference between periphery areas opposed with each other in said object scene;
- and
- a determiner for determining the photographing mode on the basis of the ratio and the luminance difference.
A photographing mode determining method of a camera which photographs an object scene, comprising steps of:
- (a) detecting a ratio of a high luminance evening scene color area to a defined area formed in a cross shape in said object scene;
- (b) detecting a luminance difference between periphery areas opposed with each other in said object scene;
- and
- (c) determining the photographing mode on the basis of the ratio and the luminance difference.
A camera for performing photographing in accordance with a photographing mode corresponding to an object scene, comprising:
- a first measure for measuring a distance to a main object existing in said object scene;
- a specifier for specifying a face area to be occupied by a face of a person from said object scene on the basis of the distance measured by said first measure;
- a detector for detecting a skin color area of said object scene;
- and
- a determiner for determining the photographing mode on the basis of a relationship between said face area and said skin color area.
A photographing mode determining method of a camera which photographs an object scene, comprising steps of:
- (a) determining a distance to a main object existing in said object scene;
- (b) specifying a face area to be occupied by a face of a person from said object scene on the basis of a distance measured in said step (a);
- (c) detecting a skin color area of said object scene;
- and
- (d) determining the photographing mode on the basis of a relationship between said face area and said skin color area.
