First Claim
Patent Images
1. 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 which detects a first ratio of movement of an object exceeding a first threshold value in a moving amount in a center area of said object scene;
a second ratio detector which detects a second ratio of movement of an object exceeding a second threshold value in the moving amount in a peripheral area of said object scene;
a determiner which determines the highest probability that the object scene is one of a plurality of object scene types based on the first ratio of movement and the second ratio of movement respectively detected by said first ratio detector and said second ratio detector; and
a selector which selects the photographing mode based on the highest probability that the object scene is one of the plurality of object scene types determined by said determiner.

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.

5. 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 movement of an object exceeding a first threshold value in a moving amount in a center area of an object scene; (b) detecting a second ratio of movement of an object exceeding a second threshold value in the moving amount in a peripheral area of said object scene; (c) determining highest probability that the object scene is one of a plurality of object scene types based on the first ratio of movement and the second ratio of movement respectively detected by said step (a) and said step (b); and (d) selecting the photographing mode based on the highest probability that the object scene is one of the plurality of object scene types determined by said step (c).

6. 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 which detects a first ratio of movement of an object exceeding a first threshold value in a moving amount in a center area of said object scene; a second ratio detector which detects a second ratio of movement of an object exceeding a second threshold value in the moving amount in a peripheral area of said object scene; a determiner which determines the highest probability that the object scene is one of a plurality of object scene types based on first ratio of movement and the second ratio of movement respectively detected by said first ratio detector and said second ratio detector; and a selector which selects the photographing mode based on the highest probability that the object scene is one of the plurality of object scene types determined by said determiner; wherein the first ratio and the second ratio correspond to a ratio of movement change between a first time period and a second time period.
