Abstract

A gesture recognition unit recognizes a picture of a person'"'"'s gesture photographed by an image pickup unit, and a control instruction generating unit generates at least one or more control instructions corresponding to the recognition result.

Claims

1. A control apparatus for controlling a control object on the basis of a control instruction, comprising:

image pickup means for photographing a person'"'"'s gesture;

gesture recognition means for recognizing a sort of a picture of said photographed gesture; and

control instruction generating means for generating at least one or more control instructions corresponding to the sort recognized by said gesture recognition means.

2. The control apparatus as claimed in claim 1, wherein said gesture recognition means has feature analysis means for acquiring a feature of gesture from said gesture picture photographed by said image pickup means by image analysis, whereby said gesture recognition means recognizes the sort of gesture by comparing the feature acquired by said feature analysis means with the features of a plurality of gestures having the sorts known.

3. The control apparatus as claimed in claim 2, wherein the features of gestures having the sorts known can be registered, and the gesture picture photographed by said image pickup means is analyzed by said feature analysis means to acquire the feature to be registered.

4. A control method of controlling a control object on the basis of a control instruction, comprising steps of:

photographing a person'"'"'s gesture by image pickup means;

recognizing a sort of a picture of said photographed gesture by an information processor; and

generating at least one or more control instructions corresponding to the recognized sort by said information processor.

5. The control method as claimed in claim 4, wherein said information processor acquires a feature of gesture from said gesture picture photographed by said image pickup means by image analysis, and recognizes the sort of gesture by comparing the feature acquired by feature analysis with the features of a plurality of gestures having the sorts known.

6. The control method as claimed in claim 5, wherein the features of gestures having the sorts known can be registered in said information processor, and the gesture picture photographed by said image pickup means is analyzed by said feature analysis to acquire the feature to be registered.

7. A recording medium storing a program to be executed on a control apparatus for controlling a control object on the basis of a control instruction,

wherein said program comprises:

a gesture recognition step of recognizing a sort of a gesture picture photographed by image pickup means for photographing a person'"'"'s gesture; and

control instruction generating step of generating at least one or more control instructions corresponding to the sort recognized at said gesture recognition step.

8. The recording medium as claimed in claim 7, wherein said gesture recognition step comprises a feature analysis step of acquiring a feature of gesture from said gesture picture photographed by said image pickup means by image analysis, thereby recognizing the sort of gesture by comparing the feature acquired by said feature analysis means with the features of a plurality of gestures having the sorts known.

9. The recording medium as claimed in claim 8, wherein the features of gestures having the sorts known can be registered, and the gesture picture photographed by said image pickup means is analyzed at said feature analysis step to acquire the feature to be registered.
