Abstract

Proper recognition of a position can be achieved even when a predetermined part of a player moves rapidly. An image of a player is captured by a camera unit, and from this image the head position of the player is recognized, so that the game proceeds based on the recognized result. At this time, a base position group is selected in principle from a difference between the latest and immediately preceding player images within a selection range corresponding to the previously recognized position (S207), and the selection range is changed exceptionally to reselect the base position group from the difference (S210).

Claims

1. A game device, comprising:

image capturing means for capturing player images at predetermined time intervals;

selecting means for selecting a base position group used for recognizing a predetermined part of a player from a predetermined selection range corresponding to a previously recognized position based on the player images captured by said image capturing means;

reselecting means for changing said selection range in accordance with the selected base position group to reselect the base position group used for recognizing the predetermined part of the player; and

recognized position determining means for determining a present recognized position based on the base position group selected by said selecting means or reselected by said reselecting means.

2. A game device according to claim 1, wherein

said selecting means selects the base position group used for recognizing the predetermined part of the player from the predetermined selection range surrounding the previously recognized position, and

said reselecting means shifts said selection range based on said player image.

3. A game device, comprising:

image capturing means for capturing player images at predetermined time intervals;

recognizing means for recognizing a position of a predetermined part of a player based on the player images captured by said image capturing means, and outputting the recognized position;

recognized position storing means for storing a predetermined number of recognized positions formerly output by said recognizing means;

movement amount calculating means for calculating an amount of movement for each recognized position stored by said recognized position storing means;

number changing means for changing said number based on the amount of movement for each recognized position calculated by said movement amount calculating means;

output value calculating means for calculating an output value based on said number of recognized positions stored by said recognized position storing means; and

game processing means for performing a game process based on the output value supplied by said output value calculating means.

4. A method of processing an image of a person, comprising steps of:

capturing images of a person at predetermined time intervals;

selecting a base position group used for recognizing a predetermined part of the person from a predetermined selection range corresponding to a previously recognized position based on the captured images of the person;

changing said selection range based on the selected base position group to reselect the base position group used for recognizing a predetermined part of the person; and

determining a present recognized position based on the selected or reselected base position group.

5. A program for causing a computer to execute steps of:

capturing images of a person at predetermined time intervals;

selecting a base position group used for recognizing a predetermined part of the person from a predetermined selection range corresponding to a previously recognized position based on the captured images of the person;

changing said selection range based on the selected base position group to reselect the base position group used for recognizing a predetermined part of the person; and

determining a present recognized position based on the selected or reselected base position group.

6. A method for processing images of a person, comprising steps of:

capturing the images of the person at predetermined time intervals;

recognizing a position of a predetermined part of the person based on the captured images of the person, and outputting the recognized position;

sequentially storing the recognized position in storing means;

calculating an amount of movement for each recognized position stored in said storing means;

changing the number of recognized positions stored in said storing means based on the calculated amount of movement for each recognized position; and

calculating an output value based on the recognized position stored in said storing means.

7. A program for causing a computer to execute steps of:

capturing images of a person at predetermined time intervals;

recognizing a position of a predetermined part of the person based on the captured images of the person, and outputting the recognized position;

sequentially storing the recognized position in storing means;

calculating an amount of movement for each recognized position stored in said storing means;

changing the number of recognized positions stored in said storing means based on the calculated amount of movement for each recognized position; and

calculating an output value based on the recognized position stored in said storing means.
