Abstract

An accurate determination of an operation is possible. Data photographed by a video camera is read by an image reading unit, and an image of an operator is extracted from the data by an image extracting unit. As a result of such preparation, a virtual operation screen and an operation region are created based upon the extracted image of the operator. In a case of an adult operator, an operation region can be created in consideration with a length (position of sight line) or a length of an arm, and in a case of a child, since a length is lower and a length of an arm is shorter, an operation region can be set to match it.

Claims

1. An image recognition apparatus comprising:

a first component configured to create an operation region between a three-dimensional photography device and an operator based on a position of the operator taken by the three-dimensional photography device;

a second component configured to detect a change of the position of at least a part of the operator in the operation region based on the position of at least a part of the operator taken by the three-dimensional photography device; and

a third component configured to output, based on the detected change of the position of the at least a part of the operator in the operation region, a signal to change a mark displayed in a display device, the display device being visually recognized by the operator,

wherein a function associated with the mark is selected when the part of the operator moves a predetermined amount toward the function.

2. The image recognition apparatus according to claim 1 wherein the third component determines an operation by the operator based on the detected change of the position of the at least a part of the operator in the operation region to output a signal to change a mark displayed in a display device, the display device being visually recognized by the operator based on the result of the determination.

3. The image recognition apparatus according to claim 1 wherein the first component creates an operation region at a timing when the body of the operator has stopped for a given time.

4. An image recognition apparatus comprising:

a first component configured to create an operation region between a three-dimensional photography device and an operator based on a position of the operator taken by the three-dimensional photography device;

a second component configured to detect a change of the position of at least a part of the operator in the operation region based on the position of the at least a part of the operator taken by the three-dimensional photography device; and

a third component configured to output, based on the detected change of the position of the at least a part of the operator in the operation region, a signal to change a mark displayed in a display device, the display device being visually recognized by the operator,

wherein a function associated with the mark is selected when the part of the operator enters into a predetermined area corresponding to the function.

5. An image recognition apparatus comprising:

a first component configured to create an operation region between a three-dimensional photography device and an operator based on a position of the operator taken by the three-dimensional photography device;

a second component configured to detect a change of the position of at least a part of the operator in the operation region based on the position of the at least a part of the operator taken by the three-dimensional photography device; and

a third component configured to output, based on the detected change of the position of the at least a part of the operator in the operation region, a signal to change a mark displayed in a display device, the display device being visually recognized by the operator,

wherein a function associated with the mark is selected when the mark becomes a particular mark.
