Abstract

A non-transitory storage medium encoded with a computer readable image processing program is provided. The image processing program causes a computer to perform functionality including obtaining an infrared image of a subject and determining a position of the subject included in the infrared image based on brightness and a size of a prescribed region of the subject within the infrared image.

Claims

1. A non-transitory storage medium encoded with a computer readable image processing program executed by a computer, the image processing program causing the computer to perform functionality comprising:

obtaining an infrared image of a subject; and

determining a position of the subject included in the infrared image based on brightness and a size of a prescribed region of the subject within the infrared image.

2. The non-transitory storage medium according to claim 1, wherein

the step of determining the position includes determining a relative position of the subject with a reference position.

3. The non-transitory storage medium according to claim 2, wherein

the step of determining the position includes determining the reference position based on an infrared image corresponding to the subject positioned in a reference state.

4. The non-transitory storage medium according to claim 1, wherein

the step of determining the position includes determining a position of the subject based on the brightness of the prescribed region when the size of the prescribed region satisfies a prescribed condition.

5. The non-transitory storage medium according to claim 1, wherein

the step of determining the position includes determining a depth position of the subject in a direction of image pick-up by an image pick-up portion which obtains the infrared image, based on the brightness and the size of the prescribed region.

6. The non-transitory storage medium according to claim 5, wherein

the step of determining the position includes determining the depth position and determining a position on a surface orthogonal to the direction of image pick-up of the subject based on a position of the prescribed region within the infrared image.

7. The non-transitory storage medium according to claim 1, wherein

the step of determining the position includes specifying a region of the subject from the infrared image and specifying the prescribed region in accordance with the specified region.

8. The non-transitory storage medium according to claim 7, wherein

the step of specifying the region includes specifying the prescribed region of the subject based on at least a part of a shape which the subject intrinsically has.

9. The non-transitory storage medium according to claim 1, wherein

the step of determining the position includes determining a position of the subject when the brightness of the prescribed region and the size of the prescribed region satisfy prescribed relation.

10. The non-transitory storage medium according to claim 9, wherein

the step of determining the position includes determining the position of the subject when change over time in brightness of the prescribed region and change over time in size of the prescribed region maintain the prescribed relation.

11. The non-transitory storage medium according to claim 9, wherein

the step of determining the position includes determining the position of the subject when magnitude of change over time in brightness of the prescribed region and magnitude of change over time in size of the prescribed region maintain the prescribed relation.

12. The non-transitory storage medium according to claim 1, wherein

the step of determining the position includes outputting change over time in position of the subject.

13. The non-transitory storage medium according to claim 1, wherein

the step of obtaining the image includes obtaining an infrared image which is picked up during emission of infrared rays to the subject.

14. An information processing system, comprising:

an image pick-up portion configured to pick up an image of infrared light from a subject; and

a processing portion configured to determine a position of the subject included in the infrared image based on brightness and a size of a prescribed region of the subject within the infrared image obtained as a result of image pick-up by the image pick-up portion.

15. An information processing apparatus, comprising:

an image obtaining module configured to obtain an infrared image of a subject; and

a position determination module configured to determine a position of the subject included in the infrared image based on brightness and a size of a prescribed region of the subject within the infrared image.

16. An information processing method, comprising:

obtaining an infrared image of a subject; and

determining a position of the subject included in the infrared image based on brightness and a size of a prescribed region of the subject within the infrared image.
