Abstract

A target image detection device for detecting a target image from an original image has an acquiring section for acquiring the original image, a determining section for determining a detection condition different from a detection condition of a previous time of a plurality of detection conditions for detecting the target image, a detecting section for detecting the target image with the detection condition determined by the determining section with respect to the original image acquired by the acquiring section, and an output section for outputting a detection result detected by the detecting section.

Claims

1. A target image detection device for detecting a target image from an original image;

the target image detection device comprising;

an acquiring section for acquiring the original image;

a determining section for determining a detection condition different from a detection condition of a previous time of a plurality of detection conditions for detecting the target image;

a detecting section for detecting the target image with the detection condition determined by the determining section with respect to the original image acquired by the acquiring section; and

an output section for outputting a detection result detected by the detecting section.

2. The target image detection device according to claim 1, further comprising:

a result history storage section for storing a history of the detection result detected by the detecting section;

wherein

the determining section further determines the detection condition based on the history of the detection result in the result history storage section.

3. The target image detection device according to claim 1, wherein

the determining section sequentially determines the detection condition from the plurality of detection conditions for detecting the target image.

4. The target image detection device according to claim 1, wherein

the acquiring section acquires a plurality of still images contained in a moving image as the original image,

a tracking section for tracking, with respect to the original image of a certain time point acquired by the acquiring section, the target image detected by the detecting section in the original image of a time point after the time point is further arranged;

and

the output section further outputs a tracking result tracked by the tracking section.

5. The target image detection device according to claim 4, further comprising:

a correcting section for correcting the tracking result tracked by the tracking section based on the detection result detected by the detecting section;

wherein

the output section outputs the tracking result corrected by the correcting section instead of the tracking result tracked by the tracking section.

6. An electronic apparatus comprising the target image detection device according to claim 1.

7. The electronic apparatus according to claim 6, further comprising:

a display unit for displaying information; and

an image synthesizing unit for synthesizing an image indicating the detection result detected by the target image detection device to the original image, and displaying on the display unit.

8. A computer readable medium storing a control program for operating the target image detection device according to claim 1, the program causing a computer to function as each section.

9. (canceled)

10. A method for controlling a target image detection device for detecting a target image from an original image;

the method comprising the steps of;

acquiring the original image;

determining a detection condition different from a detection condition of a previous time of a plurality of detection conditions for detecting the target image;

detecting the target image with the detection condition determined in the determining step with respect to the original image acquired in the acquiring step; and

outputting a detection result detected in the detection step.

11. A computer readable medium storing a program for causing a computer to perform the method of claim 10.
