Abstract
To make it possible to accurately track a prescribed part, a low-resolution overall image is taken in from an input image, and a medium-resolution image, whose center is the head part, is extracted from it. When it is possible to extract a medium-resolution image in the middle of which is the head part, an even higher-resolution image is extracted, in the middle of which is the two-eyes part.
Claims10
An image processing device comprising:
- a first extraction means for extracting an image of a prescribed part from an input image;
- a second extraction means for extracting a portion of said image of said prescribed part extracted by said first extraction means as a higher-resolution image;
- a tracking means for tracking the image of said prescribed part so that said second extraction means can continuously extract the portion of said image of said prescribed part from the image;
- a display means for displaying the input image;
- a rendering means for rendering a virtual image that is different from the input image, said virtual image including a feature that corresponds to the portion of said image of said prescribed part;
- and
- a display control means that causes the virtual image to be displayed on the display means by superimposing the virtual image on the input image, and causes the feature that corresponds to the portion of said image of said prescribed part to change in correspondence with a change in the portion of said image of said prescribed part as it is continuously extracted.

An image processing method comprising:
- a first extraction step for extracting an image of a prescribed part from an input image;
- a second extraction step for extracting a portion of said image of said prescribed part extracted in the first extraction step as a higher-resolution image;
- a tracking step for tracking the image of said prescribed part so that in the second extraction step the portion of said image of said prescribed part can be continuously extracted from the image extracted in the first extraction step;
- a rendering step for rendering a virtual image that is different from the input image, said virtual image including a feature that corresponds to the portion of said image of said prescribed part;
- and
- a display control step that causes the virtual image to be displayed on a display by superimposing the virtual image on the input image, and causes the feature that corresponds to the portion of said image of said prescribed part to change in correspondence with a change in the portion of said image of said prescribed part as it is continuously extracted.

A distribution medium comprising a program that causes processing to be executed on an image device including:
- a first extraction step for extracting an image of a prescribed part from an input image;
- a second extraction step for extracting a portion of said image of said prescribed part extracted in the first extraction step as a higher-resolution image;
- a tracking step for tracking the image of said prescribed part so that in the second extraction step the portion of said image of said prescribed part can be continuously extracted from the image extracted in the first extraction step;
- a rendering step for rendering a virtual image that is different from the input image, said virtual image including a feature that corresponds to the portion of said image of said prescribed part;
- and
- a display control step that causes the virtual image to be displayed on a display by superimposing the virtual image on the input image, and causes the feature that corresponds to the portion of said image of said prescribed part to change in correspondence with a change in the portion of said image of said prescribed part as it is continuously extracted.
