Image processing apparatus and method, recording medium, and program

An image processing method comprising:

• an image-taking step of taking an image of a subject with an image-taking unit;
• a first detecting step of detecting the head top of the image of the subject taken in said image-taking step;
• a first judgment step of comparing the head top detected in said first detecting step and first reference data to determine whether the detected head top coincides with the first reference data;
• a second detecting step of detecting the image size of a predetermined portion of the image of the subject;
• a second judgment step of comparing the image size detected in said second detecting step with second reference data to determine whether the detected image size coincides with the second reference data;
• and
• a control step of controlling an image-taking position of said image-taking unit on the basis of results of the determinations in said first and second judgment steps.

A recording medium having a computer-readable program recorded therein, wherein said program comprises:

• an image-taking step of taking an image of a subject with an image-taking unit;
• a first detecting step of detecting the head top of the image of the subject taken in said image-taking step;
• a first judgment step of comparing the head top detected in said first detecting step and first reference data to determine whether the detected head top coincides with the first reference data;
• a second detecting step of detecting the image size of a predetermined portion of the image of the subject;
• a second judgment step of comparing the image size detected in said second detecting step with second reference data to determine whether the detected image size coincides with the second reference data;
• and
• a control step of controlling an image-taking position of said image-taking unit on the basis of results of the determinations in said first and second judgment steps.

A program that executes steps, wherein said steps comprises:

• an image-taking step of taking an image of a subject with an image-taking unit;
• a first detecting step of detecting the head top of the image of the subject taken in said image-taking step;
• a first judgment step of comparing the head top detected in said first detecting step and first reference data to determine whether the detected head top coincides with the first reference data;
• a second detecting step of detecting the size of a predetermined portion of the image of the subject;
• a second judgment step of comparing the image size detected in said second detecting step with second reference data to determine whether the detected image size coincides with the second reference data;
• and
• a control step of controlling an image-taking position of said image-taking unit on the basis of results of the determinations in said first and second judgment steps.
