Operation input apparatus, operation input method, and program

An operation input method comprising the steps of:

• receiving image data obtained by image capturing and detecting a certain body portion of a photographic subject in an image corresponding to the image data;
• determining a certain state corresponding to a priority-level setting condition, when a plurality of body portions are detected, for each body portion;
• setting priority levels to the individual body portions in accordance with results of the determination;
• determining whether the detected body portions performed a predetermined motion corresponding to a certain operation in accordance with determination allowance degrees of the body portions serving as determination subjects which are set in accordance with the priority levels;
• and
• controlling the operation input apparatus so that the operation input apparatus performs a predetermined operation in accordance with the determination that the certain motion corresponding to the certain operation has been performed.

A program which makes an operation input apparatus execute the steps of:

• receiving image data obtained by image capturing and detecting a certain body portion of a photographic subject in an image corresponding to the image data;
• determining a certain state corresponding to a priority-level setting condition, when a plurality of body portions are detected, for each body portion;
• setting priority levels to the individual body portions in accordance with results of the determination;
• determining whether the detected body portions performed a predetermined motion corresponding to a certain operation in accordance with determination allowance degrees of the body portions serving as determination subjects which are set in accordance with the priority levels;
• and
• controlling the operation input apparatus so that the operation input apparatus performs a predetermined operation in accordance with the determination that the certain motion corresponding to the certain operation has been performed.

An operation input apparatus comprising:

• a body portion detection unit configured to receive image data obtained by image capturing and detect a certain body portion of a photographic subject in an image corresponding to the image data;
• a state determination unit configured to determine a certain state corresponding to a priority-level setting condition, when a plurality of body portions are detected using the body portion detection unit, for each body portion;
• a priority-level setting unit configured to set priority levels to the individual body portions in accordance with results of the determination performed by the state determination unit;
• an operation determination unit configured to determine whether the body portions detected by the body portion detection unit performed a predetermined motion corresponding to a certain operation in accordance with determination allowance degrees of the body portions serving as determination subjects which are set in accordance with the priority levels;
• and
• a control unit configured to control the operation input apparatus so that the operation input apparatus performs a predetermined operation in accordance with the determination that the certain motion corresponding to the certain operation has been performed which is made by the operation determination unit.
