Abstract:
1. A pose detection method implemented in a video game using an input image supplied by a camera for detecting a pose of a player, the method comprising the steps of: calculating a left side frame difference background difference a left side image corresponding to a left side region of an image captured by the camera which captured image includes a player image representing the pose of the player and a right side frame difference or background difference of a right side image corresponding to a right side region of the captured image; calculating a left side center position of the left side frame difference or background difference and a right side center position of the right side frame difference or background difference; calculating a positional difference between the left side center position and the right side center position with respect to up and down directions; calculating an average position value of the left side center position and the right side center position with respect to up and down directions; and generating operations information corresponding to the pose of the player based on the calculated positional difference and calculated average position values, converting a value based on the calculated positional difference and the calculated average position value into an analog stick signal, calculating an additional region background difference of an additional region other than the left side region and the right side region within the captured image; and generating the operations information corresponding to the pose of the player based on whether the additional region background difference is substantial upon determining that the left side background difference and the right side background difference are insubstantial.
