IMAGE PROCESSING METHOD AND INPUT INTERFACE APPARATUS - For an input interface apparatus for recognizing the motion of an object, there may be cases where the brightness of the object to be captured is insufficient, and thus, a camera takes an image of the object operated by the object, a depth position detector detects the position of the object based on captured frames, an action identifying unit identifies an action of the player based on a result on the detection of the object, an input receiving unit receives the action as an instruction to an input-receiving image displayed on a display, and in response to the action, an illumination control unit raises the brightness of the image projected on the display higher than that before the action is detected.
