<p>PROBLEM TO BE SOLVED: To provide a technique for more accurately obtaining a three-dimensional coordinate position of an operation object.SOLUTION: An indicated position by an operation object is specified on the basis of a captured image which is captured by a capturing unit and in which distance information between the capturing unit and the operation object is reflected. A direction of the operation object is specified on the basis of the captured image. On the basis of image information of a portion corresponding to the indicated position in the captured image and the direction of the operation object, it is determined that a distance between the operation object and a target surface is smaller than a predetermined value.</p> |
