Abstract

An object displayed in a picture can be designated by the operator, without use of any additional device for inputting data other than position data. Position data of a pointer for designating any desired position in a picture are inputted by a pointer position input section (1). On the basis of the input data, a change of the pointer position relative to a specific region (13) set in relation to an object (12) in the picture is detected by a pointer region pass detecting section (2). On the basis of the output of the pointer region pass detecting section (2), the pointer positions obtained by the pointer position inputting section (1) are accumulated by a pointer position accumulating section (3). Further, the pointer locus data obtained by the pointer position accumulating section (3) are recognized by a gesture recognizing section (4) to detect a significant movement (a specific input operation) of the pointer in a specific region. The detected significant movement of the pointer is applied to a processing section (5) to receive the significant input operation corresponding to the significant movement of the pointer other than the position data.
