A video signal processing apparatus for processing input video signals in a pre-set manner. An operating lever 1 may be actuated in arbitrary two-dimensional directions. A two-directional position detector 2 detects coordinate data from the amount of two-dimensional movement of the operating lever. If a button switch 3 is not pressed, a control circuit 4 derives the two-dimensional information for specifying a position on the video signal from the coordinate data and outputs the resulting two-dimensional information. If the button switch 3 is not pressed, the control circuit 4 derives the one-dimensional information other than the two-dimensional information from the coordinate data and outputs the resulting one-dimensional data. A picture processing unit 7 processes the input video signal in a pre-set manner based upon the two-dimensional information or the one-dimensional information from the control circuit 4. The video processing apparatus may be improved in operability because the two-dimensional information and the one-dimensional information may be produced by a simplified construction. |
