<p>PURPOSE:To quickly and easily input a coordinate position, moving a cursor on a screen, by detecting the movement of the head of an operator, etc., for example, in a coordinate input device for a computer, etc. CONSTITUTION:An image pickup part 4 picks up the image of the movement of the head of the operator, etc., and a feature point coordinate calculation processing part 5 calculates the feature point coordinate of a moving area from a picked-up image signal, and a feature point horizontal coordinate position mirror image inversion processing part 6 performs the mirror image inversion of the coordinate position obtained from calculated feature point coordinates only in the horizontal direction, and decides the position of the cursor on the screen of a display device 1. In this way, it is possible to move the display of the cursor fitting in the movement of the head, etc., and to input a desired coordinate position.</p> |
