INFORMATION PROCESSOR

PURPOSE:To improve the work efficiency by measuring a distance between the display screen of a display and a worker, calculating the magnification corresponding to its distance, processing an image, based on its magnification, and displaying the image enlarged by said calculated magnification on the display. CONSTITUTION:A range finder 2 is provided on the upper part of a display device 9, a distance DM between a display screen and a worker 10 is measured at every prescribed period, and as a result of its measurement, the distance DM is inputted to a CPU together with an interrupting signal. When the distance DM is smaller than a reference value DR set in advance, the CPU calculates magnification Z of a graphic corresponding to the distance DM, outputs it to a processing circuit, and the processing circuit brings image data of a prescribed range to enlargement processing by magnification Z centering around a position designated by a cursor and stores it, and displays it on a display part through a driving circuit. Also, in the case of DM >= DR, it is maintained in one fold. In such a way, the work efficiency can be improved by decreasing an enlarging or reducing operation of the graphic by an input device, and decreasing a work miss.
