<p>PURPOSE:To decrease the burden of an operator and to improve usability by providing a means to detect the tilt of display information, and correcting the tilt of the display information based on a detection result. CONSTITUTION:An image processor 1 reads a picture for one page from an optical disk device 2, expands compressed data to the dot data corresponding to a scanning line density, and stores the data into a picture memory 3. At such a time, by detecting the left edge of the picture, the tilt of the picture is detected, when the tilt is a certain value or more, the tilt is corrected, and corrected data are written to a position correcting memory 4. At such a time, the upper left edge of the picture is detected, and it is used for the position correction. The tilt detection and correction are executed by the processor 1, further the display information is transferred to a display memory 5, and displayed on the same position of a display CRT. Thus, the burden of the operator is decreased, and the usability can be improved.</p> |
