<P>PROBLEM TO BE SOLVED: To provide a lighting dot ratio calculation device capable of coping with scroll display at one-dot intervals and a drawing device using the lighting dot ratio calculation device. <P>SOLUTION: A processing section 16 of the drawing device includes: a dot pattern storage section 61 for storing a dot pattern showing dot arrays of an image to be displayed on a display device; a scan area setting section 62 for setting a scan area smaller than the dot pattern; a lighting ratio calculation area setting section 63 for setting a plurality of lighting ratio calculation areas at positions shifted at one-dot intervals from a scan initial position to a scan end position by applying the scan area by shifting the scan area at one-dot intervals along a scan route fixed in advance from the scan initial position to the scan end position on the dot pattern; and a lighting dot ratio calculation section 64 for calculating the lighting dot ratio in each of the lighting ratio calculation areas as to the lighting ratio calculation area. <P>COPYRIGHT: (C)2013,JPO&INPIT |
