DISPLAY PROCESSING DEVICE, DISPLAY PROCESSING METHOD, AND DISPLAY PROCESSING PROGRAM

摘要

Even when display data including tone values such as gray scale is drawn at high speed, quick drawing is achieved without inviting degradation of the visual effect. When high-speed drawing for display scrolling is needed, a drawing switch signal is inputted at step S110, and high-speed drawing display data is outputted in response to the signal to a display (17) at step S130 to display an image or a text. At step S120, high-speed drawing display data used to display each pixel of the text or image by using binarized tone values obtained by binarizing the corresponding tone values created, and the text or image is displayed in display (17) by using the high-speed drawing display data. In such a way, when high-speed drawing is needed, data including binarized tone values are used, thereby performing quick processing without increasing the loads on the CPU and the graphic controller.
