20120026179 | IMAGE PROCESSING DIVISION - In an image processing device, an image data generation unit generates image data of an object to be displayed on a display device in each vertical scan period. A memory management unit manages a working memory for storing the image data generated by the image data generation unit. The memory management unit selects a storage region of the working memory for storing image data when the same is generated and stores the generated image data in the selected storage region, and releases another storage region which stores image data that has been used for display on the display device, thereby allowing said another storage to store new image data. A drawing unit reads image data required to draw one line on the display device in each horizontal scan period from the working memory through the memory management unit, then generates the image data of one line based on the read image data, and stores the generated image data of one line in a line buffer. A controller sequentially instructs the image data generation unit to generate image data of each object before image data of each object is displayed on the display device in each vertical scan period. | 02-02-2012 |
