Embodiment 1

[0029] figure 1 It is a diagram showing the configuration of the rendering display device in Embodiment 1 of the present invention. exist figure 1 Among them, still image data 101, moving image data 102, and character string image data 103 are respectively expanded and recorded in non-display memories 301, 302, and 303 by corresponding data expansion units 201, 202, and 203, respectively. The data expansion units 201 , 202 , and 203 also have a function of changing the update information of the image data recorded in the update information recording units 401 , 402 , and 403 , respectively. In the layout information recording parts 501, 502, and 503, the display areas on the monitor corresponding to the images of the still image data 101, the moving image data 102, and the character string image data 103, respectively, or when each image overlaps are recorded.

Abstract

There is provided a rendering display device which can simply performing image superposition without having complicated mask data when displaying a plurality of images superposed on a monitor. When layout information (501, 502, 503) specifies an image to be displayed on a front surface than an image corresponding to at least one image data recorded in non-display memories (301, 302, 303) and updated, a transfer control unit (2) transfers the updated image data and the image data on the image specified to be displayed on the front surface to an entire non-display memory (3).

Description

[0001] technology area [0002] The present invention relates to a rendering display device for displaying image data on a monitor. Background technique [0003] In conventional rendering and display devices, when multiple images are superimposed and displayed on a monitor, if there are frequently updated images such as moving images, complex processing such as mask data and rectangle management must be used to render the image data and display them on the on the monitor. In addition, there is an image display system that efficiently synthesizes data of different frame rates in only one frame memory and displays them on a monitor. (For example, refer to Patent Document 1) [0004] [Patent Document 1] [0005] Japanese Patent Laying-Open No. Hei 7-104722 Gazette (Fig. 1) Contents of the invention [0006] The image display system disclosed in Patent Document 1 has a problem that it cannot manage the order of superimposition, update status, and the like. It is an object o...
