<P>PROBLEM TO BE SOLVED: To provide a radar image generation device capable of suppressing loads of a GPU when generating a radar image. <P>SOLUTION: The radar image generation device includes an interface part, a position data generation processing part, a texture conversion processing part, an apex buffer, a texture buffer, a radar image generation part, an output part, and background texture updating part. The position data generation processing part generates position data on the basis of digital signals received in the interface part. The texture conversion processing part converts target information included in the digital signals to texture data. The radar image generation part prepares first display screen data from the position data and the texture data stored in the apex buffer and the texture buffer, respectively, in a first cycle, prepares second display screen data from stipulated position data and background texture data, and generates radar image data from them. The background texture updating part updates the background texture data in a second cycle. <P>COPYRIGHT: (C)2013,JPO&INPIT |
