<p><P>PROBLEM TO BE SOLVED: To provide a radar video display device for sharply reducing the load of CPU processing by performing the extinction processing of video data necessary in term of the characteristics of radar video and processing for preferentially plotting a point with high luminance by the GPU processing. <P>SOLUTION: The radar video display device is configured to perform processing to transmit data for an azimuth received from a CPU from a main memory to a texture memory, and to input the plotting vertex information of coordinates, luminance, and update time from the texture memory in the GPU, and to perform extinction calculation to the luminance with a difference between the update time and the current time, and to integrate the gradation information of the luminance of the data for one range resolution to which the extinction calculation has been performed as the z of a coordinate axis, and to convert the three-dimensional data into two-dimensional image data by performing rendering processing from the three-dimensional coordinate value and luminance of the plotting vertex information. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
