<p>PROBLEM TO BE SOLVED: To read out image data from a process displaying memory in which the image data are stored in accordance with a predetermined displaying mode to display the image at an arbitrary angle in radar image displaying. SOLUTION: Data are simultaneously written in every predetermined two-dimensional area by one cycle of memory access action, and radar echo data is written into the processing displaying memory where readable radar echo data is stored or this memory in the predetermined displaying mode and a cache, which reads out or reads out to rewrite and then processes every predetermined unit of two-dimensional square when the radar echo data is read out from this memory at a predetermined angle, is placed. Thereby the image data is read out from the process displaying memory by raster scan display scanning at an arbitrary angle and a displaying image is rotated by an arbitrary angle and directly displayed on a display device.</p> |
