摘要： Disclosed is an image synthesis device including an area determining unit 3 for selecting a vehicle-mounted camera 1 used for generation of a bird's-eye view image viewed from an arbitrary point of view from vehicle-mounted cameras 1a to 1d mounted at different positions, and for determining an area corresponding to the bird's-eye view image in an image captured by the vehicle-mounted camera 1, and an input video signal control unit 4 for receiving image data about the area determined by the area determining unit 3, the image data being included in image data showing the image captured by the vehicle-mounted camera 1, to store the image data in an input frame buffer 5, in which an image processing device 6 generates a bird's-eye view image from the image data stored in the input frame buffer 5.

摘要： A vector graphics data management unit 24 has a management table 25 holding pointers and priority ranks of caches to a cache unit 23. The management table 25 also holds a pointer whose priority rank is lower than those of pointers pointing to data cached by the cache unit 23. When receiving a drawing command, the vector graphics data management unit 24 carries out determination of whether a pointer included in the drawing command exists in the management table 25 and management of the management table 25 on the basis of a predetermined insertion rank when the pointer does not exist in the management table.

摘要： A window combining device includes a window control unit for adding one window number to pixels on a window-by-window basis, a two-dimensional drawing engine for combining a drawn window including the pixels to which the window number is added by the window control unit into a display window, and a display control unit for displaying the display window into which the drawn window is combined by the two-dimensional drawing engine. When an update occurs in one of a plurality of drawn windows which construct the display window, the two-dimensional drawing engine computes an original background color from a pixel to which a blend flag showing that the pixel is a target for an antialiasing process is added, the pixel being included in pixels of the window for which the update occurs, and carries out the antialiasing process and recombines pixels into the display window.
