Cards image processing in front of the direction, as well as a process for producing a view from a bird's eye view of a two-dimensional map image

摘要

A cards are described image processing method and an associated device for generating a view from a bird's eye view of a two-dimensional map image in real time. In this case, a map image with a larger region, as a display area for display on a display device shown or is produced and stored. If a picture barrel display is instructed, a portion of the two-dimensional map and read out sequentially a display processing process is carried out sequentially. A view from the bird's-eye perspective is obtained by processing of the two-dimensional map. A display processing process is applied to the view of a bird's eye view. Since the view of a bird's eye view to simple processing on the two-dimensional map image is generated, the image of the bird's-eye perspective view of be produced at high speed without jerking or smooth and can be represented in the scroll.
