Abstract

In correspondence with each face of a rectangular parallelepiped obtained when the inside of the rectangular parallelepiped is shot, a monitor screen is split into a plurality of sub-screen areas. An image shot by a vehicle-mounted camera is processed and the processed image is split correspondingly to the sub-screen areas. Each split image is displayed in the corresponding sub-screen areas. This allows intuitive understanding of the direction of an image displayed in a sub-screen thereby providing the driver with an image free from a sense of incongruity.

Claims

1. A driving assistance display apparatus comprising image processing unit for splitting a monitor screen into a plurality of sub-screens in correspondence with each inner face of a polyhedron obtained when the inside of the polyhedron is shot, performing image processing on an image from a vehicle-mounted camera as well as splitting the processed image in correspondence with the sub-screen areas, and displaying the split images in the corresponding sub-screen areas.

2. The driving assistance display apparatus as claimed in claim 1, wherein the split at least one of images corresponding to at least one of the inner faces of the polyhedron is not displayed on the monitor screen.

3. The driving assistance display apparatus as claimed in claim 1, wherein the sub-screen areas adjacent to each other are displayed apart on the monitor screen.

4. The driving assistance display apparatus as claimed in claim 1, wherein the split images with different display magnification are displayed so as to scale the corresponding sub-screen areas to the display magnification.

5. The driving assistance display apparatus as claimed in claim 1, wherein the split images respectively displayed in the adjacent sub-screen areas are continuous at the adjacent section.

6. The driving assistance display apparatus as claimed in claim 1, wherein the split images respectively displayed in the adjacent sub-screen areas represent a single image overlapped in the adjacent section.

7. The riving assistance display apparatus as claimed in claim 1, wherein the shot image of the vehicle width range of the vehicle is displayed in the sub-screen area to display the image of the lower area in the travel direction of the vehicle among the sub-screen areas, and the shot images outside the vehicle width range are displayed in adjacent sub-screen areas.
