To provide an omnidirectional vision system that can sufficiently trace a moving picture even when number of pixels is increased through high- speed image conversion processing and can be downsized.

The omnidirectional vision system is provided with an optical system 1 that can obtain a video image with a vision area around 360 degrees and convert the central projection, an image pickup means 2 that converts an optical image obtained through the optical system 1 into image data, an image recording means 3 that records an output from the image pickup means 2, an image conversion means 4 that receives image data into a panorama image or a perspective image or the like, a display means 5, and a display control means 6. The image control means 4 consists of a hardware unit including an arithmetic logic circuit for panorama conversion and perspective conversion and can conduct image conversion processing at a higher speed than that of a conventional technology where software conducts the processing and then the omnidirectional vision system can be downsized.
