Abstract
An ITV camera picks up an image of an image pickup region including a moving object and a fixed object which serves as a reference to measure a distance. Images are fetched through the ITV camera at a first aperture which discriminates between a background and the fixed object and a second aperture which discriminates between the background and the moving object. The images thus fetched are added together and edges (outlines) of the fixed object and the moving object from the added image. A distance between the fixed object and the moving object is calculated from the extracted edges. The optimal aperture, enlargement ratio and focal lengths are automatically determined in a short period of time in accordance with the image pickup region and an optimal image is provided.
