PURPOSE:To easily detect an infinite far point in a short period by extracting the image data of the object group of two systems, calculating the center of gravity of the object which is located at the farthest place from the infinite far point in respective two systems and determining the infinite far point based on the calculating result. CONSTITUTION:The picture signal obtained by a television camera 1 is stored through an A/D converter 2 and a binary circuit 3 to a memory 4. The image data of the object group of two systems arranged so as to go to the infinite far point in the picture obtained by the television camera 1 are extracted from the memory 4. A center of gravity calculating means 5 calculates the center of gravity of the object, which is located at the farthest place from the infinite far point in two respective systems, based on the image data. An infinite far point determining means 6 generates plural straight lines to extend in other object direction of the system, to which the object having the center of gravity belongs, from the center of gravity obtained by the center of gravity calculating means 5, and the infinite far point is determined based on the straight line to cross mostly with the object in the straight line.
