Image input system

Abstract

To provide an image input system which enables to obtain a high-precision composite image at high speed with an easy operation from divisional images taken from an object, through calculating positional relations among the divisional images at high speed and with high precision by making use of the characteristic of the image input operation; an image acquisition indicating means ( ) generates an image acquisition indication referring to a present position of a camera ( ) detected by a position detector ( ). Each of the divisional images is acquired according to the image acquisition indication automatically at fixed intervals so as to have an overlap with another of the divisional images and stored together with attribution information and acquisition condition of the divisional image. A positioning parameter determining means ( ) selects a most appropriate correction parameter of the position of the divided image to be synthesized in the composite image according to candidate parameter set nominated according to the acquisition condition.
