Abstract
Abstract In forming a panoramic picture image by compositing picture images dividedly imaged, the invention corrects deviations of images of an object at overlap regions caused by a difference in fields of view of imaging means or movement of an object to be imaged in which a picture image forming apparatus includes a picture image inputting device, a frame memory for storing divided picture images inputted from the picture image inputting device, a picture image position calculating unit for calculating positions of compositing the divided picture images, a picture image parallax sampling and processing unit for sampling parallax information among picture images from picture images including parallaxes in the overlap regions among contiguous divided picture images, an intermediate picture image forming and processing unit for forming a plurality of intermediate picture images from the picture images including the parallaxes and a picture image composition and processing unit for compositing a panoramic picture image from the divided picture images where the deviations of images in the overlap regions are corrected by the picture image parallax sampling and processing unit and the panoramic picture images are composited performing an interpolation by the intermediate picture images formed by the intermediate picture image forming and processing unit.
