IMAGE INTEGRATION UNIT AND IMAGE INTEGRATION METHOD

An image integration unit includes: an imaging section which is installed in a moving body and which images a plurality of time-series images at different times; a three-dimensional image information calculating section which calculates three-dimensional image information in each of the time-series images based on the time-series images imaged by the imaging section; a stationary body area extracting section which extracts stationary body areas in each of the time-series images based on the three-dimensional image information; and an integrating section which calculates the corresponding stationary body areas between the time-series images from each of the stationary body areas extracted in each of the time-series images, and matches the corresponding stationary body areas to integrate the time-series images.
