PROBLEM TO BE SOLVED: To accelerate image formation processing for distortion correction of a fisheye lens image when a fisheye lens camera is mounted at an arbitrary installation angle, to accurately detect and extract a moving image of a person or the like, and to highly accurately display the image on a monitor television or the like, regarding a fisheye lens camera apparatus, image distortion correcting method thereof, and image extracting method. SOLUTION: Images photographed by a fisheye lens 1-1 and a CCD imaging apparatus 1-2 are stored in a video memory 1-3 and an image correction processing unit 1-4 is configured to operate coordinate transform for correcting the installation angle of the fisheye lens camera in combination with coordinate transform for correcting the distortion of a fisheye lens image, and to perform high-speed mapping transform on the fisheye lens image of equal-area projection. Furthermore, weighting is performed in accordance with the area within the fisheye lens image, a feature amount of the person or the like is extracted and a display area is extracted.
