  • Publication number: 20230206386
    Abstract: The disclosed technique facilitates confirmation of a perspective projection image generated from a partial image region corresponding to a predetermined angle of view of a wide-angle image. First, an image obtainment unit obtains an ultrawide-angle image. A region information obtainment unit obtains an optical axis direction and an angle of view of a virtual camera for defining an image for confirmation set for the ultrawide-angle image and obtains predetermined viewing angle information. An image conversion unit converts the obtained ultrawide-angle image into the perspective projection image as the image for confirmation based on the obtained optical axis direction and angle of view of the virtual camera. A region information drawing unit calculates a visual field region based on the viewing angle information on the angle of view of the virtual camera and superimposes and draws a rectangle indicating the calculated visual field region on the perspective projection image.
