摘要： The present invention generally relates to the field of an image system using a pantoscopic lens as an input video image source. In particular, all of the image process steps are in SOC (System on A Chip) without PC. The present invention provides the entire-view video image process method comprising the steps of: (1) start; (2) inputting and processing the information for transforming a pantoscopic image based on hemisphere coordinate to another pantoscopic image based on cylindrical coordinate, and generating a cylindrical projection image; (3) inputting and confirming the information applied to generate a plurality of perspective object images based on cylindrical coordinate, and then generating the plurality of perspective object images; (4) merging the cylindrical projection image and the plurality of perspective object images to become an output video image, and determining the output video image; (5) end.

摘要： A method is disclosed for transforming a wide-angle video image in to a Perspective view or a Cylindrical video image with reduced distortion. The method for providing an output image in either a Cylindrical mode or a Perspective mode, and comprising steps of: (1) acquiring a wide-angle image, which is a circular projection image, which format selected from the group of full circle, rounded rectangle, and full projection; (2) using a degree of view (DOV) and a radius of a projected circular region of the wide-angle image to select an image in one of Azimuthal modes; (3) specifying a horizontal field of view range (HFOVR) and a vertical field of view range (VFOVR) as a source projection image region, which is in Azimuthal mode; (4) converting the source projection image region in Azimuthal mode into a new source projection image region in Cylindrical mode; (5) converting the new source projection image in Cylindrical mode into another source projection image in Perspective mode; and (6) generating the output image.
