Patent ID: 11317114

Abstract:
A padding processing section replaces, by using an input image which is a two-dimensional image in which plural fisheye images configuring a predetermined azimuth range are provided side by side, an image to be used in a prediction process outside a valid region of a fisheye image with an image at a corresponding position in a valid region of another fisheye image based on continuity of the plural fisheye images to reduce prediction errors. The padding processing section calculates the position in the valid region of the other fisheye image corresponding to the position outside the valid region based on fisheye image information indicative, for each fisheye image, of a center position, a fisheye radius, or a state of reversal or rotation of the fisheye image in the two-dimensional image. A reversible encoding section includes the fisheye image information into an encoded stream of the two-dimensional image.
