Patent ID: 8294824

Claim:
A video compositing method comprising: preparing a background-side image which is a shot of an arbitrary background and a material-side image which is a shot of a composition material against the same background as that of the background-side image; and performing comparison processing on the background-side image and the material-side image to generate a composition image in which the composition material is extracted, the comparison processing includes comparing color values between the background-side image and the material-side image in respective areas of comparison lying in the same positions in respective frames of the same timing, the areas of comparison including one or more pixels and collecting color information on a certain area of comparison from a group of frames for a predetermined duration of the background-side image along a time axis, thereby generating a background-side color information set; collecting color information on the certain area of comparison from a group of frames for the predetermined duration of the material-side image along the time axis, thereby generating a material-side color information set; and comparing the background-side color information set and the material-side color information set along the time axis, thereby generating composition color information on the certain area of comparison of the composition image wherein: when a point in time is detected where the background-side color information set and the material-side color information set have a difference smaller than a predetermined threshold, color information on periphery of the certain area of comparison at the point in time is acquired from the frame of the material-side image at the point in time; and the color information on the periphery is consulted to judge whether or not to set the color information of the material-side color information set for the composition color information.
