PROBLEM TO BE SOLVED: To easily prepare a composed picture having no sense of incompatibility by generating a CG picture for composition based upon estimated three- dimensional(3D) space information and executing perseptive projection conversion for the CG picture to compose an actual picture. SOLUTION: When information is inputted from an information input part 28 while observing an actural picture on a display 14, a visual point information calculating part 22 estimates visual point position information from the already inputted actual picture. Then a CG picture generating part 24 generates a CG picture to be composed by using 3D space information read out from a memory 12. The generated CG picture is outputted to a picture data composing part 26. In the composing part 26, when the already estimated visual point position information, light source information, etc., are inputted from the memory 12 together with the actural picture data, the shadowing processing on the arrangement position of the actual picture is applied to the inputted CG picture, then the composition processing of both the pictures is executed. |
