Abstract: Specified image transformation is applied to a first source video signal to generate a main image and symmetric image transformation is applied to a second source video signal same as or different from the first source video signal in accordance with the image transformation applied to the main image and the point, line, or plane specified as a symmetry yardstick to generate a symmetric image point-symmetric, line-symmetric, or plane-symmetric to the main image. Thereby, it is possible to easily obtain a symmetric image symmetric to a main image to which image transformation is applied only by specifying a point, line, or plane serving as a symmetry yardstick.

Abstract: The transform arithmetic operations by spatial image transform matrixes and perspective transform matrixes to a screen surface thereon are executed on source video signal representing two-dimensional image so as to generate left-eye and right-eye video signals. It is possible to realize the stereoscopic image generation apparatus capable of setting the visual difference between a left eye and a right eye easily.

Abstract: Since the corner detection means (7, 9) to detect each position of the blue board area from video signal, the conversion address generation means (11) to generate the conversion address based on the position information detected and the position information showing each corner position of the image area of video signal to be inserted and the image conversion means (16) to form conversion source video signal based on the conversion address are provided and the source video signal is to be inserted to the video signal, the operator's operation adjustment as the conventional device becomes unnecessary when inserting the source video signal into the prescribed frame of the video signal, and the operation of the operator can be further decreased. Thus, a video signal processing device capable of further decreasing the operator's operation can be realized.

Abstract: An image processing apparatus and the method for mapping a plurality of images which are on the two-dimensional plane on the corresponding faces of a solid in the three-dimensional virtual space. The mapping image on the side face being close to the object image displaying face is formed in accordance with the shape of object image displaying face of the solid on which the object image is mapped, and the image mapped on each face is displaced in accordance with the movement of the solid in the three-dimensional space. Therefore, the image that as if a desired image is stuck to the faces of the solid moving in a virtual space can be displayed on a screen surface by easily operating by an operator.

Abstract: A virtual 3-D object video signal V1 is produced by performing a 3-D image transformation for a source video signal, and a 2-D objet video signal V2 for virtually representing the 3-D image transformation is produced by projecting the object video signal V1 onto an X-Y plane. Further, 3-D shadow signals V3 and V5 are produced by projecting the 3-D image transformed 3-D object video signal V1 onto a shadow plane, and 2-D shadow signals V4 and V6 corresponding to said 2-D object video signal are produced by projecting the 3-D shadow signals onto the X-Y plane. Therefore, a shadow signal for a 3-D image transformed object video signal can be produced by calculations.

Abstract: In an image special effect apparatus for forming a special effect image in which a plurality of images mutually intersect each other, the aforementioned plurality of intersecting images are allowed to be synthesized by incorporating depth information including images having residual images so that a special effect image is generated which does not provide a sense of awkwardness at a crossing point.
