摘要： 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.

摘要： An image crop circuit performs a crop process for an input video image under the control of a CPU. An image shape changing circuit performs an image shape changing process such a mosaic process for a video signal that is cropped corresponding to a control signal. The image shape changing circuit supplies the video image to a graphic inserter circuit. A GDC that is a graphic dedicated CPU draws a positive region of a contour line of the crop region as a solid line and a negative region as a dotted line. The graphic inserter circuit superimposes the contour line with the video signal that is cropped and outputs the resultant signal to both a CRT monitor and an output terminal.

摘要： 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.
