VIDEO SIGNA; PROCESSING DEVICE AND METHOD EMPLOYING TRANSFORMATION MATRIX TO GENERATE COMPOSITE IMAGE

A video signal processing device includes an address generator to calculate a transformation matrix for three-dimensionally transforming an image to a “blue board” area. The transformation is based on corner positions of the blue board area of a video signal and those of an image area of a source video signal to be inserted. Address information is calculated for reading the source video signal from a memory based on an inverse matrix of the transformation matrix. In this way, the image area to be inserted can be three-dimensionally transformed and automatically inserted into the blue board area, without requiring an operator to input parameters indicative of a post-transformation state.
