Abstract
A novel image processing apparatus allows sophisticated but simple image processing with respect to a plurality of input video data, for example, multi-stage data mixing or multiple semi-transparent process. In the image processing apparatus of the invention, a plurality of video data are processed by a predetermined time-sharing operation according to a priority sequence so as to be superposed one upon another. Transparency processing is also executed based on a transparency information bit included in input video data. The image processing apparatus includes data selectors 65 and 72 for selecting video data to be input, a priority sequence chromakey control circuit 96 for driving the data selectors 65 and 72 based on a predetermined priority sequence, a specific image process computing element 75 for executing a predetermined operation with respect to output data of the data selectors 65 and 72 and output data of a time-sharing data latch 74, a coefficient register 130 for determining coefficients used in the operation by the specific image process computing element 75, and a pixel image data latch 76 for finally holding output data of the specific image process computing element 75.
