PURPOSE:To provide an image processor capable of realizing a high-grade image process such as multi-mixing process, etc., for plural image data. CONSTITUTION:By successively operation-processing plural image data in time- division based on priority, the multi-mixing process of these images is realized. Further, at this time, transparent process is performed by a transparent information bit incorporated in the inputted image data. This device is provided with data selectors 65, 72 selecting the inputted image data, a priority chroma key control circuit 96 driving the selectors 65, 72 based on the priority, an image special process ALU 75 operating between the output data of the data selectors 65, 72 and the output data of a time-division data latch 74, a coefficient register 130 imparting a coefficient to the image special process ALU 75 and a pixel image data latch 76 finally holding the output data of the image special process ALU 75. Thus, a mutiple translucent process is easily realized by one ALU. |
