PURPOSE:To provide a computer device capable of executing the image processing with high functionality by providing a means deciding the priority of pictures sent from different kinds and plural image data generation units. CONSTITUTION:The picture data to be dealed respective data formats are divided to the image data and area information to be operated. Then, the decision of the priority is performed by using a priority register, a priority circuit and a selector incidental to the output control of the image data and a related image processing function. The area information containing the contents of the priority register is operated by the priority circuit, and the operated result is sent to the selector. The image data are sent to the selector, and the image data are processed according to the operated result of the area information to be output ted to a D/A converter. Then, when the number of display pixels of the image data to be dealed are different from each other, the superposition of the pictures whose number of pixels are different from each other is dealed by revising the control clock of the image processing after priority while considering the priority of the pixel at a fixed pitch. |
