ABSTRACT:
An image processing apparatus processes image data stored in a memory to thereby display an image on a display screen of a display unit under a control of a central processing unit (CPU). In one aspect of the invention, source data read from a source area of the memory are subjected to a rotation process and a logical operation and then converted to transfer data which will be written in a destination area of the memory by every word. In addition, first and last words within one line on the display screen are masked in accordance with predetermined first and second mask data. In another aspect of the invention, one of a wait mode and a not-wait mode is selected by wait control data outputted from the CPU. In the wait mode, the CPU is subjected to a wait state even in a memory read cycle. In the not-wait mode, the CPU is not subjected to the wait state normally in the memory read cycle. However, the CPU is subjected to the wait state in the not-wait mode while a reading operation of the memory has not been completed.
