There is disclosed a display device for a copier, such display unit being provided with a display generator which generates signals at a determined time interval. A microcomputer is provided with a program interruption port for receiving the signal from the signal generator and performs dynamic drive of the display unit by the signal. The dynamic display control is achieved by interruption signals externally supplied at a determined time interval to the computer. Therefore, a constant display drive timing is maintained regardless of the execution time of the main program and an ensured dynamic display control without flicker in display is obtained.

An image processing apparatus having an input unit for entering image information, a setting unit for setting the processing conditions for processing the image information entered from the input unit, and a processor for processing the image information entered from the input unit according to certain processing conditions, wherein the setting unit is adapted to set numerical data included in the processing conditions in the form of variables.
摘要:
An image forming apparatus capable of accurate recording of input image information through a real-time image processing. It is also capable of simultaneously driving plural recording units, and of avoiding distortion in the recorded image even when the recording unit is not synchronized with the input information. These features are attained by the use of plural memories successively selected for image signal recording and for signal read-out, wherein at least one of the memories has no access while others are used for signal write-in and read-out.
