ABSTRACT:
A plurality of image input devices and a plurality of image output devices are connected to a system bus and an image bus of an image processing system through an external device control unit. The image processing system comprises a host CPU, an image processing unit, a CRT and multiple input and output devices, which are connected with each other through the system bus and the image bus. The external device control unit comprises a control CPU for controlling various processing based on various commands, a switch connected to each of the image input/output devices and to the image bus for switching combinations of connections of the image imput/output devices based on an instruction from the control CPU, a dual port for exchanging information between the host CPU and the control CPU through the system bus. An image input device can be connected directly to a desired image output device and the connected image input/output devices can be activated by an input from the operating unit of the image input device, without being subjected to the instruction from the host CPU.
