Abstract: An image control apparatus includes a communication control unit for effecting a communication with the outside of the apparatus, an image processing control unit for controlling processings required for a given image data, and a main control unit for controlling the communication control unit and the image processing control unit. Respective control units are provided on separate printed boards, respectively, and each printed board is connected to each other using respective connectors. By the constitution, it is possible to make a maximum use of resources such as hardware resources and thereby improve an efficiency in development of the image control apparatus. Also, by mounting the above printed boards with being divided into lower-side units and upper-side units, it is possible to increase the component mounting space and to have the printed board drawings for common use.
