Abstract: An apparatus has not been configured without accompanying entirely changing and revising the system LSI when the specification of the apparatus or the system LSI configuring the apparatus is changed, and also, development cost has not been able to be reduced and development period has not been able to be shortened. An image information apparatus is realized in which new functions are easy to be added into the image information apparatus without need for development of a new system LSI for each model, by installing into the image information apparatus a ubiquitous image module having configurational elements such as a hardware engine, CPU, and general-purpose bus for realizing functions that have not been provided on the image information apparatus itself, and also including an OS for operating the configurational elements.
