Image information apparatus and module unit
First Claim
1. An image information apparatus comprising:
- an image-information-apparatus main unit including a first central processing unit, and a connection interface for connecting with a module unit that has a second central processing unit for controlling the first central processing unit;
wherein;
the first central processing unit and the second central processing unit each have a plurality of hierarchical control strata, and the second central processing unit included in the module unit is configured to transmit, between each of the hierarchical control strata of the first central processing unit and respectively corresponding hierarchical control strata of the second central processing unit, control information related to each of respectively corresponding hierarchical control strata, so as to control the image-information-apparatus main unit.

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.

16. A module unit comprising:
-
a connecting portion connected to a connection interface of an image-information-apparatus main unit that includes a first central processing unit having a plurality of hierarchical control strata, and the connection interface; and
a second central processing unit having hierarchical control strata corresponding to the hierarchical control strata of the first central processing unit, and for transmitting, from the hierarchical control strata of the second central processing unit through the connecting portion, control information for controlling the hierarchical control strata of the first central processing unit, so as to control the first central processing unit;
wherein by controlling the first central processing unit, processed information including image information is outputted from the image-information-apparatus main unit. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
