Abstract: Each of plural image processing means is informed of address information of storage means in which image data to be read is stored upon request of the image data to be read by each of the plural image processing means. Consequently, each of the image processing means can read each of image data to be read directly from the storage means based on the informed address information so as to subject it to predetermined image processing. Thus, it is possible to perform plural independent image processing in parallel at a high speed with the simple configuration.

Abstract: To control articulated robots by dynamically modifying a combination of a hardware-dependent middleware layer and a hardware-independent application layer. An interface and a database for semantically performing operation are prepared between a middleware layer which depends upon the hardware configuration of a robot and an application layer which does not depend upon the hardware configuration, thereby making it possible to always guarantee normal operation even if a combination of the middleware and the application which is to be introduced onto the robot is modified. The application can acquire appropriate input data via the middleware, and can issue an appropriate command.
