INFORMATION SIGNAL PROCESSOR, FUNCTIONAL BLOCK CONSTITUTING THE SAME AND METHOD FOR CONTROLLING ITS FUNCTIONAL BLOCK

摘要

PROBLEM TO BE SOLVED: To facilitate upgrade by adding a functional block (processing substrate).;SOLUTION: This case body 101 is provided with slots 102a to 102d into which processing substrates 111 to 115 are selectively inserted. For example, only a high image quality processing substrate 111 is inserted into an upgrade stage 1. For example, a high image quality processing substrate 111 and a noise removal processing substrate 113 are inserted into an upgrade stage 2a. An inter-substrate command (common command) is transmitted from a control board 104 through a control bus 109 to each substrate. Each substrate is adaptively operated in response to the inter-substrate command. Each processing substrate inserted into a slot reads an image signal to be processed from the reading destination of a shared memory 108, and writes the processed image signal in the writing destination of the shared memory 108. At the time of executing upgrade by adding the processing substrate, the reading destination and the writing destination for the shared memory 108 are only changed so that each processing substrate can be connected in a desired order.;COPYRIGHT: (C)2006,JPO&NCIPI
