Patent ID: 7602998

Claim:
An image signal processing apparatus comprising: a plurality of image processing function blocks; a plurality of individual image processing parameter tables in which individual image processing parameters specifying the contents of individual operations are set for each of said plurality of image processing function blocks; a composite processing parameter table in which composite processing parameters specifying a processing order of said plurality of image processing function blocks are set; and a local control CPU that operates corresponding image processing function blocks successively in the processing order specified in said composite processing parameters and according to the contents of respective individual operations specified in the individual image processing parameters for respective image processing function blocks to be operated, wherein when an individual image processing command is issued, one image processing function block to be operated is operated according to the contents of the individual operations specified in the individual image processing parameters for said image processing function blocks, and when a composite processing command is issued, the plurality of image processing function blocks to be operated are operated successively in the processing order specified in the composite processing parameters, and wherein when a composite processing command is issued, the contents of said individual processing parameter table that is directly readable/writable by an external host CPU and said composite processing parameter table are copied to an internal parameter table, the operation order of the plurality of image processing function blocks to be operated is controlled with reference to the composite processing parameters copied to said internal parameter table as image processing order information and the image processing function blocks to be operated are operated with reference to the individual image processing parameters copied to said internal parameter table.
