Patent ID: 7965319

Claim:
An image signal processing apparatus, comprising: a data path portion for processing a raw image signal, wherein said data path portion is merged and concentrated with non-linear filtering portion, color space transformation portion, geometry transformation portion, linear filtering portion and gain adjustment portion, wherein outputs from said gain adjustment portion and a local filter merger are combined at a filter construction portion to construct an intensive filtering operation output for said linear filtering portion; and a separated control and judgment portion outside of said data path portion for receiving the raw image and the processed signal from said data path portion and generating a plurality of adjustment signals for the non-linear filtering portion, color space transformation portion, geometry transformation portion, linear filtering portion and gain adjustment portion of said data path portion, wherein the separated control and judgment portion comprises a scene analysis portion for performing scene analysis, wherein the scene analysis portion supports area-dependent and scene-dependent operations for filtering and for gain adjustment, wherein an operation of the scene analysis portion is adaptively changed according a scene or an area segmented by the scene analysis block, wherein, when the adaptively changed operation requires predetermined data, the scene analysis portion sends control signals to the control part and sends raw data to a storage unit for outputting an information used to process the raw data; wherein the data path portion is adaptable to a plurality of operations and the data path portion and the separated control and judgment portions are configured to be changed to update an algorithm.
