Embodiment Construction

[0256] The best way to implement the invention

[0257] The first embodiment of the present invention will be described below with reference to the drawings. figure 1 The configuration of the digital broadcast receiver 100 according to the first embodiment is shown.

[0258] This digital broadcast receiver 100 contains a microcomputer, and includes a system controller 101 that controls the operation of the entire system and a remote control signal receiving circuit 102 that receives remote control signals. The remote control signal receiving circuit 102 is connected to the system controller 101 and is arranged to receive a remote control signal RM output from the remote control transmitter 200 in response to a user operation and supply an operation signal corresponding to that signal RM to the system controller 101.

[0259] The digital broadcast receiver 100 also includes a receiving antenna 105 and a tuner section 106 that supplies the broadcast signal (RF-modulated signal) capture...

Abstract

An information signal processing device and the like that can be suitably applied to a digital broadcast receiver or the like. A classifying part (130) produces a class code (CL) indicative of a class to which pixel data (y) of interested position in an image signal (Vb) belong. Difference data (DF)(encoded-noise correction data) corresponding to the interested position is read, based on the class code (CL), from a storage table (131). Pixel data (x) (pixel value or DCT coefficient) corresponding to the interested position in the image signal (Vb) is supplied to an adding part (134). The adding part (134) adds the difference data (DF) read from the storage table (131) to the pixel data (x), thereby providing pixel data (y) of the interested position in the image signal (Vb). In this pixeldata (y), the encoded noise (encoded distortion) has been reduced.

Description

[0001] The present invention is an invention patent application "Information signal processing equipment, information signal processing method, image signal processing equipment, image display equipment, and equipment for generating correction data used in it on July 18, 2003 and application number 03817222.4 And methods, equipment and methods for generating coefficient data, programs for executing these methods, and computer-readable media storing the programs". Technical field [0002] The present invention relates to a device for processing an information signal, etc., which is preferably applied to reduce the coding noise of an information signal obtained by decoding an encoded information digital signal. [0003] More specifically, the present invention relates to detecting the category to which the pixel data of the target position in the output information signal belongs based on the input information signal, and using correction data corresponding to the detected category to...
