<p><P>PROBLEM TO BE SOLVED: To provide an image processor whereby a processed image can be viewed in a state that a noise reduction effect and deterioration in image quality are well balanced at all times in the case of reducing noise included in a video signal and block noise caused when a signal resulting from applying high efficiency coding to the video signal is transmitted. <P>SOLUTION: The image processor is provided, wherein a viewer can view an image with image quality well-balanced in response to a viewing position by obtaining a subtraction signal, used for a subtraction section 102 for subtracting a noise component from the video signal in a cyclic type noise reduction circuit using a frame memory, through a nonlinear conversion section 106 capable of varying a noise reduction level and a deterioration degree of edge image quality of a moving image depending on a distance (view distance) between the display apparatus and the viewer. Similarly, the image processor is acquired, wherein the image quality of the image is controlled to attain well-balancing in response to the viewing position by detecting the block noise so as to vary a degree of smoothness of a pixel level at block borders depending on the view distance. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
