摘要

To provide an image processing apparatus in which image filtering, required in the video coding/decoding process is performed more efficiently with high quality.SOLUTION: A limited linear filtering section of an image processing apparatus has a limit value processing section for changing the absolute value of the differential value to a predetermined value less than a differential limit value, when there is a differential value exceeding a predetermined differential limit value in the differential value of pixel value of an object pixel and a peripheral pixel, and a linear filtering section for receiving the pixel value of the object pixel and each differential value of each peripheral pixel after change processing, and performing linear filtering based on the linear filter factor, and outputs the pixel value of the object pixel after linear filtering.SELECTED DRAWING: Figure 1
