Document Type and Number:
Japanese Patent JP4585603
Kind Code:
B1
Abstract:
According to one embodiment, an image processing apparatus includes a storage module, a calculator, a converter, and a filter. The storage module stores a filter coefficient corresponding to a first feature value indicating an image structure of a first pixel block of a predetermined size comprising a plurality of pixels. The calculator calculates a second feature value indicating an image structure of a second pixel block comprising a target pixel to be processed and pixels surrounding the target pixel in an input image. The second pixel block is larger than the first pixel block. The converter converts the second feature value to the first feature value indicating the image structure corresponding to the first pixel block with the target pixel at the center. The filter performs filtering on the first pixel block with the target pixel at the center using the filter coefficient.
