  • Patent number: 8559526
    Abstract: According to one embodiment, an image processing apparatus includes a decoder, a first sharpening module, and a second sharpening module. The decoder decodes an encoded image to obtain a decoded image. The first sharpening module performs first sharpening on the decoded image. The second sharpening module performs second sharpening on the decoded image subjected to the first sharpening. The second sharpening requires a different processing time from a processing time required for the first sharpening. The first sharpening module includes a first noise remover that removes noise generated by encoding from the decoded image.
