A digital image signal processing apparatus includes a plurality of line memories, a line memory control unit that controls input image data corresponding to an input image to be input to each of the plurality of line memories and to be output from the plurality of line memories, a data patch generating unit that sequentially accesses the input image data stored in each of the plurality of line memories and generates a data patch for noise reduction filtering, and a filtering unit that performs the noise reduction filtering on the data patch and generates output image data. A digital image signal processing apparatus and method thereof thus may perform a high-speed noise reduction filtering operation and generate an output image having a same size as an input image while maintaining a same quality as the input image. |
