PROBLEM TO BE SOLVED: To obtain a noise-eliminating device capable of efficiently separating the image and noise, while attenuating only the noise. SOLUTION: The device is provided with a first input reading means 101 for reading input image block data of a predetermined block; a second input reading means 102 for reading reference data, including the vicinity of the predetermined block; an output reading means 104 for reading output image block data of the predetermined block; a comparison means 105 for comparing the size of a difference signal between the input image block data and the output image block data with a predetermined value; a searching means 106 for searching search block data correlated to the input image block data; a switching means 107 for outputting output image block update data, on the basis of a result of comparison; output writing means 111 for writing scaled output image block update data into an output image buffer 103; a and control means 112 for successively setting a plurality of predetermined blocks.
