Patent ID: 8243173

Claim:
An image processing equipment, comprising: a line memory sequentially storing respective pixel values of pixels arranged in N rows M columns included in a processing object image and having a fewer number of rows than the N rows; an image reducing part sequentially generating a portion of a reduced image based on a portion of the processing object image stored in the line memory; a reduced image storing memory storing the reduced image generated at the image reducing part; a noise extracting part extracting a noise component of a noise filtering object pixel from an area in the reduced image stored in the reduced image storing memory, the area being selected to include the noise filtering object pixel; an up-sampling part calculating a noise component corresponding to a noise filtering object pixel of the processing object image by performing an up-sampling processing on the noise component being extracted; and a noise subtracting part performing subtraction of the noise component calculated at the up-sampling part from a pixel value of the noise filtering object pixel of the processing object image stored in the line memory, and outputting a pixel value after the subtraction.
