    摘要: An image processor realizing noise removal and contour line emphasis simultaneously. A high-pass filter (1) outputs the high-pass components h(m,n) of input image data f(m,n). An emphasis control amount deriving section (2) determines an emphasis control amount e(m,n) by subjecting the input image data to discrete wavelet conversion. A multiplying section (3) determines and outputs the product of the emphasis control amount e(m,n) from the emphasis control amount deriving section (2) and the high-pass components h(m,n) from the high-pass filter (1) for each pixel. An amplifying section (5) multiplies the output from the multiplying section (3) by a fixed factor (λ times). An adding section (4) adds the product from the multiplying section (3) and the image data to produce output image data.
