1. An image processing apparatus for processing input image data and for outputting output image data, the image processing apparatus comprising:

  • an edge detection unit for detecting an edge gradient direction with the largest gradient of pixel values and an edge direction orthogonal to the edge gradient direction for each pixel of the input image data;

    an edge direction processing unit for performing smoothing processing on the image data in the edge direction for each pixel of the output image data in accordance with a detection result of the edge detection unit and for sequentially outputting pixel values corresponding to respective pixels of the output image data; and

    an edge gradient direction processing unit for performing edge enhancement processing in the edge gradient direction on the pixel values output from the edge direction processing unit for the respective pixels of the output image data in accordance with the detection result of the edge detection unit and for sequentially outputting pixel values of the output image data.
