摘要： An image processing apparatus includes a first edge extraction unit, an edge processing unit, a second edge extraction unit, a third edge extraction unit and a gradation processing unit. The gradation processing unit performs gradation processing on image data on which edge processing has been performed by the edge processing unit, and switches contents of the gradation processing on the basis of whether a pixel of the image data is a third edge pixel or a no-third edge pixel to enhance a third edge region as compared with another region. The third edge extracted by the third edge extraction unit is constituted of a first edge extracted by the first edge extraction unit as an edge pixel of an object and a second edge extracted by the second edge extraction unit as a pixel having a pixel value changed by the edge processing.
