(57) Abstract: An object of the present invention is to provide an image processing apparatus capable of performing edge enhancement with little influence of noise components. In a vertical processing circuit, a SUB1 is provided. In 4a, 15a, and 16a, the difference between the image data of the four pixels adjacent in the vertical direction is calculated, and the value of each difference is changed based on the magnitude and sign of the difference. Then, image data of four pixels is generated using each changed difference. In the horizontal processing circuit 3b, the SUBs 14b, 15b, At 16b, the difference between the image data of the four pixels adjacent in the horizontal direction is calculated, and the value of each difference is changed based on the magnitude and sign of the difference. Then, image data of four pixels is generated using each changed difference. |
