Abstract:
1. An image processing apparatus comprising: an acquiring unit configured to acquire information for controlling a degree of pixel replacement with a black pixel; a setting unit configured to set, in a case where the acquired information is first information, two pixels, one of which is adjacent to a processing target pixel in a vertical direction and the other of which is adjacent to the processing target pixel in a horizontal direction, as first determination pixels, and two pixels adjacent to and opposite across one of the two first determination pixels as second determination pixels, and to set, in a case where the acquired information is second information, four pixels, each being adjacent to the processing target pixel as the first determination pixels; and a replacing unit configured to replace the processing target pixel with a black pixel, in a case where the acquired information is the first information, one of the first determination pixels is a black pixel and one of the second determination pixels is a black pixel, and to replace the processing target pixel with a black pixel in a case where the acquired information is the second information and one of the first determination pixels is a black pixel, wherein the second information indicates the pixel replacement with a black pixel is performed to a degree larger than a degree of pixel replacement with a black pixel indicated by the first information.
