Abstract:
1. An image processing method comprising: a dividing step of dividing input image data including a character portion and an image portion into first image data representing gradation of the character portion and second image data representing gradation of the image portion; a reducing step of reducing a resolution of a non-character image represented by the second image data obtained by the dividing step and obtaining low resolution second image data; an acquiring step of acquiring the first image data and the low resolution second image data, wherein the resolution of the image represented by the low resolution second image data is lower than the resolution of the image represented by the first image data; a first generating step of generating first dot data indicating whether to form a dot for forming an image of the characters, from the character portion, on a recording medium, in accordance with a gradation value of each pixel in the first image data acquired in the acquiring step; a second generating step of generating second dot data indicating whether to form a dot for forming an image of the non-character image on the recording medium, in accordance with a gradation value of each pixel in the second image data acquired by the acquiring unit; and a third generating step of generating, on the basis of the first dot data generated in the first generating step and the second dot data generated in the second generating step, image formation data for forming an image on the recording medium.
