Image processing method for reducing imaging artifacts |
摘要 |
An image processing method includes a step of converting halftoned pixels of an image to be printed represented at a first lower tonal resolution into pixels represented at a second higher tonal resolution. Image processing is used on the pixels having a higher tonal resolution to reduce image quality artifacts when the pixels are printed at the first lower tonal resolution. In a preferred embodiment, the image processing includes error diffusion of a sigma delta modulation.
