Abstract
The image of analog color TV has been analyzed by using the human visual resolution for three primary colors. However, these analysis results are not suitable for the hardcopy image that is recorded by using digital color fine dots. So, we measured the human visual resolution for digital fine dots, and got the minimum dot size that we can distinguish individual dot in each space frequency. Otherwise, we formed the reconstruction image by using the analog visual resolution and the Fourier transform, and analyzed the dither pattern image noise and quality. Further, we checked the influence that smooth edge dots or Error Diffusion Image method exert on the image quality.
