Abstract
In this paper, we propose an evaluation method for digital halftone image produced by multi-level error diffusion technique. Tone reproduction, sharpness, graininess and color reproduction characteristics of the digital halftoning images with the resolution 200, 400, 800, 1600 DPI printed on transparency by digital film recorder were analyzed both physically and subjectively. We also analyzed the relationship between the subjective evaluation and parameter calculated by linear combination of four physical parameters to evaluate image quality. As a result of the experiment, it was found that the rms granularity and parameter calculated by linear combination of each quality criterion were well correlated to the observer rating values.
