In the past, a number of visual effect methods for generating a halftone image from a photographic image have been proposed. In this paper, we propose a visual effect method for generating a halftone-dot-like image from the photographic image. Our method is executed by an iterative calculation using inverse filtering and minimum/maximum values of adjacent pixels. Our method is simpler than conventional methods for generating the halftone images, and can generate images with different patterns while preserving edges compared with conventional methods. Furthermore, our method can be used as unsharp mask by decreasing the value of the parameter of inverse filtering. To verify the visual effects of our method, we conduct an experiment with changing the value of the parameters and an experiment using various photographic images. As a result of the experiments, we found that our method can generate the halftone-dot-like image automatically, and clarified how to generate the halftone-dot-like patterns according to the value of the parameters in our method.
