A digital halftoning method for DLP projector system is proposed in this paper. PWM type 2-value images have been rapidly switched to achieve high resolution image in DLP projector systems. To achieve high frame rate image projection with high image quality, it is required to reduce the number of 2-value images with small degradation of the image quality. We propose a framework for optimizing color quantization and luminance for DLP projector system with a few number of the 2-value images. The optimal light intense is designed based on a particle swarm optimization algorithm. We illustrate the effectiveness of the proposed method by numerical examples.
