Effects of quantization and pixel structure on the image quality of color matrix displays

A model is presented for the effects of luminance quantization and pixel geometry on the image quality of color matrix displays. For this model, the square-root integral is used and the quantization effect is described as a form of noise. The square-root integral expresses the subjective image quality of a picture in a figure that depends on the physical parameters of the image. It describes the effects of resolution, luminance, contrast, image size, viewing distance, and noise on image quality. Image quality measurements of various authors are analyzed and compared with calculations based on this model. From the comparison, it appears that the measurements agree very well with the theoretical predictions.<>
