So far, the principle of speckle reduction by moving diffuser is confirmed on a single pixel on the screen or the eye retina through the statistical calculation of speckle contrast. We report the Monte Carlo simulation which expands the speckle reduction calculation over a finite but statistically meaningful size of pixel array on the image, applying image processing technique known as interpolation by zero padding in frequency domain. The calculated speckle contrast of the extracted speckle from the intensity distribution over the pixel array showed a good agreement with theoretical speckle contrast calculated from the temporal and spatial diversities.
