In the computer-generated hologram technology, speckle noise is one of the important problems. When using a speckle contrast as an evaluation measure of the speckle noise,
We can evaluation only viewed from one viewing position, so it is impossible to correctly evaluate the quality of the actual three-dimensional image.
In this study, we propose a practical method for evaluating the speckle noise for application to three-dimensional image display by considering the viewpoint movement of the observer.
