A method of coding a moving picture is provided that reduces blocking artifacts. The light source module can generate a first beam, while the optical module can relay and uniformize the first beam so that the first beam is uniformly incident on the phosphor element. The emitter region and the body region are located in a surface portion of each channel region. In other words, the region may be enlarged along one axis, while reduced along the other axis, or either enlarged or reduced by different magnitudes along the x, y axes. A processing engine may generate a user interface from the parameters defined in the models, customize the scripts from the user input, and cause the scripts to be executed.
