Optical zoom can achieve the advantage of changing the size of the picture without losing the quality of the projected picture. From the projection screen shot, it can be seen that the picture adjusted by the optical zoom will still maintain brilliant and clear images, and the picture quality will be truly lost. The digital zoom uses an image processor to individually enlarge the image information obtained by the light sensing unit in a certain area of ​​the light sensing element. However, this simple enlargement is in fact exactly the same as the local enlargement in the image processing software, and has no use value at all.
