Conventional methods of measurement with a luminance meter are very time-consuming and they also allow recording only a limited number of pixels without the use of an automated sensing system. The problem has been solved by special measuring CCD camera technology, which enables to sense hundreds of thousands pixels in a single image and thus obtain their luminance values. However, its cost is still too high for a wider use.
