Abstract :
This paper describes the fundamentals of the image-resolved luminance and color measurement technique. Its aims and solutions are presented. The determination of image-resolved luminance and color measurements is the state-of-the- art in many applications, e.g. for road or street lighting. In today´s devices, luminance and color measuring cameras are attached to high-quality charge coupled devices (CCD) of digital cameras, each of which should be properly analyzed, calibrated and adapted to the light measurement. Light-measuring technology has developed into an important branch of light-measuring engineering. This technique provides effective solutions to a variety task in the field of light- measuring technology.
