ABSTRACT:
A correlated color temperature measuring device for measuring the color temperature of light includes a sensor which individually senses plural light components of light incident thereon and for providing plural corresponding digital color component signals representative thereof, a memory which stores correction data for correcting the plural digital color temperature component signals, and a processor which receives the plural digital color component signals from the sensor. The processor accesses the correction data in the memory, corrects the plural color component signals from the sensor based on the correction data and derives a digital signal representative of the color temperature of the incident light. The derived digital signal may be displayed on a digital display or may be outputted on a digital I/O interface in response to a request for digital color temperature information.
