Abstract
The color detector circuit can be adjusted with essentially infinite variability to cause it to detect virtually any color in the visible spectrum, and to define a narrow passband or range of colors which the device will transmit. The device can be used to provide accurate color key signals with a variable passband in chroma key equipment. The device can be used to provide multiple chroma key signals for a single picture frame. A color correction system using the chroma key device also is shown.
