Finding the ideal Correlated Color Temperature (CCT) or White Point value for specific scenes can be very difficult. Diverse light sources and conditions can distort the color and quality of an image and mixed light sources increase this effect. Even normal objects in a room or scene distort the perceived CCT value, from the actual value of the light source (red wall, blue sky, green forest). Flickering light sources or background items like displays affect the quality of an image.
Spectral Ambient Light Sensors measure the light source and perform a spectral estimation of the CCT vs. the distortion effects of other influences. The system can now use the measured value alongside with the detected light source to find an ideal white point CCT value. An integrated flicker chip can eliminate environmental flicker effects and synchronize the cameras shutter times. This sensor enables the measurement of the Color Rendering Index (CRI) value of an image. The Spectral ALS Sensor activates post-processing improvement options.
