A video photometer differs from traditional photometers by utilizing a multi-element, two-dimensional detector - most typically, a CCD. This gives the video photometer the ability
to take a "snapshot" of the target and then perform photometric analysis of the captured image. Tasks such as display uniformity can be completed in a fraction of the time with a video photometer in place of a more traditional instrument because several "measurements" can be performed simultaneously on a captured image.
Like traditional "spot" photometers, the detector spectral response of Video Photometers is filtered to match the CIE Photopic response function for accurately weighted photometric measurements.
