Spectral sensitivity (iQ-LED)

The Spectral sensitivity (iQ-LED) module is intended to help identify the parameters for high-speed
production-line camera colorimetric calibration using Image Engineering illumination devices that embed iQ-
LED technology. While the Spectral sensitivity (camSPECS) module directly determines a camera's spectral
sensitivities, the Spectral sensitivity (iQ-LED) module determines the spectral sensitivities of production-line
cameras. Images captured from a few LEDs combined with an analysis of a database of reference spectral
sensitivities from cameras with the same make and model sampled from production. The database is created
with a monochromator such as camSPECS then data from a test camera is selected for parameter
optimization and comparison of results as described below. This process can be repeated for additional test
cameras to confirm that the optimized parameters are robust across the cameras under test.
