Low/No Glow IR Selection Implementations

Abstract

A camera includes an image sensor configured to capture an image of a target subject and a flash device configured to selectively illuminate the target subject with low-glow infrared light or no-glow infrared light. The flash device includes a set of first illumination devices that emit the low-glow infrared light and a set of second illumination devices that emit the no-glow infrared light. Each first illumination device includes a low-glow light-emitting diode (LED) that emits low-glow infrared light having a wavelength of about 730 nanometers to about 880 nanometers. Each second illumination device includes a no-glow LED that emits no-glow infrared light having a wavelength of about 940 nanometers or greater.
