Abstract
An infrared camera, comprising photosensitive element (101) capable of sensing infrared spectrum, gas discharge flash acting as flash light source (102), a first optical filter (103) filtering visible lights and allowing infrared light to transmit, and processing module (105) used to execute instructions, wherein the first optical filter is fixedly or removablely disposed in the emitted light path of the flash light source. Due to gas discharge flash filtering visible lights and acting as infrared light source, the camera could provide infrared lighting capability far better than infrared LED, improving the nighttime infrared photographing quality.
