Abstract
Provided are a dual-spectrum image automatic exposure method and apparatus, and a dual-spectrum image camera. This method includes acquiring an original image collected by the image sensor; performing logical light splitting processing on the original image to obtain an infrared image and a visible light image; determining whether to use infrared cutoff filter; if it is determined to use the infrared cutoff filter, performing exposure processing on the visible light image by using a single-spectrum exposure algorithm to obtain a visible light image that conforms to a target exposure effect; and if it is determined not to use the infrared cutoff filter, performing the exposure processing on the infrared image and the visible light image by using a dual-spectrum exposure algorithm to obtain a visible light image that conforms to a first exposure effect and an infrared image that conforms to a second exposure effect.
