1. A dual-spectrum image automatic exposure method applied to a dual-spectrum image camera, wherein the dual-spectrum image camera comprises one image sensor and a processor that are connected in sequence, wherein the dual-spectrum image camera is further provided with an infrared cutoff filter, and
wherein the method is performed by the processor, and the method comprises:
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 the infrared cutoff filter currently;
in response to determining 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
in response to determining 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, wherein the first exposure effect is the same as or different from the target exposure effect.
