Dual-spectrum image automatic exposure method and apparatus, and dual-spectrum image camera and machine storage medium

A dual-spectrum image automatic exposure apparatus 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 apparatus is disposed in the processor, and the apparatus comprises:
• an original image acquisition module configured to acquire an original image collected by the image sensor;
• a logical light splitting module configured to perform logical light splitting processing on the original image to obtain an infrared image and a visible light image;
• a filter determination module configured to determine whether to use infrared cutoff filter;
• a single-spectrum exposure control module configured to, if it is determined to use the infrared cutoff filter, perform 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
• a dual-spectrum exposure control module configured to, if it is determined not to use the infrared cutoff filter, perform 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.
