The defog system includes an illuminance sensor configured to detect ambient illuminance, and at least one processor to implement a level determiner configured to determine a defog level of an input image based on the ambient illuminance. The at least one processor further implements a defogger configured to determine whether to defog the input image based on skewness and kurtosis of a histogram of the input image, and, in response to the defogger determining to defog the input image, determine a fog condition of the input image based on a cumulative probability of the histogram, and defog the input image based on the defog level."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Defog system and defog method","description":"A defog system and a defog method are provided.
