Abstract: Disclosed are a mask wearing detection method and apparatus, and an electronic device. The method includes: acquiring a schlieren image of a subject under detection; and based on an airflow intensity corresponding to the schlieren image, determining a detection result corresponding to the subject under detection; wherein the detection result includes not wearing a mask or wearing a mask.

Abstract: An image processing method includes: if a historical image frame is determined as an overexposed image frame according to historical brightness data of the historical image frame collected by an image collector, continuing image collection by using a preset image collection parameter to obtain an underexposed image frame; processing a target region of the underexposed image frame based on at least one preset image gain parameter and determining statistical brightness data of the target region processed based on the at least one preset image gain parameter; determining a target image gain parameter according to the statistical brightness data, preset brightness data, and the at least one preset image gain parameter and determining a target image collection parameter according to the target image gain parameter and the preset image collection parameter to continue the image collection according to the target image collection parameter.
