Disclosed are an image processing method, a terminal and a non-transitory computer-readable storage medium. The image processing method includes: acquiring and detecting a first image, and determining whether the first image has a face image; in response that the first image has a face image, acquiring image information of a face region where the face image is located in the first image, and calculating an average brightness in the face region based on the image information; adjusting a brightness in the face region based on the average brightness and a preset model; acquiring parameter information of each pixel in the face region, and adjusting the parameter information of each pixel based on the parameter information and a preset rule, and generating a second image; and superimposing the first image and the second image, generating and displaying a third image.

The present invention provides a method for auto-calibration of ADC, comprising acquiring a voltage signal value of a reference voltage source; converting the voltage signal value of the reference voltage source to a digital signal value according to a preset conversion coefficient value; and comparing the digital signal value to a target value and adjusting the conversion coefficient value according to the comparing result so that the difference between the digital signal value and the target value is within an allowed margin of error. The procedure of the method for auto-calibration of ADC of the present invention is executed automatically, no professional operator is needed to calibrate manually. As such, labor cost is reduced and work efficiency is improved.
