Image processing method, image processing device, equipment, medium, and infrared imaging device

The invention discloses an image processing method, which is used for an infrared imaging device. The image processing method comprises steps that an image 1 and an image 2 are acquired, and an acquisition time interval between the image 1 and the image 2 is smaller than a time threshold; the acquisition time of the image 1 is earlier than the acquisition time of the image 2; inter-frame displacement between the image 1 and the image 2 is calculated; according to the inter-frame displacement, whether a pixel value error of a pixel point in the image 2 corresponding to the pixel point in the image 1 is greater than an error threshold; when yes, the pixel point, the pixel value error of which is greater than the error threshold, in the image 2 is determined as a blind pixel. By adopting theimage processing method provided by the invention, the accurate marking of the blind pixel is realized under a precondition of controlling costs. The invention also discloses an image processing device, equipment, readable st
