Abstract: Embodiments of the present disclosure provide an image processing method and apparatus, a device, a medium and a product. The method is applied to a head-mounted device, where the head-mounted device includes a first camera set to be in a rolling shutter mode and a second camera set to be in a global shutter mode, and the method includes: obtaining a first image acquired by the first camera and a second image acquired by the second camera; obtaining target gain information between the second image and the first image by performing image difference analysis on the first image and the second image; obtaining a target frequency domain image by using the target gain information to repair the first image in a frequency domain; obtaining a target image corresponding to the first image by converting the target frequency domain image from the frequency domain to a time domain.
