Abstract:
The present application relates to the field of image processing, and in particular relates to an image correction method, an apparatus, and a storage medium. The method comprises: obtaining a first image photographed by a camera that has an optical image stabilization mode enabled, and obtaining first displacement data corresponding to the first image, the first displacement data indicating lens displacement when the first image was being photographed; converting the first displacement data into a first image angle of rotation according to calibration information, the calibration information comprising a correspondence relationship between an image angle of rotation of a calibration image photographed by the camera and calibration displacement data, and the first image angle of rotation indicating image rotation of the first image; performing image correction on the first image according to the first image angle of rotation, and outputting a second image. In an embodiment of the present application, first displacement data is converted into a first image angle of rotation according to calibration information, image correction is performed on the basis of the first image angle of rotation, and image rotation errors caused by an OIS device when photographing are reduced or eliminated.
