Abstract
The application provides an image processing method and an electronic device. In the process that the electronic device acquires a first image through a first camera and acquires a second image through a second camera, if the electronic device enables a focusing function, the first image is acquired after a lens in the first camera is adjusted to a first distance from a photosensitive device, and / or the second image is acquired after a lens in the second camera is adjusted to a second distance from the photosensitive device. Then, before depth estimation based on the first image and the second image, a change coefficient of the first distance relative to a first calibration distance is used to update an original first calibration focal length, the first image is corrected for distortion using the updated first calibration focal length, a change coefficient of the second distance relative to a second calibration distance is used to update an original second calibration focal length, the second image is corrected for distortion using the updated second calibration focal length, and the first image and the second image after the distortion correction are used for depth estimation.
