Abstract: A method includes: capturing at least two frames of first images at a same exposure time using a first camera, and capturing at least two frames of second images at different exposure times using a second camera, where a capturing time of the first images and a capturing time of the second images are the same; determining a first reference image from the at least two frames of first images; performing moving target detection on an image other than the first reference image in the at least two frames of first images according to the first reference image to obtain a local motion magnitude that is of the image other than the first reference image in the at least two frames of first images and that is relative to the first reference image; and performing image fusion on the second images according to the local motion magnitude.

Abstract: Obtaining a first set including key point descriptors in a first image that is of a to-be-shot scene and that is formed by using a first camera in a dual camera system, and a second set including key point descriptors in a second image that is of the to-be-shot scene and that is formed by using a second; pairing a key point in the first set and a key point in the second set that match each other to form a key point pair; selecting the key point pair that meets a predetermined condition; generating an image alignment vector field according to the selected key point pair; and estimating an occlusion area according to the depth information of the first image and the second image, and eliminating an alignment vector of the occlusion area in the image alignment vector field, to form a corrected image alignment vector field.

Abstract: A photographing method for a terminal that comprises a monochrome camera and a color camera, the method including simultaneously photographing a same to-be-photographed scene using the monochrome camera and the color camera and separately obtaining K frames of images, where the monochrome camera uses a full-size operation mode, where the color camera uses a binning operation mode, and where K≥1, obtaining a first image corresponding to the monochrome camera and a second image corresponding to the color camera, obtaining high-frequency information according to the first image, obtaining low-frequency information according to the second image, and fusing the first image and the second image according to the high-frequency information and the low-frequency information, and generating a composite image of the to-be-photographed scene.
