After the target photographic subject is acquired, a target portion of the target photographic subject, which has the largest variation range in the plurality of initial images, may be acquired from the plurality of initial images, and image information of the target portion of the target photographic subject in other initial images may be adjusted based on image information of the target portion of the target photographic subject in the reference image to generate an intermediate image. For example, the target portion is the hand of the user a, and the image information of the hand of the user a in the other initial image is adjusted by the image information of the hand of the user a in the reference image, so that an intermediate image or the like corresponding to the other initial image can be obtained.
According to the image information adjustment method and device, interesting processing of the ghost image can be improved through image information adjustment of the local area in the image, and then shooting experience of a user is improved.
Of course, in this embodiment, the color and transparency of the image of the target photographic object in the other initial images except for the reference image in the plurality of initial images may also be adjusted to obtain the intermediate image, and in particular, the detailed description may be made in conjunction with the following specific implementation manner.
In another specific implementation manner of the present application, the step 103 may include:
substep D1: acquiring a second image of the target photographic subject in each of the plurality of initial images except the reference image.
In the present embodiment, the second image refers to imaging of the target photographic subject in the other initial images except for the reference image among the plurality of initial images.
After the plurality of initial images and the reference image are acquired, imaging of the target photographic subject in the other initial images except for the reference image, that is, the second image, may be acquired.

In this embodiment, the closer the distance information between the second image and the first image is, the higher the color brightness of the intermediate image is, or the lower the transparency is, so that after the subsequent images are synthesized, the gradual change effect of the color or the transparency can be intuitively perceived, the viewing effect of the user can be improved, and the shooting experience of the user is further improved.
It should be understood that the above-mentioned embodiments are only examples for better understanding of the technical solutions of the embodiments of the present application, and are not to be taken as the only limitation to the present embodiments.

In this embodiment, a layered-superposition image synthesis mode may be adopted, that is, a plurality of intermediate images are layered-superposed on a lower layer of the first image in the reference image to obtain the target image, and it can be understood that in the layered-superposition mode, the first image is located on an uppermost layer, and the closer the imaging distance of the target photographic object in the intermediate image to the first image, the higher the layering is, so that the effect of gradation can be intuitively perceived.
In this example, if the intermediate image is an image in which all the target areas of the target photographic subject are replaced, the generated target image may include a ghost of the photographic subject as shown in fig. 2.
If the intermediate image is image information in which the local region of the target object is adjusted, the generated target image may include a ghost of the local region as shown in fig. 3, as shown in fig. 3.
