Example one

Fig. 3 is a flowchart of a first embodiment of a method for capturing a moon image according to the present invention. A method of capturing a moon image, the method comprising:

and S1, opening a view interface of moon shooting, acquiring astronomical auxiliary information, and judging whether the moon image is contained in the view interface according to the astronomical auxiliary information.

And S2, if the moon image is contained in the view interface, carrying out composition adjustment and focusing adjustment according to the position of the moon image in the view interface, and receiving a shooting instruction after adjustment.

And S3, controlling a first camera to shoot a first image and a second camera to shoot a second image according to shooting parameters corresponding to the shooting instruction, and acquiring a first crescent position coverage area in the first image and a second crescent position coverage area in the second image according to the astronomical auxiliary information.

And S4, covering the second moon position coverage area in the second image to the first moon position coverage area in the first image to obtain a fused moon shooting image.

Optionally, in this embodiment, it is considered that the moon shooting is one of the usage scenarios of many mobile terminal device users, and when the moon is shot by using a mobile terminal device such as a mobile phone, a clear moon can be shot only by the user adjusting relatively complex shooting parameters in a professional mode; in order to reduce the operation difficulty, in some optional alternative schemes, multiple cameras work cooperatively, namely, multiple pictures are obtained by shooting under different parameters, and the pictures with clear backgrounds and clear moons are obtained by fusing the multiple pictures, so that the user operation is simplified to a certain extent, and the imaging effect is improved. However, in the image fusion process, because the position of the moon main body is determined by adopting a traditional image recognition mode, a relatively serious wrong fusion effect is often caused by a wrong calculation of the moon position, for example, a street lamp, a window with a bright lamp, or other bright objects are likely to be recognized as the moon, so that the fused image can replace the bright objects of various types with the moon, great trouble is brought to a user, and the shooting experience is seriously reduced.

Therefore, the embodiment provides a moon image shooting scheme, which includes firstly, opening a view interface of moon shooting, acquiring astronomical auxiliary information, and judging whether a moon image is included in the view interface according to the astronomical auxiliary information; then, if the moon image is contained in the view interface, composition adjustment and focusing adjustment are carried out according to the position of the moon image in the view interface, and a shooting instruction is received after adjustment; then, controlling a first camera to shoot a first image according to shooting parameters corresponding to the shooting instruction, controlling a second camera to shoot a second image, and acquiring a first moon position coverage area in the first image and a second moon position coverage area in the second image according to the astronomical auxiliary information; and finally, covering the image of the second moon position coverage area in the second image to the first moon position coverage area in the first image to obtain a fused moon shooting image.

Optionally, in this embodiment, in the moon image capturing mode, the user is prompted to move the terminal device in the direction according to the position of the moon in the viewing interface and a predetermined or preset composition rule, so as to help the user obtain a better composition.

Optionally, in this embodiment, after determining that the composition is complete, the focus is adjusted to capture the first image and the second image according to the position of the moon within the viewing interface.

Optionally, in this embodiment, an astronomical auxiliary image system is obtained based on the astronomical auxiliary information, and the position and shape of the moon, for example, the round sky, etc., are obtained by the system.

Alternatively, in the present embodiment, when the moon is recognized, the moon image capturing mode is automatically turned on; under the support of the astronomical calculation auxiliary image system, scene error identification is effectively avoided.

Alternatively, in the present embodiment, multiple images are captured under different parameters by using multiple cameras in cooperation with each other.

Optionally, in this embodiment, a plurality of images are fused according to the position, size, and shape of the moon, so as to obtain a moon image with a clear background and a clear and beautiful moon, wherein under the support of the astronomical computation aided imaging system, the occurrence of image fusion errors is effectively avoided.

The method has the advantages that astronomical auxiliary information is acquired by opening a viewing interface shot by the moon, and whether the moon image is contained in the viewing interface is judged according to the astronomical auxiliary information; if the moon image is contained in the view interface, carrying out composition adjustment and focusing adjustment according to the position of the moon image in the view interface, and receiving a shooting instruction after adjustment; controlling a first camera to shoot a first image according to shooting parameters corresponding to the shooting instruction, controlling a second camera to shoot a second image, and acquiring a first moon position coverage area in the first image and a second moon position coverage area in the second image according to the astronomical auxiliary information; and covering the image of the second moon position coverage area in the second image to the first moon position coverage area in the first image to obtain a fused moon shooting image.
