All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flowchart of a first embodiment of the image processing method of the present invention is shown, the method of the embodiment of the present invention can be applied to a mobile phone, a tablet computer, a camera, and other camera devices capable of supporting photographing, and specifically, in the embodiment of the present invention, the method includes:
s101: and acquiring pre-shot images which are respectively shot by a front camera and a rear camera for shooting.
And opening a front camera and a rear camera of the photographic equipment, and previewing images respectively shot by the front camera and the rear camera for shooting. Specifically, the front camera and the rear camera may be set in the photographing apparatus in advance. And adjusting shooting states, such as adjusting a shooting mode, shooting parameters, a shooting background and the like, according to images respectively shot by the front camera and the rear camera displayed on the photographic equipment, and taking the images respectively shot by the front camera and the rear camera at the moment as pre-shot images after the shooting states are adjusted.
As an alternative embodiment, the rear camera may capture scenery and people, and the front camera may capture the photographer himself. Furthermore, the image acquired by the rear camera can be displayed in a full screen mode, and the image acquired by the front camera is fixed in a small screen display mode and is displayed in an overlapped mode in the upper left corner or the upper right corner of the display screen of the photographic equipment.
If the image shot by the front camera comprises a person image, filtering out a background part of the image according to the person outline, extracting the person image, and taking the extracted person image as a pre-shot image shot by the front camera. If the image shot by the rear camera contains a person and the photographer needs to shoot the image to form a group photo, a certain gap can be reserved for the photographer in advance by the shot person.
S102: and focusing the pre-shot images respectively shot by the front camera and the rear camera to respectively obtain the focal length data of the front camera and the rear camera.
After adjusting the shooting state according to the images respectively captured by the front camera and the rear camera displayed on the photographing device, and obtaining the pre-shot images respectively captured by the front camera and the rear camera, a photographer can touch any position of an image display screen to trigger execution of focusing action, after the photographing device receives a focusing instruction, the front camera and the rear camera can simultaneously perform primary focusing, and respectively obtain the focal length data of the front camera and the rear camera, for example, the obtained focal length data are respectively 2 and 10.
S103: and setting the pre-shot image shot by the front camera to the target position of the pre-shot image shot by the rear camera according to the acquired focal length data to obtain a combined image comprising the pre-shot images shot by the front camera and the rear camera respectively.
