Description

Image processing method, device, electronic equipment and storage medium Technical Field The present disclosure relates to the field of image processing technologies, and in particular, to an image processing method, an image processing device, an electronic device, and a storage medium. Background The camera of the mobile phone is generally configured with a plurality of cameras and has different focal segments to achieve the best photographing effect under different FOV (Field of view). In general, a middle-low-end mobile phone is provided with a wide-angle lens and a UW (ultra wide-angle lens), and a high-end mobile phone is provided with a tele (tele lens), wherein the magnification of the tele relative to the wide is different from 2x to 10 x. Generally, when a user takes a photograph, the user actively zooms the preview screen in the preview interface to obtain the expected fov, and the mobile phone automatically switches to the matched lens according to fov required by the user. And when photographing, saving the picture under the corresponding fov. Such photos, in album, have poor editability for post-processing. For example, if the zoom-in is large enough, the zoom-out cannot be performed to obtain a larger fov, and if the zoom-in is large enough, a lens with better image quality cannot be called. When the current prior art scheme achieves the zoom-out operation, a larger fov is obtained. However, in the amplifying operation realized by the related technical scheme, the image of the camera with better image quality is called, and the main reason is the resolution problem. For example, a mobile phone is provided with 3 cameras of 12M, and focal length values of the 3 cameras are respectively 0.5x, 1.0x and 2.0x. As shown in fig. 1, when the image of the 2x camera is called during the zoom-in operation, and the image quality of the 1x camera is ensured not to be lost, when the image of the 1x camera is spliced into the image of the 0.5x camera, the image of the 12M 0.5x camera needs to be up-sampled to the up-sampled 0.5x image of 48M (12 m×4), and then the image can be spliced with the image resolution of the 1.0x camera of 12M. And (3) zooming on the 48M images which are spliced by the user, and downsampling the images into 12M images according to the image area selected by the user when the images are stored. To align fov and resolution of a 2x camera, 1x up-samples to 48M (12M x 4), 0.5x up-samples to 192M (12M x 4), then the images of 192M are combined and the images of 192M are manipulated. Processing the pictures in this way tends to cause problems with the slowness of the electronic device.

In some embodiments, the cropping out of the portion of the first image that does not overlap with the content of the editing range acted by the editing operation, to obtain a first image area, and displaying the first image area includes: in the image preview process, when the content display refresh rate of the editing range is greater than or equal to a first preset threshold value, adjusting the image resolution of the first image area to the display resolution of the electronic equipment; displaying the first image area after the image resolution is adjusted to the display resolution. In some embodiments, the method comprises: When the content display refreshing rate of the editing range in the image preview process is smaller than the first preset threshold value, adjusting the image resolution of the first image area and the image resolution of the second image area to the display resolution of the ele
