Problems solved by technology

But in fact, as far as the focal length is concerned, each camera device has a certain error during assembly, and its actual focal length is also different from the theoretical reference value given by the lens manufacturer; as for the optical axis, the two camera devices assembled in When they are together, the optical axes will also produce errors instead of being absolutely parallel, resulting in incomplete observation directions of the two cameras, which will lead to poor user experience when switching cameras

Abstract

The present invention provides an image processing method, device, electronic equipment, and computer-readable medium, relating to the technical field of image processing, including: acquiring a first image captured by a first camera device; and determining a target in the first image ROI area; calculate the ROI offset of the target ROI area in the first image and the second image; obtain the current magnification of the first image, slice the ROI offset according to the current magnification, and obtain the first image at the current moment Perform the current superposition offset of image stereo correction; perform image stereo correction on the first image based on the current superposition offset to obtain the corrected first image; The camera device is switched to the second camera device for display, and the present application alleviates the technical problem of obvious jumps in the imaging switching of the camera device in the prior art.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device, electronic equipment and computer readable medium. Background technique [0002] For a mobile terminal, its camera device is usually a fixed-focus lens, which can only achieve digital zoom. As consumers have higher and higher requirements for functions such as shooting and video recording, in order to solve the defects of digital zoom at high zoom ratios, more and more mobile terminals are equipped with two or more cameras with different focal lengths. The camera devices are matched, for example, one lens FOV (field angle, field angle)=80°, and one lens FOV=40°. At this time, digital zoom and optical zoom can be combined to satisfy consumers. The combination of digital zoom and optical zoom means that one camera device is used to enlarge the image and then switch to another camera device for imaging. The above method is also ...
