Shooting method, device and equipment

Abstract

The invention discloses a shooting method. The method is applied to a shooting terminal, and the shooting terminal comprises a first camera, a second camera and a third camera, wherein the first camera and the third camera are color cameras, the second camera is a monochrome camera, the resolution of the second camera is greater than the resolution of the first camera and the third camera, and thefirst camera, the second camera and the third camera are all prime lenses; and the equivalent focal length of the third camera is greater than the equivalent focal length of the first camera and thesecond camera; and the method includes the following steps: acquiring a target zoom ratio; determining a target lens from the first camera, the second camera and the third camera according to the target zoom ratio; acquiring an image including a target scene by using the target lens; and obtaining an output image of the target scene according to the image including the target scene, wherein the target scene is a scene that a user expects to shoot. According to the scheme of the invention, an approximately 5x lossless zoom effect can be achieved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a shooting method, device and equipment. Background technique [0002] Zooming is one of the most commonly used modes for taking pictures. Sometimes users need to take close-ups of distant objects, such as distant statues, portraits 3-5 meters away, etc.; sometimes users want to adjust the composition of the photo through zooming. For example, mobile phone users use a mobile phone to take pictures with a zoom of 2-5x most commonly used. [0003] Ways to achieve zoom include optical zoom (optical zoom), digital zoom (digital zoom) and the like. Although they all help to zoom in on distant objects when taking telephoto shots, only optical zoom can support the subject of the image and add more pixels to make the subject not only larger but also relatively clearer. This kind of zoom, which not only enlarges the subject area, but also ensures image clarity, is called lossl...

Problems solved by technology

Therefore, a common practice is to use digital zoom technology to magnify distant objects. However, this technology has an upper limit for the improvement of imaging resolution and clarity. When the magnification factor is large, the image clarity will be lost.
