Shooting method, device and equipment

Abstract

The invention discloses a shooting method, which is applied to a shooting terminal. The shooting terminal comprises a first camera, a second camera and a third camera, wherein the first camera and thethird camera are color cameras, the second camera is a black-and-white camera, the resolution of the second camera is greater than the resolution of the first camera and the resolution of the third camera, and the first camera, the second camera and the third camera are prime lenses; and the equivalent focal length of the third camera is greater than the equivalent focal lengths of the first camera and the second camera. The shooting method comprises the following steps of: acquiring a target zoom magnification; determining a target lens from the first camera, the second camera and the thirdcamera according to the target zoom magnification; capturing an image containing a target scene by utilizing the target lens; and acquiring an output image of the target scene according to the image containing the target scene, wherein the target scene is a scene that a user expects to shoot. According to the shooting method, an approximately 5x lossless zooming effect is 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.
