Abstract

The invention discloses a realization method for improving the view finding and shooting success rate of sports question materials, which can effectively reduce view finding errors and shooting failures when a mobile phone camera shoots a sports ground surface in a zooming way and improve the success rate of shooting good photos of the sports question materials by a mobile phone. The invention has the main application that the view field is predicted by utilizing the relatively short-focus lens in a larger range, so that a photographer can know the advancing direction and the moving speed of a moving object outside an actual shooting area in advance on a view frame, thereby reserving enough time for adjusting the composition in advance and carrying out shooting after waiting for the object to enter a proper position of the actual shooting area unconsciously.

Description

Implementation method for improving view-finding shooting success rate of sports question material

Technical Field

The invention relates to the technical field of camera shooting functions of mobile phones, in particular to a realization method for improving the framing and shooting success rate of motion subjects.

Background

When the existing mobile phone camera performs zooming shooting, a view field range in a view frame and a lens focal length during shooting are in synchronous correspondence, for example, when a user zooms the lens to a focal length of 100mm for shooting, a view field picture seen on the view frame is a shooting range which can be covered by the 100mm focal length lens.

The synchronous corresponding advantage of the view field and the shooting focal length is that the view frame before shooting and the composition frame shot at last are synchronous and consistent, but the side effect is that the view field range which can be previewed and observed is narrower and narrower as the focal length is continuously lengthened and the shot scene is continuously drawn.

This narrowed viewing field is not a big problem for a still subject, but for a subject in motion, particularly a subject laterally displaced with respect to the shooting direction, the subject may instantly blink from the viewing frame, so that the photographer may miss the shutter-release optimum timing without time to respond, and the desired moving picture content cannot be shot.

The probability of occurrence of such a failed moving picture is particularly significant in telephoto.

Disclosure of Invention

The invention mainly solves the technical problem of providing a realization method for improving the view finding and shooting success rate of sports question materials, which can effectively reduce view finding errors and shooting failures when a mobile phone camera shoots a sports ground in a zooming way and improve the success rate of shooting good pictures of the sports question materials by the mobile phone.

In order to solve the technical problems, the invention adopts a technical scheme that: a realization method for improving the success rate of framing and shooting of motion subject materials is characterized in that a large-range predictive framing with a relatively short focal length is adopted for a current shot motion scene, and meanwhile, a local small-range actual shooting area picture with a relatively long focal length is shot.

The invention has the following effective effects: by using a relatively short-focus lens to predict the view field, a photographer can know the advancing direction and the moving speed of a moving object outside an actual shooting area in advance on a view frame, so that enough time is reserved for adjusting the composition in advance, and shooting is carried out after the photographed object is urgently waited to enter a proper position of the actual shooting area.
