Problems solved by technology

When shooting with a mobile phone, only the imaging of the object can be seen on the preview interface, but the size ratio of the object in the preview interface to the actual object cannot be known, so there is no intuitive understanding when taking photos, and in some scenes It is necessary to know the size ratio of the photo to the actual object. Obviously, the shooting preview method in the prior art cannot meet the demand

Abstract

The invention relates to a shooting preview method and system. The method includes the following steps: obtaining the distance between a lens of a shooting device and a shot object, and obtaining a focal length after the shooting device completes focus; determining an image distance according to the distance between the lens of the shooting device and the shot object and the focal length, the image distance being the distance between an image of the shot object and the lens; obtaining a zoom ratio of a photo of the shot object currently displayed in a preview interface of the shooting device; and determining actual ratio information of the photo and the shot object according to the zoom ratio, the image distance, and the distance between the lens of the shooting device and the shot object, and displaying the actual ratio information in the preview interface. The shooting preview method and system can effectively assist the shooting. A user can properly change the distance between the lens and the shot object according to the actual ratio information displayed in the preview interface and shoot the photo of which the size ratio with the actual object satisfies a requirement.

Description

technical field [0001] The invention relates to the technical field of shooting, in particular to a shooting preview method and system. Background technique [0002] With the development of mobile communication technology, mobile phones are widely used in daily life, and the functions of mobile phones are becoming more and more abundant. At present, most smartphones have the function of taking pictures. When shooting with a mobile phone, only the imaging of the object can be seen on the preview interface, but the size ratio of the object in the preview interface to the actual object cannot be known, so there is no intuitive understanding when taking photos, and in some scenes It is necessary to know the size ratio of the photo to the actual object, and obviously the shooting preview method in the prior art cannot meet the demand. Contents of the invention [0003] Based on this, in order to solve the problems in the prior art, the present invention provides a shooting pr...
