Embodiment Construction

[0045] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0046] figure 1 It is a schematic diagram of the method for correcting the shooting tilt of the subject provided by the embodiment of the present invention, as shown in figure 1 As shown, the specific steps are as follows:

[0047] Step S101: After the mobile terminal detects that the subject enters the viewfinder interface, it recognizes the boundary of the subject's outline to obtain the subject's outline.

[0048] In step S101 , the color and lightness between the object and the background are compared, and the boundary of the object contour is identified to obtain the object contour.

[0049] Step S102: Analyzing the outline of the subject to determ...

Abstract

The invention discloses a method and a device for correcting photographing inclination of a photographed object and a mobile terminal, and relates to the field of mobile terminals. The method comprises the following steps: when the mobile terminal detects that the photographed object enters a framing interface, identifying the boundary of an outline of the photographed object to obtain the outline of the photographed object; analyzing the outline of the photographed object to judge whether the photographed object inclines; and if judging that the photographed object inclines, carrying out straightening photographing on the photographed object to obtain a straightened image of the photographed object. By adopting the method disclosed by the invention, the mobile terminal can correct the inclination of the image of the photographed rectangular planar object caused by a photographing angle during photographing by a built-in algorithm program method of the mobile terminal.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a method, a device and a mobile terminal for correcting the inclination of a subject due to a shooting angle when a mobile terminal takes pictures. Background technique [0002] When a user uses a mobile phone to shoot flat rectangular objects such as calligraphy and painting works, posters, documents, etc., often because the camera cannot be placed on the vertical line perpendicular to the object center point perpendicular to the object plane, the rectangular object will appear on the screen after shooting due to the perspective relationship. It is trapezoidal, which seriously affects the appearance and causes poor user experience. [0003] Currently, the camera application of mobile phone terminal products does not have the function of correcting the plane tilt of the subject due to the shooting angle. Users usually have two solutions to avoid the plane tilt of the subje...
