Method and apparatus for correcting tilt of subject ocuured in photographing, mobile terminal, and storage medium

An apparatus for correcting a tilt of a subject occurred in photographing, comprising a processor configured to:

• identify, in response to detecting, by a mobile terminal, the subject entering a viewfinder interface displayed on the mobile terminal, a boundary of a profile of the subject to obtain the profile of the subject;
• analyze the profile of the subject to determine whether the subject is tilted;
• and
• perform straightening and photographing on the subject to obtain a picture in which the subject is straightened in response to determining that the subject is tilted;
• obtain, after performing a first operation on the subject in response to determining to perform straightening and photographing, a picture in which the subject is tilted according to a received photographing instruction;
• and
• perform a second operation on the picture in which the subject is tilted and obtain the picture in which the subject is straightened;
• wherein the processor is configured to perform the first operation on the subject in response to determining to perform straightening and photographing by:
• providing auxiliary lines, wherein the auxiliary lines are perpendicular to a longer side in the parallel sides of the profile of the subject, and the auxiliary lines pass through two corner points of the longer side in the parallel sides respectively;
• and
• providing arrows, wherein the arrows are directed to the auxiliary lines from two corner points of a shorter side in the parallel sides of the profile of the subject respectively, and are indicative of movement directions of the two corner points of the shorter side in the parallel sides.

A mobile terminal, comprising a camera and a processor,

• wherein the processor is configured to:
• identify, in response to detecting, by the processor, a subject entering a viewfinder interface of the camera, a boundary of a profile of the subject to obtain the profile of the subject;
• to analyze the profile of the subject to determine whether the subject is tilted;
• perform straightening and photographing on the subject to obtain a picture in which the subject is straightened in response to determining that the subject is tilted;
• obtain, after performing a first operation on the subject in response to determining to perform straightening and photographing, a picture in which the subject is tilted according to a received photographing instruction;
• and perform a second operation on the picture in which the subject is tilted and obtain the picture in which the subject is straightened;
• wherein the processor is further configured to perform the first operation on the subject in response to determining to perform straightening and photographing by:
• providing auxiliary lines, wherein the auxiliary lines are perpendicular to a longer side in the parallel sides of the profile of the subject, and the auxiliary lines pass through two corner points of the longer side in the parallel sides respectively;
• and
• providing arrows, wherein the arrows are directed to the auxiliary lines from two corner points of a shorter side in the parallel sides of the profile of the subject respectively, and are indicative of movement directions of the two corner points of the shorter side in the parallel sides.
