Description

A smart camera method and system for a mobile terminal

technical field

  The invention relates to an intelligent photographing method, in particular to an intelligent photographing method and system for a mobile terminal.

Background technique

    Now mobile terminals such as mobile phones and tablet computers have more and more powerful camera functions, and the picture quality and pixels of shooting are constantly improving. When a user uses a mobile phone to take pictures of scenery, he often needs to click a physical button or a virtual button set on the mobile phone to achieve the purpose of taking pictures. When the user clicks the camera button, it will put pressure on the fuselage, which will easily cause the phenomenon of shaking when pressing the shutter, which will affect the shooting results and affect the shooting effect.

Contents of the invention

The technical problem to be solved by the present invention is to provide an intelligent photographing method and system for a mobile terminal. The mobile terminal obtains the moving state of the focus of the photographer's eyes by capturing, thereby automatically completing the photographing function without pressing the photographing button, which is effective. Prevent shaking and improve photo quality.

In order to solve the above-mentioned technical problems, an object of the present invention is to provide a method for intelligently taking pictures of a mobile terminal, the method comprising the following steps:

An intelligent photographing method for a mobile terminal, the method is based on a mobile terminal with a front camera and a rear camera, comprising the following steps:

Enter the shooting operation, and the rear camera will focus on the scene;

Lock after framing and focusing;

The front camera captures the photographer's eyes;

Detect the focus of the eye. If it detects that the focus of the eye has moved, it will automatically shoot and complete the shooting operation; if the focus of the eye does not move, it will maintain the current focus state.

After the framing and focusing are completed, a moving arrow mark appears on the screen interface.

When detecting the focus of the eyes, it is judged whether the focus of the eyes moves along the track of the arrow mark;

If it is, it will automatically shoot and complete the shooting operation; if not, it will maintain the current focus state.

The arrow mark moves along the central axis of the shooting interface. If the horizontal screen is taken, the arrow mark moves from left to right or from right to left; if the vertical screen is shot, the arrow mark moves from top to bottom or from bottom to top.

After the focusing is completed, the current screen is locked, and a feedback sound for completing the focusing is issued.

Another object of the present invention is to provide an intelligent photographing system for a mobile terminal, which includes a capture unit, enabling the front camera to capture the photographer's eyes; an eye movement detection unit, used to detect the moving state of the focus of the photographer's eyes, and a capture unit, For performing automatic shooting operations.

The system also includes an action unit, and causes the arrow symbol to move within the screen interface;

The judging unit is used for judging whether the eye focus moves along the moving track of the arrow mark.

Utilizing the method and system disclosed in the present invention, the mobile terminal captures the moving state of the focus of the photographer's eyes, and checks whether the focus of the eyes moves with the movement of the arrow mark to realize the function of automatically taking pictures without the need for the photographer to press the relevant buttons, effectively avoiding The jitter phenomenon caused by pressing the button can effectively prevent the jitter problem and improve the quality of the photo.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings.

A technical problem to be solved by the present invention is to provide an intelligent photographing system for a mobile terminal. First, the mobile terminal has a front camera and a rear camera. As shown in Figure 2, the system includes a capture unit, an eye movement detection unit, shooting unit, action unit and judgment unit.

The capture unit enables the front camera to capture the eyes of the photographer, and captures the eyes of the photographer in real time during the process of taking pictures, especially after focusing on the scene. The eye movement detection unit is used to detect the moving state of the photographer's eye focus, and check whether the eye focus is moving. The shooting unit automatically completes the shooting operation after detecting that the focus of the photographer's eyes has moved. The action unit, when the focus is completed, an arrow mark will appear on the screen interface, and the action unit will make the arrow mark move in the screen interface according to a certain track. For example, when the mobile terminal is shooting scenery with a horizontal screen, it can move from left to right or from right to left, and the moving track is generally a straight line track. Of course, curves or regular graphics (such as triangles, rectangles, etc.) can also be moved cyclically. Or when the mobile terminal is shooting a scene with a vertical screen, it can move from top to bottom or from bottom to top, and the same moving track is generally set as a straight track. The judging unit is used for judging whether the focus of the eye moves along the moving track of the arrow mark, so as to ensure accurate execution of the shooting operation.

As shown in accompanying drawing 1, disclose a kind of intelligent photographing method carried out by the intelligent photographing system of mobile terminal according to the present invention, comprise the following steps:

In step S1, the mobile terminal enters the shooting operation. First, the rear camera performs framing and focusing on the scene, and then goes to step S2. The focusing method and principle are existing common knowledge, and will not be described in detail here.

Step S2, lock the current foreground object after framing and focusing, and then go to step S5. Of course, if the user re-focuses the view, the original focus frame will disappear and the focus will be re-focused.

In step S5, after the focusing is completed, the front camera captures the eyes of the photographer, and the process goes to step S6.

Step S6, detect the focus of the eye, if it is detected that the focus of the eye has moved, it will automatically shoot and complete the shooting operation; if the focus of the eye has not moved, keep the current focus state, and continue to detect whether the focus of the eye has moved.

Preferably, after the framing and focusing are completed, step S4 is further included, and a moving arrow sign appears on the screen interface. Preferably, the arrow mark moves along the central axis of the shooting interface. If the horizontal screen is shot, the arrow mark moves from left to right or from right to left; if the vertical screen is shot, the arrow mark moves from top to bottom or from bottom to top For movement, the movement trajectory of the arrow mark is usually set as a straight line, but of course it is not limited to a straight line.

To further optimize the design, in step S6, when detecting the focus of the eye, it is also specifically judged whether the focus of the eye moves along the moving track of the arrow mark; That is to say, to realize automatic shooting, the focus of the photographer's eyes must follow the moving track of the arrow mark. If the focus of the eye moves but does not follow the moving track of the arrow mark, the shooting operation will not be completed automatically.

To further optimize the design, after the focus is completed in step S2, step S3 is also included, after the focus is completed, the current screen is locked, and a feedback sound of focus completion is issued to remind the photographer that the focus has been completed, which is more user-friendly.

It should be noted that the above description is not a limitation to the technical solution of the present invention, and any obvious replacements fall within the protection scope of the present invention without departing from the inventive concept of the present invention.
