Moving object snapshotting method and mobile terminal

Abstract

The invention provides a moving object snapshotting method, and belongs to the technical field of mobile communication. The method is used for a mobile terminal with a camera. The method comprises the steps: obtaining a first image, taken by the camera in an automatic exposure mode, of a moving object; determining the moving speed of the moving object, and determining the shutter time corresponding to the moving speed; obtaining a second image, taken based on the shutter time, of the moving object; carrying out the synthesis of the first and second images, and obtaining a snapshot image of the moving object. The invention also provides the corresponding mobile terminal. According to the invention, the method calculates the optimal exposure time through the moving speed of the moving object, can obtain a clear image (no smear) of the moving object, and solves a problem that there is smear in a snapshot image of the quickly moving object during the snapshotting of the moving object.

Description

technical field

[0001] The invention relates to the technical field of mobile communication, in particular to a method for capturing images of moving objects and a mobile terminal. Background technique

[0002] With the increasing popularity of mobile terminals and the gradual development of mobile terminal camera technology, more and more users use mobile terminals to take pictures, such as shooting scenery, people, animals and so on. However, due to the limitation of the hardware structure of the camera and the inflexible setting of the shooting parameters of the camera when using the mobile terminal to shoot images, blurring and smearing of the captured images often occur in the process of shooting moving objects. unclear situation.

[0003] At present, in the prior art, a method of reducing the shutter time is usually adopted to solve the problem of smearing when shooting moving objects. However, the fixed shutter time is only suitable for objects moving at a normal sp...

Examples

Embodiment 1

[0028] An embodiment of the present invention provides a method for capturing a moving object, which is applied to a mobile terminal with a camera, such as figure 1 As shown, the method includes:

[0029] Step 101, acquiring a first image of a moving object captured by the camera in an automatic exposure mode.

[0030] When the user uses the mobile terminal to take pictures, he first turns on the camera and enters the photo preview mode. If the user wants to shoot a moving object, he usually enters the capture mode. In the capture mode, before the user clicks the "shoot" button, the camera captures the scene in the viewfinder in real time and displays it on the display of the mobile terminal. This mode belongs to the photo preview mode.

[0031] In order to be able to capture moving objects, mobile terminal users need to follow the movement trend of the object to be photographed, and move the mobile terminal accordingly, so that the moving object can be kept in the viewfinde...

Embodiment 2

[0042] In specific implementation, such as figure 2 As shown, the method for capturing a moving object includes: Step 201 to Step 206 .

[0043] Step 201, acquiring a first image of a moving object captured by the camera in an automatic exposure mode.

[0044] For a specific implementation solution of acquiring the first image of the moving object captured by the camera in the automatic exposure mode, refer to the relevant steps in Embodiment 1, which will not be repeated here.

[0045] Step 202, determining the moving speed of the moving object.

[0046] During specific implementation, if the mobile terminal includes a first camera and a second camera, the step of determining the moving speed of the moving object includes: acquiring the moving objects captured by the first camera and the second camera respectively The third image and the fourth image of the moving object, and the fifth image and the sixth image of the moving object collected at preset time intervals; deter...
