When the depth of view information of the first image changes compared to the depth of view information of any one preview image frame, then Target image is generated according to each preview image frame.

6. a kind of mobile terminal, which is characterized in that the mobile terminal includes:

Acquisition module, for before carrying out image taking, calling the preview image frame of the 3D camera acquisition preset quantity；

Determining module for calling the 3D camera to shoot the first image according to shooting instruction, and determines the first image The wobble information of image information and the mobile terminal in shooting process；

Generation module, for when the wobble information of described image information and/or the mobile terminal meets preset condition, foundation Each preview image frame generates target image.

7. mobile terminal according to claim 1, which is characterized in that the wobble information of the mobile terminal includes the shifting The displacement and angle change value of dynamic terminal, the generation module include:

First generates submodule, is greater than preset displacement for the displacement when the mobile terminal and the angle change value is greater than in advance If when angle value, generating target image according to each preview image frame.

8. mobile terminal according to claim 6, which is characterized in that the generation module includes:

Determine submodule, for being less than or equal to the preset displacement when the displacement, and the angle change value is less than or waits When the predetermined angle, the first weighted value of each preview image frame and the second weighted value of the first image are determined；

Second generates submodule, is used for according to first weighted value and second weighted value, by each preview image frame It is merged with the first image, generates target image.

9. mobile terminal according to claim 8, which is characterized in that the generation module includes:

Third generates submodule, for the RGB image information when the first image compared to any one preview image frame RGB image information when changing, then generate target image according to each preview image frame.

10. according to the method described in claim 8, it is characterized in that, the generation module includes:

4th generates submodule, the scape for the depth of view information when the first image compared to any one preview image frame When deeply convinceing that breath changes, then target image is generated according to each preview image frame.

11. a kind of mobile terminal, which is characterized in that including processor, memory and be stored on the memory and can be in institute The computer program run on processor is stated, such as claim 1 to 5 is realized when the computer program is executed by the processor Any one of described in image pickup method the step of.
