Compared with prior art, the preview composition of taking pictures provided by the invention based on mobile terminal instructs the embodiment of the present invention Method and system can produce composition by database analysis according to the actual conditions of photo and instruct, user to be prompted to take more Meet personal habits or the more photo of aesthetic feeling.The display of composition guidance simultaneously is succinct, clear, there is quickly and accurately suggesting effect.

Description of the drawings

Fig. 1 is the preview composition guidance method flow chart of taking pictures the present invention is based on mobile terminal;

Fig. 2 is image information schematic diagram in view-finder in the embodiment of the present invention;

Fig. 3 is image information two dimensional gray figure of the present invention.

Fig. 4, which is that the present invention is based on the preview compositions of taking pictures of mobile terminal, to instruct system principle diagram.

Specific embodiment

In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and It is not used in the restriction present invention.

Refering to Figure 1, the present invention is based on the preview composition guidance method of taking pictures of mobile terminal, including:

Step 101:Into take pictures preview mode when, the image information in the current view-finder of acquisition for mobile terminal, such as Fig. 2 institutes Show;

Specifically, opening the camera function of mobile terminal, composition guiding function menu, the underlying task of mobile terminal are selected After process scanning is chosen to composition guiding function menu, the selection operation is parsed.

Further, it is main reference object that user, which can select the arbitrary things in view-finder,.

Step 102:The mobile terminal sends the structure according to the related pattern data of image information generation got Diagram data is to cloud server;

Specifically, mobile terminal by image information (including:The size of current shooting object, present position, environmental concerns Deng) gray-scale map of two dimension is converted into, as shown in figure 3, the contour line of extraction image information.The extraction of the contour line can be logical Traversal pixel is crossed, determines whether the RGB differences between multiple adjacent pixels reach predetermined threshold value, multiple phase is determined if reaching Adjacent pixel is to form the pixel of contour line.

Step 103:Cloud server searches for matched pattern data, and passes through calculation process, obtains optimal patterning scheme Data, and the optimal patterning scheme data are sent to mobile terminal;

Specifically, cloud server possesses a large amount of various outstanding patterned templates data, receives the structure that mobile equipment is sent It after diagram data, scans for, match and comparative analysis in the database of server beyond the clouds, calculate optimal patterning scheme. For example, when shooting picture is the scene on mountain and river, which is converted into two dimensional gray figure by mobile terminal, extraction mountain and The profile in river, wherein, which can traverse all pixels by mobile terminal, when the rgb value between adjacent pixel is poor It is clipped to up to certain threshold value, it is the pixel on profile boundary to determine the pixel.Be extracted after profile, by the information of the contour line and The above-mentioned remaining image information referred to is sent to cloud server, and cloud server (can first retrieve mountain and river by searching analysis The excellent case of composition is flowed, analysis is being patterned to the excellent case retrieved, is determining the composition contour line information of the case, The location information of object, composition ratio etc.), the best patterning scheme on mountain and river is determined with this.

Step 104:Mobile terminal shows corresponding best patterning positions prompting taking pictures in preview interface, user is according to carrying Show that adjustment position is taken pictures, generate photo.

Specifically, above-mentioned position indicating is a text message or a voice messaging.

This step further includes:After corresponding best patterning positions prompting is shown in preview interface of taking pictures, confirmation setting is provided Option, when user clicks and confirms setting, mobile terminal is prompted using the composition, is adjusted position according to prompting, is pressed camera button Complete this photographing operation.

Further, after corresponding best patterning positions prompting is shown in preview interface of taking pictures, cancellation option is provided, in user When clicking cancellation, mobile terminal does not use the composition to prompt, and presses camera button and completes this photographing operation.

Further, it if the preview size of object changes at interface of taking pictures, needs to recalculate best patterning positions Prompting.

It please refers to the preview composition of taking pictures based on mobile terminal shown in Fig. 4 and instructs system, including:

One mobile terminal,

And the cloud server of wireless connection is established with mobile terminal;
