Detailed ways

The present invention will be further described below with reference to the accompanying drawings and preferred embodiments, but the embodiments of the present invention are not limited thereto.

The mobile phone photographing method of the present invention is suitable for photographing portraits with mobile phones. When taking pictures, the background of the characters is blurred, or after the photograph is taken, the background of the characters in the mobile phone is blurred or the background is replaced, so that it can meet the requirements without the help of a third software. The photographer blurs or replaces the background of the photo.

Referring to Fig. 1 and Fig. 2, in the first embodiment, when the mobile phone takes pictures, the background of the characters is automatically blurred, which specifically includes the following steps:

S10. Turn on the smile recognition function when taking pictures to identify the face area;

When taking a picture, the mobile phone will automatically recognize the smiling expression of the person's face, so as to obtain the face area.

S20. Centering on the recognized face area, perform background blurring outward layer by layer at a preset interval.

By taking the face area as the center and performing blurring outward layer by layer, the background other than the characters is blurred, the depth of field is increased, and the subject of the portrait is highlighted.

With reference to Fig. 3, in embodiment two, adopt the method for blurring the character background of mobile phone photo after taking a picture, specifically comprise the following steps:

S20. After taking the picture, the user draws the outline of the edge on the mobile phone;

The user can draw the edge outline along the portrait area or the required area on the touch screen of the mobile phone with a finger or a brush, and the software will automatically find the drawn edge line according to the trajectory of the finger or brush to form an edge outline.

S21. Perform background blurring on areas outside the drawn edge outline.

The software adjusts the blur degree of the area outside the edge outline to increase the depth of field and highlight the subject of the portrait.

With reference to Fig. 4, in embodiment three, adopt the method that background replacement is carried out to the character background of mobile phone photo after taking a picture, specifically comprise the following steps:

S20. After taking the picture, the user draws the outline of the edge on the mobile phone;

S22. Perform background image replacement on areas outside the outlined edge outline.
