[0063] figure 1 It is a flow chart of a method for synthesizing photos according to an exemplary embodiment; the method for synthesizing photos can be applied to cameras or electronic devices (such as smart phones and tablet computers) including camera devices, such as figure 1 As shown, the photo synthesis method includes the following steps:

[0064] In step 101, the expression score value of each face in each original photo is calculated.

[0065] In an embodiment, the expression score value of each face can be measured by the face's eyes, mouth, face orientation, face image quality, and so on.

[0066] In an embodiment, after each original photo is generated, a preset image processing algorithm may be used to calculate the facial expression score value.

[0067] In one embodiment, the process of calculating the facial expression scoring value can be found in image 3 The illustrated embodiment will not be described in detail here.

[0068] In step 102, a face whose exp...

Abstract

The present invention relates to a photo composing method and apparatus. The method comprises the steps of calculating an expression score of each human face in each original picture; determining human faces with the expression scores meeting a preset condition in each original picture as human faces for generating a composed picture, wherein the preset condition refers to that the expression score is greater than a preset score threshold or less than the preset score threshold and is the highest expression score of all original pictures; determining fewest target original pictures generating the composed picture according to each human face for generating the composed picture in each original picture; and splicing human faces for generating the composed picture in the target original pictures so as to generate the composed picture. Through adoption of the photo composing method and apparatus, the better composed picture can be generated, further, the quantity of original pictures for generating the composed picture is reduced effectively, the time for generating the composed picture is shortened effectively, and the power consumption for generating the composed picture is lowered.

Description

technical field [0001] The present disclosure relates to the technical field of intelligent camera technology, and in particular, to a photo synthesis method and device. Background technique [0002] With the development of camera technology, more and more users like to take group photos to record their daily trips or friends gathering, but it is more difficult to take a group photo with better expression effects on each face. In related technologies, the camera device can perform the co-shooting optimization operation to score the faces in each generated original photo during the co-shooting process, and extract the face with the best effect for each person in all the original photos out for synthesis. In the related art, many original photos need to be synthesized when generating a composite photo, which increases the power consumption of the camera device and the time for generating the composite photo. Contents of the invention [0003] In order to overcome the probl...
