Abstract

The invention provides a picture screening method and device and a mobile terminal. The picture screening method includes the steps that a reference picture is acquired; target picture features are exacted from the reference picture; target pictures corresponding to the target picture features are screened out. When pictures with similar themes or content are screened from a large number of pictures, firstly, a reference picture is acquired; then, target picture features are exacted from the reference picture; then, target pictures corresponding to the target picture features are screened out from the large number of pictures. Thus, the pictures comprising the target picture features are screened out from the large number of pictures, the picture screening workload is effectively reduced, and the screening efficiency and accuracy are improved.

Description

Picture screening technique and device, mobile terminal
Technical field
The present invention relates to a kind of technical field of image processing, particularly relate to a kind of picture screening technique and device, mobile terminal.
Background technology
Along with gradually becoming strong of mobile phone camera function, everybody more and more custom mobile phone take scene in life, beautiful scenery during the journey and the auto heterodyne of spare time conveniently, but the thing followed is problem that in photograph album, photo amount is excessive screens the picture wanted to us and bring very large difficulty.
In prior art; the display screen of terminal is used to check that the mode of the album picture in terminal has three kinds usually; the first is individual preview; the second is thumbnail preview; the third is then individual preview under the state of thumbnail; but, when user is when checking, screening, arrange the picture of photograph album, often such scene can be run into:
Scene one: company organization's tourism shooting group picture or student graduate season shooting group picture, and several cameras are taken pictures together, finally the photo of all different cameral is pooled to a picture library photograph album and carries out contrast and screen, now photo fall into disarray and content is close.
Scene two: schoolgirl will from numerous auto heterodynes, selects one and favoritely works as head portrait, screen finally several time be difficult to accept or reject, need ceaselessly to contrast to leaf through, and the position of these photos in photograph album is arbitrarily and dispersion.
In these scenes above-mentioned, when user screens photo in terminal photograph album, following scheme is usually adopted to carry out picture screening operation: 1. select one to contrast photo from photograph album shrinkage figure, click large figure preview; 2. turn back to picture shrinkage interface; 3. choose second to contrast photo, click large figure preview; 4. brain contrasts the memory that last figure stays; 5. retain a certain pictures wherein.
Therefore, adopt such scheme, individual preview to picture to be selected can only be realized, and picture to be selected can not be shown simultaneously, when needs picture deleted, replace, the operation such as reservation time, operation steps is comparatively loaded down with trivial details, especially when picture amount is larger, need repeatedly to browse picture to be selected, have impact on the efficiency that user screens picture, reduce Consumer's Experience.
And in order to be shown picture to be selected simultaneously, user needs in advance by photo classification, add the workload of user, screening effeciency is low.
