Abstract

An in-scene digest segment number determining unit allocates the total number of cuts to be extracted as digest segments to each scene of digest creation objective scenes. A feature quantity detecting unit selects a plurality of representative frames from respective frames included in a cut extraction scene where the number of digest segments to be extracted is one or more and further detects a feature quantity of each representative frame. An importance calculating unit calculates the degree of importance of each representative frame, based on the feature quantities of each representative frame. A digest segment selecting unit determines a digest segment to be selected from each cut extraction scene, based on both feature quantities and importance degrees of representative frames in each cut extraction scene.

Claims6

Dependent claims

An image processing device comprising:

an in-group digest segment number determining unit configured to determine the number of digest segments to be extracted from each of scenes forming image data;
a feature quantity detecting unit configured to:
select a plurality of representative frames out of frames included in a cut extraction scene where the number of digest segments determined by the in-group digest segment number determining unit is one or more;
and
detect at least one of:
the number of faces of subjects existing in each of the representative frames;
the position of a largest one of the faces in each of the representative frames;
and the size of the largest face, as a feature quantity of each of the representative frames;
a scene feature judging unit configured to judge a feature of the cut extraction scene, based on the feature quantity;
an importance calculating unit configured to calculate an importance degree of each of the representative frames based on the feature quantity with use of a calculating expression corresponding to the feature judged by the scene feature judging unit, the calculating expression being one of a plurality of predetermined calculating expressions corresponding to features of the cut extraction scene;
a digest segment selecting unit configured to select cuts of the same number as the digest segments determined by the in-group digest segment number determining unit, from the cut extraction scene, based on the feature quantity and the importance degree;
and
a reproducing unit configured to reproduce the digest segments selected by the digest segment selecting unit.
