Abstract
A cut point detection unit segments a frame sequence including successive frames into one or more subframe sequences. A face discrimination unit identifies an image group in which an object registered in advance appears, of images of respective frames that form one subframe sequence, and a representative frame candidate extraction unit selects one image from the identified image group as a selection image. A representative frame display control unit controls a display unit to display selection images for respective subframe sequences as representative images of the frame sequence.
Claims6
An image processing apparatus comprising:
- a segmentation unit which segments a frame sequence including successive frames into one or more subframe sequences;
- a selection unit which, for each of the one or more subframe sequences, identifies an image group, in which an object registered in advance appears, of images of respective frames that form one subframe sequence, and selects one image from the identified image group as a selection image;
- and
- an output unit which outputs selection images selected for respective subframe sequences by said selection unit as representative images of the frame sequence;
- wherein said selection unit selects, for respective subframe sequences, an image including a largest number of object images registered in advance of images of respective frames that form one subframe sequence as a selection image for the one subframe sequence.
An image processing method comprising:
- a segmentation step of segmenting a frame sequence including successive frames into one or more subframe sequences;
- a selection step of, for each of the one or more subframe sequences, identifying an image group, in which an object registered in advance appears, of images of respective frames that form one subframe sequence, and selecting one image from the identified image group as a selection image;
- and
- an output step of outputting selection images selected for respective subframe sequences in the selection step as representative images of the frame sequence;
- wherein said selection step selects, for respective subframe sequences, an image including a largest number of object images registered in advance of images of respective frames that form one subframe sequence as a selection image for the one subframe sequence.
A computer-readable storage medium storing a computer program for making a computer function as respective units included in an image processing apparatus which includes a segmentation unit that segments a frame sequence including successive frames into one or more subframe sequences, a selection unit that, for each of the one or more subframe sequences, identifies an image group, in which an object registered in advance appears, of images of respective frames that form one subframe sequence, and selects one image from the identified image group as a selection image;
- and an output unit which outputs selection images selected for respective subframe sequences by said selection unit as representative images of the frame sequence, said method comprising:
- a segmentation step of segmenting a frame sequence including successive frames into one or more subframe sequences;
- a selection step of, for each of the one or more subframe sequences, identifying an image group, in which an object registered in advance appears, of images of respective frames that form one subframe sequence, and selecting one image from the identified image group as a selection image;
- and
- an output step of outputting selection images selected for respective subframe sequences in the selection step as representative images of the frame sequence;
- wherein said selection step selects, for respective subframe sequences, an image including a largest number of object images registered in advance of images of respective frames that form one subframe sequence as a selection image for the one subframe sequence.
