Electronic device and facial image display apparatus

Abstract

According to one embodiment, an electronic apparatus includes a storage device which stores face thumbnail indexing information including face images and time stamp information, extracting module configure to assign time zones to a video content data and to extract face images belonging to each time zone based on a time stamp information, classifying module configure to classify facial images of the same person from the extracted facial images, calculating module configure to calculate a frequency of appearance of each classified facial image, and facial image indication module configure to display a list of the facial images included in the facial image indexing information in a facial image indication in a two-dimensional display area, the facial image indication having time-zone-specific display areas in columns corresponding to the time zones, each facial image displayed in each time-zone-specific display area being displayed in a size based on the frequency of appearance.

1 . An electronic apparatus comprising:
 a storage device which stores face thumbnail indexing information including a plurality face images extracted from video content data and time stamp information indicative of a time point at which each facial image appears in the video content data;   extracting module configure to assign a plurality of time zones to the video content data and to extract face images belonging to each time zone based on the time stamp information;   classifying module configure to classify facial images of the same person from the extracted facial images;   calculating module configure to calculate a frequency of appearance of each classified facial image; and   facial image indication module configure to display a list of the plurality of facial images included in the facial image indexing information in a facial image indication in a two-dimensional display area, the facial image indication having time-zone-specific display areas in a plurality of columns corresponding to the plurality of time zones, each facial image displayed in each time-zone-specific display area being displayed in a size based on the frequency of appearance.   
   
   
       2 . The apparatus according to  claim 1 , further comprising an indexing processing module which extracts a plurality of facial images from the video content data and outputs the time stamp information indicating a time point at which each extracted facial image appears in the video content data. 
   
   
       3 . The apparatus according to  claim 1 , further comprising selecting module configure to select a user to specify a display format displayed in the facial image indicating area from a plurality of display formats displayed in sizes based on the frequencies of appearances. 
   
   
       4 . The apparatus according to  claim 1 , wherein, the facial image indication module enlarges and displays the one facial image or displays a scene image from which the facial image is extracted, when an event for one facial image is input in accordance with an operation by the user. 
   
   
       5 . The apparatus according to  claim 4 , further comprising setting module configure to set an operation of the user to input the event. 
   
   
       6 . The apparatus according to  claim 5 , wherein a pointer whose display position varies in accordance with an operation of the user is displayed, and
 the setting module sets a time during which the pointer remains stationary on the facial image.   
   
   
       7 . A facial image display method comprising:
 generating facial image indexing information including a plurality of facial images extracted from video content data and time stamp information indicating a time point at which each facial image appears in the video content data;   assigning a plurality of time zones to the video content data and extracting facial images belonging to each time zone based on the time stamp information;   classifying facial images of the same person from the extracted facial images belonging to the same time zone;   calculating a frequency of appearance of each classified facial image; and   displaying a list of the plurality of facial images included in the facial image indexing information in a facial image display area in a two-dimensional display area,   wherein the facial image display area has time-zone-specific display areas in a plurality of columns corresponding to the plurality of time zones, and each facial image displayed in each time-zone-specific display area is displayed in a size based on the frequency of appearance.   
   
   
       8 . The method according to  claim 7 , wherein a plurality of display formats which are displayed in sizes based on the frequencies of appearance are prepared, and the facial images are displayed in each time-zone-specific display area in accordance with the display format specified by a user. 
   
   
       9 . The method according to  claim 7 , wherein, when an event that is generated with respect to one facial image is produced in accordance with an operation of the user, the one facial image is enlarged and displayed, or a scene image from which the facial image is extracted is displayed. 
   
   
       10 . The method according to  claim 9 , wherein a pointer whose display position varies in accordance with an operation of the user is displayed, and the event is generated when a time during which the pointer remains stationary on the facial image passes a set time.
