Abstract

According to one embodiment, an electronic apparatus comprises (i) an image extraction module configured to extract representative images from a plurality of frames which constitute video content data, and to output time stamp information indicative of time points at which the extracted representative images appear, and (ii) an image list display process module configured to display a list of the extracted representative images on a two-dimensional display area. The area includes image display areas which are divided by columns, a plurality of time zones, and the image list display process module is configured to display, based on the time stamp information corresponding to each of the extracted representative images, the representative images, which belong to the time zone allocated to each column.

Claims

1. An electronic apparatus comprising:

an image extraction module configured to extract representative images from a plurality of frames which constitute video content data, and to output time stamp information indicative of time points at which the extracted representative images appear; and

an image list display process module configured to display a list of the extracted representative images on a two-dimensional display area, the two-dimensional display area includes a plurality of image display areas that are arranged in a matrix including a plurality of rows and a plurality of columns,

wherein a plurality of time zones, which are obtained by dividing a time length of the video content data by the number of the plurality of columns, are allocated to the plurality of columns, and

wherein the image list display process module is configured to display, based on the time stamp information corresponding to each of the extracted representative images, one or more extracted representative images that belong to each time zone allocated to a corresponding column of the plurality of columns on the image display areas of the column by arranging the representative images in an order of time of appearance of the representative images.

2. The electronic apparatus of claim 1 wherein the image extraction module is configured to extract face images of persons from the plurality of frames which constitute video content data, as the representative images.

3. The electronic apparatus of claim 1, wherein the image list display process module is configured to select, based on the time stamp information corresponding to each of the extracted representative images, the same number of representative images as the number of rows from the representative images which belong to the time zone allocated to the column that is an object of a display process, and to display the same number of selected representative images as the number of rows on the image display areas in the column that is the object of the display process, by arranging the representative images in the order of time of appearance of the representative images.

4. The electronic apparatus of claim 3, wherein in a case where the number of representative images belonging to the time zone, which is allocated to the column that is the object of the display process, is larger than the number of rows, the image list display process module preferentially selects, from the representative images belonging to the time zone allocated to the column that is the object of the display process, representative images with high frequency of appearance in this time zone.

5. The electronic apparatus of claim 3, wherein in a case where the number of representative images belonging to the time zone, which is allocated to the column that is the object of the display process, is larger than the number of rows, the image list display process module preferentially selects, from the representative images belonging to the time zone allocated to the column that is the object of the display process, representative images with a large size.

6. The electronic apparatus of claim 1, wherein when an event of instructing a change of a size of each of the image display areas is input, the image list display process module varies the number of rows and the number of columns included in the two-dimensional display area in accordance with a changed size that is designated by the event, and varies the time zones that are allocated to the columns included in the two-dimensional display area based on the total time length of the video content data and the varied number of columns.

7. The electronic apparatus of claim 1, wherein the image list display process module displays a plurality of thumbnail images, which correspond to a plurality of frames extracted from the video content data at equal time intervals, on a thumbnail display area which is disposed on an upper side or a lower side of the two-dimensional display area, by arranging the thumbnail images in line, and selects, in a case where a certain thumbnail image on the thumbnail display area is designated by a user, that one of the plurality of columns in the two-dimensional display area, to which the time zone to which the designated thumbnail image belongs is allocated.

8. The electronic apparatus of claim 1, further comprising a playback process module configured to start, when an invent of instructing playback of the video content data is input in a state in which one of the representative images displayed on the two-dimensional display area is selected, playback of the video content data, based on the time stamp information of the selected representative image, from a time point which is a predetermined time before a time point at which the selected representative image appears.

9. An image display method of displaying a list of images of appearing in video content data, comprising:

performing an image extraction process of extracting representative images from a plurality of frames which constitute the video content data and outputting time stamp information indicative of time points at which the extracted representative images appear; and

performing an image list display process of displaying a list of representative images, which appears in the video content data, on a two-dimensional display area by using the representative images extracted by the image extraction process, the two-dimensional display area includes a plurality of image display areas that are arranged in a matrix including a plurality of rows and a plurality of columns,

wherein a plurality of time zones, which are obtained by dividing a time length of the video content data by the number of the plurality of columns, are allocated to the plurality of columns, respectively, and

the image list display process displays, based on the time stamp information corresponding to each of the extracted representative images, the representative images, which belong to the time zone allocated to each column, on the image display areas of each column, by arranging the representative images in an order of time of appearance of the representative images.

10. The image display method of claim 9, wherein the image extraction process including extracting face images of persons from the plurality of frames which constitute video content data, as the representative images.

11. A computer-readable, non-transitory storage medium having stored thereon a program which is executable by a computer, the program controlling the computer to execute functions of:

performing an image extraction process of extracting representative images from a plurality of frames which constitute the video content data and outputting time stamp information indicative of time points at which the extracted representative images appear; and

performing an image list display process of displaying a list of representative images, which appears in the video content data, on a two-dimensional display area by using the representative images extracted by the image extraction process, the two-dimensional display area includes a plurality of image display areas that are arranged in a matrix including a plurality of rows and a plurality of columns,

wherein a plurality of time zones, which are obtained by dividing a time length of the video content data by the number of the plurality of columns, are allocated to the plurality of columns, respectively, and

the image list display process displays, based on the time stamp information corresponding to each of the extracted representative images, the representative images, which belong to the time zone allocated to each column, on the image display areas of each column, by arranging the representative images in an order of time of appearance of the representative images.

12. The computer-readable, non-transitory storage medium of claim 11, wherein the image extraction process including extracting face images of persons from the plurality of frames which constitute video content data, as the representative images.
