Abstract

According to one embodiment, an electronic apparatus includes an image extraction module, a display control module, and a file processing module. The image extraction module extracts face images including a plurality of face images of persons in a video obtained by playing back a video data file from each of video data files. The display control module displays a selection screen which allows a user to select one or more video data files from the video data files, and displays the extracted face images on the selection screen to lay out the face images in correspondence with the video data files. The file processing module executes a process for the one or more video data files selected on the selection screen.

Claims

1. An electronic apparatus comprising:

an image extraction module configured to extract video data files having recording times within a predetermined period from stored video data files in a storage medium and to extract face images from each of the extracted video data files, the extracted face images comprising face images of persons in video obtained by playing back the extracted video data files;

a display control module configured to display a selection screen configured to enable a user to select amongst the extracted video data files, to display the extracted face images on the selection screen to be selectable by laying out the extracted face images for each of the extracted video data files, and, when the face images are selected, to select video data files comprising the selected face images; and

a file processing module configured to perform a process of merging the video data files selected on the selection screen in accordance with an order of recording times.

2. The electronic apparatus of claim 1, wherein

the image extraction module is configured to classify the face images across the extracted video data files, and to assign an identifier to face images classified as an identical person, and

the file processing module is configured to detect an identifier assigned to a face image when the face image is selected, and to process a video data file comprising the selected face image and video data files comprising other face images assigned the detected identifier in accordance with an order of recording times of the video data files.

3. The electronic apparatus of claim 2, wherein the display control module is configured to display the face images assigned an identifier of the selected face image distinctly from face images not assigned the identifier.

4. The electronic apparatus of claim 1, wherein the image extraction module is configured to extract at least one video frame as a representative image for each of the extracted video data files from which face images are extracted, and

the display control module is configured to display the representative image corresponding to each of the extracted video data files on the selection screen.

5. A video processing method comprising:

extracting video data files having recording times within a predetermined period from stored video data files in a storage medium, and extracting face images from each of the extracted video data files, the face images comprising face images of persons in video obtained by playing back the extracted video data files;

displaying a selection screen configured to enable a user to select amongst the extracted video data files, displaying the extracted face images on the selection screen to be selectable by laying out the extracted face images for each of the extracted video data files, and, when face images are selected, selecting video data files comprising the selected face images; and

performing a process of merging the video data files selected on the selection screen in accordance with an order of recording times.
