    摘要: According to one embodiment, an electronic apparatus includes a grouping module, an attribute determination module, a grouping attribute setting module, a group selection module, and a video generating module. The grouping module classifies contents, to which time information is added, into groups based on the time information. The attribute determination module determines attributes of each of the contents by analyzing features of the contents. The grouping attribute setting module sets, with respect to each of the groups, selected attributes as grouping attributes for the group, the selected attributes being selected from the attributes of the contents in the group under a predetermined condition. The group selection module selects, from the groups, at least one group for which the grouping attribute agreeing with or relating to an input search key are set. The video generating module generates video data by using the contents in the selected groups.
