Embodiment Construction

[0052] (Recognition as the basis of the present invention)

[0053] With regard to the conventional review superposition method described in the "Background Art" section, the present inventors found that the following problems occurred.

[0054]The system described in Patent Document 1 is a system including a moving image server and a comment accumulation and distribution server. The playback time of , as a reference point, is superimposed on the video for distribution (hereinafter, such a video will be referred to as "commented video"). Every time a moving picture and a moving picture with a comment are distributed and reproduced, the comment newly written by the user is managed in the comment storage distribution server corresponding to the time on the time axis of the moving picture, basically regardless of the newness of the comment, In the future distribution, the distribution is performed according to the time on the time axis of the moving image. Each comment flows on...

Abstract

A comment information generation device (100) comprising: a moving image acquisition unit (101) that receives moving images; a comment input reception unit (102) that receives input of position information for objects in moving images received by the moving image acquisition unit (101) and input of comments follow-displayed on an object from a specified timing; a target time determination unit (106) that determines a target time, being a target value for the length of time that a comment is continuously displayed, on the basis of the comment received by the comment input reception unit (102); an object motion determination unit (107) that determines the movement trajectory of an object such that the movement trajectory of the object for follow-display of a comment on the object indicated by the position information is the movement trajectory for a time length sufficiently close to the target time; an output comment information generation unit (104) that generates output comment information including comments as well as movement trajectories for objects determined by the object motion determination unit (107); and an output unit (105) that outputs output comment information.

Description

technical field [0001] The present invention relates to a comment information generation device and a comment information generation method, which generate comment information for superimposing and displaying comments following an object in a moving image. Background technique [0002] In recent years, with the development of the network and the popularization of portable terminals, it has become a daily practice to easily enjoy communication with moving image content (content) and still image content with a counterpart in a remote place through the network. For example, there is a service in which, with respect to existing content, at a certain timing on the time axis of the content, users write personal preferences or viewpoints using articles, respectively. Such communication by means of content is expected to increase with the development of display devices and communication technologies in the future. [0003] Patent Document 1 discloses a technology for realizing such...
