COMMENT INFORMATION GENERATION DEVICE AND COMMENT INFORMATION GENERATION METHOD

摘要

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.
