Comment information generation device, and comment display device

摘要

A comment information generation device includes: a video input section, to which a video is input; an information input section, to which positional information is input to display a comment to track an object in the video; an initial trajectory acquisition section that acquires an initial trajectory that is a trajectory of the object corresponding to the positional information; a trajectory extending section that acquires an extended trajectory by acquiring a following trajectory that is a trajectory having a starting point after an ending point of the initial trajectory, collecting a first comment assigned in a vicinity of the initial trajectory and a second comment assigned in a vicinity of the following trajectory, and connecting the following trajectory to the initial trajectory on a basis of the first comment and the second comment; and an output section that outputs the extended trajectory as comment information.

1. A comment information generation device comprising:
a video input circuit, to which a video is input; an information input circuit, to which positional information that a user inputs is input to display a comment so as to track an object in the video; an initial trajectory acquisition circuit that acquires an initial trajectory that is a trajectory of the object corresponding to the positional information; a trajectory extending circuit that acquires an extended trajectory by acquiring a following trajectory that is a trajectory having a starting point after an ending point of the initial trajectory, collecting a first comment assigned in a vicinity of the initial trajectory and a second comment assigned in a vicinity of the following trajectory, and connecting the following trajectory to the initial trajectory on a basis of the first comment and the second comment; and an output circuit that outputs the extended trajectory as comment information.
