Abstract

Provided is a view quality judging device capable of accurately judging the view quality without posing a load on a viewer. The view quality judging device is used in view quality data generation device (100), which includes an expected feeling value information generation unit (300) for acquiring expected feeling value information indicating feeling expected to be generated in a viewer who vies a content; a feeling information generation unit (200) for acquiring feeling information indicating the feeling generated in the viewer upon viewing the content; and a view quality data generation unit (400) for judging the view quality of the content by comparing the expected feeling value information to the feeling information.

Claims

1. A audience quality judging apparatus comprising:

an expected emotion value information acquisition section that acquires expected emotion value information indicating an emotion expected to occur in a viewer who views content;

an emotion information acquisition section that acquires emotion information indicating an emotion that occurs in a viewer when viewing the content; and

a audience quality judgment section that judges audience quality of the content by comparing the emotion information with the expected emotion value information.

2. The audience quality judging apparatus according to claim 1, wherein the audience quality judgment section executes the comparison on respective time-divided portions of the content and judges the audience quality from a plurality of comparison results.

3. The audience quality judging apparatus according to claim 1, further comprising:

a content acquisition section that acquires the content; and

an expected emotion value information table in which a type of editing contents of the content and the expected emotion value information are associated in advance,

wherein the expected emotion value information acquisition section determines a type of editing contents of the acquired content and acquires the expected emotion value information by referencing the expected emotion value information table.

4. The audience quality judging apparatus according to claim 1, further comprising a sensing section that acquires biological information of the viewer,

wherein the emotion information acquisition section acquires the emotion information from the biological information.

5. The audience quality judging apparatus according to claim 1, wherein:

the expected emotion value information includes an expected emotion occurrence time indicating an occurrence time of the emotion expected to occur, and an expected emotion value indicating a type of the emotion expected to occur;

the emotion information includes an emotion occurrence time indicating an occurrence time of an emotion that occurs in the viewer, and a measured emotion value indicating a type of an emotion that occurs in the viewer; and

the audience quality judgment section comprises;

a time matching judgment section that judges presence or absence of time matching whereby the expected emotion occurrence time and the emotion occurrence time are synchronous;

an emotion matching judgment section that judges presence or absence of emotion matching whereby the expected emotion value and the measured emotion value are similar; and

an integral judgment section that judges the audience quality by integrating presence or absence of the time matching and presence or absence of the emotion matching.

6. The audience quality judging apparatus according to claim 5, wherein the integral judgment section judges that the viewer viewed with interest when the time matching and the emotion matching are both present, and judges that the viewer did not view with interest when the time matching and the emotion matching are both absent.

7. The audience quality judging apparatus according to claim 6, wherein the integral judgment section judges that whether or not the viewer viewed with interest is unknown when one of the time matching and emotion matching is present and the other is absent.

8. The audience quality judging apparatus according to claim 6, wherein:

the time matching judgment section judges presence or absence of the time matching per unit time for the content;

the emotion matching judgment section judges presence or absence of the emotion matching per unit time for the content; and

the integral judgment section determines the audience quality from judgment results of the time matching judgment section and the emotion matching judgment section.

9. The audience quality judging apparatus according to claim 8, wherein the integral judgment section, for a portion in which the time matching is present and the emotion matching is absent within the content, judges that the viewer viewed with interest when the time matching is present in another portion of the content, and judges that the viewer did not view with interest when the time matching is absent in the other portion.

10. The audience quality judging apparatus according to claim 8, wherein the integral judgment section, for a portion in which the time matching is absent and the emotion matching is present within the content, judges that the viewer viewed with interest when the emotion matching is present in another portion of the content, and judges that the viewer did not view with interest when the emotion matching is absent in the other portion.

11. The audience quality judging apparatus according to claim 5, wherein:

the content includes an image;

the audience quality judging apparatus further comprises;

a line of sight direction detecting section that detects a line of sight direction of the viewer; and

a line of sight matching judgment section that judges presence or absence of line of sight matching whereby the line of sight direction is toward an image included in the content; and

the integral judgment section judges the audience quality by integrating presence or absence of the time matching, presence or absence of the emotion matching, and presence or absence of the line of sight matching.

12. The audience quality judging apparatus according to claim 3, wherein:

the content is video content that includes at least one of music, a sound effect, a video shot, and camerawork;

the expected emotion value information table associates in advance the expected emotion value information with respective types for music, a sound effect, a video shot, and camerawork; and

the expected emotion value information acquisition section determines a type of an item included in the content among music, a sound effect, a video shot, and camerawork, and acquires the expected emotion value information by referencing the expected emotion value information table
