Video display device, television receiver, transmitting device, control program, and recording medium
A technology of preventing feeling of a viewer on brightness from significantly changing when content is switched is provided. A video display device ( 1 ) includes a calculation unit ( 23 ) that calculates video feature relating to a display video, and a mute video display unit that displays a mute video posterior to a first display video, in which luminance of the mute video is luminance corresponding to a value of the video feature relating to the first display video.
1. A video display device comprising:
a calculation unit that calculates video feature relating to a display video; and
a mute video display unit that displays a mute video posterior to a first display video,
wherein luminance of the mute video is luminance corresponding to a value of the video feature relating to the first display video,
wherein the mute video display unit displays the mute video prior to a second display video,
wherein the video display device includes an acquisition unit that acquires a video feature relating to the second display video from meta information relating to the display video, and
wherein the luminance of the mute video is luminance corresponding to values of the video features relating to the first display video and the second display video.
2. The video display device according to claim 1 ,
wherein the calculation unit calculates a video feature within a predetermined period of the display video, and
wherein the luminance of the mute video is luminance corresponding to the value of the video feature within the predetermined period of the first display video and the value of the video feature within the predetermined period of the second display video.
3. The video display device according to claim 1 ,
wherein the video feature is a sense luminance value.
4. The video display device according to claim 3 ,
wherein the calculation unit calculates the sense luminance value with reference to at least one of an average luminance, a maximum luminance, a median value of the luminance value, and MaxFALL of the display video.
5. The video display device according to claim 1 ,
wherein the calculation unit calculates the sense luminance value by excluding at least one of a screen having an average luminance less than or equal to a first threshold value and a screen having an average luminance greater than or equal to a second threshold value, among the display videos.
6. A television receiver comprising:
the video display device according to claim 1 .
7. A non-transitory computer readable recording medium comprising:
the control program that causes a computer to function as the video display device according to claim 1 .
8. A video display device comprising:
an acquisition unit that acquires video features of one or a plurality of contents from meta information on a display video; and
a mute video display unit that displays a mute video posterior to a first display video and prior to a second display video,
wherein luminance of the mute video is luminance corresponding to a value of a video feature relating to the first display video and a value of a video feature relating to the second display video.
9. The video display device according to claim 8 ,
wherein the acquisition unit acquires a video feature within a predetermined period of the first display video and a video feature within a predetermined period of the second display video, and
wherein the luminance of the mute video is luminance corresponding to a value of a video feature within a predetermined period of the first display video and a value of a video feature within a predetermined period of the second display video.
10. The video display device according to claim 8 ,
wherein the acquisition unit acquires video features of one or a plurality of contents from a video component descriptor that is included in an MMT package table which is meta information on the display video.
11. The video display device according to claim 8 ,
wherein the acquisition unit acquires video features of one or a plurality of contents from an event information table that is meta information on the display video.
12. A non-transitory computer readable recording medium comprising:
the control program that causes a computer to function as the video display device according to claim 8 .
13. A television receiver comprising:
the video display device according to claim 8 .
14. A method of displaying a video, comprising:
a calculation step that calculates video feature relating to a display video; and
a mute video display step of displaying a mute video posterior to a first display video,
wherein luminance of the mute video is luminance corresponding to a value of the video feature relating to the first display video,
wherein the mute video display step displays the mute video prior to a second display video,
wherein the method of displaying the video includes an acquisition step of acquiring a video feature relating to the second display video from meta information relating to the display video, and
wherein the luminance of the mute video is luminance corresponding to values of the video features relating to the first display video and the second display video.
15. A method of displaying a video, comprising:
an acquisition step of acquiring video features of one or a plurality of contents from meta information on a display video; and
a mute video display step of displaying a mute video posterior to a first display video and prior to a second display video,
wherein luminance of the mute video is luminance corresponding to a value of a video feature relating to the first display video and a value of a video feature relating to the second display video.
