Video reception device and image recognition method for received video
First Claim
1. A video reception device connected to an image recognition device for performing image recognition, the video reception device comprising:
- a video input unit configured to receive a video including content items switches of which occur as time elapses;
a video extraction unit configured to extract from the video a partial video which is a portion of the video, the partial video having a predetermined time length;
a content switchover detection unit configured to detect whether or not the partial video includes content switchover indicating switchover of the content items; and
a control unit configured to perform, when the content switchover detection unit detects that the partial video includes no content switchover, a control to output the partial video to the image recognition device to obtain a result of the image recognition for the partial video from the image recognition device,wherein the video extraction unit is configured to repeatedly extract a new partial video from the video,the content switchover detection unit is configured to perform the detection every time the video extraction unit extracts the partial video, andthe control unit is configured to perform the control every time the content switchover detection unit performs the detection, and when the content switchover detection unit detects that the partial video includes the content switchover, the control unit is configured to, without outputting the partial video to the image recognition device, cause the video extraction unit to extract a new partial video.

Abstract
A video reception device connected to an image recognition device for performing image recognition includes: a video input unit that receives a video including content items switches of which occur as time elapses; a video extraction unit that extracts from the video a partial video which is a portion of the video; a content switchover detection unit that detects whether or not the partial video includes content switchover indicating switchover of the content items; and a control unit that performs, when the content switchover detection unit detects that the partial video includes no content switchover, a control to output the partial video to the image recognition device to obtain a result of the image recognition for the partial video from the image recognition device.

9. An image recognition method for a video received by a video reception device connected to an image recognition device for performing image recognition, the method comprising:
-
receiving the video including content items switches of which occur as time elapses; extracting from the video a partial video which is a portion of the video, the partial video having a predetermined time length; detecting whether or not the partial video includes content switchover indicating switchover of the content items; and performing a control to output the partial video to the image recognition device to obtain a result of the image recognition for the partial video from the image recognition device when it is determined in said detecting that the partial video includes no content switchover, wherein said extracting comprises repeatedly extracting a new partial video from the video, said detecting is performed every time the partial video is extracted in said extracting, and said performing takes place every time said detecting is performed, and said performing further comprises performing a control to cause a new partial video to be extracted in said extracting without outputting the partial video to the image recognition device when it is determined in said detecting that the partial video includes the content switchover.
