Title:
DELAY DETECTION DEVICE AND DELAY DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2010/137166
Kind Code:
A1
Abstract:
A delay detection device comprises a signal branch/distribution section (10) which receives input of an image signal, separates a part of the image signal, outputs the part as a first signal, and outputs the remaining part as a second signal; an output section (20) which allows the first signal outputted from the signal branch/distribution section (10) to be displayed by a display device (22) and allows the second signal outputted from the signal branch/distribution section (10) to be outputted by a voice output device (24); an image sensor (30) which detects an image displayed by the display device (22); a sound sensor (40) which detects the voice outputted from the voice output device (24); and a delay detection section (60) which detects, on the basis of the detected result of the image sensor (30) and that of the sound sensor (40), the difference between reproduction timings of a signal obtained by the image sensor (30) and that obtained by the sound sensor (40).
