Video data processing apparatus utilizing viewer influence, picture reproducing apparatus, and computer programs related thereto
View Patent ↗Every prescribed unit of video data is analyzed to estimate a degree of influence of pictures represented by every prescribed unit of video data on a viewer. For example, every prescribed unit of three-dimensional video data is analyzed to estimate a degree of influence of a depth in three-dimensional pictures represented by every prescribed unit of three-dimensional video data on a viewer. Information is generated which represents the estimated influence degree. Every prescribed unit of video data and the generated information are outputted while they are related to each other.
1. A picture reproducing apparatus comprising:
first means for reproducing three-dimensional video data having divided units each representing pictures and each including contents biological influence level information and depth information which have been compressed by run length encoding, wherein specified units among the divided units are assigned to a same playback timing, and the contents biological influence level information in each divided unit indicates an estimated level of influence of video contents in said divided unit on a biological body and the depth information in each divided unit determines an actual degree of influence of a depth in the pictures represented by said divided unit on a viewer;
second means for detecting the contents biological influence level information in each divided unit;
third means for obtaining an estimated degree of influence of the depth in the pictures represented by each divided unit on the viewer from the contents biological influence level information detected by the second means;
fourth means for setting an allowable range with respect to the estimated influence degree obtained by the third means;
fifth means for deciding whether the estimated influence degree obtained by the third means is within or outside the allowable range set by the fourth means; and
sixth means for controlling the depth information in a divided unit to reduce the actual degree of influence of the depth in the pictures represented by said divided unit on the viewer when the fifth means decides that the estimated influence degree is outside the allowable range for said divided unit.
2. A non-transitory program stored in computer-readable store means, for enabling a computer to implement a method comprising the steps of:
controlling a data reproducer to reproduce three-dimensional video data having divided units each representing pictures and each including contents biological influence level information and depth information which have been compressed by run length encoding, wherein specified units among the divided units are assigned to a same playback timing, and the contents biological influence level information in each divided unit indicates an estimated level of influence of video contents in said divided unit on a biological body and the depth information in each divided unit determines an actual degree of influence of a depth in the pictures represented by said divided unit on a viewer;
detecting the contents biological influence level information in each divided unit;
obtaining an estimated degree of influence of the depth in the pictures represented by each divided unit on the viewer from the detected contents biological influence level information;
setting an allowable range with respect to the estimated influence degree on the basis of viewer-related information inputted via user interface means;
deciding whether the estimated influence degree is within or outside the allowable range; and
controlling the depth information in a divided unit to reduce the actual degree of influence of the depth in the pictures represented by said divided unit on the viewer when it is decided that the estimated influence degree is outside the allowable range for said divided unit.
3. A method of reproducing pictures via a display device, comprising the steps of:
controlling a data reproducer to reproduce three-dimensional video data having divided units each representing pictures and each including contents biological influence level information and depth information which have been compressed by run length encoding, wherein specified units among the divided units are assigned to a same playback timing, and the contents biological influence level information in each divided unit indicates an estimated level of influence of video contents in said divided unit on a biological body and the depth information in each divided unit determines an actual degree of influence of a depth in the pictures represented by said divided unit on a viewer;
detecting the contents biological influence level information in each divided unit;
obtaining an estimated degree of influence of the depth in the pictures represented by each divided unit on the viewer from the detected contents biological influence level information;
setting an allowable range with respect to the estimated influence degree on the basis of viewer-related information inputted via user interface means;
deciding whether the estimated influence degree is within or outside the allowable range; and
controlling the depth information in a divided unit to reduce the actual degree of influence of the depth in the pictures represented by said divided unit on the viewer when it is decided that the estimated influence degree is outside the allowable range for said divided unit.
