摘要： The present invention provides a method of generating a virtual viewpoint video image when the virtual viewpoint position is not located on a plane where a camera is disposed. In an environment in which a plurality of cameras having a horizontal optical axis are disposed in a real zone (for example, on the circumference) which surrounds an object, a video image of an arbitrary viewpoint on the circumference is generated. Further, by synthesizing video images photographed by a camera, a free viewpoint video image is generated from a virtual viewpoint (viewpoint from a high or low position) where no camera is placed. According to a method of achieving this, a travel distance of a display position is calculated by the local region synthesizing portion and this travel distance is reflected to the free viewpoint video image of a local region.

摘要： A feature amount extracting unit extracts a block distortion degree of an evaluated video y relative to an original video x, a PSNR overall temporal fluctuation degree, and a PSNR local temporal fluctuation degree as feature amounts. A weighted sum calculating unit calculates a weighted sum of these feature amounts, and calculates an objective video quality index. Frame rate detecting unit detects frame rate of the evaluated video y. A correcting unit corrects the objective video quality index based on the frame rate detected by the frame rate detecting unit. An objective evaluation index-subjective video quality mapping unit applies the corrected objective video quality index Qobj to a correlation between an objective video quality index and a subjective video quality given in advance, thereby deriving a subjective video quality estimated value DMOS.

摘要： A plurality of cameras is placed so that those optical axes become parallel to the Z-axis and are in relative position t on the XY plane. Multi-view video compression coding apparatus determines depth distance Z and unit normal vector (nx, ny, nz) of the arbitrary point in the surface of the object, moves the first block by disparity vector based on t and Z, transforming the first block by linear transformation matrix based on t, Z and n, then, matching the first block to block of the second picture. Then, while changing Z and n arbitrarily, the second block of the second picture which is most similar to the first block is searched for. And the apparatus derives a prediction error between the first block and the second block, codes the prediction error, and adds Z and n to coded data.

摘要： The sound acquisition apparatus broadcasts a sound “output notice request” through a communication network. In response to the request by the sound acquisition apparatus, the sound output apparatus gives notification of starting a sound output operation, the sound acquisition apparatus requests the sound output apparatus to transfer “output sound data”. The sound output apparatus then transfers “output sound data” representing the sound outputted by its own speaker to the sound acquisition apparatus in response to this request. The sound acquisition apparatus then suppresses a noise component from sound data acquired through a microphone using the transferred “output sound data”.

摘要： In a wireless communication terminal, information from a wireless communication unit is decoded by a communication control unit and analysis information is acquired. A content reception judgment unit instructs the communication control unit to terminate a content receiving process if a mobile radio environment corresponding to transmission rate information of the contents, included in the analysis information, is below a content reception threshold stored in a content reception threshold storage unit. Thus, the wireless communication terminal can judge that the possibility of a failed reception is high before content reception, and needless power consumption can be prevented and power consumption reduced by not performing reception.
