Publication number: 20120013709Abstract: In a video signal processing circuit, when a 2D video signal is transferred in a 3D transfer format from a video signal source, a one side mute control section provided in an input video control section determines whether the 2D video signal is on the L side or on the R side of the 3D transfer format. During a period of the one side (e.g., the L side) that is not used by the 2D video signal, the one side mute control section replaces data loaded on the one side in the video signal source with fixed data, and sends it through an input video control section, a color space changing section and a packet loading section in this order. This stops these three circuit sections from operating unnecessarily, thereby reducing the power consumption.Type: ApplicationFiled: September 23, 2011Publication date: January 19, 2012Applicant: Panasonic CorporationInventor: Yuuki NISHIO

Publication number: 20120014456Abstract: In general, techniques are described for determining a vision-based quality metric for three-dimensional (3D) video. A device (12, 14) comprising a 3D analysis unit (24, 48) may implement these techniques to compute a 3D objective metric (36, 60). The 3D analysis unit (24, 48) estimates an ideal depth map (62, 70) that would generate a distortion limited image view using DIBR-based 3D video data (34) and then derives one or more distortion metrics (64, 72) based on quantitative comparison of the ideal depth map (62, 70) and a depth map (28, 58) used in the generation of the DIBR-based 3D video data (34). Based on the derived one or more distortion metrics (64, 72), the 3D analysis unit (24, 48) computes the objective metric (36, 60) to quantify visual quality of DIBR-based video data (34). The 3D objective metric (36, 60) may be used to alter or otherwise adjust depth estimation and encoding/decoding parameters to correct for expected visual discomfort.Type: ApplicationFiled: April 26, 2011Publication date: January 19, 2012Applicant: QUALCOMM IncorporatedInventors: Judit Martinez Bauza, Mashhour M.

Publication number: 20120002009Abstract: According to one embodiment, an image generator converts an input video signal to first and second divided signals to be displayed in first and second areas on one screen. First and second divided signal controllers receive the first and second divided signals, adjust the signals, and output the adjusted signals. The preparation-complete detector includes first and second frame memory groups to sequentially store a divided signal for a plurality of frames. First divided signal controller determines whether preparation to output video signals for the left and right eyes is complete or not. And First divided signal controller changes a memory selection state for reading the video signals for the left and right eyes from the first and second memory groups based on the determination indicating whether the preparation for output is complete or not complete.Type: ApplicationFiled: April 4, 2011Publication date: January 5, 2012Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Masaaki IKUTA, Koji SEKO

Publication number: 20110292170Abstract: Active Space separates the Left Frame from the Right Frame in a frame packing format. A source device is expected to transmit a constant pixel value. A sink device is expected to ignore all data received during the Active space regardless of the value. Embodiments of the present invention involve the Source device to embed intelligent information in the Active Space in lieu of the recommended fixed pixel value. Then the Sink device may read the embedded information from the Active Space, and infer the transition between the left frame and the right frame which is useful, for example, to synchronize eyewear.Type: ApplicationFiled: June 30, 2010Publication date: December 1, 2011Inventor: SUNIL K.
