Methods for delta-QP signaling for decoder parallelization in hevc

ActiveUS20120183049A1Color television with pulse code modulationColor television with bandwidth reductionComputer architectureCoded block flag
By implementing a new bitstream for a Delta-Quantization Parameter (DQP), a decoder is able to implement parallel decoding of multiple coding units within a largest coding unit. In some embodiments, the DQP is placed immediately after the mode information of the first coding unit. In some embodiments, the DQP is placed after the mode information of the first non-skipped coding unit. In some embodiments, the DQP is placed after the first non-zero coded block flag.

Light source device and projection display device

To provide a compact light source device with a wide color gamut capable of ensuring uniformity of projected images even when the luminous flux sizes of the red, green, and blue solid-state light sources are different.SOLUTION: The light source device includes: multiple solid-state light sources in red, green, and blue; a polarizing mirror that combines colored light from the solid-state light sources; and a plural beam splitter elements for splitting the light beam from the blue solid-state light source. The beam splitter elements are mirrors that split the blue light into approximately 50% transmission and reflection, and transmit or reflect more than 90% of green and red light. The projection display device uses the light source device.SELECTED DRAWING: Figure 1

In an example method, for a plurality of octants, residual information is obtained for one or more vertices of the respective octant, where the vertices correspond to respective points in a three-dimensional lookup table. The lookup table is decoded recursively as follows: at least a first one of the plurality of octants is decoded by reconstructing at least a first color sample value from the residual information for at least a first vertex of the first octant; and a plurality of second octants in the plurality of octants are decoded, where the second octants are obtained by splitting the first octant. A color transform is then applied based on the decoded lookup table.

Video transmission within mobile devices

Video samples from one or more cameras of a mobile device are sent as analog levels to the device's system-on-a-chip (SoC) or other processor. Analog levels are either analog video samples or an encoded form of video samples. The samples are converted to digital and interpolated within the SoC to produce digital RGB samples suitable for display. Alternatively, analog video samples are interpolated within the SoC using analog processing to produce analog RGB samples. Or, only G-sampling is sent to the SoC and processed using analog processing. After processing within the SoC, the samples are sent as analog levels or in an encoded form to the corresponding receiver of the display, which is integrated with the column driver. The digital functions of the display's DDIC are either built into the SoC or connected to separate circuitry via a MIPI DSI interface.

ActiveJP7843476B2Color signal processing circuitsPicture reproducers using cathode ray tubesImaging processingRadiology
A video processing system (2) is provided with: a first input interface (21); a second input interface (22); and a CPU (231). The first input interface (21) acquires a video signal to be outputted to a display panel (10) of a display (1). The second input interface (22) acquires color temperature information indicating the color temperature of environment light emitted toward the display panel (10). The CPU (231) calculates a correction amount of the color temperature of the video signal so as to conform to the color temperature of the environment light. The CPU (231) subtracts the absolute value of the correction amount of the color temperature of the video signal so as to cancel the color temperature of the environment light when the pixel luminance of the video signal is less than a luminance threshold value. The CPU (231) outputs the video signal having the color temperature of the video signal corrected in accordance with the correction amount.
