The present invention relates to methods or system for the measurement of differential latency between displays located at endpoints of network, displays being driven by one or more rendering machines and having means for refreshing the images on different displays at the same point in time as well as means adapted so that the content of each displayed image can only change after the completion of previous displayed frame. For example the displays can be frame locked and have double buffered swap locked memory operation. The method or system is adapted to stream test images over the network to the displays of the different endpoints. The test images are displayed on the displays. The displayed images at the different endpoints with an image recording device such as a camera. Optionally the delays can be compensated, e.g. by delaying the streams with lower latency at the level of the frame buffer (FIFO) before or after decoding. Preferably the system or method is adapted to measure end-to-end differential latency between the displays and for putting this in vector form.

Projector methods, devices, software are described for a high decrease of the black level without decrease or a limited decrease of the luminance of the bright pixels for use with high contrast and high dynamic range projectors, e.g. based on RGB lasers or phosphor converted lasers. Such projectors can be used in a digital cinema, in a home theatre, in virtual reality systems, in simulators for training, for example. The projector optical system is adapted to vary, according to an average picture level, an effective étendue of the light source and to keep light power confined within a varying cone angle, whereby at the imaging system the projector étendue is matched to the effective étendue of the light source, the effective light source étendue and the projector étendue being controlled to the average picture level.

An electronic meeting tool and method for communicating arbitrary media content from users at a meeting is described. These can include a node configuration means adapted to operate a display node of a communications network, the display node being coupled to a first display. The node configuration means is adapted to receive user selected arbitrary media content and to control display of the user selected arbitrary media content on the first display. At least one peripheral device adapted to communicate the user selected arbitrary media content via the communications network is provided, wherein the peripheral device is a connection unit comprising: (e) a connector adapted to couple to a port of a processing device having a second display, a memory and an operating system; and (f) a transmitter for communicating with the communications network, A program is provided that is adapted to be loaded onto the processing device and to run on the operating system of the processing device, said program being adapted to obtain user selected arbitrary media content, said program leaving a zero footprint on termination. An input device is provided to allow the user to carry out a user action that triggers transfer of said user selected arbitrary media content to said transmitter through said port.
摘要:
A display has a spatial light modulator 10 for dynamically controlling a luminance of each pixel according to an input signal, the spatial light modulator having a non uniform spatial characteristic, the display also having an optical filter 20 having a spatial pattern to alter the luminance to compensate at least partially for the non uniform spatial characteristic. An electronic signal processing element applies some pre compensation predominantly of higher spatial frequencies for the non uniform spatial characteristic. Such dynamic and optical compensation can enable tuning for different optimizations or for compensating for variations over time. A backlight has an optical source and an optical filter, the source having a colour output which has a non uniform spatial characteristic, and the optical filter having a spatial pattern to alter the colour to compensate in part at least for the non uniform spatial characteristic.
