摘要:
Color calibration of color image rendering devices, such as large color displays, which operate by either projection or emission of images, utilize internal color measurement instrument or external color measurement modules locatable on a wall or speaker. A dual use camera is provided for a portable or laptop computer, or a cellular phone, handset, personal digital assistant or other handheld device with a digital camera, in which one of the camera or a display is movable with respect to the other to enable the camera in a first mode to capture images of the display for enabling calibration of the display, and in a second mode for capturing image other than of the display. The displays may represent rendering devices for enabling virtual proofing in a network, or may be part of stand-alone systems and apparatuses for color calibration. Improved calibration is also provided for sensing and correcting for non-uniformities of rendering devices, such as color displays, printer, presses, or other color image rendering device.

A projection system capable of projection alignment includes a projector, a shaped projection screen, an image sensor, and a processing unit. The projector is configured to project a series of alignment content to the shaped projection screen. The image sensor is configured to capture a series of projected alignment content. The processing unit is electronically coupled to the image sensor and configured to receive the series of captured alignment content and determine at least part of general boundary of the shaped projection screen based on the series of captured alignment content.

A set-top box with self-monitoring and system and method for use of the same are disclosed. In one embodiment of the set-top box, a housing secures a television input, a television output, a processor, memory, and storage therein, which are communicatively interconnected by a busing architecture. The memory is accessible to the processor, and the memory includes processor-executable instructions that, when executed, cause the processor to detect when the television is not being utilized. Responsive thereto, the instructions cause the processor to scan channels received from the television input and generate a composite TV screen image data that may be resolved to a single TV screen image made from an assemblage of TV screen image captures corresponding to the scanned channels.

Embodiments of the disclosure provide a display apparatus, a display apparatus fault analysis system and a display apparatus fault analysis method. The display apparatus fault analysis system comprises a display apparatus and a server. The display apparatus comprises: a display chip configured to generate a target video or a target image according to a display instruction; an image capturer configured to capture the target image; a detection unit configured to, upon receipt of a fault detection instruction, send the display instruction to the display chip, compare the target image frame or the target image with a predetermined reference image to obtain a difference between the target image frame or the target image and the predetermined reference image, and generate a fault code based on the difference; and a communication module configured to transmit the fault code to a server.

The present invention relates to an automatic test system for a digital display system, which digital display system comprises display electronics configured to output a digital video stream, and a display screen connected to the display electronics to receive the digital video stream generated thereby and to display at least one image based on the received digital video stream. The automatic test system is designed to be connected to the digital display system to receive the digital video stream generated by the display electronics, and is configured to: reconstruct in memory an image based on the received digital video stream; compute a signature of the reconstructed-in-memory image; and test the digital display system by comparing the computed signature with a reference signature so as to thereby check whether the reconstructed-in-memory image completely matches an expected good display behavior, wherein said reference signature is indicative of said expected good display behavior.

A set-top box (STB) determines an occurrence of a first STB error during operation of the STB, and identifies a first error code that corresponds to the first STB error. The STB maps the first error code to a first self-help video of multiple self-help videos stored at the STB, and plays back the first self-video via a display device coupled to the STB.

One aspect of the disclosure directs to a signage device, which include a display device, a camera, and a signage controller. The display device is configured to display media content in a display mode and display diagnostic information in a diagnostic mode. The diagnostic information includes content operational and deployment information related to the media content being displayed, and system information of the signage device. The signage controller is configured to control the camera to capture an image frame, process the captured image frame to generate information for a server system such that the server system provides the media content to the signage controller based on the generated information, display the media content on the display device in the display mode, switch the display device to the diagnostic mode in response to a diagnostic input command, and display the diagnostic information on the display device in the diagnostic mode.

Method and system for testing any type of video display, video monitor or other device that produces a video signal, and that is capable of providing information about the video and optionally audio specifications and/or capabilities of the output signal to an external device when coupled thereto. The external device obtains the information about the specifications and/or capabilities and based thereon, assembles one or more pre-defined tests from a test database/repository containing tests to enable testing of compliance of the video signal producing device to those specifications and/or capabilities. This compliance testing may entail generating video or audio content at a source generator, providing it to the video signal producing device, and determining the accuracy of the output of the video signal producing device to the input content. A determination of the results of this test may be provided to an operator of the testing apparatus.
摘要:
An on-screen menu method and system for controlling the functions of integrated electronic devices and a television schedule system and method for displaying television schedule information on a television screen includes a program guide having a schedule information area that depicts the programs that are being presented on each channel at each time during the day and an interconnected series of menus to control the features of the integrated electronic devices. An input device allows the viewer to move a pointer over different interactive areas of the guide and the function performed when the area is activated is displayed in a contextual help window. Various control glyphs provide for recursive interaction with the guide.
