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.

A method for testing crosstalk of a screen. The method includes when a main screen and a secondary screen simultaneously display pictures of different grayscales, determining a standard parameter value of crosstalk for each of the secondary screen and the main screen caused by the other; determining an actual parameter value of crosstalk for each of the secondary screen and the main screen caused by the other; calculating a degree of crosstalk for each of the secondary screen and the main screen caused by the other, according to the standard parameter value of crosstalk and actual parameter value of crosstalk for each of the secondary screen and the main screen caused by the other, respectively.

A display device failure detection method, device and system are disclosed. The display device failure detection method includes that: at least one detection picture image acquired by an image acquisition device when a target display device regularly displays a detection picture sequence is received, and at least one image to be detected is determined from the at least one detection picture image (S11); at least one region to be detected corresponding to at least one display region of the target display device in the at least one image to be detected is determined, and image data of the at least one region to be detected is processed to obtain at least one image processing result (S13); and whether a display exception occurs to the target display device is judged according to the image processing result (S15).

An intelligent television can provide various interfaces for providing video-on-demand (VOD). The user interfaces include unique visual representations and organizations that allow the user to utilize the intelligent television more easily and more effectively. Particularly, the user interfaces pertain to the display of VOD content and better organizations thereof. Further, the user interfaces provide unique process of transitioning between the VOD content.

What is disclosed are systems and methods of optical correction for pixel evaluation and correction for active matrix light emitting diode device (AMOLED) and other emissive displays. Optical correction for correcting for non-homogeneity of a display panel uses sparse display test patterns in conjunction with a defocused camera as the measurement device to avoid aliasing (moiré) of the pixels of the display in the captured images.

Optical correction for correcting for non-homogeneity of a display panel uses sparse display test patterns in conjunction with a defocused camera as the measurement device to avoid aliasing (moiré) of the pixels of the display in the captured images.

The invention relates to a method for reducing aliasing errors in a moire-corrected final image formed by at least one camera image, wherein the at least one camera image is captured, by a camera (1) having imaging optics (1.1) and a sensor surface (1.2) with sensor pixels (1.3), as the depiction of a display image of a display device (2) with display pixels (2.1) arranged in a matrix-like manner and spaced apart in a display pixel pitch (D A) on the sensor surface (1.2), wherein, during the capture, the camera (1) is shifted relative to the display device (2) along at least one offset path (VP) in relation to a starting position (S). The invention also relates to a method for evaluating the presentation quality of a pixel-based display device (2), and a device for carrying out methods of this type.

A method and apparatus for measuring a dynamic crosstalk are provided. The method may include: controlling a driver configured to cause a camera to have a dynamic movement; at either one or both of a left eye position and a right eye position of a user, capturing a stereo pattern image output through a three-dimensional (3D) display, by the camera while the camera is in the dynamic movement; and measuring the dynamic crosstalk occurring by the 3D display based on the stereo pattern image captured by the camera.
