The present disclosure relates to an image display apparatus. The image display apparatus according to one embodiment of the present disclosure comprises a plurality of input terminals; and a switching circuit including a first receiving end to receive a signal through a first input terminal among the plurality of input terminals, a second receiving end to receive a signal through a second input terminal among the plurality of input terminals, a first transmitting end to transmit a signal received through the first or the second receiving end to a signal processor, and a second transmitting end to output an output signal to the first input terminal in response to a cable being connected between the first and the second input terminal, and a signal being not received. Accordingly, it is possible to determine whether a cable connected to an input terminal is defective.

A residual DC measurement device of the present invention receives light emitted from a display device and outputs a light reception signal, measures a flicker value of the display device on the basis of the light reception signal output while the flicker measurement image is displayed by the display device and stores the flicker value in a storage as an initial flicker value, subsequently causes the display device to display a predetermined display image for a predetermined display time, causes the display device to display the flicker measurement image again when the predetermined display time elapses, measures the flicker value of the display device on the basis of the light reception signal output while the flicker measurement image is displayed and stores the flicker value in the storage as a posterior flicker value, and calculates a flicker change amount by calculating the posterior flicker value stored in the storage and the initial flicker value as an index value representing the residual DC.

Systems, apparatuses, and methods are described for detecting malfunctions of computing devices causing outputs of video content. Partially or fully static content frames may be detected, and, indications may be generated based on the static content frames. The indications may be analyzed to identify computing devices with degraded performance. Diagnostic tests may be run by the identified computing devices and/or other actions performed based on a determination of static content frames.

A measuring method and a measuring system are used for measuring contrast of a display device, including controlling the display device to display a first image, measuring brightness of a central area of the first image, controlling the display device to display a second image, measuring brightness of a central area of the second image, and determining the contrast. Both the first image and the second image have a plurality of areas with different gray scales, the first image includes a maximum gray scale area, and the second image includes a minimum gray scale area.

A positioning assistance device that assists positioning between a content displayed on a display and an object transparently observed through the display is as follows. The positioning assistance device includes: a state calculation unit configured to calculate a supported state of the display relative to the object; an adjustment amount calculation unit configured to calculate, for the supported state, an adjustment amount related to a positioning operation for setting an appropriate positional relation between the content and the object; and a presentation information generation unit configured to generate and output presentation information including the adjustment amount. The adjustment amount calculation unit calculates the adjustment amount by using record data of a positioning operation performed by a user of the display in response to the presentation information output in advance.

A variety of device interfaces may be connected to a test platform in a fast and efficient manner using multi-pin cables and connectors to support high-volume processing of devices to be tested. The multi-pin cables and connectors may aggregate a plurality of specific device interfaces into a single cable that can be connected via a connector to a test shelf and via a connector to a test platform, reducing the time to setup for device testing and facilitating high-volume processing of devices to be tested.

An image analysis system and method determines whether a channel is active by intercepting signals from a set-top box and determining whether the signals correspond to an inactive channel by analyzing pixels, recognized text and/or audio in the signal stream. The system and method controls tuning of the set-top box to each channel to be tested. Data relating to the analysis may be stored and transmitted for processing credit requests.
