A projector in an installation information acquisition method is installed in a real space, has a changeable projection direction, and projects a projection image based on a virtual image. The virtual image is an image in a case where an image arranged at a display position in a virtual space is viewed from a virtual installation position. The method includes first acquisition processing for acquiring positional information of three or more first adjustment points in the virtual space, projection processing for projecting, by the projector, an index image onto the real space, second acquisition processing for acquiring angle information of the projection direction with respect to a reference direction in a state where the index image matches three or more second adjustment points respectively corresponding to the three or more first adjustment points, and third acquisition processing for acquiring installation information based on the positional information and the angle information.

A side camera for a vehicle comprises: a main body disposed at a left-hand and/or a right-hand side of the vehicle; a blind-spot view camera of which at least a portion is accommodated in the main body and being configured to photograph a view in lateral and rearward directions; a surround view camera (SVC) of which at least a portion is accommodated in the main body and being configured to photograph a view in a lateral direction; and a blind-spot view monitor disposed inside the vehicle to transmit an image captured by the blind-spot view camera. When the blind-spot view camera fails, an image transformation process is performed based on an image captured by the SVC and transmitted to the blind-spot view monitor. When the blind-spot view monitor fails, an image captured by the blind-spot view camera is transmitted to another display device in the vehicle.

The present invention discloses a method, an apparatus, and a system for implementing video quality assessment. When video quality is assessed, a proportion of a damaged data caused by packet loss in a video frame in which the damaged data is located is considered, and other factors are also considered, such as a position of the damaged data in the video frame and impact of a scene in which the video frame is located on the video frame or a video frame located after the video frame. Therefore, accuracy of quality assessment is higher.

A signal adjusting device and method, and a test equipment. The signal adjusting device includes: a level controller, a level circuit, a comparison circuit and a selecting circuit. The level circuit is electrically connected with the selecting circuit; the level controller is configured to perform a level adjustment to a first signal, so as to generate a level signal, and the generated level signal is outputted by the level circuit; the comparison circuit is configured to: determine that the level signal meets a preset condition, and generate and output a corresponding feedback signal to the selecting circuit, in response to determining that the level signal satisfies the preset condition; and the selecting circuit is configured to output, as an adjusted signal, the level signal corresponding to the feedback signal.

Examples herein relate to monitor calibration. In some examples, monitor calibration can include a scaler processing resource and a memory resource storing machine readable instructions to cause the scaler processing resource to record, by a sensor included on a monitor, color measurements of the monitor in response to receiving record instructions from an external computing device, transmit the recorded color measurements to the external computing device, receive calibration instructions from the external computing device based on the recorded color measurements, and calibrate the monitor using the calibration instructions received from the external computing device.

The present application discloses a debugging method, a display device driving method, and a display device. The debugging method includes the following steps: generating gamma correction information; and burning, by a testing machine, the gamma correction information into a source driver board of a display device, where the display device further includes a control board, the control board integrates a gamma chip, and the gamma chip obtains the gamma correction information from the source driver board.

A correction image generating system comprises: a main body of an electronic apparatus, which main body comprises a display portion, a storage portion, a correction data generating portion, and an image data correcting portion; and an imaging portion. The predetermined image data is modified reference image data in which a reference image data is corrected by initial correction data generated in a manufacturing phase of the electronic apparatus; the display portion displays the reference image based on the modified reference image data; and the correction data generating portion generates the correction data based on a comparison result between the imaged image data or data based on the imaged image data, and the modified reference image data or data based on the modified reference image data.

A broadcast signal receiving apparatus and a method of controlling thereof are disclosed, and more particularly, to a technology for detecting whether or not an antenna cable is connected to the broadcast signal receiving apparatus. The broadcast signal receiving apparatus includes an antenna connection terminal provide with a detection pin configured to generate a voltage drop by making contact with an antenna cable, and a controller configured to determine whether the antenna cable is connected to the antenna connection terminal by detecting the voltage drop of the detection pin.
