摘要： A lifting device is provided. The lifting device includes a stationary member, a lifting member, positioning bases, reels, and springs. The lifting member is slidably coupled to the stationary member. The lifting member is fixed to a back portion of the display. The positioning bases are disposed on the stationary member and the lifting member. The reels are pivoted on the positioning bases. The springs are wound around the reels and connected to the other of the stationary member and the lifting member relative to the positioning bases. When the display or the lifting member is subjected to an applied force toward a sliding direction, the lifting member slides toward the sliding direction relative to the stationary member. The springs stretched by the lifting member generate an elastic force, so that the lifting member and the display no longer subjected to a force stay at a height position after sliding.

摘要： The present disclosure provides a video image composition method including the following steps. A priority level list is obtained, and the priority level list includes multiple priority levels of multiple person identities. Multiple video streams are received. Multiple identity labels corresponding to human face frame images from the video streams are determined. The multiple display levels of the human face frame images are determined according to the identity labels and priority level list. A part of the human face frame images being in speaking status are detected. At least one of the part of the human face frame images being in speaking status is constituted as a main display area of a video image, according to the display levels.

摘要： A camera lifting structure includes a rail bracket, two fixing portions, two elastic elements, two sliding portions, two connecting rods and a camera module. The rail bracket extends along a first direction. The fixing portions are disposed on two ends of the rail bracket. The elastic elements locate between the fixing portions. Each elastic element has a first end and a second end. Each first end connects with the corresponding fixing portion. The sliding portions respectively connect with the corresponding second end and are configured to slide along the first direction relative to the rail bracket. Each connecting rod has a third end and a fourth end. Each third end is pivotally connected with the corresponding sliding portion. The camera module pivotally connects with the fourth ends and is configured to move relative to the rail bracket along a second direction perpendicular to the first direction.

摘要： The present disclosure relates to a display device including a display circuit, a sensor, a light control circuit and a processing circuit. The display unit includes a first display unit and a second display unit adjacent to the first display unit. The sensor obtains a first brightness value of the first display unit and a second brightness value of the second display unit. The light control circuit adjusts the light transmittance of multiple light control units of the light control circuit. The processing circuit calculates a brightness difference ratio value according to the first brightness value and the second brightness value. When the brightness difference ratio value is greater than a threshold value, the processing circuit adjusts a light control signal to change the light transmittance corresponding to the position of the second display unit.

摘要： A resonant testing system for testing a device under test, including a processing circuit, a microphone array and a camera is disclosed. The processing circuit generates a scanning frequency signal and transmits the scanning frequency signal to the device under test, which plays sound based on the scanning frequency signal. The microphone array includes several microphones, each of the microphones receives the sound played by the device under test, and the microphone array outputs several audio signals corresponding to the microphones. The camera captures a real time image signal of the device under test, and transmits the real time image signal to the processing circuit. The processing circuit computes resonant positions and resonant levels according to the audio signals, and combines the resonant positions, the resonant levels and the real time image signal to generate a real time resonant result. A resonance testing method is disclosed.
