  • Patent number: 11355040
    Abstract: A method for inspecting functionality of a display device and a test equipment are provided. The method for inspecting functionality of the display device is utilized in a test equipment of an auto-test system. The method includes controlling an image capturing device to capture a test image shown on a screen of the display device for generating a captured image, acquiring an encoded pattern from the captured image and decoding the encoded pattern, wherein the test image is a source image generated by an image providing device superposed with the encoded pattern, determining whether the encoded pattern is successfully decoded to generate a resultant data, and comparing the resultant data with reference data to generate a comparison result after the encoded pattern is successfully decoded, wherein the reference data comprises information associated with the test image and information associated with system configuration of the display device.

  • Patent number: 10965841
    Abstract: A receiving device for reducing video latency includes a display render unit, a communication interface, a memory, and a processor. The display render unit performs a video transmission to output a video to a display apparatus. The video generated by a video capture unit of the sending device is transmitted through the communication interface to the receiving device. The memory stores at least one computer readable instruction. The processor accesses and executes the at least one computer readable instruction to: determine whether a video latency is necessary to be reduced; determine a target reduced latency based on a target line count and a current line count; and determine a first period based on the target reduced latency and an accelerating scheme at the display render unit. The display render unit performs the video transmission to the display apparatus based on the accelerating scheme for the first period.

  • Publication number: 20090113484
    Abstract: An image output device and image processing method are provided. The device includes a front end control unit and a color blending processing unit. The front end control unit switches a first program channel to a second program channel according to a channel switching signal and stores a final frame data of the first program channel and an initial frame data of the second program channel. The color blending processing unit receives a blending information and blends the final frame data of the first program channel and the initial frame data of the second program channel according to the blending information. Thus, the transition frame produced by the color blending processing unit is displayed between the final frame of the first program channel and the initial frame of the second program channel.
