Publication number: 20240119910Abstract: The invention provides an image capture device and an image processing method thereof. The image processing method includes the following steps. First, an image signal source is received by a receiving unit, wherein the image signal source has a plurality of image frames and plurality corresponding image information or plurality of corresponding variable refresh rate (VRR) related information. Next, it is determined whether the image signal source is a VRR signal, and a determination result is generated. A time stamp of each image frame is calculated according to the VRR-related information if the determination result is positive, wherein the time stamps correspond to a dynamic frame interval respectively. Next, the image frames are respectively converted into a corresponding output packet. Finally, the output packets are respectively integrated with their respective time stamps to generate a dynamic frame interval output packet.Type: ApplicationFiled: October 3, 2023Publication date: April 11, 2024Inventors: Yen-Cheng Yao, Chia-Jung Hsiao

Patent number: 11095828Abstract: A video signal conversion device includes a front end interface, a rear end interface, a video detector and a video processor. The front end interface is coupled to a video source to receive an input signal. The rear end interface is coupled to a video receiver. The video detector determines whether the input signal corresponds to HDR imaging format. The video detector generates a conversion command in response to the input signal corresponding to HDR imaging format. The video processor is coupled to the front end interface, the rear end interface and the video detector. When the video processor receives the conversion command, the video processor converts the input signal into an output signal with SDR imaging format. The video processor sends the output signal to the video receiver via the rear end interface.Type: GrantFiled: April 2, 2019Date of Patent: August 17, 2021Assignee: AVerMedia TECHNOLOGIES, INC.Inventors: Wen-Chien Chang, Yen-Cheng Yao
