  • Publication number: 20240121373
    Abstract: Disclosed are an image display method and a 3d display system. The method is adapted to the 3d display system including a 3d display device and includes the following steps. A first image and a second image are obtained by splitting an input image according to a 3d image format. Whether the input image is a 3D format image complying with the 3D image format is determined through a stereo matching processing performed on the first image and the second image. An image interweaving process is enabled to be performed on the input image to generate an interweaving image in response to determining that the input image is the 3D format image complying with the 3D image format, and the interweaving image is displayed via the 3D display device.

  • Publication number: 20230211473
    Abstract: A carrying device is provided. The carrying device includes a stand, an upper clamp connected to the stand, a lower clamp assembled to the stand, a manipulation mechanism assembled to the stand and interlinked with the lower clamp, and a supporting column assembled to the lower clamp. The manipulation mechanism can drive the lower clamp to move relative to the upper clamp, and the upper clamp and the lower clamp jointly define a receiving space therebetween. The supporting column is movable relative to the lower clamp, so that the carrying device can be adjusted in a first clamping mode or a second clamping mode. When the carrying device is in the first clamping mode, the supporting column is located in the receiving space and faces toward the upper clamp, so that the supporting column and the upper clamp can jointly clamp a plate part of a first structure.

  • Publication number: 20230199422
    Abstract: An audio system is proposed, dynamically playing optimized audio signals based on user position. A sensor circuits dynamically senses a target space to generate field context information. First speaker and second speaker are arranged for audio playback. A host device recognizes a user from the field context information, determines the user position corresponding to the target space, and adaptively assigns the user position as a target listening spot. A sensor circuit contains a camera capturing an ambient image out of the target space. A recognizer circuit analyzes the ambient image to obtain from the target space, the location, size and acoustic attribute information of an ambient object, allowing the control circuit to accordingly perform an object-based compensation operation on the target listening spot to generate optimized first channel audio signal and second channel audio signal.
