Publication number: 20240144575Abstract: A 3D image sensing device includes a first camera lens, a second camera lens and a light source. A 3D image processing method for the 3D image sensing device includes the following steps. Firstly, a target is photographed by the first camera lens and the second camera lens, and the obtained images are processed in a stereo vision mode. Consequently, a first depth map is obtained. After the light source emits plural feature points to the target, the target is photographed by the first camera lens and the second camera lens, and the obtained images are processed in an active stereo vision mode. Consequently, a second depth map is obtained. The first depth map and the second depth map are synthesized as a synthesized depth map according to a synthetization strategy.Type: ApplicationFiled: January 17, 2023Publication date: May 2, 2024Inventors: HSIU-WEN WANG, CHIH-WEN LIN

Publication number: 20220377315Abstract: A method for aligning a camera lens with a light source is provided. The method is used in an aligning system. The aligning system includes an alignment element, a reference camera and a fixture. Firstly, the reference camera shoots a reference chart on the alignment element. Then, the light source is placed on the fixture. The light source illuminates the alignment element to generate an illumination result. The reference camera shoots the illumination result. If the illumination result does not comply with a preset specification represented by the reference chart, the fixture adjusts the light source. Then, the camera lens is placed on the fixture. Then, the camera lens shoots the reference chart on the alignment element to acquire a shooting result. If the shooting result does not comply with the preset specification, the fixture adjusts the camera lens.Type: ApplicationFiled: July 23, 2021Publication date: November 24, 2022Inventors: HSIU-WEN WANG, CHIH-WEN LIN

Patent number: 8421778Abstract: A device and method is provided to selectively modify the transmission performance of a frame data. Through a parallel transmission interface, the frame data is transmitted under a corresponding interface protocol and transmitted toward an image display. The method first detects a data size of the frame data and then provides a transmission control signal based on the detection of the data size. Next, selectively divide the frame data by a factor M based on the transmission control signal. Furthermore, transmit the divided frame data at a raised clock rate based on the factor M. Afterwards, temporarily store the divided frame data about to be transmitted toward the image display until the whole frame data is transmitted.Type: GrantFiled: April 24, 2008Date of Patent: April 16, 2013Assignee: Alpha Imaging Technology Corp.Inventors: Hsiu-Wen Wang, Wei-Hao Yuan, Wei-Cheng Chang Chien, Ming-Jun Hsiao
