Publication number: 20140198219Abstract: A multi-function control illumination device has a synchronization separator, a parameter setting device, a light emitting device, and a video processor. The synchronization separator connects with a video camera and the parameter setting device connecting with the light emitting device. The synchronization separator receives a video signal from the video camera, retrieves a synchronization signal from the video signal, and outputs the synchronization signal to the parameter setting device. The parameter setting device generates an electric signal corresponding to the synchronization signal according to at least one illumination parameter and outputs the electric signal to the light emitting device. The light emitting device emits toward a shooting direction of the video camera a light beam whose intensity periodically varies according to the electric signal.Type: ApplicationFiled: May 9, 2013Publication date: July 17, 2014Applicant: NATIONAL CHIAO TUNG UNIVERSITYInventors: JEN-HUI CHUANG, WEN-CHIH TENG

Patent number: 8218011Abstract: If an active smart node detects that an object leaves a center region of a FOV for a boundary region, the active smart node predicts a possible path of the object. When the object gets out of the FOV, the active smart node predicts the object appears in a FOV of another smart node according to the possible path and a spatial relation between cameras. The active smart node notifies another smart node to become a semi-active smart node which determines an image characteristic similarity between the object and a new object and returns to the active smart node if a condition is satisfied. The active smart node compares the returned characteristic similarity, an object discovery time at the semi-active smart node, and a distance between the active smart node and the semi-active smart node to calculate possibility.Type: GrantFiled: August 20, 2009Date of Patent: July 10, 2012Assignee: Industrial Technology Research InstituteInventors: Sung-Ping Cheng, Lih-Guong Jang, Jen-Yau Kuo, Jen-Hui Chuang

Patent number: 8139898Abstract: An image processing device includes an image acquisition module, a memory module, and an image signal processing module, for performing an image enlargement and enhancement. The image acquisition module sequentially reads in an image block, including a unit pixel matrix and an exterior pixel matrix, wherein each pixel matrix includes a plurality of pixels and each pixel is associated with a parameter. The memory module stores a plurality of predefined edge patterns. The image signal processing module compares a loaded image block with predefined edge patterns, and determines if it is an edge block. Then, the image signal processing module further classifies its pixels into two groups, and calculates a continuous separating boundary between the two groups. Finally, the image signal processing module enlarges an edge block by placing new pixels inside its unit pixel matrix, wherein the new pixel parameters are extrapolated from the two classified pixel groups to maintain a sharp edge boundary.Type: GrantFiled: April 30, 2008Date of Patent: March 20, 2012Assignee: AU Optronics CorporationInventors: Jen-Hui Chuang, Szu-Hui Wu, Horng-Horng Lin, Shih-Shiung Huang, Yao-Jen Hsieh
