Patent number: 6965402Abstract: Digital pictures are taken by a digital camera. The digital camera provides picture data with a large dynamic range of, for example, 10 bit. Data processing and display devices operate with 8 bit only, i.e. do not take advantage of the high dynamic range of the camera. This is important in traffic monitoring installations, where, on one hand, the driver in a relatively dark passenger compartment of a vehicle and, on the other hand, the bright license plate have to be recognized to provide evidence in court. For this reason, a dark picture and a bright picture are derived from the picture data provided by the camera. This is done by reading, on one hand, the eight least significant digits and, on the other hand, the eight most significant digits of the camera output to provide the dark and bright pictures, respectively. The dark and bright pictures thus obtained are balanced against color, gray, contrast or brightness values of histograms derived from previous pictures.Type: GrantFiled: December 15, 2000Date of Patent: November 15, 2005Assignee: Robot Foto und Electronic GmbHInventors: Thomas Schmitz, Wolfgang Guse

Publication number: 20020135703Abstract: Digital pictures are taken by a digital camera. The digital camera provides picture data with a large dynamic range of, for example, 10 bit. Data processing and display devices operate with 8 bit only, i.e do not take advantage of the high dynamic range of the camera This is important in traffic monitoring installations, where, on one hand, the driver in a relatively dark passenger compartment of a vehicle and, on the other hand, the bright license plate have to be recognized to provide evidence in court. For this reason, a dark picture and a bright picture are derived from the picture data provided by the camera. This is done by reading, on one hand, the eight least significant digits and, on the other hand, the eight most significant digits of the camera output to provide the dark and bright pictures, respectively. The dark and bright pictures thus obtained are balanced against color, gray, contrast or brightness values of histograms derived from previous pictures.Type: ApplicationFiled: December 15, 2000Publication date: September 26, 2002Applicant: Robot Foto und electronic GmbhInventors: Thomas Schmitz, Wolfgang Guse

Publication number: 20020067432Abstract: A video decoder is connected with a block distortion detector for specifying the boundary of blocks where block boundary occurs, using decoded image data and information of motion vectors, which are supplied from the video decoder; and a block distortion remover for subjecting pixels in the vicinity of the block boundary of the decoded image to filtering on the basis of the result of detection from the block distortion detector, thereby removing the block distortion. Therefore, block distortion is accurately detected when a compressed and coded image is decoded, and the detected block distortion is removed while minimizing the blurriness of the image.Type: ApplicationFiled: October 22, 2001Publication date: June 6, 2002Inventors: Satoshi Kondo, Tetsuya Itani

Patent number: 6285361Abstract: Disclosed is a method for clipping a segment from a video file having a multiplicity of video frames. Preferably, at least some of the frames in the video file are encoded as predicted frames. The method includes selecting a mark-in location in the video file that defines the beginning of the clipped segment. A mark-out location defining the end of the clipped segment is also selected in the video file. Once the mark-in and mark-out locations are selected, the method decodes a first frame associated with one of the mark-in location and the mark-out location. The first frame is preferably a predictive frame that has an associated first format. The first frame is then re-encoded into a second format and stored. The method then proceeds to create a clipped segment that includes the re-encoded first frame.Type: GrantFiled: October 9, 1997Date of Patent: September 4, 2001Assignee: FutureTel, Inc.Inventors: Eric T. Brewer, Andrew Palfreyman, Thomas S. Gilley

Patent number: RE41966Abstract: A monitor control system capable of reprogramming the function of a LCD monitor. The monitor control system utilizes VGA signal lines for video signal transmission during normal mode of operation and the same VGA signal lines for transmitting erase/record commands and data when the erasable programmable ROM inside the monitor demands reprogramming. Using an isolator circuit in the monitor control system for isolating an erase/record pathway of an erasable programmable ROM from a normal video pathway, data within the erasable programmable ROM can be modified without opening up the monitor casing. Hence, the modification of monitor function is much more convenient.Type: GrantFiled: October 1, 2008Date of Patent: November 30, 2010Assignee: Novatek Microelectronics Corp.Inventor: Te-Hsiu Tsai
