Patent KR-20010052373-A (KR)
IPC: H04N7/081
Filed: 1999-02-17
Abstract: Methods and devices for detecting a watermark in a watermarked video stream, the watermark having been scaled by an unknown scale among a predetermined finite number of scales and shifted by an unknown number of pixels. For each of the predetermined number of scales, the video stream is divided into a plurality of equally sized scaled watermark blocks; and the plurality of scaled watermark blocks are read into a plurality of read blocks. Each of the read blocks are accumulated into one of a predetermined number of read block bins. The accumulated read blocks are then re-scaled and combined into a single video accumulated block. A predetermined quantity, such as the power of a DCT, is then evaluated within the video accumulated block. This evaluation yields information relative to presence of the watermark in the video stream, the scale applied to the watermarked video and the shift of the watermark, if any, within the watermark blocks. A fractional remainder operation is used to determine the number of read block bins for each scale under consideration as well as to determine the bin into which each read block is to be accumulated.

Abstract: PURPOSE: An exposure controller for a camera mounted on an electric device is provided to properly adjust exposure even when a camera is used to pick up the image of an operator itself. CONSTITUTION: An area integration circuit(28) divides a photographed image into a central area and a peripheral area, and integrates a video signal(22) corresponding to each area. When an operator of a notebook personal computer(2) sets a direction of an image pickup section(12) to photograph the operator itself, a control microcomputer(24) multiplies a greater weight with the former and sums two integration results. The control microcomputer uses the result of sum for exposure information, compares an exposure level represented by the information with a reference level, controls an electronic shutter of an image pickup element(46) and a gain of an amplifier circuit(52) to adjust the exposure of a video camera(10) to have a proper level. Thus, the exposure level is in matching with the reference level. When the image pickup section is directed opposite to the operator, the control microcomputer conducts exposure control.
