Title: Device and method for decoding image
Inventor: OGURA YOSHIYUKI
IPC: H04N19/91
Filed: 2002-05-27
Abstract: <P>PROBLEM TO BE SOLVED: To reduce deterioration in image quality by suppressing error propagation involved in error concealing processing even when an image block during decoding refers to a frame including an error in motion compensation.   <P>SOLUTION: An MPEG decoding device 10 is provided with a motion compensation circuit 15 and an error map table 19 holding an error map table for decoded frames to be referred to in performing the motion compensation. The error map table 19 shows error blocks that are present in the decoded frames. The motion compensation circuit 15 refers to the error map table 19, and performs error concealing processing that compensates pixels in a decoding object block with pixels of the decoded frame and outputs the block when an error block is included in blocks included in a reference area or when moving image encoded data in the decoding object block are damaged. The motion compensation circuit 15 also generates and stores an error map table, wherein a block subjected to the error concealing processing is defined as an error block.  <P>COPYRIGHT: (C)2004,JPO

IPC: G01F23/28
Filed: 2002-05-27
Abstract: <P>PROBLEM TO BE SOLVED: To provide a river observing apparatus capable of detecting the quantity of flow of a river.   <P>SOLUTION: A television camera 11 picks up images including images across the approximately whole width of the river in the vicinity of a location at which a higher step on the upstream side and a lower step on the downstream side are formed across the width of the river. The picked-up images are converted into digital data by an A/D converter 12 and stored in an image memory 13. Regions having high luminance in the images correspond to regions in which the water is turbid. A processing part 14 binarizes the images in the image memory 13 to acquire binarized image data. Based on the binarized image data, the processing part 14 determines both the overall width of the actual area of water flow of the river in the widthwise direction of the river in the vicinity of the steps, and a water level on the higher side in the vicinity of the steps in the actual area of water flow of the river. The processing part determines the quantity of flow of the river based on the determined overall width and the water level.  <P>COPYRIGHT: (C)2004,JPO
