Title: Video tape recorder
Inventor: KAJINO EIICHI
IPC: G11B27/00
Filed: 1999-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a video tape recorder that can provide information useful to retrieve a video image recorded on a video recording tape to the video recording tape itself. SOLUTION: For example, heads SP-, SP+ record a video image photographed by a camera 14 onto the video recording tape 7 via a video recording processing circuit 12 and a switch preamplifier circuit 11. A controller 16 writes data and time information at a point when receiving an alarm signal to a memory 17. When the tape end comes, the video recording tape 17 is rewound and reaches a state that the tape top is wound on a rotary head cylinder 6. An OSD 18 generates a black/white character video image on the basis of the date and time information read from the memory 17 and records the video image onto the tape top. Thus, upon reproducing the video image on the tape top as a still picture, when the video image is recorded can be recognized.  Furthermore, since color killer is active when the still picture at the tape top is reproduced, uneasy to see image due to colored display characters can be eliminated.

Title: Image recognition based measuring method and recording medium
Inventor: YOMO HIROMI
IPC: H05K1/02
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To reduce the load of pattern matching processing and to shorten processing time by performing pattern matching of an object only while excluding its background. SOLUTION: A reference image for pattern matching equal with or similar to the object of a measuring object input image and the mean value of density distribution of its background is registered. A source image of the object is displayed, and the object and its background are separated. A search frame is set while excluding its background part from the pattern image, and scanning is performed with the pattern image in order to detect the object inside the search frame. In this process, a mutually correlative coefficient is calculated between the object part of the pattern image and a positionally corresponding input image. Besides, a self-correlative coefficient of the input image corresponding to the object area of the pattern image is calculated. Then, a normalization correlative coefficient is found between the object part of the pattern image and the corresponding input image.  The largest value of the normalization correlative coefficient and the position of the pattern image are selected. The position of the pattern image becomes a pattern detecting position.
