摘要： A system for detecting a point of change between video shots from a video having a plurality of succeeding frames. The system includes video playback apparatus for playing a video chronologically one frame at a time, and a display for displaying the video. The a processing device for calculating a feature quantity of video image data for each frame, determining a first correlation coefficient between a feature quantity of a current frame and a feature quantity calculated from an immediately preceding frame and determining a second correlation coefficient between the feature quantity of the current frame and a feature quantity of at least two frames preceding the current frame, and indicating on the display a point of change between video shots when the first correlation coefficient and the second correlation coefficient are out of predetermined allowable ranges. The correlation coefficients of each frame is stored and can be used by the processing device to dynamically change a reference used for detecting a point of change between video shots. The change in the reference is performed based on the stored correlation coefficients or feature quantities of past frames.

摘要： There is provided a video retrieval method, and apparatus, capable of fast matching a feature of a target video with a feature of an enquiry video without conducting work of providing keywords for video retrieval. As for the target video, both a video which is being broadcasted and a video included in a data base can be dealt with. A retrieval method includes the steps of providing a representative frame image specified by a user with a code or a code string as a name thereof, and registering beforehand code strings of a plurality of representative frame images as enquiry video names; inputting a target video; extracting a representative frame image from the video; calculating one feature or a plurality of features from a whole or a part of the frame image; assigning a corresponding code to the feature or each of the features; providing the frame image with the code or a code string arranged in a predetermined order as a name thereof, and producing a video name for the video in a form of a frame name string corresponding to a string of the frames; and matching the enquiry video names with the video name by using the frame name string and outputting a result.

摘要： In order to reduce the load on the operator in monitoring a moving object in the moving picture signal supplied from the imaging device, the signal is displayed in one region of the display device. The moving route of the moving object which has entered the view of the imaging device is extracted, based on the signal. The first image data showing the image of a moving route of an extracted moving object is generated, and the second image data showing the image of the moving object is generated based on the signal. The overlapped image of the image of the moving route and the image of the moving object is displayed in another region of the display device together with the extraction time of the image of the moving object. The processing above is repeated to other moving objects which enter the view later on. The overlapped images for different moving images thus extracted are displayed adjacent to each other in the region.

摘要： An economical surveillance apparatus robust to an environmental change includes an input unit for inputting images in a time series, a background image memory unit for storing a plurality of input images, a difference image memory unit for calculating and storing difference degree between a plurality of background images of the background image memory unit and an image inputted afresh, and a judging unit for judging an existence/absence of an invading object by utilizing the value of the difference degree of the difference image memory unit. This surveillance apparatus can automatically register a plurality of background images from a camera image. Since the background images that are no longer used are automatically erased, the drop of detection speed and detection sensitivity can be prevented.

摘要： A method of characterizing a video includes the steps of extracting frame images from an input video, calculating a time length between each of the frame images and a next one of the frame images, assigning index information determined by the calculated time length to each of the frame images, stringing together the index information assigned to the frame images, and characterizing the input video by the strung-together index information. The index information is a character code, and the strung-together index information is a character code string. The frame images include head frame images located at scene changes of the input video. The input video is being broadcasted or is included in a data base.

摘要： A method and apparatus for displaying a representative image corresponding to a shot of a duration within a specified range included in a plurality of shots of a moving image. The moving image includes a plurality of successive frames each having an image and each shot includes a plurality of the successive frames. In the invention a plurality of shot change points are sequentially detected from the moving image. The shot change points represent points between a pair of frames where images of a preceding shot and images of a succeeding shot have changed. Thereafter a detection is performed to determine whether a duration of a shot between a preceding shot change point and a succeeding shot change point is within the specified range. A representative image corresponding to the shot having a duration within the specified range is displayed along with duration time information representing the duration of the shot. A reduced image from the shot can be displayed as the representative image and the number of detected shots having a duration within the specified range can be reduced according to preset conditions.
