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.

摘要： Only a video cut (containing a frame) designated by a user is automatically and correctly extracted directly from a video image under playing operation at high speed. A judgement is made as to whether or not the frame of the video image is designated by the user. When such a user designation is made, a detection is made of a change point in the video cut containing this designated frame (reverse playing direction, forward playing direction). Under such a condition that a frame image immediately before this change point is displayed, the playing operation of the video image is brought into a pause state. Accordingly, only the video cut desired by the user can be extracted during a single playing operation of the video image, and the video image can be edited in a high efficiency.

摘要： For image recording/reproduction in a monitoring system, a monitoring image signal as inputted is converted into a plurality of time-serial digitized monitoring image frames to be stored temporarily in a first storage area. From the plurality of digitized monitoring image frames stored in the first storage area, a plurality of monitoring image frames relevant to at least one type of concerned event for monitoring are extracted to be stored in a second storage area. A monitored event database having a data structure comprised of elements each containing information concerning a storing location of relevant monitoring image frame in the second storage area and information concerning attributes of the relevant monitoring image frame for each of the monitoring image frames stored in the second storage area is generated to be stored in a third storage area. In response to a perusal request issued by user by using a WEB browser and sent via a network, the monitored event database is searched for acquiring a storing location of plural monitoring image frames relevant to the perusal request in the second storage area to thereby select from the second storage area a plurality of monitoring image frames relevant to the perusal request. The selected plural monitoring image frames are converted into HTML data to be sent to a display device connected via a network to be displayed on a display device in a two-dimensional layout or in the form of time-serial animation.

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： 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.
