摘要： To provide a processing method for reducing motion blur while increasing resolution. By performing a super-resolution process, a resolution-increased image is obtained from an input image in multiple frames. By performing an enlargement process, an enlarged image is obtained from the input image in one frame. A high-frequency image is obtained by subtracting the enlarged image from the resolution-increased image. A high spatial frequency-emphasized image is obtained by adding the high-frequency image to the resolution-increased image. The enlarged image and high spatial frequency-emphasized image are displayed alternately every half frame.

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： A moving object is detected from a movie. The actual movie has a complicated background. In order to detect the moving object, the invention is constructed to comprise, in addition to means 500 for inputting the movie, and display 300 for outputting the processed result: means 700 for judging the interval which is predicted to belong to the background as to a pixel region in the movie; means 800 for extracting the moving object; and means 900 for calculating the moving direction and velocity of the moving object.Thanks to the above-specified construction, even under the complicated background in which not only the change in the illumination condition but also the structure change will occur, the presence of the structure change of the background can be judged to detect/extract the moving object on real time. Moreover, the moving direction and velocity of the moving object can also be calculated.

摘要： The present invention is intended to provide an image recognition method which, in recognizing an input image including an object presumable to have continuity like a human figure, enables simultaneously detecting the shape of the object in the input image and cutting-out the object therefrom, and obtaining information on position of the object at the same time, and which also enables recognition of two objects having the same shape but having different sizes. The processing procedure of image recognition according to the present invention consists of: inputting an input frame image of an object by image data inputting means; preparing scaled-down images 1 to n at different resolutions by image size reducing means; calculating neighborhood correlation values for respective scaled-down images 1 to n by neighborhood correlation processing means and checking relationship between them at the same time; calculating the area and the gravity center of each image using pixel values and pixel coordinate value; identifying respective objects at respective resolution on the basis of their relationship; determining shape correlation of each object; and recognizing the shape of each object by comparing the obtained shape auto-correlation with a previously determined reference value.
