  • Patent number: 7184593
    Abstract: A method of detecting local features of video which includes the steps of: extracting a first static image and a second static image from a video made up of a plurality of static images; calculating a feature quantity of the first static image and a feature quantity of the second static image; detecting the second static image having a feature quantity such that a difference in feature quantity between the first static image and the second static image satisfies a predetermined condition; and displaying the second static image thus detected and the feature quantity difference in one-to-one correspondence.

  • Patent number: 6654481
    Abstract: A mobile object combination detection apparatus includes a plurality of moving image input units, a plurality of mobile object detection units each connected to one of the moving image input units, and a combination determination unit. Each of the plurality of mobile object detection unit detects a mobile object at a predetermined position on a moving image inputted thereto from the moving image input unit, and sends detection information to the combination determination unit. The combination determination unit compares the detection information of the mobile object sent thereto from each of the mobile object detection unit with a predetermined condition to determine that a target mobile object is detected when the detection information satisfies the predetermined condition.

  • Patent number: 6518978
    Abstract: When an image input button, an image to be edited is acquired and selected pieces of picture data representing the acquired image is displayed. With an order to play back pieces of image data corresponding to the selected pieces of picture data, a play back order is specified by display indicators. When an image output button is pressed, pieces of image data corresponding to the selected pieces of picture data are played back in the specified play back order.
