  • Patent number: 8405712
    Abstract: A gesture recognition apparatus including a detector, a controller and a gesture recognizer, and is able to detect a portion to be detected using an image captured at a first resolution without reducing the number of images to be entered per unit of time to an object detector by detecting an auxiliary portion instead when the portion to be detected is not detected at a second resolution, estimating the position of the auxiliary portion based on the position of the auxiliary portion, and extracting the periphery thereof from the image captured at the first resolution.

  • Patent number: 7689000
    Abstract: An image storage device according to an example of the invention comprising a first storage unit which stores first image, a second storage unit which stores second image to be determined whether the second image includes detection target data which is the similar to data included in the first image, parallel comparison units which perform a process of comparing pixel values between a frame of the first image and a frame of the second image, and determining, based on a comparison result between the frame of the first image and the frame of the second image, whether the detection target data is included in the second image in parallel, and a third storage unit which stores, when it is determined that the detection target data is included in the second image, the detection target data.

  • Publication number: 20080159708
    Abstract: A video contents display apparatus include a display generation unit for: generating a predetermined number of static images by considering a time of lapse from information about recorded video contents; converting a static image other than at least one specified static image into an image reduced in a predetermined format from the predetermined number of generated static images; and displaying a sequence of images by arranging the at least one static image and the other static image along a predetermined path on a screen by considering the time of lapse.

  • Publication number: 20080141181
    Abstract: According to one embodiment, there is provided an information processing apparatus. A hand-shape database stores first data representing a first hand shape and second data representing a second hand shape. A hand-shape recognition unit determines whether a received image includes one of the first and second hand shapes. The hand-shape recognition unit outputs first predetermined information when the image includes the first hand shape, and outputs second predetermined information when the image includes the second hand shape. When the first predetermined information is received, a gesture interpretation unit displays on a display a user interface including display items each associated with an executable function, and selects one of the display items in accordance with the position information. When the second predetermined information is received in a state where one of the display items is selected, the gesture interpretation unit executes the function associated with the selected display item.

  • Patent number: 7224842
    Abstract: An object recognition apparatus comprises a moving picture decoding section which decodes data obtained by encoding a moving picture. A background image producing section produces a background image based on encoding information and a reproduction image. An object recognizing section sets a predetermined region to detect a feature quantity of an object, and carries out matching between the reproduction image and the background image, thereby recognizing the object in the moving picture.

  • Patent number: 6111580
    Abstract: An input unit for controlling a device. The input unit first determines whether a user is actively operating the device. If such a detection is made, the input unit then determines whether the user performs an act that corresponds to a command. User attention may be indicated by a user observing the device, approaching the device, facing the device, or speaking. An input command may be indicated by touch, gesture, speech, or line of sight.

  • Patent number: 6049875
    Abstract: A security apparatus. A service is supplied to a user while maintaining the security of the service. A person discrimination section discriminates the user to be supplied the service. A user situation decision section decides whether the user is under a situation to use the service. An infringement situation decision section detects whether a non-user intrudes into a use area of the service in order to decide whether the security of the service is infringed. A service control section supplies the service to the user in case the person discrimination section discriminates the user, and controls a supply of the service if the use situation decision section decides the user is not under the situation to use the service or the infringement situation decision section decides that the security of the service is infringed.
