  • Patent number: 8265381
    Abstract: To provide a sign authentication system and method for authenticating the originality of an object having a sign such as a seal or a signature or a pattern which can be deemed as a sign, making counterfeit very difficult even if the mechanism of authentication is revealed, obviating the need for being additionally provided with a special device such as an IC chip used for authenticating the originality. A sign authentication system provides reading a sign such as a personal seal impression as color information for each mesh division, extracting feature points from the color information and storing them, and creating a code for authentication from the feature points. The sign is made with an ink containing color material particles smaller than the mesh division. The feature points on the basis of variation of color information caused are extracted when the mesh division is shifted.

  • Patent number: 8265420
    Abstract: Techniques are disclosed for correcting the exposure of a digital image. An exposure predictor may be generated based on a set of images for which ground truth data are known. After identifying an optimal set of features, the exposure of the digital image may be corrected by extracting values of the selected optimal features from the image, using the predictor to predict a desired exposure correction for the image, and correcting the exposure of the image by the predicted desired amount. Exposure correction is based on a model that relates intensity of light in the world to the RGB digits of the digital image. The model comprises a gamma function that models the response of a typical monitor and a S-shaped curve that compresses the large dynamic range of the world to the small dynamic range of the RGB digit space.

  • Patent number: 8254683
    Abstract: When a small block area enters a first two-dimensional code during a scan and features of the image within the area of a position in the first two-dimensional code coincide with a two-dimensional code, the block area is specified as containing a code and a recognition process is performed in the nearby areas. When the recognition of the two-dimensional code has been successful, the area of the first two-dimensional code is further extracted. When the extraction of the area of the first two-dimensional code has been successful, the scan using the small block area is further continued to search for a second two-dimensional code. With an already recognized entrance to the area of the first two-dimensional code, the area is skipped to continue the search. The second two-dimensional code is detected at a high speed by repeating the operation.

  • Patent number: 8244051
    Abstract: Embodiments provide for efficient encoding and rendering of remote graphic displays by applying one or more of the following: (1) field encoding for identifying fields of a graphics set such that commonalities of various fields across different graphics languages are identified; (2) resource caching, which treats heterogeneous resources in a homogeneous way when it comes to storing them; (3) determining the type of encoding for remoting items within a graphics set based upon the types of compression mechanisms supported by a remote device; (4) improving responsiveness by rendering with partially sent resources; (5) a mechanism for determining what portions (if any) of a graphics set should be sent to a remote device and in what order; and (6) use of dedicated resources already on a remote device in order to eliminate the transfer of a resource between a local device and the remote device when rendering such resource.

  • Patent number: RE45692
    Abstract: An automatic focusing apparatus performs focusing using a first automatic focusing method in which lens drive control is performed based on a focus signal so that a focus lens is moved to an in-focus point, and a second automatic focusing method in which lens drive control is performed based on information corresponding to an object distance so that the focus lens is moved to an in-focus point. The direction in which the focus lens is moved to the in-focus point according to the second automatic focusing method is compared with the direction in which the focus lens is moved to the in-focus point according to the first automatic focusing method. Based on the result, it is determined whether to perform the lens drive control according to the second automatic focusing method.

  • Patent number: RE45860
    Abstract: A monitor control system capable of reprogramming the function of a LCD monitor. The monitor control system utilizes VGA signal lines for video signal transmission during normal mode of operation and the same VGA signal lines for transmitting erase/record commands and data when the erasable programmable ROM inside the monitor demands reprogramming. Using an isolator circuit in the monitor control system for isolating an erase/record pathway of an erasable programmable ROM from a normal video pathway, data within the erasable programmable ROM can be modified without opening up the monitor casing. Hence, the modification of monitor function is much more convenient.

  • Patent number: RE47152
    Abstract: Technologies are described herein for altering the appearance of a digital image using a shape. A mask edit mode of operation is provided in which an application program displays a mask shape superimposed on a digital image. The application program also provides user interface controls for altering the size, position, and rotation of the digital image independently of the mask shape, and user interface controls for altering the size, position, and rotation of the mask shape independently of the digital image. When a cropping request is received, the portion of the digital image within the mask shape is mapped onto the mask shape, thereby creating a mask-cropped shape, and a normal editing mode is entered. In the normal editing mode a set of user interface controls is provided for modifying the size, position, and rotation of the mask-cropped shape.
