  • Patent number: 8681228
    Abstract: A device includes a display monitor configured to display on a screen of the display monitor at least one of a current image and a preceding image taken by an optical unit, a storage unit configured to store the preceding image, and a control unit configured to display a part of the preceding image on the screen when the current image is displayed on the screen, the displayed part of the preceding image indicating a positional relationship between the current image and the preceding image. The current image is taken when the displayed part of the preceding image substantially overlaps a corresponding portion of the current image such that the current image and the preceding image can be processed to form a panoramic image.

  • Patent number: 7298919
    Abstract: A camera system includes a display monitor which displays an image of an object, taken by an optical unit, on a screen of the monitor. A reading unit reads a preceding image and a current image among a plurality of partially overlapping images, from a memory device, the preceding image and the current image containing a common element. A determining unit determines a positional relation between the preceding image and the current image based on a common pattern derived from the common element in the two adjacent images read by the reading unit. A displaying unit displays an image indicating a boundary of the preceding image on the screen of the monitor at a shifted position according to the positional relation determined by the determining unit, with the current image concurrently displayed on the screen of the monitor.

  • Patent number: 7271803
    Abstract: A 3-D visual simulating system stores image data sets in a predetermined viewing space for right and left visual field and selects a portion of the stored image data corresponding to the current visual field for displaying it to an observer. The 3-D image stimulus changes according to the current visual field of the observer and the location of the observer in a predetermined visual space in a manner that undesirable perceptional effects are substantially eliminated. The image data sets are stored in a reduced space in an efficient manner for retrieval.

  • Patent number: 7182464
    Abstract: A project is often positioned so that its optical axis is at an imperfect orthogonal angle with respect to a projection screen. This position causes a keystone distortion as well as imperfect focus in the projected image. To correct these undesirable problems, initially, a lens and/or an image-forming plate is independently repositioned to bring the projected image into focus based upon user input data. The keystone distortion is also corrected by redrawing the image on an image-forming surface based upon additional user input data.

  • Patent number: 6948654
    Abstract: A data sheet is composed of an upper part and a lower part. The upper part is used as a user interface including a reduced image of contents of a document. The lower part is an interface for a reading device such as a copy machine, including a code obtained by encoding the document. By use of the data sheet, the user can easily distribute or carry an electronic document data with the user. In addition, the user can recognize contents of the electronic document data by looking at the reduced image printed on the data sheet.
