Abstract: A scannerless range imaging system includes an illumination system and an electromechanical light modulator. The illumination system illuminates objects in the scene with modulated illumination of a predetermined modulation frequency, and the modulated illumination reflected from objects in the scene incorporates a phase delay corresponding to the distance of the objects from the range imaging system. The electromechanical light modulator, which is positioned in an optical path of the reflected illumination, operates at a reference frequency that corresponds to the predetermined modulation frequency and accordingly modulates the modulated illumination reflected from the object, thereby generating a phase image from the interference between the reference frequency and the reflected modulated illumination. The system further includes an optical system that deflects the reflected illumination to the electromechanical light modulator and redirects the phase image generated by the electromechanical light modulator to an image capture section. A color image may be captured by moving the optical system out of the optical path such that reflected illumination from the object will pass directly to the image capture section without contacting the electromechanical light modulator.

Abstract: A panoramic image capture aid is formed in a photographic camera to assist a photographer in recording a series of film images that can be combined to form a panoramic image. The capture aid includes a viewing window on the camera, a first stripe indicator coupled to a film advance mechanism for moving with each film advance, and a second stripe indicator coupled to a compass for indicating the direction the camera is pointing. The first and second stripe indicators are supported on transparent rings concentrically arranged relative to the camera body such that their stripes intersect in the viewing window when the camera is properly positioned for the next image in the series of images.

Abstract: Method and associated apparatus for positioning a thermal donor media, having a plurality of transfer panels, each having a transfer area that is greater than the total area of a number of receiving media, such that a single transfer panel can provide an area of donor exclusively to each of the number of receiving media. The dimensions of unused areas of the thermal donor media are matched with the dimensions of the next to-be-printed image to enable a transfer printing to take place at an area that has dimensions that are equal to or greater than that required for the printed image. When an available area is identified the thermal donor media is moved into alignment and the transfer takes place. In one embodiment of the invention the thermal donor media is in the form of a ribbon that is wound between driven spools to bring unused areas into vertical printing alignment with the receiving media and the receiving media is displaced transverse to the ribbon to provide a horizontal alignment.

Abstract: A transaction card is described in which data representing an identifiable image can be stored in a limited amount of storage space. The image to be stored is converted to an associated matrix of pixel values. The matrix of pixel values is partitioned into a plurality of ordered image portions corresponding to a like partitioning of the image. The partitioning is generally related to feature locations in the image. Each image portion is compared with a reference set of image portions represented by pixel groups. Associated with each pixel group is a signal group. For each image portion, a signal group is chosen for the associated reference pixel group that most closely matches with the pixel image portion. The signal groups representing the matrix of pixel values or the image to be stored are stored as bit patterns on the storage space of a transaction card. The bit patterns may then be read and converted to the signal groups. From the signal groups, a reference pixel group is identified from within a reference set and the reference pixel group is positioned with respect to the image at the same location as the image portion. Using this technique, a recognizable image can be constructed from image information compatible with the ISO-7811/2 standards.

Abstract: A method and apparatus for generating a color mapping for a dental object. The method includes generating a transformation matrix according to a set of spectral reflectance data for a statistically valid sampling of teeth. Illumination is directed toward the dental object over at least a first, a second, and a third wavelength band, one wavelength band at a time. For each of a plurality of pixels in an imaging array, an image data value is obtained, corresponding to each of the at least first, second, and third wavelength bands. The transformation matrix is applied to form the color mapping by generating a set of visual color values for each of the plurality of pixels according to the obtained image data values and according to image data values obtained from a reference object at the at least first, second, and third wavelength bands. The color mapping can be stored in an electronic memory.
