摘要： An imaging device for generating a digital image of a scene comprises an image sensor, an optic, and one or more actuators. The image sensor comprises an array of photosensors. The optic is operative to at least partially direct light rays from the scene onto this image sensor so that an image of the scene is created on the image sensor. The one or more actuators are operative to move at least one of the image sensor and the optic while the digital image is generated so that the incoming light rays from the scene are distributed over the photosensors of the image sensor in such a way as to limit spatial frequencies in the image of the scene created on the image sensor to values below a Nyquist frequency of the image sensor.

摘要： Method and apparatus are disclosed for providing Moire distance and displacement measurements of a diffusely reflective surface of an object or support. More particularly, a first grating is physically located, formed, or printed on the diffusely reflective surface. An image of the first grating is formed on a second grating by an imaging means for generating a Moire pattern behind the second grating. At an initial position of the diffusely reflective surface relative to the imaging means, the periods of the image of the first grating and the second grating match. Movement of the diffusely reflective surface in a direction normal thereto and away from the initial position produces a spatially varying intensity pattern caused by the Moire between a shifting and changing magnified pattern of the image of the first grating and a pattern of the second grating. The temporal intensity changs in the Moire pattern are detected and are used to produce information related to the instantaneous distance and displacement of the diffusely reflective surface from the initial position.

摘要： In a parallax correction method and system, corresponding regions of first and second digital images of the same subject are upsampled to provide a pair of upsampled regions. The corresponding regions have parallax. The upsampled regions are statistically compared at a plurality of relative subpixel offsets to provide a corresponding plurality of similarity values. The similarity values define a peak similarity value and a corresponding peak subpixel offset among the plurality of relative subpixel offsets. The second digital image is shifted relative to the first digital image by the peak subpixel offset.

摘要： A highly uniform infrared illumination source for illuminating a stripe of a moving sensitized web for line scan imaging of imperfections in the coating on the web by a CCD imaging camera. A light integrator having an elongated housing formed with side and end walls defines a linear light integrating cavity having diffusely reflecting interior wall surfaces. An elongated array of infrared LEDs is spaced along the side wall for emitting light into the cavity for integration within the cavity. A longitudinally extending slit is formed in the side wall through which a diffuse, linear light beam exits the elongated slit having a varying longitudinal intensity profile. The intensity of the light emitted by the LEDs is modulated in an intensity pattern that alters the varying longitudinal intensity profile of the linear light beam to provide a desired longitudinal intensity profile of the stripe of diffuse illumination. Preferably, the intensity modulation renders more uniform the longitudinal intensity profile of the linear light beam illuminating the web as viewed by the imaging camera. The desired light intensity profile along the length of the emitted light beam is achieved by clustering the LEDs with LED drive circuits operated at different drive currents as a function of a set point control signal appropriate to the characteristics of the imaging camera and a transmitted light intensity feedback signal to maintain the intensity pattern of the LEDs and the uniform intensity profile as viewed by the imaging camera regardless of the optical density of the web.

摘要： An apparatus for imparting a controlled relative displacement of two parallel surfaces along a single axis or along two orthogonal axes is disclosed. Controlled displacement along any axes, orthogonal or otherwise, may be obtained by stacking appropriately oriented single-axis units. The apparatus uses a force-generating means and connecting beams acting in concert to produce a relative displacement of two rigid parallel frames. An imaging means is mounted on one rigid frame and a photosensitive matrix on the other to provide an electro-optical detector system in which the image field may be periodically displaced along a closed trajectory to cover the interstices between the detector elements of the photosensitive matrix. A method for the use of the apparatus to generate electronic picture information is also disclosed.
