  • Patent number: 7791657
    Abstract: An imaging system implementing a scheme for enhancing the dynamic range of the device. An array of radiation detecting pixels produces an output in response to a stimulus. The signal from each pixel is read once for evaluation. If the voltage at an individual pixel satisfies a programmed condition, such as exceeding a predetermined threshold voltage at a particular time, that pixel is reset and begins producing an output signal anew. If the pixel output signal does not satisfy the condition, it is allowed to continue producing the signal without being reset. After the evaluation read, all of the pixels are then read row by row into a buffer and digitally processed. A memory register tracks which pixels have been reset, and the corresponding output signals are adjusted accordingly. This scheme allows the system to process input signals across a broader range of intensity without losing information due to pixel saturation or sacrificing sensitivity.

Face-image detection processing is applied to the frames of the subject images ?1 and ?2 to detect face-image areas C1, C2 and C3. The face-image area C2 is construed to be linked to the face-image area C1, which is the corresponding face-image area. Since a face-image area that corresponds to the face-image area C3 does not exist, the face-image area C3 is construed as not being linked. The linked face-image area C2 in the Nth frame of the subject image ?2 is decided upon as a face-image area. Thus, face areas can be decided with comparatively good accuracy.

  • Patent number: 7612869
    Abstract: A system and method for determining instantaneously the three-dimensional coordinates of large sets of points in space is disclosed. This system uses two or more CCD cameras (or any other type of camera), each with its own lens and pinhole. The CCD's are all arranged so that the pixel arrays are within the same plane. The CCD's are also arranged in a predefined pattern. The combination of the multiple images acquired from the CCD's onto one single image forms a pattern, which is dictated by the predefined arrangement of the CCD's. The size and centroid on the combined image are a direct measure of the depth location Z and in-plane position (X,Y), respectively. The use of a predefined pattern enables high speed computation through simple algorithmic procedures. Moreover, the use of CCD cameras allows for the recording of such datasets at the corresponding image frame rate, thus opening the use of the invention to the mapping of dynamical systems.

  • Publication number: 20090268983
    Abstract: A digital imaging system and method using multiple cameras arranged and aligned to create a much larger virtual image sensor array. Each camera has a lens with an optical axis aligned parallel to the optical axes of the other camera lenses, and a digital image sensor array with one or more non-contiguous pixelated sensors. The non-contiguous sensor arrays are spatially arranged relative to their respective optical axes so that each sensor images a portion of a target region that is substantially different from other portions of the target region imaged by other sensors, and preferably overlaps adjacent portions imaged by the other sensors. In this manner, the portions imaged by one set of sensors completely fill the image gaps found between other portions imaged by other sets of sensors, so that a seamless mosaic image of the target region may be produced.

  • Publication number: 20090225203
    Abstract: A compound-eye imaging device comprises an imaging device body having 9 optical lenses and a solid-state imaging element for imaging unit images formed by the optical lenses. Assuming that the combination of each of the optical lenses with a corresponding divided area of the solid-state imaging element to image each of the corresponding unit images is an imaging unit, thereby forming multiple imaging units, the respective imaging units have randomly different optical imaging conditions. For example, the focal lengths of the 9 optical lenses are set to have random values in which the optical lenses are arranged to have random distances between adjacent ones thereof in a direction parallel to the major surface of the solid-state imaging element. This compound-eye imaging device substantially prevents unit images formed by respective imaging units from being the same, making it possible to easily increase the definition of a reconstructed image.
