  • Patent number: 7834917
    Abstract: Noise reduction is performed on the basis of characteristics of an image in a detection range. A noise reduction block 4? performs a second-order differentiation process and a symmetry process to decide adjacent pixels with which noise reduction is preformed for an attention pixel. With the pixel level of the attention pixel in the detection range and the pixel levels of adjacent pixels used for noise reduction, an arithmetic mean processing section 16 calculates a mean value. A median filter 17 selects a median value. With the number of pixels used for noise reduction, it is determined whether the image in the detection range contains a flat portion, a ramp portion, or an edge. The mean value and the median value are weight-added with a weighted coefficient that are changed on the basis of characteristics of the image. The result is substituted for the level of the attention pixel.

  • Patent number: 7830431
    Abstract: A new method of reading an imager is achieved. The method comprises providing an imager array comprising n rows and m columns where a pair of rows can be read during a single row access time. A first image field is completed by sequentially reading and storing pixel values of pairs of adjacent rows of the imager array. The reading begins at a first row, and the reading stops when less than three rows are unread. Thereafter pixel values of the next row are read and not stored. Thereafter pixel values of the first row of the imager array are read and not stored. A second image field is completed by sequentially reading and storing pixel values of pairs of adjacent rows. The reading begins at the second row, the reading stops when less than two rows are unread.

  • Patent number: 7808532
    Abstract: A flash-based strategy is used to separate foreground information from background information within image information. In this strategy, a first image is taken without the use of flash. A second image is taken of the same subject matter with the use of flash. The foreground information in the flash image is illuminated by the flash to a much greater extent than the background information. Based on this property, the strategy applies processing to extract the foreground information from the background information. The strategy supplements the flash information by also taking into consideration motion information and color information.

    Abstract: The present invention relates to imaging systems that generally include at least a first substrate, on which a charge coupled device imaging sensor array is formed, and a second substrate on which readout circuitry is formed. Information related to the amount of light incident on pixels included in the imaging sensor array is passed to the readout circuitry as a voltage signal over an interconnection between the imaging sensor array and the readout circuitry. Accordingly, the readout circuitry may sample the output of the imaging sensor array multiple times. The system allows different processes to be used for forming the imaging sensor array and the readout circuitry, while also supporting multiple samples of information provided by the imaging sensor array.

  • Patent number: 7791658
    Abstract: A versatile analog front end and timing generator (AFE/TG) integrated circuit has output modes wherein multiple identical AFE/TGs output digitized sensor data to a single digital image processor (DIP) without intervening discrete multiplexing circuitry. In one embodiment, the AFE/TG is operable in either a bit slice mode or a time slice mode. In the bit slice mode, each of the multiple AFE/TGs sections up a word of pixel information into subsets of bits, and then communicates the subsets in parallel, one subset after another, across point-to-point connections to corresponding terminals of the DIP. The DIP captures the subsets of bits, and reassembles the subsets to recreate the word of pixel information. Each of the multiple AFE/TGs communicates words of pixel information to a different set of terminals on the DIP in this way, thereby avoiding timing complications, loading and/or expense associated with communicating the pixel information using time multiplexing techniques.
