  • Patent number: 6924840
    Abstract: A color image capturing device provided with groups of two rows of photoelectric conversion elements for each color of R, G and B is mounted on a carriage and planar color images are read by moving the carriage in a sub scanning direction. As each first row of photoelectric conversion elements and each second row of photoelectric conversion elements are offset from each other by an amount equivalent to a half of the width of an individual element in a main scanning direction, and resolution in the main scanning direction is enhanced. As each row of photoelectric conversion elements is arranged at pitch equivalent to the height of four rows, all the rows of photoelectric conversion elements can read the same line, even if the carriage is moved at speed twice or four times as fast as that in reading at 600 dpi to read at the resolution of 300 dpi or 150 dpi in the sub scanning direction at high speed in case the reading resolution of each row of photoelectric conversion elements is 600 dpi.

  • Patent number: 6914628
    Abstract: Conventionally, in image processing using a smoothing filter, the large amount of calculation for 25× the number of pixels takes much processing time. A computer 21 as the nucleus of image processing determines whether or not a pixel of interest is a color blur pixel, based on the intensity of a low-density element color, at steps S130 and S140. If the pixel is a color blur pixel, the computer 21 determines whether or not the color blur pixel is an edge pixel at step S150. If the pixel is not an edge pixel, the computer 21 uses a smoothing filter at step S152, while if the pixel is an edge pixel, the computer 21 uses a median filter at step S154, in image processing to reduce the color blur. This reduces the amount of calculation and realizes high-speed image processing.

  • Patent number: 6912004
    Abstract: A method and a system for processing images using interpolating. A variation value for different sets of pixels is determined, and the set of pixels with the highest correlation (lowest numeric value) is selected. A missing color at a given pixel is expressed in terms of the information contained in the selected set of pixels. If the variation value is below a certain threshold, due to noise or other factors, an alternative set of pixels using a different variation method may be selected. The missing color is estimated as a weighted sum of, e.g., the green samples divided by the weighted sum of, e.g., the red samples multiplied by the sampled value from the pixel to be estimated.

  • Patent number: 6894723
    Abstract: A ranking-based automatic dark compensation circuit for efficiently estimating dark level in a CCD or CMOS image sensor. The ranking circuit comprises of k staggered comparators, each comparator having an associated temporary result register. Each comparator having two inputs, with the first input coupled to an output of the previous stage comparator and the second input coupled to its associated temporary result register. The temporary results are initialized to the largest possible dark value. At each stage, a comparison is made of a new input sample to a stored value of the temporary register. If the new sample is greater than the value of the associated temporary register, the value in temporary register is not changed and the new sample is passed to the next comparator. Conversely, if the new sample is smaller, then that new sample is stored into the temporary register, while the original temporary result is passed to the next comparator.

  • Patent number: 6891570
    Abstract: In a method for determining the frame rate and exposure time for each frame of a video collection, an image capture system acquires at least two successive frames of a scene, separated in time. The two images are compared to determine if objects in the scene are in motion. If motion is detected, then the speed and displacement of the objects that are moving is determined. If the speed of the fastest moving object creates an unacceptable amount of image displacement, then the frame rate for the next frame is changed to one that produces an acceptable amount of image displacement. Also, if the speed of the fastest moving object creates an unacceptable amount of motion blur, then the exposure time for the next frame is changed to one that produces an acceptable amount of motion blur.
