  • Patent number: 7023576
    Abstract: A digital image processing method for eliminating Moiré in a digital image divided into pixels holding pixel component values includes selecting a first pixel and defining a pixel window around the selected first pixel. Then, a set of pixels are identified which consist of pixels within the window that have pixel component values within a pixel component value range that is related to the selected first pixel. A pixel component value is calculated based on corresponding pixel component values of pixels in the set of pixels and then this calculated pixel component value is allocated to the selected first pixel.

  • 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: 6658203
    Abstract: An imaging system and method which successively records parts of a single frame image compensates for variations in intensity of an illuminating source such that the recorded single frame image appears to have been generated by a substantially temporally constant light intensity. This compensation allows inexpensive light sources and detectors to be employed.

  • Patent number: 5999661
    Abstract: An image processing system and method for processing a source digital image with a first energy sensitivity parameter value and including first pixels of first pixel values into a target digital image with a selected second energy sensitivity parameter value and including second pixels of second pixel values, for enabling a photographer to adjust resolution and sensitivity of a digital image to correspond to the light sensitivity of a specific photographic film. Thus, the photographer can use a light meter to indicate pairs of exposure time and diaphragm settings for the electronic camera that will ensure a correct exposure of the digital image when the light meter is set to indicate correct pairs of exposure time and diaphragm settings for a camera.

  • Patent number: 5960153
    Abstract: An image recording system comprising an electronic camera and an image recording method are provided by which influence of a recorded image of temporal fluctuations in intensity of light illuminating objects to be recorded is significantly reduced so that use of inexpensive light sources for illumination of the objects is possible.
