摘要： A method for correcting colored fringe artifacts in a region of an image around saturated pixels captured by an electronic imager associated with a color filter array, includes providing a threshold map of the image based on thresholding one or more color channels with a common or separate threshold value for each color channel; providing a first edge map by dilating the threshold map as a function of the color fringe width, producing a first dilated threshold map and subtracting the threshold map from the first dilated threshold map; and color-desaturating image pixels that correspond to the first edge map.

摘要： Imaging systems and methods for calibrating imaging systems are provided. The imaging system has a body, a scene image capture system that captures images using a taking lens system that can be set to a plurality of different focus distances, and a rangefinder that is capable of determining a distance between the imaging system and at least one portion of a field of view of the talking lens system. The method comprises: automatically capturing a first calibration image of a first field of view through the taking lens system with the taking lens system set to a first focus distance setting; identifying a portion of the first calibration image having a predetermined degree of focus; using the rangefinder to determine a first calibration distance from the imaging device to the identified portion. A focus correlation is determined based upon the first calibration distance and the first focus distance setting.

摘要： In order to limit the maximum spatial frequency of image light falling upon the array of photosites in an image sensor, an imaging apparatus includes an optical section through which the image light passes and an optical filter including an array of four shaped features placed in mutually spaced relation in the optical section in order to blur the image light and limit the spatial frequencies to values below the Nyquist frequency of the sensor. The optical filter is placed to best effect in the stop of the optical system.

摘要： An integrating cylinder for use as an illuminator for a film scanner includes a hollow cylinder including an inner surface defining a cavity therein and an outer surface, a diffusing layer of reflective material covering an inner surface of the hollow cylinder, a first end plate for sealing a near end of the hollow cylinder, and a second end plate for sealing a far end of the hollow cylinder opposite the near end. The hollow cylinder defines a slit formed parallel to a longitudinal axis of the hollow cylinder between the inner and outer surfaces at a predetermined line along a circumference of the hollow cylinder. The first end plate defines a hole which is decentered from the longitudinal axis of the hollow cylinder and can be tilted at a predetermined angle to the longitudinal axis of the hollow cylinder towards an area of the inner surface of the hollow cylinder. Additionally, the hole is located at a predetermined angular separation around the circumference of the hollow cylinder from the slit for receiving a light beam directed at the predetermined angle to the longitudinal axis into the cavity. After reflections in the cavity, the light emerges from the slit to form a line of uniform diffuse light.
