  • Method for Spectral Integrated Calibration of an Image Sensor by Means of a Monochromatic Light Source
    Publication number: 20080212874
    Abstract: A method of spectral integrated calibration of an image sensor (6) in an image-recording instrument (1). The image sensor (6) is illuminated with a plurality of predetermined light spectra, preferentially by monochromatic light-sources. The method includes the following steps: providing an image-recording instrument (1) having a device, integrated therein, for providing the plurality of predetermined light spectra, and illuminating the image sensor (6) with the plurality of predetermined light spectra of the device. In addition, an image-recording instrument (1) with an image sensor (6), said image-recording instrument (1) including a device that, for the purpose of spectral calibration of the image sensor (6), provides a plurality of predetermined light spectra with which the image sensor (6) is capable of being illuminated.

  • Process and target for calibration of digital input devices
    Patent number: 7253921
    Abstract: The invention is about a process to calibrate digital input devices, especially scanners and digital cameras. An input device reads a calibration picture and an adjustment of color values is made. This is defined through the usage of a calibration picture that shows only normed, printable colors. The invention is also about a calibration target.
