According to one aspect, an imaging device analysis method includes receiving initial light comprising a plurality of wavelengths of light, filtering some of the wavelengths of the initial light forming a plurality of light beams comprising different wavelengths of light, after the filtering, optically communicating the light beams of the different wavelengths of light to an imaging device, receiving the light beams using the imaging device, and analyzing the imaging device using light, wherein the light beams comprising the different wavelengths of light are emitted beams after the receiving.
Abstract:
The system provides for controlling color reproduction of input color image data in a network having nodes (or sites). The system distributes the input color image data from one of the nodes to other nodes, and provides data structures in the network. The system has means for providing color calibration data at each node characterizing output colors (colorants) of the rendering device of the node, and means for producing at each node, responsive to the color calibration data of the rendering device of the node, information for transforming the input color image data into output color image data at the rendering device of the node. The rendering device of each node renders a color reproduction responsive to the output color image data, wherein colors displayed in the reproduction at the rendering device of each node appear substantially the same within the output colors attainable by the rendering devices.

An image capturing device includes a sensor unit that captures a predetermined range including a subject; a reference chart that is captured by the sensor unit together with the subject; an illumination light source that illuminates the subject and the reference chart; a lens member including one or more lenses arranged in an optical path of reflected light extending from the subject and the reference chart to the sensor unit; and a lens moving unit that moves at least one lens of the lens member so as to change a position thereof in a direction along the optical path.
Abstract:
In a color imaging system, multiple rendering devices are provided at different nodes along a network. Each rendering device has a color measurement instrument for calibrating the color presented by the rendering device. A rendering device may be a printer in which the measuring of color samples on a sheet rendered by the printer is provided by a sensor coupled to a transport mechanism which moves the sensor and sheet relative to each other, where the sensor provides light from the samples to a spectrograph. A rendering device may also be a display having a member supporting a color measuring instrument for receiving light from an area of the screen. The color measuring instruments provide for non-contact measurements of color samples rendered on a display or a sheet, and are self calibrating by the use of calibration references.
