Abstract: Color calibration of color image rendering devices, such as large color displays, which operate by either projection or emission of images, utilize internal color measurement instrument or external color measurement modules locatable on a wall or speaker. A dual use camera is provided for a portable or laptop computer, or a cellular phone, handset, personal digital assistant or other handheld device with a digital camera, in which one of the camera or a display is movable with respect to the other to enable the camera in a first mode to capture images of the display for enabling calibration of the display, and in a second mode for capturing image other than of the display. The displays may represent rendering devices for enabling virtual proofing in a network, or may be part of stand-alone systems and apparatuses for color calibration. Improved calibration is also provided for sensing and correcting for non-uniformities of rendering devices, such as color displays, printer, presses, or other color image rendering device.

Abstract: An optical characteristic measuring apparatus and an optical characteristic measuring method of the invention are an optical characteristic measuring apparatus and method for obtaining a predetermined optical characteristic such as a color value or a total spectral radiation factor of a measurement object. A spectral intensity distribution of predetermined ambient light entering through a measurement opening is measured and stored prior to measurement of the optical characteristic. In measuring the optical characteristic, an optical characteristic in a condition that actually measured ambient light is used as an observation light source is obtained, with use of the stored spectral intensity distribution of ambient light.

The method includes generating a transformation matrix according to a set of spectral reflectance data for a statistically valid sampling of teeth. Illumination is directed toward the dental object over at least a first, a second, and a third wavelength band, one wavelength band at a time. For each of a plurality of pixels in an imaging array, an image data value is obtained, corresponding to each of the at least first, second, and third wavelength bands. The transformation matrix is applied to form the color mapping by generating a set of visual color values for each of the plurality of pixels according to the obtained image data values and according to image data values obtained from a reference object at the at least first, second, and third wavelength bands. The color mapping can be stored in an electronic memory.

Abstract: A method including the determination of color information of an object is disclosed. Data is generated of the object with an image generation device having a field of view. The object and a reference implement having one or more regions of predetermined optical properties are positioned in the field of view of the image generation device. Data is generated of the reference implement, which includes a positional location attribute. Based on the positional location attribute a position of the one or more regions of predetermined optical properties of the reference implement in the field of view of the image generation device is determined by a processing system without operator identification of the position of the reference implement in the field of view of the image generation device. Color information of the object is generated by adjusting the data generated of the object based on the data generated of the reference implement. The color information may include value, chroma and hue information, RGB values, XYZ coordinates, or Lab values. The color information may be transmitted electronically to a remote location. The object may be human skin. The object and the reference implement may be positioned so as to be subject to a substantially corresponding lighting condition.

Abstract: A spectral colorimetric apparatus includes a housing which includes a side wall. An outer surface of the side wall is an adjustment surface capable of adjusting a position of a linear sensor by moving while attaching the linear sensor to the adjustment surface. The linear sensor is supported by the side wall of the housing while abutting on the adjustment surface and receives alight beam that is dispersed by a concave surface reflection type diffraction element and passes through an opening portion. The adjustment surface is parallel to a tangential line at a part of a Rowland circle of the concave surface reflection type diffraction element, through which a light beam received by the linear sensor passes.
