Abstract:
An image forming apparatus includes an image forming unit configured to form a measurement image on a sheet, a measurement unit configured to irradiate the measurement image with light and measure light reflected from the measurement image, a white reference plate arranged to be movable to a first position opposed to the measurement unit and a second position separated farther from the measurement unit than the first position, a shielding unit arranged to be movable to a third position that blocks the light with which the measurement unit irradiates the white reference plate and a fourth position that does not block the light, and a control unit configured to control positions of the reference plate and the shielding unit. When the measurement unit measures the white reference plate, the control unit moves the shielding unit to the fourth position and the white reference plate to the first position.
Abstract:
A modular device includes base and color sensing portions. The color sensing portion has a face, a controlled light source having a first channel between the light source and the face, and a color sensor arranged at a distal end of a second channel. The color sensor receives light reflected from the target surface and generates output signals representative of a surface color. The first and second channels extend at least 45 degrees apart from each other and respective to the face. The base portion communicates with the color sensor and a user interface enabling control input for the color sensor. The program further receives the output signals from the color sensing device and displays a first image of the detected color, and displays a second image of a user-selected color beside the first image. Color data values are further displayed corresponding to the difference between displayed colors.
Abstract:
A system mounted in a vehicle for classifying light sources. The system includes a lens and a spatial image sensor. The lens is adapted to provide an image of a light source on the spatial image sensor. A diffraction grating is disposed between the lens and the light source. The diffraction grating is adapted for providing a spectrum. A processor is configured for classifying the light source as belonging to a class selected from a plurality of classes of light sources expected to be found in the vicinity of the vehicle, wherein the spectrum is used for the classifying of the light source. Both the image and the spectrum may be used for classifying the light source or the spectrum is used for classifying the light source and the image is used for another driver assistance application.
Abstract:
A device includes a processor configured to execute a process including extracting a pixel value of each of a plurality of areas of a same color that are arranged at different positions on a color chart that is captured in an image, and specifying by using the extracted pixel values of the areas and arrangement positions of the areas of the same color an area that has a pixel value that corresponds to a function that expresses fluctuation of pixel values according to a position due to non-uniformity of an illumination environment that fluctuates the pixel values at a constant rate in one direction, and correcting a pixel value of a correction target area between the areas of the same color according to the pixel value of the specified area.
Abstract:
A pH detecting device includes a supplying unit to supply a pH indicator, with an inkjet head, to a surface of a material to be processed on which acidification is performed; a color information detector to detect color information of the pH indicator supplied to the surface of the material; and a pH specifying unit to specify a pH value of the surface of the material based on the color information.
Abstract:
A colorimeter, webcam, camera, spectrophotometer, scanner or other instrument measures the color composition and conditions and texture of a person's body part or presented beauty product and an individual custom formulation is produced. A presented beauty product may include foundation, concealer, tinted moisturizer, primer, skin care products, blush, nail polish, hair dye, lipstick, lip gloss, mascara, eye liner and eye shadow. The produced custom formulation may comprise foundation, concealer, tinted moisturizer, primer, skin care products, blush, nail polish, hair dye, lipstick, lip gloss, mascara, eye liner, eye shadow or other consumer products. A computer system 301 includes a processor 501 and a non-transitory, computer readable medium 500 containing machine readable instructions that accept data from a colorimeter 300 or like instrument and uses a main executable program 502 and a subroutine 504 for color analysis.
Abstract:
A high efficiency thermal printing system, comprising: a donor ribbon having donor material; a receiver medium; a test pattern to be printed on the receiver medium using the donor ribbon; a print head, a sensor, and a processor is disclosed. The present invention is adapted to print the test pattern on the receiver medium by heating the donor ribbon to cause the donor material to transfer from the donor ribbon onto the receiver medium, thereby depleting donor material on the donor ribbon. Moreover, the sensor is adapted to measure a depletion amount of the donor material on the donor ribbon after printing the test pattern, and the processor is adapted to calibrate the thermal printing system by adjusting a lookup table in response to the measured depletion amount of donor material.
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.

Abstract:
Techniques related to printing are described herein. According to an example, color patches are to be printed on a substrate. The substrate can be positioned on a substrate support for operation of a color sensor in a color measurement zone. Dimension and location in the substrate of the color patches are selected such that, for each color patch, at least a portion of the color patch can be positioned on a support projection in the color measurement zone. In some examples, color analysis techniques are described.
