Systems and methods for determining illumination angle and viewing angle in color observation are described. The system includes an optical capturing device to acquire an image of its surroundings and a processing unit. When operated, the processing unit executes the following steps: identify a position of a light source in the image acquired by the optical capturing device; identify a position of a viewer in the image acquired by the optical capturing device; determine a first angular position of the light source with respect to the optical capturing device and a second angular position of the viewer with respect to the optical capturing device and provide the first angular position and the second angular position to define an actual viewing geometry.

Device and method for determining observation geometry

A system for displaying one or more images to select one or more matching formulas to match color and appearance of a target coating of an article includes a computing device, a display device, a host computer connected to the computing device, one or more data input devices, a first database containing repair formulas, color characteristics, and appearance characteristics, a second database containing identification information of an article or a three-dimensional model of an article or a three-dimensional mapping of a geometry of a part of an article, and a computer program product accessible to the computing device and/or the host computer and performing a computing process to retrieve at least one preliminary matching formula from the first database, select one article or a three-dimensional mapping of a geometry of one article from the second database, generate individual matching images, and display the individual matching images on the display device.

Systems and methods for paint match simulation

The present disclosure is directed to a system for displaying and designing one or more colors on digital display devices, non-digital display media, or a combination thereof. The system can comprise one or more comparative colors, background colors, or a combination thereof for improved color visual comparison. The system can be used for comparing and selecting colors, such as for use in fashion color designs, automotive color designs, architecture color designs, appliance color designs, or a combination thereof. This disclosure is further directed to a kit and a method for displaying and producing one or more colors.

Process for displaying and designing colors

The present invention is directed to a monitoring device for producing a target composition, such as an automotive paint or an architectural paint. The device includes a client computer in communication with a host computer and means for dispensing required items for making a desired amount of the target composition. The computer readable program code means in the computers identify one or more formulas associated with identification criteria of the target composition and dispense through means for dispensing the required items listed in the formula. The code means search for the required items in the various inventories, including updating the inventories if required. The device can be also used to control the inventory by shipping just in time any components required to produce target compositions, such as refinish tints used in automotive refinish paints.

Monitoring device used for producing compositions

The present invention is directed to a system for digital displaying images of various colors and appearances of an article and the use thereof. The invention is particularly directed to a system for displaying images for selecting one or more matching formulas to match color and appearance of an article. The invention is even further directed to a system for displaying images for selecting one or more matching formulas to match color and appearance of a target coating of a vehicle.

System for color match and digital color display

The invention is particularly directed to a method for displaying one or more images to select one or more matching formulas to match color and appearance of an article. The invention is even further directed to a method for displaying one or more images to select one or more matching formulas to match color and appearance of a target coating of a vehicle.

Digital display of color and appearance and the use thereof

An automated computer-controlled method and apparatus for measuring the quality or fineness of a pigment dispersion sample, comprising placing the pigment dispersion at the deep end of the tapered path of a Hegman gage block, placing the Hegman gage block in a holder in a motorized drawdown device that draws the scraper along the length of the tapered path at an angle and to at a contact pressure and at a controlled rate, thereby creating a tapered film sample of paint whose thickness tapers from a maximum thickness of 100 micrometers to a minimum thickness of zero. An illuminator assembly illuminates the sample with a substantially collimated light source at an intensity level and the light reflected from the sample is collected by a lens onto a photodetector array in a digital camera. After a time interval the camera acquires an image of the sample. The image is digitized and stored in a memory in the computer and then a portion of the image within a region of interest corresponding to the sample in the tapered path is analyzed to detect and count pigment agglomerates that protrude above the surface of the sample.

Method and apparatus for quantifying pigment dispersion quality by paint drawdown

A computer-implemented method for displaying on a color display device a realistic color of a paint coating comprising the following steps: (A) identify L*, a* b* color values at least three different angles for a paint coating from a data base; (B) convert the at least three angle L*, a* b* color values to tristimulus X, Y, Z values; (C) develop continuous function equation for each tristimulus X, Y, Z values vs. aspecular angle via computer implementation and calculate the range of angles to be displayed; (D) calculate a range of aspecular angles required to display the object; (E) calculate R,G,B values from tristimulus values over the range of aspecular angles and determine maximum saturation of R,G,B values and bring into range allowed by color display device; (F) determine statistical texture function of paint coating to be simulated; and (G) apply statistical texture function to the R,G,B values of step (E) and display color pixels on color display device to show realistic color of paint coating.

Realistic video color display

An image analysis method to quantify visual showthrough of printed images on the reverse face of planar objects, such as paper. An illumination level is set using a white reference object. A white reference image is stored in a computer memory. An image of a planar object having a printed image on the reverse face is stored in a computer memory. A pixel by pixel ratio of the two images is calculated and a mean value of the ratios is calculated to characterize the visual showthrough. The measurements are substantially independent of both the illumination level and image shading.

Method and apparatus for quantifying visual showthrough of printed images on the reverse of planar objects

The present invention is directed to a process for monitoring production of a target composition, such as an automotive paint or an architectural paint and a monitoring device used therein. The process includes (a) identifying one or more formulas associated with identification criteria of the target composition, the formula providing a required inventory for making a desired amount of the target composition; (b) generating a current inventory; (c) terminating the process if the current inventory does not match with a stored inventory; or (d) continuing the process if the current inventory matches with the stored inventory. The process further comprises (d1) comparing the current inventory against the required inventory to ascertain whether said current inventory fulfills said required inventory; (d2) generating a supplementary inventory if the current inventory partially fulfills the required inventory; (d3) dispensing required items listed in the required inventory from current items listed in the current inventory, supplementary items listed in the supplementary inventory, or a combination thereof to make the desired amount of the target composition; and (d4) generating an updated inventory. The process can be also used to control the inventory by shipping just in time any components required to produce target compositions, such as refinish tints used in automotive refinish paints.

An improved image analysis method to quantify uniformity of visual appearance of planar objects. The measurements are substantially independent of both the image shading and the overall lightness differences among the objects.
