The invention relates to an aluminum alloy strip with improved surface optics, which is fabricated via hot and/or cold rolling, and consists of a type AA 3xxx, AA 5xxx, AA 6xxx or AA 8xxx aluminum alloy. The object of proposing an aluminum alloy strip that is suitable for attractive and precious surface optics despite the elevated percentage of alloy constituents is achieved in that, after degreasing, the finish-rolled aluminum alloy strip exhibits an increase in the luminance value L*(ΔL) in relation to the rolled-greasy state of more than 5 while measuring the color of the surface in the CIE L*a*b* color space using a standard illuminant D65 and a normal observation angle of 10°, excluding direct reflection in 45°/0° geometry.

Displays having calibrators are disclosed. An example display includes a sensor to measure a plurality of readings for color settings of a color pattern presented by the display. A processor is to calculate average values corresponding to respective ones of the plurality of readings for the color settings. A calibration manager is to generate calibrated measurement values based on the average values. The calibrated measurement values to enable determination of color space information for the display.

An information processing device includes a processor configured to acquire image data including color information, acquire color information of a formed image, the formed image being an image formed on a recording medium on a basis of the image data, acquire light transmittance information expressing a degree of light transmittance of an image-carrying medium, the image-carrying medium being the recording medium on which the formed image is formed, and associate first color information, second color information, and the light transmittance information with each other, the first color information being the color information included in the image data and the second color information being the color information of the formed image.

There are procedures typically used in auto body shops to assist in matching a proposed paint mix with that on undamaged portions of the vehicle. A test panel is taped to a stick and arranged next to the panel to be matched at a couple of angles. The present procedures are unrepeatable and often utilize two individuals. According to embodiments of the present disclosure, a wand has a test panel portion with embedded magnets. The test panel is attracted to the test panel portion via the magnets and the wand holds onto the vehicle panel also via the magnets. The lower side of the test panel portion that sits against the vehicle has at least two flat surfaces at different angles so that the wand can be placed on the surface of the vehicle, or other surface, to assess the paint match from the different angles.

In a colorimetric device and a colorimetric method according to the present invention, chart definition information including at least patch position definition information representing each position of a plurality of patches in a color chart is stored, patch position measurement information representing the position of the patch is obtained on the basis of an image of the color chart, patch position correction information is obtained by correcting the patch position measurement information on the basis of the chart definition information, and then, each color of the plurality of patches is measured in each of the positions of the plurality of patches represented by the patch position correction information.

A technique of determining the presence of a species in a sample may include passing light through an optical filter. In an example, the optical filter may include a spatially variant microreplicated layer optically coupled to a wavelength selective filter. The wavelength selective filter may have a light incidence angle-dependent optical band. The spatially variant microreplicated layer may be configured to transmit light to a first optical region of the wavelength selective filter at a first predetermined incidence angle and to a second optical region of the wavelength selective filter at a second predetermined incidence angle.
