Abstract: A spectroscopic measurement device includes a light receiving element that receives light and outputs a light receiving signal, a variable amplification circuit that amplifies the light receiving signal which is input, and a dark voltage correction unit that calculates a correction coefficient that is a rate of change of a dark voltage value with respect to gains, based on an output value of the variable amplification circuit with each value of two or more gains which are equal to or greater than a predetermined value in an environment where no light is incident on the light receiving element.

Abstract: An inspection method includes: a first acquisition step of acquiring information in which information on a color difference with respect to a reference color is assigned to each of a plurality of first divided regions into which an reference image is divided; a second acquisition step of acquiring information in which information on a color difference with respect to the reference color is assigned to each of a plurality of second divided regions into which a captured image is divided; a first comparison step of comparing the information on the color difference of each of the first divided regions with the information on the color difference of each of the corresponding second divided regions; and a second comparison step of comparing the information on the color difference of each of the first divided regions with the information on the color difference of each of the second divided regions in a combination different from the combination in which the comparison is performed in the first comparison step, and whether reference image data and the captured image data match each other is determined based on a first comparison result obtained in the first comparison step and a second comparison result obtained in the second comparison step.

Abstract: An inspection method includes: spectroscopically separating light from a predetermined imaging range of an inspection object into light of a plurality of wavelengths and imaging spectroscopic images of each of the wavelengths; inspecting a shape of the inspection object using the spectroscopic image of a predetermined wavelength among the wavelengths imaged in the imaging of the spectroscopic images of each of the wavelengths; and inspecting a color of the inspection object using the spectroscopic images of each of the wavelengths imaged. The predetermined wavelength is determined so that a maximum light quantity of the light from the inspection object in the corresponding spectroscopic image at the predetermined wavelength is equal to or higher than maximum light quantities in the other spectroscopic images at the other wavelengths.

Abstract: A printer moves a color chart relative to a spectrometer that carries out spectral measurement on the color chart. The color chart, which is a color measurement target of the printer, includes a color patch and a white portion that is positioned in a first position and a second position. The first position and the second position interpose a color measurement position, in which the color patch is disposed, along a predetermined direction. The printer acquires measured values by carrying out spectral measurement for the color measurement position, the first position, and the second position, determines a reference value corresponding to the color measurement position based on the measured values of the first position and the second position, and determines a color measurement result of the color patch based on the measured value of the color measurement position and the reference value.

Abstract: A spectrometer includes a spectroscopic measurement section that performs spectroscopic measurement of a target object and that acquires a spectral image, a display section, and a control section that generates Lab visualization information from the spectral image and that causes the display section to display the Lab visualization information. It is desirable that the Lab visualization information is an L-image obtained by converting L-values into luminance for each pixel, an a-image obtained by converting a-values into luminance for each pixel, or a b-image obtained by converting b-values into luminance for each pixel.
