Color measurement device, image forming apparatus, electronic equipment, color chart, and color measurement method
摘要:
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.
