Document Type and Number:
Japanese Patent JP2015080051
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve such a problem that one patch size is reduced when a number of patches required for calibration are arranged, and the operability degrades, in a color chart where a color patch for use in color calibration is arranged.SOLUTION: In a test chart for color calibration, patches are arranged in a grid. In the scanning direction of a colorimetry device, slits are provided between the patches. Furthermore, guides (1202, 1203) indicating the width of the colorimetry device, when scanning the patch line, are arranged in the slit. Preferably, each patch line is composed of patches of one color component of different density, and a guide for scanning the line is composed of the same color as that of the patch line.
