Abstract:
1. An apparatus for acquiring colorimetric values of color patches in a color chart, which comprises color patches of a multi-row, by using a colorimeter which is manually slid by a user to perform colorimetry while scanning the plural color patches in the color chart on a row-by-row basis, the apparatus comprising: an obtaining unit configured to obtain a first feature value of color patches for each row in the color chart, comprising the color patches of the multi-row having a color-difference for each row, relating to color arrangement of color patches in a predetermined scanning direction by the colorimeter, a specifying unit configured to specify a feature value of a color patch for each row relating to the color arrangement in each measured row as a second feature value on a basis of the colorimetric values of the color patches acquired by the colorimeter which is manually slid by a user to perform colorimetry, and a determining unit configured to determine whether a scanning direction, in which the colorimetry has been performed by using a colorimeter which is manually slid by a user, is the predetermined scanning direction based on the second feature value for each row specified by the specifying unit and the first feature value obtained by the obtaining unit corresponding to the each row.
