Patent ID: 7505622

Claim:
A color information acquisition apparatus that measures a color chart consisting of a plurality of patches and acquires the color values of the patches, said color information acquisition apparatus comprising: an input section that inputs color values of patches composing one line in the color chart by measuring one line in the color chart; a measured line identification processor that identifies which line of lines composing the color chart is a measured line based on the color values input by the input section, and determines whether an identified line matches an expected line that is expected to be measured in order of measurement predetermined for each line of the color chart; a warning section that performs a predetermined warning processing if the identified line and the expected line do not match; and a color value saving section that, when a line correction instruction that instructs to correct the expected line is input, saves the color value of each patch input by the input section by making the color value of each patch that the input section input correspond to gradation value of each patch composing the identified line.
