Abstract: A document evaluation apparatus includes: a document data acquisition unit that acquires document data including at least text objects; a preliminary processing unit that performs a preliminary process on the document data acquired by the document data acquisition unit; an information volume evaluation unit that evaluates an amount of information in the document data based on the preliminarily processed document data; a character evaluation unit that evaluates the legibility of text based on the preliminarily processed document data; and a color evaluation unit that evaluates the relationships among adjacent colors in the document data based on the preliminarily processed document data.

Abstract: An information processing apparatus includes: a determiner configured to determine whether a combination of adjacent two colors in inputted image data is a combination in which a person with color blindness is likely to confuse the two colors; and a decider configured to decide, as a proposed change of the combination of the two colors, for the combination determined to be the combination in which the person with color blindness is likely to confuse the two colors by the determiner, a combination in which at least one of the two colors is changed such that the person with color blindness is capable of distinguishing the two colors and in which a degree of change of the at least one changed color of the two colors is minimized for a person with normal color vision.
