Abstract: The present disclosure provides an evaluation index calculation device, an evaluation index calculation method, and an evaluation index calculation program which are capable of diversifying an evaluation index representing an optical state of a light control sheet. The evaluation index calculation device acquires an evaluation image of an imaging target in a predetermined environment, captured via a light control sheet, and calculates a degree of obscuring caused by the light control sheet in the evaluation image, as an evaluation index, through image analysis of the evaluation image.
