ILLUMINATION EVALUATION DEVICE AND ILLUMINATION EVALUATION METHOD

摘要

An illumination evaluation apparatus evaluates an illumination environment by an arbitrary light source and includes: a visual target presenting unit which presents a visual target 13 at an arbitrary test position on an irradiation area 12 irradiated by illumination light emitted from the light source, the visual target being provided for acquiring contrast sensitivity of an observer looking at the irradiation area 12; and a recording unit which acquires a value of the contrast sensitivity when the observer looks at the visual target 13 presented by the visual target presenting unit and records the acquired value of the contrast sensitivity and positional information at the test position. The illumination evaluation apparatus evaluates visibility at the arbitrary position on the irradiation area 12 by the acquired value of the contrast sensitivity.
