摘要： An image inspecting apparatus includes a first light illuminating unit that irradiates a measured object on which an image is formed with illuminating light from a diagonal direction; an imaging unit that receives specular light of the illuminating light with which the measured object is irradiated by the first light illuminating unit; and an image inspecting unit that inspects the image. The image inspecting unit generates gloss reference data from density distribution data included in print data used for forming the image by using a converting unit. The image inspecting unit inspects a gloss distribution of the image by using the gloss reference data and a gloss distribution of the image that is generated based on an amount of the specular light received by the imaging unit.

摘要： An image inspection device includes a first illuminating unit illuminating an object from an oblique direction with a first illuminating light; an imaging unit receiving specular reflection light of the first illuminating light from the object; and a focusing unit focusing the specular reflection light on the imaging unit. The image inspection device is configured to inspect the image based on the intensity of the specular reflection light received by the imaging unit. The first illuminating unit includes light-emitting elements and an illumination light producing unit that is configured to deflect light emitted from the light-emitting elements and thereby to produce the first illuminating light such that the specular reflection light from the object enters a pupil of the focusing unit.
