IMAGING DEVICE, COLORIMETRY DEVICE, COLORIMETRY SYSTEM, AND IMAGE FORMATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an imaging device, a colorimetry device, a colorimetry system, and an image formation device, capable of performing stable imaging.SOLUTION: A housing of an imaging part 42 has an opening closed by a mist prevention transmission member. A sensor unit 430 and an illumination light source 426 are provided inside the housing. The housing can move in an optical axis direction of the sensor unit 430 by drive of a carriage lift motor 30. A stained pixel detector 532 detects a stain of the pixel respectively from a first image imaged by the sensor unit 430 when the housing is at a first position and a second image imaged by the sensor unit 430 when the housing is at a second position. In the case that a difference in the number of pixels with detected stains between the first image and the second image is a first threshold or less, a determination part 533 determines that a stain adheres to a light transmission member.
