IMAGING DEVICE AND IMAGE READER

摘要

PROBLEM TO BE SOLVED: To provide an imaging device imaging an object with the most suitable dynamic range irrelevantly to the dynamic range of an imaging element, and an image reader. SOLUTION: The imaging device comprises the imaging element having a linear pre-imaging pixel array and an actual imaging pixel array and a lighting means of lighting up the subject, and can image the subject with the most suitable dynamic range irrelevantly to the dynamic range of the imaging element by controlling the quantity of illumination light of the lighting means by using a pre-imaging output of the pre-imaging pixel array; and the image reader.
