<p>PROBLEM TO BE SOLVED: To provide an image measuring device capable of ensuring satisfactory imaging performance by a small number of illuminating means. SOLUTION: This image measuring device is provided with a two-phase power source for outputting first and second two-phase AC whose phases are shifted by 90 deg., a first AC lighting illuminating means 24 to be driven by the first two-phase AC outputted from the two-phase power source for irradiating a prescribed region, a second AC lighting illuminating means 25 to be driven by the second two-phase AC outputted by the two-phase power source for irradiating the same region as the illuminating region of the first AC lighting illuminating means, an imaging apparatus 27 for imaging an object to be measured existing on the illuminating region to be irradiated by the first and second AC lighting illuminating means 24 and 25, and an image signal correcting means constituted of an image signalγcorrector 28 for correcting an image signal imaged by the imaging apparatus 27.</p> |
