PROBLEM TO BE SOLVED: To provide an imaging unit capable of performing stable imaging, a colorimetric device, an image forming apparatus, a colorimetric system, and a colorimetric method.SOLUTION: An imaging unit 42 of an embodiment includes a sensor unit 430 that photographs a predetermined area (imaging area) including a subject such as a patch image 200, and a reference chart unit 400 that is arranged in the imaging area and is photographed by the sensor unit 430 together with the subject such as the patch image 200.
Abstract:
A system includes a plurality of scanning devices and light receivers, enabling a plurality of images of a site to be displayed using output signals produced in response to light from the light receivers. To avoid crosstalk caused by light receivers receiving light emitted by a plurality of scanning devices, different wavebands of light can be applied to different scanning devices, the received light can be filtered, or the light can be supplied to one scanning device at a time to multiplex either frame-by-frame, or pixel-by-pixel, or the light supplied to each scanning device can be modulated and the received light demodulated so that an image is produced in response to light from a single scanning device. Expensive components such as laser light sources, optical detectors, a controller, and processor can be shared by multiple imaging devices to minimize the cost of the imaging system.
Abstract:
