Claim One:
1. An imaging apparatus comprising: an image sensor device; and a processor comprising hardware, wherein the processor is configured to: receive a spectral characteristic of a subject, wherein the spectral characteristic is measured by a spectroscopic sensor device; determine at least one color separation within the spectral characteristic of the subject; determine a spectral wavelength band for each of the at least one color separation; control a transmittance characteristic setting of the image sensor device based on the spectral wavelength band; and control the image sensor device to capture a spectral image of the subject at the transmittance character setting, wherein the image sensor device comprises: an image sensor configured to capture the spectral image by photoelectrically converting a subject image formed by at least one image forming optical lens to create an image signal, and a filter having a variable transmittance characteristic and provided in an optical path of the at least one image forming optical lens to change a spectral characteristic of the subject light incident onto the image sensor, and wherein the processor is configured to control the transmittance characteristic setting of the image sensor device by controlling the variable transmittance characteristic of the filter, based on the spectral wavelength band.
