Abstract: An image processing device includes: a separation unit configured to separate a plurality of wide-band image signals corresponding to wide-band light passing through each of a plurality of wide-band filters and a narrow-band image signal corresponding to narrow-band light passing through a narrow-band filter, from each other, based on an image signal input from an imaging device; a demosaicing unit configured to perform demosaic processing that interpolates one of the plurality of wide-band image signals based on edge information from the narrow-band image signal separated by the separation unit; and an image generation unit configured to generate a wide-band image by using the wide-band image signal interpolated by the demosaic processing performed by the demosaicing unit and generate a narrow-band image by using the narrow-band image signal.

Abstract: An imaging system includes: an imaging sensor; a plurality of first band filters and a second band filter, the second band filter being configured to transmit narrowband light having a maximum value of a transmission spectrum outside a range of a wavelength band of light that passes through the first band filter; and a light source unit configured to radiate light having a projecting distribution in which at least one of an upper limit value and a lower limit value of a wavelength that are half a maximum value in a light spectrum of a light source is between an upper limit value and a lower limit value of a wavelength that are half the maximum value in the transmission spectrum of the second band filter. A color and a narrowband images are generated from a single image while the light source unit radiates the light.

Abstract: An imaging device includes: an imaging sensor; a color filter including first band filters and a second band filter configured to transmit narrowband light having a maximum value of a transmission spectrum outside a range of the wavelength band of the light that passes through each first band filter; a first light source unit; a second light source unit configured to radiate light having an upward projecting distribution of a wavelength spectrum in relation to intensity and having a narrowband light spectrum narrower than the broadband; and a control unit configured to cause the first light source unit and the second light source unit to radiate the beams of light simultaneously, wherein a peak wavelength of the light radiated by the second light source unit is an infrared region or a near-infrared region.

Abstract: An imaging device includes an image sensor. The image sensor includes: a light receiving unit having pixels configured to receive light and generate an imaging signal according to an amount of the received light; a color filter having a filter unit disposed corresponding to the pixels, the filter unit including first band filters for passing light of a wavelength band of a primary color or a complementary color and including at least one second band filter for passing narrow-band light whose wavelength band is narrower than the wavelength band of the light passing through each of the first band filters; and an output unit configured to output the imaging signal under conditions that an amount of light incident on a second pixel corresponding to the at least one second band filter is greater than an amount of light incident on each of first pixels corresponding to the first band filters.
