Abstract: An image processing apparatus includes: a processor configured to execute: acquiring image data; generating a first interpolation image data corresponding to light in a red wavelength band, a second interpolation image data corresponding to light in a green wavelength band, a third interpolation image data corresponding to light in a blue wavelength band, and fourth interpolation image data corresponding to narrow band light; calculating a ratio of a pixel value of the fourth interpolation image data to a pixel value of the second interpolation image data for each region including one or a plurality of pixels; extracting a pixel of the fourth interpolation image data in the region where the calculated ratio exceeds a predetermined threshold value; generating a composite image data based on the pixel value of the extracted pixel and the second or the third interpolation image data; and generating color image data.

Abstract: A multi-area white-balance control device includes a device that divides an inputted image into a plurality of areas, a device that estimates a white-balance correction gain for each of the divided areas, a device that determines whether the estimated white-balance correction gain of the area is peculiar or not, based on comparison with estimated white-balance correction gains of adjacent areas of the area and a device that modifies an estimated white-balance correction gain of an area determined to be peculiar, based on estimated white-balance correction gains of adjacent areas; and realizes color reproduction without unnaturalness even if white-balance correction gain estimation is wrong in an individual area.

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.
