An imaging device is provided with an imaging element. The imaging element has a sensitive wavelength region including an infrared wavelength region, and selectively including a visible wavelength region, and is composed of at least three types of pixels having spectral sensitivities different from each other. The imaging device generates a color image, based on a luminance signal including an infrared wavelength component, and based on a color-difference signal that has been generated based on a visible wavelength component in original image data. The luminance signal including an infrared wavelength component is generated, based on a signal obtained by compressing the dynamic range of original image data including at least three types of original image components acquired by an imaging operation of the imaging element.

To convert a pixel value obtained from a non-reference photoelectric conversion characteristic into a pixel value obtained from a reference photoelectric conversion characteristic without variation, and to prevent generation of fixed pattern noise in an image. An image sensoris constituted of pixels having photoelectric conversion characteristics, in which a linear characteristic is on the low luminance side with respect to an inflection point, and a logarithmic characteristic is on the high luminance side with respect to the inflection point. A conversion information storagestores, as conversion information, coefficients 'c', 'd', &#x201c;e&#x201d;, and &#x201c;f&#x201d; of two kinds of linear functions (y=c&#xb7;log(x)+d, and y=e&#xb7;log(x)+f), which are approximation equations expressing the logarithmic characteristic of each of the pixels, where y designates a pixel value, and x designates a luminance value of incident light. A linear converterconverts a pixel value obtained from the logarithmic characteristic into a pixel value obtained from the linear characteristic by using the approximation equations specified by the coefficients.
