Abstract
An imaging device includes an imaging element including first pixels, each outputs a signal including color information, and second pixels having higher sensitivity than the first pixels, and a signal processing unit including a luminance value acquisition unit that acquires luminance values in the first pixels based on signals from the second pixels and a color acquisition unit that acquires color ratios by using color and luminance values in the first pixels. When a color value in the first pixels corresponding to one color is larger than a luminance value, the color acquisition unit corrects the luminance value in the first pixels corresponding to the one color so that a ratio of the color value and the luminance value in the first pixels corresponding to the one color is closer to a ratio of a color value and a luminance value in the first pixels corresponding to another color.
