    Abstract: An imaging apparatus has a color filter array, an image sensor, and a differential information acquisition unit. In the color filter array, including five or more types of color filters are arranged in a two dimensional form. The image sensor has a plurality of pixels covered by the color filters, and the plurality of pixels generate pixel signals. The acquisition unit designates one of the pixels covered by the color filters of interest as a pixel of interest one pixel at a time in order. The acquisition unit calculates first differential information based on pixel signals generated by two of the pixels arranged on both sides of the pixel of interest along the first direction. The acquisition unit calculates second differential information based on pixel signals generated by two of the pixels arranged on both sides of the pixel of interest along the second direction.

    Abstract: The color filter array 21a comprises seven or more types of color filters including a first color filter. The seven or more types color filters have different spectral sensitivity characteristics. The seven or more types of color filters are arranged in a two-dimensional form. Among the seven or more types of color filters, at least two types of color filters are designated as a color filter of interest. Two color filters arranged at a first interval on both sides of the color filter of interest along a first direction are of the same type. Two color filters arranged at a second interval on both sides of the color filter of interest along a second direction that is different from the first direction are of the same type. Among the color filters, at least one type of color filter have a density higher than that of the other types of color filters, thereby realizing acquisition of highly accurate gradient information from a multiband color filter array.
