Imaging apparatus, imaging method, and imaging program

The deterioration of image quality due to the mixture of light during pixel mixture is prevented. A filter that transmits a green light component is formed on a light receiving surface of a photoelectric conversion element and a filter that transmits a red light component is formed on a light receiving surface of a photoelectric conversion element. Light which is vertically incident on the filter is incident on the corresponding photoelectric conversion element. However, light which is obliquely incident on the filter is mixed with a photoelectric conversion element adjacent to the corresponding photoelectric conversion element. When pixel mixture is performed, mixed pixel data is reduced from the data of a mixed pixel to perform mixture correction.
