Imaging device, imaging method, and image processing program

An imaging method in an imaging device including a multiple-property lens that includes a first area having a first property and a second area having a second property different from the first property, and an image sensor that has a first light receiving element and a second light receiving element having a different opening size of a light receiving section from the first light receiving element, the first light receiving element on which a luminous flux passing the first area of the multiple-property lens and a luminous flux passing the second area of the multiple-property lens are incident in crosstalk with each other and the second light receiving element having a different crosstalk ratio due to having the different opening size from the first light receiving element and on which the luminous flux passing the first area of the multiple-property lens and the luminous flux passing the second area of the multiple-property lens are incident in crosstalk with each other being two-dimensionally arranged, the method comprising:

• a step of acquiring a first crosstalk image and a second crosstalk image that are imaged by the imaging device at the same time, the first crosstalk image being photoelectrically converted by the first light receiving element of the image sensor, and the second crosstalk image being photoelectrically converted by the second light receiving element;
• and
• a step of generating a first image and a second image respectively having the first property and the second property of the multiple-property lens by removing a crosstalk component from each of the first crosstalk image and the second crosstalk image acquired.

• a step of acquiring a first crosstalk image and a second crosstalk image that are imaged by the imaging device at the same time, the first crosstalk image being photoelectrically converted by the first light receiving element of the image sensor, and the second crosstalk image being photoelectrically converted by the second light receiving element;
• and
• a step of generating a first image and a second image respectively having the first property and the second property of the multiple-property lens by removing a crosstalk component from each of the first crosstalk image and the second crosstalk image acquired.
