Data processing apparatus, data processing method, and program

A data processing method comprising:

• performing interpolation to generate calibration data for a predetermined focus position by using calibration data for a plurality of focus positions, the calibration data for the plurality of focus positions being generated from a calibration image captured at the plurality of focus positions, the calibration image being obtained by capturing an image of a known object in the plurality of focus positions with a multi-lens camera that captures an image from two or more viewpoints.

A program causing a computer to function as:

• an interpolation section that performs interpolation to generate calibration data for a predetermined focus position by using calibration data for a plurality of focus positions, the calibration data for the plurality of focus positions being generated from a calibration image captured at the plurality of focus positions, the calibration image being obtained by capturing an image of a known object in the plurality of focus positions with a multi-lens camera that captures an image from two or more viewpoints.
