Data processing apparatus, method, program, and multispectral camera

A data processing apparatus comprising:

• a processor configured to process first captured data that corresponds to a plurality of wavelength ranges output from an image sensor of a multispectral camera having an opening region allowing transmission of light of different transmission wavelength ranges at a pupil position or near the pupil position and that includes first noise,
• wherein the processor is configured to:
• acquire an interference removing parameter for removing an interference component included in the first captured data;
• perform interference removing processing of removing the interference component included in the first captured data based on the interference removing parameter to generate second captured data;
• and
• perform noise reducing processing of reducing second noise included in the second captured data
• acquire noise characteristic data indicating a noise characteristic of the first captured data;
• acquire a first noise amount parameter based on a signal value of a pixel of the first captured data and on the noise characteristic data;
• and
• acquire a second noise amount parameter based on the acquired first noise amount parameter and on the interference removing parameter.
