1. An information processing apparatus, comprising:
processing circuitry configured to:
generate a converted image by performing an image conversion on raw data obtained by imaging a subject with a medical scanning apparatus or an inspection apparatus,
calculate a plurality of bases by performing a basis conversion on the converted image as signal data;
select one or more specific bases with contribution rates lower than a reference from among the calculated plurality of bases;
generate, from the raw data, an output image that satisfies a constraint condition relating to projection amounts to the one or more specific bases; and
output the generated output image.
