1. An information processing apparatus, comprising:
a processing circuit configured to:
generate a synthesized noise image based on an input original image; and
process a black level in the synthesized noise image, and train a machine learning model for image denoising based on the processed synthesized noise image to obtain a trained machine learning model,
wherein the processing circuit is further configured to:
acquire predetermined image acquisition parameters from the original image,
obtain a corresponding offset image based on correspondence relationship between the predetermined image acquisition parameters and offset images for processing the black level, and
process the black level in the synthesized noise image based on the obtained offset image.
