Assignee: CANON KABUSHIKI KAISHA
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 15:
16. An information processing method of generating learning data for demosaic processing by machine learning, the method comprising the steps of:
acquiring a first image; and
generating, based on the first image, a data set including a set of a second image and a third image;
wherein
the second image is the first image to which noise is added and
the third image is a mosaic image obtained by thinning predetermined pixels from the first image by mosaic processing to which noise is added, and it is used for the machine learning as a pair of the second image,

wherein at least one of one or more circuits or execution of instructions cause an information processing apparatus to cause a generation unit to additionally function as:
a separation unit configured to separate the first image into channel images corresponding to each channel of RGB;
an addition unit configured to add noise to each of a channel image;
a mosaic image generation unit configured to generate a mosaic image to which noise is added by sampling, in accordance with a color filter array, predetermined pixels in each channel image to which the noise is added by the addition unit;
a connection unit configured to generate an image including three channels of RGB to which noise is added by connecting each channel image to which the noise is added by the addition unit; and
an image pair generation unit configured to obtain the data set by taking a demosaic image to which the noise is added as the third image and the image including three channels of RGB to which the noise is added as the second image.
