Image processing apparatus, image processing method, and storage medium

An image processing method comprising:

• controlling a reading apparatus to read a document;
• causing a machine learning model to execute a process using a learned parameter and taking a read image of a document as an input, wherein the learned parameter is a model parameter learned with an input image having a color shift and a correct image obtained by reducing a source image having a higher resolution than the input image;
• wherein the color shift results from a shift in reading position between light sources of a plurality of colors;
• and
• obtaining an image output from the machine learning model as a result of executing the process with the read image of the document as an input, the image output from the machine learning model being obtained as an image in which the color shift has been reduced as compared to the read image.

A non-transitory computer readable storage medium storing a program for causing a computer to perform an image processing method, the image processing method comprising:

• controlling a reading apparatus to read a document;
• causing a machine learning model to execute a process using a learned parameter and taking a read image of a document as an input, wherein the learned parameter is a model parameter learned with an input image having a color shift and a correct image obtained by reducing a source image having a higher resolution than the input image;
• wherein the color shift results from a shift in reading position between light sources of a plurality of colors;
• and
• obtaining an image output from the machine learning model as a result of executing the process with the read image of the document as an input, the image output from the machine learning model being obtained as an image in which the color shift has been reduced as compared to the read image.
