7. A mask structure optimization method comprising:
a classification target image size acquiring step of acquiring a size of a classification target image which is an image including a classification target;
a mask size setting step of setting a size of a mask applied to the classification target image;
an initial value setting step of setting an initial value for a mask pattern of the mask;
a convolutional processing step of executing convolutional processing for the classification target image and an image of the mask; and
a mask pattern optimizing step of optimizing the mask pattern of the mask on the basis of results of the convolutional processing executed in the convolutional processing step,
wherein the mask is an optical mask having a plurality of regions with different optical characteristics.
