Image Generation Device, Image Generation Method, and Program
7 Sep 23
This image generation device comprises an image generation unit for using an image generation algorithm (AR)—which has been trained on the basis of defect images (PD) that are inspection images showing defects (D) and label images (PL) obtained by adding, to the defect images, labels (Lr) corresponding to the types and shapes of the defects-to input a label image for image generation that has been created through the addition of a desired label to a background image and generate a pseudo-defect image by drawing, on the background image, a pseudo defect corresponding to the label added to the label image for image generation.
