The image processing apparatus includes a grid pattern removal unit, a filtering unit, and a distortion correction unit. The grid pattern removal unit is configured to generate a grid pattern removal image by removing a grid pattern from the radiation image. The filtering unit is configured to extract a frequency component lower than a frequency of the grid pattern from the radiation image. The distortion correction unit is configured to replace a low-frequency component included in the grid pattern removal image with a frequency component obtained by the filtering unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing apparatus, image processing method, and storage medium","description":"An image processing apparatus removes a pattern caused by a grid from a radiation image captured by using a scattered ray removal grid.
