A local contrast correction unit multiplies a signal of a target pixel in image data by a gain based on values obtained by reflecting signals of pixels around the target pixels. For signals of the target pixel output from the local contrast correction unit, a gamma conversion unit performs gamma conversion based on the signal of the target pixel. An edge signal is extracted from the image data and multiplied by a gain based on a signal output from the local contrast correction unit. The edge signal is added to a signal output from the gamma conversion unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing apparatus that performs tone correction and edge enhancement, control method therefor, and storage medium","description":"An image processing apparatus which enables natural edge enchantment suited to a frequency band of a subject even when performing local contrast correction in combination with edge enhancement.
