The histogram creation module is configured to create a histogram of luminance values in an input image. The parameter creation module is configured to create a parameter indicating an input-output characteristic to correct the input image by equalizing the histogram. Where the histogram creation module is configured to determine whether a target pixel in the input image is a local low-luminance pixel or not, and omit to count a frequency of a luminance value of the target pixel if the target pixel is determined to be the local low-luminance pixel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image correction apparatus and correction parameter creation apparatus","description":"According to one embodiment, a correction parameter creation apparatus includes a histogram creation module and a parameter creation module.
