Image processing apparatus, image processing method, and program

摘要

A method for processing an image includes acquiring a low frequency component of a luminance component of an image, correcting the luminance component of the image using the acquired low frequency component, determining a level correction amount of each pixel of the corrected image using a frequency distribution of low frequency components of the acquired image and a low frequency component of each pixel of the image, and performing level correction using the determined level correction amount and a luminance distribution of the corrected image.

主权项

1. An apparatus comprising at least one processor which functions as:
an acquisition unit configured to acquire a low frequency component of a luminance component of an image; a correction unit configured to correct a luminance component of the image using the acquired low frequency component; a determination unit configured to determine a level correction amount of pixels of the corrected image using a value obtained from a frequency distribution of the image corrected by the correction unit and a luminance component of pixels of the image corrected by the correction unit; and a level correction unit configured to perform level correction on the corrected image using the determined level correction amount.
