Abstract
When determining an area in which color blur occurs from an image, there may be an area where color blur suppression is performed in an area even though color blur does not occur, and the area becomes more noticeable or less noticeable depending on a degree of gamma correction processing. To solve this problem, an image processing apparatus obtains a color blur suppression coefficient based on a gradient value obtained from the image, performs color blur suppression on the image data using the color blur suppression coefficient, and changes the color blur suppression coefficient corresponding to the gradient value according to brightness.
