Abstract
An image processing apparatus useable for correcting an image includes an input unit to receive an input of an image; an area dividing unit to divide the image, input to the input unit, into a plurality of areas having different lighting conditions; a computing unit to compute a correction coefficient for each of the divided areas divided by the area dividing unit; a movement detector to detect a movement between the first image and the second image supplied from the input unit along the time line; a boundary determination unit to determine a boundary between the areas to which correction coefficients of each of the areas are blended based on the movement detected by the movement detector; and a setting unit to set image correction coefficient data for the image input to the input unit based on the boundary between the areas determined by the boundary determination unit.
