Abstract

An image processing apparatus comprises a changing unit configured to change a display area of an image from a first display area to a second display area including at least a portion of the first display area, an acquiring unit configured to acquire a first value indicating luminance, in which brightness contrast is considered, in an image displayed in the first display area and a second value indicating luminance, in which brightness contrast is considered, in an image displayed in the second display area, and a correcting unit configured to correct luminance of the image displayed in the second display area based on the first value and the second value that are acquired by the acquiring unit.

Dependent claims

An image processing apparatus comprising:

at least one processor or circuit configured to function as:
a changing unit configured to change a displayed image from a first image to a second image, wherein the first image includes a first area and a second area of a captured image obtained by image capturing and the second image includes the first area of the captured image but does not include the second area of the captured image;
an acquiring unit configured to acquire a first value indicating luminance, in which influence of brightness contrast is considered, in the first image and a second value indicating luminance, in which influence of brightness contrast is considered, in the second image, wherein the influence of the brightness contrast corresponds to a perceived amount of brightness of an object region based on brightness of a surrounding region of the object region in the first image and the second image;
and
a correcting unit configured to correct luminance of the second image based on the first value and the second value that are acquired by the acquiring unit.
