Abstract
An image processing apparatus obtains distance information indicating a distance to each of one or more objects of an image, performs grouping of the one or more objects in accordance with the distance to each object, extracts a plurality of object regions of the image in accordance with the grouping, and determines, in accordance with a number of the plurality of object regions extracted by the extraction unit, whether to perform tone conversion by applying a same tone characteristic to the image as a whole or to perform tone conversion by applying different tone characteristics for respective regions of the image.
Claims12
An image processing apparatus comprising:
- at least one processor or circuit configured to function as:
- an obtaining unit configured to obtain distance information indicating a distance to each of one or more objects of an image;
- an extraction unit configured to perform grouping of the one or more objects in accordance with the distance to each object and to extract a plurality of object regions of the image in accordance with the grouping;
- a determination unit configured to determine, in accordance with a number of the plurality of object regions extracted by the extraction unit, whether to perform tone conversion by applying a same tone characteristic to the image as a whole or to perform tone conversion by applying different tone characteristics for respective regions of the image;
- a setting unit configured to set a tone characteristic;
- and
- a conversion unit configured to perform tone conversion on the image in accordance with a determination result of the determination unit.
