Abstract
The present disclosure relates to an image processing apparatus, an image processing method, and a program which highlight a main object more outstandingly. A tone curve adjustment unit performs tone curve adjustment on a target region of an input image signal (IN), and supplies an image signal subjected to the tone curve adjustment to a local level detection unit. The local level detection unit obtains a local level. A contrast adjustment unit performs adaptive contrast enhancement according to the local level from the local level detection unit. The present disclosure can be applied to an image processing apparatus which highlights a predetermined part of an image using the tone curve adjustment and the adaptive contrast adjustment, for example.
Claims20
An image processing apparatus comprising:
- a tone curve adjustment unit to perform tone curve adjustment on at least one of a main object region and an other region, which is a region other than the main object region, in an image;
- and
- a contrast adjustment unit to perform contrast enhancement on a region where the tone curve adjustment has been performed by the tone curve adjustment unit.
An image processing method comprising:
- performing, by an image processing apparatus, tone curve adjustment on at least one of a main object region and an other region, which is a region other than the main object region, in an image;
- and
- performing, by the image processing apparatus, contrast enhancement on a region where the tone curve adjustment has been performed.
A program causing a computer to function as:
- a tone curve adjustment unit to perform tone curve adjustment on at least one of a main object region and an other region, which is a region other than the main object region, in an image;
- and
- a contrast adjustment unit to perform contrast enhancement on a region where the tone curve adjustment has been performed by the tone curve adjustment unit.
