Abstract
Provided are an image processing method, a digital image processing apparatus, and a recording medium storing the image processing method. The method includes capturing a first image, a second image, and a third image, which are captured with different focuses for the same subject and background; setting a subject portion and a background portion by using the first and second images; and combining the first image for the subject portion and the third image for the background portion with each other to obtain an out-of-focus image.
Claims24
A digital image processing apparatus comprising:
- a storage unit in which reference subject distance information used to perform out-of-focus image processing according to reference zoom information is stored;
- a zoom information obtaining unit configured to obtain zoom information;
- a reference subject distance information obtaining unit configured to obtain the reference subject distance information corresponding to the zoom information from the storage unit;
- a notification unit configured to output notification information corresponding to the reference subject distance information;
- an image generating unit configured to generate a first image in which a subject is focused, a second image in which a background is focused, and a third image that is not focused;
- a setting unit configured to set a subject region and a background region of each of the first image and the second image;
- and
- an out-of-focus image generating unit configured to generate an out-of-focus image by combining the subject region of the first image with the background region of the third image.
A digital image processing method comprising:
- obtaining zoom information;
- obtaining reference subject distance information corresponding to the zoom information obtained from a database of reference subject distance information used to perform out-of-focus image processing according to reference zoom information;
- outputting notification information corresponding to the reference subject distance information;
- generating a first image in which a subject is focused, a second image in which a background is focused, and a third image that is not focused;
- setting a subject region and a background region of each of the first image and the second image;
- and
- generating an out-of-focus image by combining the subject region of the first image with the background region of the third image.
A non-transitory computer program product, comprising a computer usable medium having a computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method, said method comprising:
- obtaining zoom information;
- obtaining reference subject distance information corresponding to the zoom information obtained from a database of reference subject distance information used to perform out-of-focus image processing according to reference zoom information;
- outputting notification information corresponding to the reference subject distance information;
- generating a first image in which a subject is focused, a second image in which a background is focused, and a third image that is not focused;
- setting a subject region and a background region of each of the first image and the second image;
- and
- generating an out-of-focus image by combining the subject region with the first image and combining the background region with the third image.
A digital image processing apparatus comprising:
- an image generating unit configured to generate a first image in which a subject is focused, and a second image in which a background is focused;
- a setting unit configured to set a subject region and a background region of each of the first image and the second image;
- and
- an out-of-focus image generating unit configured to generate an out-of-focus image by combining the subject region of the first image with the background region of the third image.
