METHOD AND SYSTEM OF GENERATING HIGH DYNAMIC RANGE IMAGE CORRESPONDING TO SPECIFIC SCENE
First Claim
1. A method of generating a high dynamic range (HDR) image corresponding to a specific scene, comprising:
- shooting a specific scene to generate a base image;
selecting a bright area and a dark area from the base image;
determining base luminance according to the base image;
shooting the specific scene to generate at least a first image, wherein average luminance of a part of the first image corresponding to the bright area of the base image is less than or equal to the base luminance;
shooting the specific scene to generate at least a second image, wherein average luminance of a part of the second image corresponding to the dark area of the base image is greater than or equal to the base luminance; and
combining at least the first image and the second image into an HDR image corresponding to the specific scene.

Abstract
A method of generating a high dynamic range image corresponding to a specific scene. The method includes shooting a specific scene to generate a base image; selecting a bright area and a dark area from the base image; determining base luminance according to the base image; shooting the specific scene to generate at least a first image, wherein average luminance of a part of the first image corresponding to the bright area of the base image is less than or equal to the base luminance; shooting the specific scene to generate at least a second image, wherein average luminance of a part of the second image corresponding to the dark area of the base image is greater than or equal to the base luminance; and combining at least the first image and the second image into a high dynamic range image corresponding to the specific scene.

13. A system of generating an HDR image corresponding to a specific scene, comprising:
-
a shooting unit, for shooting a specific scene to generate a base image, at least a first image, and at least a second image; a deciding unit, coupled to the shooting unit, for selecting a bright area and a dark area from the base image, and determining base luminance according to the base image; and a combining unit, coupled to the shooting unit, for combining at least the first image and the second image into an HDR image corresponding to the specific scene; wherein average luminance of a part of the first image corresponding to the bright area of the base image is less than or equal to the base luminance, and average luminance of a part of the second image corresponding to the dark area of the base image is greater than or equal to the base luminance. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
