Patent Images
1. An apparatus to generate an image, the apparatus comprising:
- one of an iris and a shutter or an optical sensor;
an exposure adjustment unit to adjust one of the iris, the iris and the shutter, the shutter or the optical sensor to adjust an exposure amount of a plurality of images;
an image generation unit to generate one of the plurality of images by adjusting an exposure amount based at least in part on a resolution of another of the plurality of images; and
an image synthesis unit to synthesize the generated plurality of images,wherein the image generation unit comprises;
a first image generation unit to generate the first image with a resolution corresponding to a total number of pixels, anda second image generation unit to generate a second image with a lower resolution than that of the first image, by generating the second image corresponding to a combination of a plurality of pixels using identical color filters among the total number of pixels of the first image.

Abstract
An apparatus and method to generate an image in which images having different exposure amounts are generated are provided. The apparatus and method synthesize the generated images and a high-sensitivity (or quality) image can be generated. The apparatus to generate an image includes an exposure adjustment unit to adjust an exposure amount, an image generation unit to generate a plurality of images of different exposure amounts and different resolutions, and an image synthesis unit to synthesize the plurality of generated images.

8. A method of generating an image, the method comprising:
-
generating a plurality of images by adjusting an exposure amount of one of the plurality of images based at least in part on a resolution of another one of the plurality of images; making the resolutions of the generated plurality of images identical; and synthesizing the plurality of images having the identical resolutions, wherein the generating of the plurality of images comprises; generating a first image with a resolution corresponding to the total number of pixels of the first image, and generating a second image with a lower resolution than that of the first image, by combining a plurality of pixels using identical color filters among the total number of pixels of the first image. - View Dependent Claims (9, 10, 11)
