20140267886 | IMAGE GENERATION SYSTEM, METHOD, AND MEDIUM, GENERATING PLURALITY OF IMAGES WITH DIFFERENT RESOLUTION AND BRIGHTNESS FROM SINGLE IMAGE - Provided is an image generation system and method, more particularly, an image generation system and method which can generate a high dynamic range image from a plurality of images acquired in a single short exposure. The image generation system To includes an image generation system having an image acquisition unit to acquire an image, an image generation unit to generate, from the acquired image, a plurality of images with different resolution and brightness, and an image synthesis unit to synthesize the generated images. | 09-18-2014 |
20140270519 | IMAGE PROCESSING APPARATUS AND METHOD OF PROVIDING HIGH SENSITIVE COLOR IMAGES - An image processing apparatus and method for generating high-sensitive, high-brightness color images are disclosed. A second image having a wider band and higher-sensitivity than those of a first image which includes color information may be acquired, wherein the first and second images are images captured from a scene. A first transformed image having high brightness may be generated by performing binning on the first image, and edge information being a high-frequency component may be extracted from the second image. A high-brightness, high-sensitive color image may be generated using the first transformed image and the edge information. | 09-18-2014 |
20150036927 | APPARATUS AND METHOD OF COMPENSATING CHROMATIC ABERRATION OF IMAGE - The present invention relates to an apparatus and method of correcting a chromatic aberration of an image, and in particular, to an apparatus and method of correcting a chromatic aberration of an image that can correct a general chromatic aberration of an edge or an extreme chromatic aberration, such as a purple fringe, in an image. An apparatus for correcting a chromatic aberration of an image according to an embodiment of the present invention includes an edge detection unit detecting an edge of an input image, a level calculation unit calculating a chromatic aberration level of the detected edge, and a correction unit correcting the edge using different weighted values according to the calculated chromatic aberration level. | 02-05-2015 |
