| 20110019014 | APPARATUS AND METHOD FOR OBTAINING MOTION ADAPTIVE HIGH DYNAMIC RANGE IMAGE - Disclosed is an apparatus and method for obtaining a motion adaptive high dynamic range image, in which a motion degree of a first image and a second taken using different exposure times is calculated. The motion calculation intensity is adjusted based on the calculated motion degree. The motion compensation intensity involves a global motion compensation and/or a location motion compensation. Images subjected to compensation are synthesized and output, so that an image having high dynamic range is obtained. | 01-27-2011 |
| 20110069200 | HIGH DYNAMIC RANGE IMAGE GENERATING APPARATUS AND METHOD - A high dynamic range (HDR) image generating apparatus and method is provided. The HDR image generating apparatus may set an auto-exposure time, a long exposure time, a short exposure time, and a reference exposure time. The auto-exposure time may be set to be shorter than the long exposure time, the short exposure time may be set to be shorter than the auto-exposure time, and the reference exposure time may be set to fall within a range between the auto-exposure time and the short exposure time. The image generating apparatus may obtain a first image with the long exposure time and a second image with the reference exposure time, may correct motion in the first image and adjust a dynamic range of the second image, and then may composite the resultant first and second images to generate a high dynamic range image. | 03-24-2011 |
| 20110069906 | METHOD AND APPARATUS FOR BLENDING IMAGES - A method and apparatus may include aligning a reference image and an input image through ROI-based image alignment; detecting an ROI associated with an incompletely aligned region in the aligned image; and blending the aligned reference image and input image by using a plurality of weights which are attenuated according to a spatial distance from a boundary of the detected ROI. In addition, the method and apparatus may include aligning a reference image and an input image through image alignment based on an n | 03-24-2011 |

| 20080253676 | Apparatus and method for removing motion blur of image - An apparatus for removing motion blur of an image is disclosed. The apparatus includes a motion-blur-function-estimation unit that estimates the motion-blur function of an input image, an image-restoration unit that restores the input image using the estimated motion-blur function, a cost-calculation unit that calculates the blur cost of the restored image, and a control unit that determines the re-estimation of the motion-blur function depending on the calculated blur cost. | 10-16-2008 |
| 20090180704 | Method and system for processing low-illuminance image - Provided are a method and system for processing a low-illuminance image. The system includes an image acquisition unit to acquire two images having different levels of illuminance and sensitivity as first and second images; a motion vector estimation unit to extract a motion vector of the second image based on the first image; an image correction unit to correct the second image using the extracted motion vector; a synthesis coefficient calculation unit to calculate a synthesis coefficient used to synthesize the first image and the corrected second image; and an image synthesis unit to synthesize the first image and the corrected second image using the calculated synthesis coefficient. | 07-16-2009 |
| 20090185041 | Apparatus and method of obtaining image and apparatus and method of processing image - Provided are an apparatus and method of obtaining a high-quality image by efficiently processing an image obtained at low-light levels. The image obtaining apparatus comprises a sensor which detects a pixel array value by using a color filter including color pixels for obtaining a color image and a reference pixel for obtaining a reference image used for hand-trembling function estimation; an exposure controller which controls exposure times of the color pixels and the reference pixel; and an image generator which generates a long-exposure color image signal and a short-exposure reference image signal from the detected pixel array value, the long-exposure color image signal and the short-exposure reference image signal being aligned with each other. Accordingly, accurate estimation of the hand-trembling function is possible, thereby enabling the high-quality color image restoration. | 07-23-2009 |
| 20100084556 | OPTICAL-INFRARED COMPOSITE SENSOR AND METHOD OF FABRICATING THE SAME - Provided are an optical-infrared composite sensor and a method of fabricating the same. The optical-infrared composite sensor can sense both optical and infrared radiation. The optical-infrared composite sensor includes an infrared sensor formed on a substrate, a silicon cap enveloping the infrared sensor to vacuum-package the infrared sensor, and an optical sensor formed at one side of the silicon cap. | 04-08-2010 |
| 20100085453 | APPARATUS FOR OPTICALLY COMBINING VISIBLE IMAGES WITH FAR-INFRARED IMAGES - An image sensing apparatus, particularly, an apparatus for optically combining visible images with far-infrared images is provided in which performing a separate signal processing may not be needed. The image combining apparatus emits light that is sensed by an image sensor, and reflects the light toward the image sensor in response to far-infrared rays being sensed from an object, thereby converting far-infrared information into information that can be sensed by the image sensor. | 04-08-2010 |
