Patent application number | Description | Published |
20110176795 | DIGITAL IMAGING METHOD AND APPARATUS - A digital imaging apparatus and method by which an auto-focus (AF) operation may be effectively performed during capture of a moving image. The apparatus performs the AF operation during the capture of the moving image when it is determined that a lens is appropriate for capturing the moving image based on received lens information and stops the AF operation during the capture of the moving image when it is determined that the lens is inappropriate for capturing the moving image. When the lens inappropriate for capturing the moving image is mounted, the AF operation may be performed using an additional switch or a manual-focus (MF) operation may be performed. | 07-21-2011 |
20110221952 | FOCUS ADJUSTMENT APPARATUS AND FOCUS ADJUSTMENT METHOD - Focus adjustment apparatus and methods for effectively auto-focusing on a subject by adaptively changing a shape of a focus area according to a determined image condition, and in particular, setting the focus area in a shape of which a width of an upper part is narrow according to the condition. | 09-15-2011 |
20120062785 | DIGITAL PHOTOGRAPHING APPARATUS AND CONTROL METHOD THEREOF - A digital photographing apparatus includes an AF region setting unit for setting an AF region, a luminance detection area setting unit for setting a luminance detection area, a luminance calculation unit for calculating luminance values of the AF region and the luminance detection area, and a determination unit for calculating a luminance difference value that is a difference value between the luminance value of the AF region and the luminance value of the luminance detection area, and determining validity of an AF evaluation value with respect to the AF region according to the luminance difference value. | 03-15-2012 |
20120062788 | FOCUSING APPARATUS - A focusing apparatus including a focus lens; a focus lens driving unit that drives the focus lens; an imaging device configured to generate an image signal; a focus evaluation value calculating unit configured to receive an image signal from the imaging device and to calculate a focus evaluation value of a captured image; a difference calculating unit configured to calculate a difference between a current focus evaluation value and a previous focus evaluation value; a first determining unit configured to compare the difference to each of a plurality of threshold values different from each other; a counter configured to count results of comparing the difference to each of the plurality of threshold values and to generate count information; and a second determining unit configured to compare the count information to threshold count information and to determine a target drive direction in which the focus lens is to be driven. | 03-15-2012 |
20130300889 | DIGITAL IMAGING METHOD AND APPARATUS - A digital imaging apparatus and method by which an auto-focus (AF) operation may be effectively performed during capture of a moving image. The apparatus performs the AF operation during the capture of the moving image when it is determined that a lens is appropriate for capturing the moving image based on received lens information and stops the AF operation during the capture of the moving image when it is determined that the lens is inappropriate for capturing the moving image. When the lens inappropriate for capturing the moving image is mounted, the AF operation may be performed using an additional switch or a manual-focus (MF) operation may be performed. | 11-14-2013 |
20140184888 | DIGITAL PHOTOGRAPHING APPARATUS AND METHOD OF CONTROLLING THE SAME - A digital photographing apparatus includes a focus lens, a focus detection unit that detects focus in a contrast auto focusing (AF) method by moving the focus lens, and a controller that calculates a velocity of a subject from a first focus detection result and a second focus detection result in a continuous shooting operation. The controller restricts a U-turn driving for correcting backlash of the focus lens when the calculated velocity of the subject is equal to or greater than a predetermined value. An AF initiating location and a final correction operation are adaptively adjusted based on the velocity of the subject in each process of the continuous shooting, thereby improving an AF performance and the continuous photographing speed. | 07-03-2014 |
20140232926 | FOCUS ADJUSTMENT APPARATUS AND FOCUS ADJUSTMENT METHOD - Focus adjustment apparatus and methods for effectively auto-focusing on a subject by adaptively changing a shape of a focus area according to a determined image condition, and in particular, setting the focus area in a shape of which a width of an upper part is narrow according to the condition. | 08-21-2014 |
20150103163 | APPARATUS, METHOD, AND PROCESSOR FOR MEASURING CHANGE IN DISTANCE BETWEEN A CAMERA AND AN OBJECT - Provided is an apparatus for measuring a distance change, the apparatus including an information acquisition unit, an object determination unit, a feature point determination unit, an optical flow calculator, a matching point determination unit, an object length change calculator that calculates a length change ratio between an object of a first frame image and an object of a second frame image by using a feature point and a matching point, and a distance change calculator that calculates a change from a distance between a camera and the object from when the camera acquires the first frame image and when the camera acquires the second frame image using the calculated length change ratio. | 04-16-2015 |
