20090015921 | METHOD AND APPARATUS FOR COMPENSATING HAND-TREMBLING OF CAMERA - A method and apparatus for compensating hand-trembling of a camera with reduced time required for capture compensated images. The method may include: calculating exposure time proper for preventing hand-trembling using an AE (Automatic Exposure) algorithm during an image-capturing standby mode; executing image-capturing multiple times depending on the exposure time at the time of inputting a photographing signal through a photographing button, and detecting the amount of hand-trembling at each time of image-capturing. The storing of images can be selected by a preset number of required images from the captured images as resultant images, the images being sequentially stored from an image having a lowest amount of hand-trembling as a resultant image, whereby an image with reduced hand-trembling can be obtained. | 01-15-2009 |
20090102837 | 3D GRAPHIC RENDERING APPARATUS AND METHOD - A three-dimensional (3D) graphic rendering apparatus is provided. The 3D graphic rendering apparatus includes an object-information extraction module which extracts a bound box of each of a plurality of objects, including an i-th object and a j-th object, wherein i and j are natural numbers; an object alignment module which aligns the i-th object and the j-th object according to distances of the i-th and j-th objects, based on the extracted bound boxes of the i-th and j-th objects, from a visual point; and a rendering module which sequentially renders the aligned i-th and j-th objects such that an object among the i-th and j-th objects distant from the visual point can be rendered earlier than an object among the i-th and j-th objects less distant from the visual point. | 04-23-2009 |
20090143099 | MOBILE COMMUNICATION TERMINAL HAVING CONVERSION LENS AND PHOTOGRAPHY METHOD USING THE SAME - Provided are a mobile communication terminal and a photography method for the same using a conversion lens. The mobile communication terminal includes a terminal body, a camera assembly installed at one side of the terminal body and a conversion lens detachably installed on a front surface of the camera assembly, wherein product data of the conversion lens mounted on the camera assembly are automatically identified and a microcomputer installed in the terminal body automatically adjusts a photography mode such that a special photography mode is entered without requiring any professional knowledge. | 06-04-2009 |
20090147141 | METHOD AND APPARATUS FOR VIDEO TELEPHONY IN MOBILE TERMINAL - A method and apparatus for video telephony in a mobile terminal includes: extracting, after establishment of a video call, a facial feature from a video image captured by a camera unit of the mobile terminal, comparing the extracted facial feature with that of a pre-stored reference image, and correcting the video image according to the facial feature of the reference image. The corrected video image is transmitted to a counterpart of the video call. | 06-11-2009 |
20100321770 | HYBRID IR CUT-OFF FILTER FOR DIGITAL CAMERA - Disclosed is a hybrid Infrared Ray (IR) cut-off filter for a digital camera, which includes an absorption filter plate for absorbing infrared rays, a reflection coating layer formed on a top or bottom side of the absorption filter plate so as to reflect infrared rays, and an anti-reflection coating layer formed on the top or bottom side of the absorption filter plate opposite the reflection coating layer, so as to allow visible rays to pass through the anti-reflection coating layer. The hybrid IR cut-off filter can provide an excellent IR cut-off function even in a slim digital camera module. Also, the hybrid IR cut-off filter can prevent the image quality from being degraded due to the IR transmittance difference according to the change in the incidence angle of an incident light, thereby overcoming the problem of color difference according to the color temperature. | 12-23-2010 |
20110170846 | METHOD AND APPARATUS FOR AUTO-FOCUS CONTROL OF DIGITAL CAMERA - Disclosed is a method for auto-focus control of a digital camera, the method including moving a focus lens of the digital camera to a position for a longest-distance photographing, and then extracting an edge value according to a corresponding position while moving the focus lens by a preset interval in a direction toward an image sensor; estimating a form of a preset function based on the extracted edge values, and calculating a maximum value of the estimated function; calculating a difference between a maximum value of the preset function calculated at a first current position of the focus lens and a maximum value of the preset function calculated at a previous position of the focus lens; and moving the focus lens to a position corresponding to a currently-calculated maximum value of the preset function when the difference between the maximum value of the preset function calculated at the first current position of the focus lens and the maximum value of the preset function calculated at the previous position of the focus lens is less than or equal to a preset threshold value. | 07-14-2011 |
20130194246 | DISPLAY APPARATUS, UPGRADE APPARATUS, CONTROL METHOD THEREOF, AND DISPLAY SYSTEM - Embodiments disclose a display apparatus including: an image processing device which processes an image signal; a display device which displays an image based on the processed image signal; a connection device which connects to an upgrade apparatus which processes the image signal; a power supply device which supplies power to each component of the display apparatus and the upgrade apparatus through the connection device; and a first controller which controls the connection device to receive the processed image signal from the upgrade apparatus when the upgrade apparatus is connected through the connection device, wherein the power supply device is controlled by the upgrade apparatus connected through the connection device. | 08-01-2013 |
20150219879 | PHOTOGRAPHIC LENS AND ELECTRONIC APPARATUS - Provided are a photographic lens and an electronic apparatus including the photographic lens. The photographic lens includes a first lens having a negative refractive power; a second lens having a positive refractive power; a third lens having a negative refractive power and an image-side surface that is concave toward an image-side; a fourth lens having a positive refractive power; and a fifth lens having a negative refractive power. The first, second, third, fourth, and fifth lenses are arranged sequentially from an object-side to the image-side. Each of the first, second, third, fourth, and fifth lenses has at least one aspherical surface. | 08-06-2015 |
