20090174436 | INPUT SIGNAL LEVEL DETECTION APPARATUS AND METHOD - A method and an input signal level detection apparatus that correctly detect a level of an input signal while consuming low power apparatus including: a full-wave rectifier outputting a full-wave rectified waveform by performing a full-wave rectification on a first signal corresponding to an input signal, and on a second signal having a phase difference of 180 degrees from the first signal; a common voltage detector detecting a common voltage of the first signal and the second signal; and a level detection unit detecting a level of the input signal, based on a subtraction result obtained by subtracting the common voltage from the full-wave rectified waveform. | 07-09-2009 |
20110141331 | MULTI-STEP EXPOSURE METHOD USING ELECTRONIC SHUTTER AND PHOTOGRAPHY APPARATUS USING THE SAME - A multi-step exposure method using an electronic shutter and a photography apparatus using the same are provided. The photography apparatus includes an image sensor, and a control unit which divides an area of the image into a first area and a second area using brightness information of the acquired image, and controls so that a first row group and a second row group of the second area have different exposure times. As a result, an image with a wider dynamic range is provided. | 06-16-2011 |
20110149129 | MULTI-STEP EXPOSED IMAGE ACQUISITION METHOD BY ELECTRONIC SHUTTER AND PHOTOGRAPHING APPARATUS USING THE SAME - A multi-step exposed image acquisition method by an electronic shutter and a photography apparatus using the same are provided. The photography apparatus includes a controller configured to divide an image sensor into a plurality of areas and separately control an exposure time with respect to the plurality of areas of the image sensor and a display configured to display an image on which the exposure times for the areas has been controlled. Accordingly, a multi-step exposed image can be acquired from an image having varying brightness. | 06-23-2011 |
20110234835 | APPARATUS FOR AUTO-FOCUSING DETECTION, CAMERA APPLYING THE SAME, AND METHOD FOR CALCULATING DISTANCE TO SUBJECT - An apparatus for auto-focusing detection, a camera applying the same, and a method for calculating a distance to a subject are disclosed. The camera calculates a focusing control state based on synthetic image data output as an image passing through a pupil split unit provided with a filter arranged at one or more of the at least two holes as taken by an image pickup unit. | 09-29-2011 |
20110236007 | IMAGING APPARATUS PERFORMING AUTO FOCUSING FUNCTION WITH PLURALITY OF BAND PASS FILTERS AND AUTO FOCUSING METHOD APPLIED TO THE SAME - An imaging apparatus and an auto focusing method are provided. A plurality of focus signal values are calculated for a plurality of frequency bands of a captured image signal. An amount of defocus of a focus lens is calculated based on focus signal values calculated for two positions. A position of the focus lens is controlled depending on the calculated amount of defocus. Thereby, the imaging apparatus can detect a focus at higher speed. | 09-29-2011 |
20120212634 | PHOTOGRAPHING APPARATUS AND PHOTOGRAPHING METHOD THEREOF - A photographing apparatus includes a detection unit for detecting light exposure error resulting from a difference in a moving characteristic between a mechanical rear curtain and an electronic front curtain using data of some area constituting an image sensor, a signal generating unit for generating a reset signal of the image sensor, and a control unit for controlling to correct a moving characteristic of the electronic front curtain using the detected light exposure error and generate a reset signal of the image sensor according to the corrected moving characteristic. Accordingly, a moving characteristic of an electronic front curtain may be conveniently corrected by a user. | 08-23-2012 |
20160042526 | IMAGING APPARATUS AND METHOD FOR CONTROLLING THE SAME - An imaging apparatus is provided, which includes an image sensor which includes a plurality of image pixels and a plurality of sensing pixels, and is configured to capture images through collection of light that is incident through a lens and the plurality of phase sensing pixels; and a processor configured to divide a region of interest of the image sensor into a plurality of sub-regions of interest, calculate disparity information of objects that correspond to the plurality of sub-regions of interest using at least one of the plurality of phase sensing pixels included in the plurality of sub-regions of interest, and determine a focal region in the region of interest on the basis of the disparity information. Accordingly, user convenience is increased. | 02-11-2016 |
20160044258 | IMAGING APPARATUS AND IMAGING METHOD THEREOF - An imaging apparatus and an image method thereof are provided. The imaging apparatus includes an image pickup including a pixel, the pixel being configured to accumulate a charge. The imaging apparatus further includes an image processor configured to perform image processing based on the accumulated charge to generate an image, a signal generator, and a controller configured to determine an exposure pattern of the pixel, and control the signal generator to generate a reset signal based on the determined exposure pattern. The pixel is configured to accumulate the charge based on the reset signal. | 02-11-2016 |
