A method and system for acquiring a phalange edge image using an X-ray image of a hand are provided. The method includes: selecting a region of interest from an X-ray image of the hand; acquiring a soft tissue background gray level removed image by removing a soft tissue background gray level from the region of interest; and extracting a phalange edge image from the soft tissue background gray level removed image.

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.

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.
摘要:
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.
摘要:
An apparatus and method for improving the performance of an error correction code against the effects of error waves in a Multi-Input Multi-Output (MIMO) communication system are provided. In a receiver of the MIMO communication system, a Minimum Mean Square Error (MMSE) receiver unit estimates transmitted signals from at least two paths using signals received at each of receive antennas, a signal deprocessor selects one of the estimated signals, stores the other estimated signal, assigns weighting values to the selected signal and a previous detected signal, combines the weighted signals, and detects transmitted data from the combined signal, a signal reproducer reproduces a transmitted signal from the detected transmitted data, and a subtractor updates the received signals by subtracting the reproduced transmitted signal from the received signals and provides them to the MMSE receiver unit.

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.
