Disclosed are an apparatus and method for estimating a distance using a dual off-axis color filter aperture (DCA). An object detection unit is configured to detect an object from an image taken by a camera having the DCA equipped with a first filter having a first color and a second filter having a second color complementary to the first color. A color shifting value calculation unit is configured to calculate a color shifting value (CSV) using a color shift property between color channels of the image in a region corresponding to the detected object. A distance estimation unit is configured to estimate a distance from the camera to each point of the object based on the calculated CSV and camera parameters including a focal distance of the camera, a focal plane of the camera, and a position of the aperture.

A parallel-processing apparatus and method provide for synchronous replication in a database management system (DBMS). During synchronous replication into the active node and the standby node in the DBMS, replications of transactions are parallelized in units of transactions, thereby improving a performance of the DBMS, guaranteeing atomicity and consistency of the transaction, and solving the deadlock state which may occur in parallel-processing.

Databases of an active node and a standby node of a main memory database management system (MMDBMS) are managed so as to prevent loss of a transaction caused by failure of any one of the active node or the standby node. The MMDBMS is configured to prevent data mismatch between the active node and the standby node when failure of any one of the active node and the standby node occurs. In case of failure of one of the nodes, log information from the other node is obtained to recover the failed node.

A method and system for adjusting a gray-scale level of an LCD device. The method includes: checking a default gray-scale value A; comparing default brightness value YA with a target brightness value YX; inputting a trial gray-scale value B; and outputting a target gray-scale value X. The method employs a preselected Similarity of Triangles technique. The system employs a image-capturing unit determining screen brightness and a control unit using a preselected Similarity of Triangles technique to adjust the gray-scale level of a connected display device, reducing a single-screen-capture gray-scale level adjustment interval to about 1.8 to 2.1 seconds.
