The present invention relates to an electromagnetic contactor, and more particularly, to an electromagnetic contactor for star-delta driving, which is capable of rapidly and safely switching a connection of a 3-phase motor from a star connection to a delta connection and simplifying configurations of a connection circuit and an opening/closing device. According to the electromagnetic contactor for star-delta driving and a control device thereof of the present invention, the connection of the 3-phase motor can be switched rapidly and safely from the star connection to the delta connection, and the configuration of the connection circuit and a control circuit of a power supply thereof and a magnetic switch configuration can be simplified, and thus, there is an effect of saving space by reducing the size and weight of a product and reducing the numbers of power wirings and control circuit wirings. In addition, a magnetic switch between star and delta connections is interlocked by using a timer and an auxiliary contact, so as to improve the convenience of an operator and reduce construction time. In addition, because a timer base and the control device are ready-made in the form of manufactured goods, it is easy to use the products and there is very little risk of causing a misconnection in the control device. Thus, there are effects of improving the safety of a construction operator at a construction site and a general user, and improving driving components and circuit protection.

This invention provides a method to transform 3D object points onto 2D image points for linear pushbroom images. The problem is decomposed to the problem of finding sensor line coordinates and the problem of finding sensor column coordinates from linear pushbroom collinearity equations. The procedures to solve the problem are as follows. First, assume an initial value for image line coordinate to be sought for and using this value, calculate the sensor attitude. Next, assume the sensor attitude is constant and calculate a new image line coordinate satisfying linear pushbroom collinearity equations. Next, update the initial value with the image line coordinate calculated and continue the procedures until the difference between an initial value and a new value calculated becomes smaller than a threshold. If the different between an initial value and calculated value is smaller than a threshold, accept the calculated value as the sensor line coordinate. After finding the sensor line coordinate, calculate the sensor column coordinate satisfying linear pushbroom collinearity equations.

A prediction mode determining method in scalable video coding based on a structure of multiple layers is provided. The prediction mode determining method includes: deriving a coded block pattern (CBP) value of a luma component for a 16×16 mode of an encoding target picture; determining first candidate modes for the encoding target picture according to the derived CPB value; and determining a final prediction mode for the encoding target picture based on the determined first candidate modes. According to the present invention, encoding efficiency may be improved, and complexity may be reduced.
