Abstract: An electronic device is provided. The electronic device includes a memory configured to store a high-speed video captured with a first number of frames per second and a processor configured to be electrically connected with the memory. The processor is configured to detect an amount of image variation based on at least one of the first number of frames and generate a slow motion interval, a playback time of which is extended, by dividing or sampling the first number of frames into a second number of frames which are less than the first number of frames with respect to a video interval having an amount of image variation which meets a specified condition.

Abstract: The present invention provides a positive electrode active material prepared using a preparation method including mixing lithium complex metal oxide particles with a nanosol of a ceramic-based ion conductor and heat treating the resultant to form a coating layer including the ceramic-based ion conductor on the lithium complex metal oxide particles, thereby forming a coating layer including a ceramic-based ion conductor to a uniform thickness on a lithium complex metal oxide particle surface, and as a result, capable of minimizing capacity decline and enhancing a lifespan property when used in a secondary battery, a method for preparing the same, and a lithium secondary battery including the same.

Abstract: The present invention provides a positive electrode active material prepared using a preparation method including mixing a precursor of a metal for a positive electrode active material with a nanosol of a ceramic-based ion conductor to adsorb the nanosol of the ceramic-based ion conductor on the precursor surface, and mixing the nanosol of the ceramic-based ion conductor-adsorbed precursor with a lithium raw material, and heat treating the resultant to prepare a positive electrode active material, and thereby having greatly increased structural stability by the lithium complex metal oxide present on the surface as a metal element forming the ceramic-based ion conductor being uniformly doped, and as a result, capable of significantly enhancing capacity, a rate property and a cycle property of a battery, a method for preparing the same, and a lithium secondary battery including the same.

Abstract: A method of erasing a power calibration area (PCA) for determining optimum power, including applying a command for recording data, detecting a non-recorded PCA area for performing optimum power control (OPC), and when all the PCA area is used and no non-recorded PCA area is detected, performing erasing of the PCA area at least twice. Accordingly, since the PCA area is erased at least twice, reliability of the optimum recording power determined by performing the OPC is much improved.
