Abstract: An event sensing method using a frequency component in a surveillance camera comprises the steps of: obtaining at least one of a plurality of frequency components for a first frame of a digital image and at least one of a plurality of frequency components for a second frame after the first frame of the digital image; and sensing whether an event occurs in a digital image corresponding to the second frame by using the at least one of the plurality of frequency components for the first frame and the at least one of the plurality of frequency components for the second frame.

Abstract: The present invention relates to a method of managing cookie information in a user terminal and an application thereof. Specifically, the present invention relates to a cookie information management method and an application thereof, which can provide information needed for target advertisement to a service server in the future by matching a subject using an application and a subject using a web in the user terminal as one user using cookies and, furthermore, allowing the user terminal to integratedly manage the cookie information according to using an application and a web.

Abstract: A data storage device includes a data storage medium; a micro control unit (MCU) connected to a host through a first interface method and configured to control the data storage medium in response to a request of the host; and a buffer memory connected to the host through a second interface method, connected to the MCU, and controlled by the MCU and the host, respectively.

Abstract: Disclosed herein is an apparatus for monitoring an image with low power including: an image sensor unit; a low compression unit encoding image data acquired by the image sensor unit with a first compression rate; an event sensor unit generating an event signal when an event is sensed; a high compression unit operated by receiving the event signal and encoding the image data of the image sensor unit and the low compression unit with a second compression rate higher than the first compression rate; and a memory unit storing the image data encoded by the low compression unit and the high compression unit.
