Abstract: The present disclosure relates to a CNT X-ray source apparatus, and more particularly, to a CNT X-ray source apparatus configured to maximize utilization of the internal space of a CNT X-ray tube body, having grooves made of an insulating material, and provided with a base portion for supporting a plurality of electrodes. With this configuration, mass production is possible. The CNT X-ray source apparatus of the present disclosure includes a cathode electrode; an emitter provided on the cathode electrode and responsible for emitting electrons; a gate electrode disposed above the cathode electrode and spaced apart from the cathode electrode by a predetermined interval; a focusing electrode for preventing scattering of electrons emitted from the emitter; and a base portion responsible for supporting one or more of the cathode electrode, the gate electrode, and the focusing electrode and formed of an insulating material. In this case, one or more grooves for accommodating at least one of the cathode electrode, the gate electrode, and the focusing electrode are formed in the base portion.

Abstract: Disclosed are a method and an apparatus for masking a privacy region based on a monitored video image. The method for masking a privacy region based on a monitored video image, includes: extracting a target object from the video input from an video collector to detect a privacy masking region from the extracted target object; and graphic-processing only the detected privacy masking region of the target object to hide the privacy masking region without transforming an original of the input video, thereby easily hiding the privacy region without transforming original video captured when monitoring an video image of a monitoring target region not to expose the privacy region.
