摘要:
The present invention relates to hydrogel particles coated with lipid, which are made from dispersing hydrogel particles in an organic solvent in which lipids are dissolved, and to a method for manufacturing same. Unlike the existing method for manufacturing hydrogel core vesicles, the present invention can effectively manufacture same by using an emulsification method, without involving the steps of chemical treatment of the surface of hydrogels or dilution, thereby facilitating mass production and preventing the decrease of drug encapsulation efficiency. The present method could be widely used for research on delivery carriers of oil/water-soluble active material or cell structure reproduction and more particularly, a keratinocyte mimetic of the present invention containing natural moisturizing factors can contain a large quantity of bound water for a long time, thereby exhibiting superior capability to retain moisture and moisturize, and providing a composition for an ingredient in cosmetics for moisturizing.

摘要:
For spatial resolution conversion of an image signal, a magnitude of a motion vector is compared to a threshold value. Single channel interpolation is performed if the magnitude of the motion vector is greater than a threshold value, and multi-channel interpolation is performed otherwise. In addition, single channel interpolation is performed for spatial resolution conversion of any frame that does not refer to another frame.

A synchronization detector of a video signal processor includes a line buffer, a parameter extraction unit and synchronization detection unit. The line buffer sequentially stores a digital video signal corresponding to an input analog video signal, line by line of the input analog video signal. The parameter extraction unit continuously extracts horizontal synchronization parameters from the digital video signal stored line by line and continuously extracts vertical synchronization parameters from a portion of the digital video signal stored line by line. The synchronization detection unit generates horizontal and vertical synchronization signals of the input analog video signal using time information related to local minimum values of the horizontal synchronization parameters and time information related to local minimum values of the vertical synchronization parameters.
摘要:
Sync positions are detected from a video signal. The detected sync positions are processed (e.g., averaged) to generate modified sync positions. The detected sync positions and the modified sync positions are selectively used to sample and synchronize a color signal derived from the video signal. For example, the detected sync positions and the modified sync positions may be selectively used to sample and synchronize the color signal responsive to differences between the modified sync positions. The invention may be embodied as apparatus and/or methods.

A digital processing system and method for tracking a subcarrier included in a video signal are provided, where a phase comparator tracks the phase of a color burst signal based on predetermined supposed phases, Y/C separation and demodulation are carried out based on a compensation phase that is updated by a phase compensator in response to the tracked phase, and the Y/C separation and demodulation are performed based on a compensation frequency determined by a frequency compensator by checking short-term and long-term variations in the updated compensation phase.
摘要:
A digital video signal processing apparatus and method for adaptive spatio-temporal Y/C separation in multiple directions. In the digital video signal processing apparatus, an adaptive three-dimensional band pass filter (3D BPF) performs Y/C separation using local comb filtering/1D band pass filtering when the edge direction is fixed vertically/horizontally according to spatio-temporal local characteristics of an image using spatio-temporal filters. When the edge direction is not fixed horizontally/vertically, the 3D BPF performs 2D band pass filtering in all directions. Thus, the 3D BPF continuously carries out comb filtering, 1D band pass filtering and 2D band pass filtering according to the spatio-temporal local characteristics of the image.

A disc cartridge is provided. The disc cartridge includes: a lower housing having a window for allowing a recorder or reader to access to a read-out surface of a disc; and an upper housing coupled to the lower housing to ejectably receive the disc between the lower housing and the upper housing, and having at least a portion rotatable up and down with respect to one side of the lower housing until the disc can be ejected.
摘要:
A method and apparatus for recording/reproducing data is disclosed. The apparatus for recording/reproducing data comprises a diffraction element splitting light diffracted or reflected from a recording medium into a main beam and first and second sub beams, the main beam and the first and second sub beams having no interference from one another; a light-receiving part detecting the main beam and the first and second sub beams; and a controller controlling a position of the diffraction element based on at least one light capacity of the detected beams or the detected position.
