Abstract: A shoes care device includes an inner cabinet and a module housing. A blowing part, a heating part, and a dehumidifying part are jointly accommodated in a module chamber inside a module housing, and the module housing is detachably coupled to a lower side of the inner cabinet. A shoes care device having a structure in which condensed water generated while passing through the blowing part, the heating part, and/or the dehumidifying part can be prevented from being leaked, and it is advantageous for leakage management, and the module housing and a component accommodated therein are easily managed and replaced.

Abstract: Provided is a method of compressing an occupancy map of a three-dimensional (3D) point cloud, and more specifically, a method of compressing an occupancy map of a point cloud in which an occupancy map image of a point cloud existing in a 3D space is compressed based on a compression quality or a patch-by-patch inspection method of the occupancy map image so that compression distortion is minimized when reconstructing the compressed occupancy map image so as to remarkably improve the quality of a reconstructed occupancy map image.

Abstract: Provided is a display device. The display device includes a first base portion, a second base portion facing the first base portion, a light emitting layer disposed on one surface of the first base portion and emitting first light, a first wavelength conversion pattern disposed on the light emitting layer and converting the first light into second light having a different wavelength from the first light, a first color filter overlapping the first wavelength conversion pattern on one surface of the second base portion and spaced apart from the first wavelength conversion pattern, and an air layer interposed between the first wavelength conversion pattern and the first color filter.

Abstract: A CCD (charge coupled device) camera system capable of a multi-media response includes: a prism which disperses according to frequency optical signals of an object focused on the prism by a lens; first and second CCDs for converting optical signals which are imaged by the prism into electrical signals, and having mutually different color filter arrays consisting of a complementary color stripe pattern and an effective number of pixels corresponding to the international standard; first and second sample and hold circuits for removing noise from the output video signals of the first and second CCDs; first and second analog to digital converters for converting the analog video signals of the first and second sample and hold circuits into digital signals; and a CCD video signal processor for calculating the sum of and the difference between the two sets of signals output by the first and second sample and hold circuits so as to generate brightness signals and color signals.
