Abstract: Disclosed are methods, apparatuses, and systems for encoding and decoding an image. The present invention provides an intra prediction unit that receives an input image, calculates a correlation between a Luma area block and Chroma area block in the input image in intra prediction, removes high frequency ingredients by low-pass filtering an encoded luma pixel based on the calculated correlation, and generates a prediction block by applying an LM chroma mode, which is an extended chroma mode technique, to the luma pixel removed therefrom the high frequency ingredients.

Abstract: Provided is a method of forming a transition metal chalcogenide thin-film and the method includes preparing a first substrate having formed thereon a transition metal-containing precursor thin-film; displacing a second substrate separately with a constant distance from the first substrate by using a bridge unit while the second substrate is facing the first substrate, thereby securing a gas flowing path between the first substrate and the second substrate; heating the first and second substrates to a reaction temperature; and introducing a chalcogen-containing gas from an end of a reactor, such that the chalcogen-containing gas flows via the path.

Abstract: A method of forming an oxide semiconductor device may be provided. In the method, a substrate comprising a first major surface and a second major surface that faces away from the first major surface may be provided. An oxide semiconductor device may be formed over the first major surface to provide an intermediate device, and the semiconductor device may comprise an oxide active layer. The intermediate device may be subjected to ultraviolet (UV) light (e.g., ultraviolet ray irradiation process) for a first period, and subjected to heat (e.g., thermal treatment process) for a second period. The first and second periods may at least partly overlap.
