Abstract:
There are provided a plasma display apparatus and an image processing method thereof. The plasma display apparatus includes an inverse gamma correction unit performing inverse-gamma correction on image data applied from the outside; and a halftoning unit respectively applying different error coefficients to Red, Green, and Blue image data of the inverse-gamma corrected image data and performing error diffusion of the Red, Green, and Blue image data to which the different error coefficients are applied.
Abstract:
There are provided a plasma display apparatus and a Look-Up Table (LUT) used in the plasma display apparatus. The plasma display apparatus includes: a Look-Up Table (LUT) storage unit in which an object value corresponding to a variable of image data is stored; a data transmission unit transmitting decimal data corresponding to a decimal factor of the object value of the LUT; a data generator generating integer data corresponding to an integer factor of the object value in response to a change in the transmitted decimal data; and a data restoring unit restoring data corresponding to the object value using the generated integer data and the transmitted decimal data. Therefore, by improving a method for compressing data of a LUT, it is possible to reduce the time used to transmit the data of the LUT.
Abstract:
An apparatus and a method for synthesizing a MIDI based on a wave table are provided. According to the method, sound samples of a plurality of instruments stored in a wave table are compressed and stored so as to reduce the storage space required by the wave table. Bit streams for the samples are decoded to synthesize a MIDI when a specific instrument's sound samples are requested.
Abstract:
A method of fabricating a photomaskautomatically generates a microscopic supplementary pattern by selective sizing to reduce a product cost and by which a precise line width is provided in a manner of decreasing unnecessary microscopic supplementary patterns to raise precision of a photomask pattern. The method includes the steps of selectively carrying out a sizing on a main pattern to form a microscopic supplementary pattern with a difference of the corresponding sizing and selectively removing the microscopic supplementary pattern.
Abstract:
Provided is a distributed and asynchronous implicit token carrier sense multiple access/collision avoidance (CSMA/CA) protocol guaranteeing quality of service for both real time and non-real time traffic. The implicit token CSMA/CA protocol allocates a band in an entire bandwidth to voice traffic and allows the remaining bands to be used for data traffic. The implicit token CSMA/CA protocol includes applying a token passing protocol to transmit voice traffic in real time by having a band in an entire bandwidth allocated using a predetermined data frame and applying a CSMA/CA mechanism to transmit data traffic in non-real time by employing remaining bands not allocated to the voice traffic using another predetermined data frame.
Abstract:
A laundry dryer includes a dry drum in which laundry is loaded, a lower housing coupled to a rear wall of the dry drum by a rivet, an upper housing seated on the upper housing, and a journal bearing including a bearing inserted between the upper and lower housings and a shaft coupled to the bearing.
Abstract:
A rate 7/8 MTR code encoding/decoding method and apparatus. The encoding method includes: generating a rate-7/8 MTR code for inputting 7-bit data and outputting a predetermined 8-bit codeword; checking whether codewords satisfy a predetermined constraint condition by connecting the 8-bit codeword and a subsequent 8-bit codeword; and if the codewords do not violate the constraint condition, not converting the codewords. The decoding method includes: checking whether the codewords satisfy a predetermined MTR constraint condition by connecting a current 8-bit codeword c(k) and a subsequent 8-bit codeword c(k+1); if the codewords violate the constraint condition, converting the codewords, and if the codewords do not violate the constraint condition, not converting the codewords; and decoding each converted 8-bit codeword into 7-bit data using a predetermined MTR code. Data is reliably reproduced with high write density, and large amounts of data are stored in and reproduced from a magnetic recording information storage medium.
Abstract:
The present invention relates to a preparation method of solvent-free water-dispersible hydroxypropyl methyl cellulose phthalate nanoparticle, and more particularly, to a preparation method of solvent-free water-dispersible hydroxypropyl methyl cellulose phthalate nanoparticle, which is environment-friendly and advantageous in disintegration and dissolution when used as an enteric coating material, which is prepared by obtaining suitable hydroxypropyl methyl cellulose phthalate (HPMCP) particle through aqueous emulsification process and regulating content of remaining electrolyte through ion exchange process.
Abstract:
An inexpensive rain water collecting device which is easy to manufacture. The rain water collecting device provides an effective device which is adaptable to various umbrella tip sizes and avoids any bacterial growth problems. The rain water collecting device includes at least a reservoir having a first open end and a second open end, the first open end has an opening with an inner perimeter which is substantially equal to an outer perimeter of the umbrella tip, and the second open end has an opening with a perimeter which is greater than the inner perimeter of the opening of the first open end; a ferrule formed about the opening of the first open end; and at least one flow barrier about the second open end of the reservoir. After using an umbrella in the rain, it is collapsed. The rain water on the cloth of the umbrella then drains into the reservoir of the rain water collecting device. The flow barrier(s) prevent the rain water contained in the reservoir from splashing out while the collapsed umbrella (although pointed substantially downward) is moved about.
