Title: Decoder having adaptive block phenomenon removing function and method for removing/decoding adaptive block phenomenon
Inventor: SHIN TAE HWAN
IPC: H04N19/176
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To acquire an image of fine picture quality by adaptively estimating a spatial frequency component in accordance with a result whether a current block exists on the boundary of an object or not. SOLUTION: A block phenomenon judge 77 determines whether spatial frequency can be estimated or not by adding the number of nonzero spatial frequency components from an output signal of an inverse quantizer, and a boundary detector 78 constitutes a DC image not in a pixel area but in a spatial frequency area. Since the DC value in the spatial frequency area corresponds to eight times the mean value of a 8 *8 blocks in the pixel area, the detector 78 determines the boundary by dividing the DC value by 9 and obtaining the mean value of 8 * 8 blocks.  An adaptive spatial frequency component estimator 79 estimates a spatial frequency component based on an output signal from the detector 78 when a current block does not exist near the boundary, and wen the current block exists on the boundary of an object or on a position exerting influence upon the boundary, substitutes the DC value of the current block for the DC value of the block existing on the position exerting influence upon the boundary in a changed format and estimates the spatial frequency component.

Title: Display device
Inventor: KATAKURA KAZUNORI
IPC: G02F1/1335
Filed: 1991-12-12
Abstract: PURPOSE:To keep the display quality at an acceptable level despite gap generation due to movement of ferro-dielectric liquid crystal molecules by furnishing a shielding member for enclosing a void defective part produced at the periphery of the screen of a liquid crystal panel when the liquid crystal is driven. CONSTITUTION:Ferro-dielectric liquid crystal is encapsulated in the gap between a pair of electrode base boards 302, 304, and a liquid crystal panel is formed. When liquid crystal is poured into cell, the ferro-dielectric liquid crystal is unlikely to enter the peripheral area of a sealing member to result in remaining of fine voids, so that voids are easily produced in the peripheral area of sealing member due to movement of liquid crystal. Therefore, a shielding member is furnished for enclosing a liquid crystal void defective part which is generated at the periphery of the screen of the liquid crystal panel when the liquid crystal is driven. This shielding member is formed by extending a panel fixing plate 403, which is installed alongside the periphery of the liquid crystal panel, for a length required to enclose the defective part. The liquid crystal molecules in the part enclosed with the shielding member 403 are favorably put in such a condition as inclined relative to the rubbing direction toward the center of the display part.
