Title: Color braun tube
Inventor: YAZUMI TOSHIHIKO
IPC: H01J29/32
Filed: 1981-10-07
Abstract: PURPOSE:To prevent any difference between the light outputs of the central and the peripheral parts of a fluorescent screen included in a shadow-mask-type color Braun tube by providing phosphor elements so that their emissional areas increase gradually from the central part to the peripheral part of the panel. CONSTITUTION:A color Braun tube is constituted by use of a fluorescent screen which consists of a number of phosphor elements, which are provided on a panel surface and exhibit different emissional colors by receiving stimulations of electron beams, and a black matter which fills the spaces formed between the above phosphor elements. Here, when the sizes of phosphor elements at the central part of the screen are supposed to be 100, the sizes of phosphor elements at the peripheral part of the screen are adjusted to the range between 90 and 110, thereby increasing the emissional area gradually from the central part to the peripheral part. As a result, any difference between the light outputs of the central part and the peripheral part of the fluorescent screen can be prevented without giving any influence upon a picture image. Besides, the visual discomfort of an observer which might be caused when the color Braun tube is used for display of letters or figures can be removed.

Title: Encoding and decoding method for moving image
Inventor: NAKAYA YUICHIRO
IPC: H04N19/625
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To prevent the accumulation of errors and to improve the picture quality of reproduced images by applying the composition of images which are performed by the motion compensations using the positive and negative rounding operations. SOLUTION: When the intensity value is interpolated for the composition of preatteted images, the motion compensations performing the positive and negative rounding operations are defined as the motion compensations which uses the positive and negative rounding operations respectively. The expected value of the rounding error of the P- frames is equal to that of the P+ frames in terms of the absolute value and is adverse to each other in terms of codes. Thus, it is possible to prevent the accumulation of rounding errors by making the P+ and P- frames appear alternately to a time base. In order to attain this process, the frames 503 and 507 are defined as P+ frames with the frames 505 and 509 defined as P- frames respectively. As a result, the picture quality of reproduced images can be improved.

Abstract: PURPOSE: To shorten the time for labeling processing and to economize memory areas required for labeling processing. CONSTITUTION: When scanning two-dimensional image data for each picture element, it is judged whether the value of concerned image data d(x, y) is '1' finding a linked component or not. Assuming that the value is '1', these concerned image data d(x, y) are adjacent to a circumscribed rectangle ru, to which downside adjacent data belong, of coordinate (x, y-1) and adjacent to a circumscribed rectangle rn, to which left side adjacent image data belong, of coordinate (x-1, y). Therefore, those two circumscribed rectangles ru and rl are integrated and defined as a circumscribed rectangle rn.  In this case, since slip extension in (x) direction is performed when integrating the circumscribed rectangles, the concerned image data to be next scanned are concerned image data d[x+width(rn)+1, y] for which the concerned image data d(x, y) are skipped from the (x) component just for the slip extension component width(rn)+1.
