Abstract: For converting a pattern which consists of a matrix of binary pattern elements and, in particular, represents a pseudo half-tone picture, into a smaller pseudo half-tone picture, the picture to be reduced is divided into fields and the picture elements having one binary value in each field are counted, which produces a reduced quasi-genuine grey-tone picture. This grey-tone picture is compared with weightings of a weighting matrix repeatedly applied, and the results of the comparison then provide the binary picture elements of the reduced pseudo half-tone picture. Further reduction is achieved by omitting fields or grey tone picture elements at regular intervals from the fields of the matrix of the picture to be reduced or from the picture elements of the grey-tone picture generated in the meantime. …<IMAGE>…

IPC: H04N1/327
Filed: 1990-03-09
Abstract: This invention allows unmodified CCITT Group 3 and 4 facsimile transceivers to interactively select and retrieve facsimile pages from a shared facsimile data base FAX server system ("FAX server"). The remote facsimile transceiver user marks a paper selector sheet form using a pencil or pen. The selector sheet is transmitted via the remote facsimile transmitter, preferably in a turn-around polling mode, to the FAX server unit. The FAX server unit processes the facsimile signal rapidly, interpreting the selector sheet and selecting the pages desired to be retrieved prior to the normal CCITT Recommendation T.30 timeout, which would otherwise abort the line connection. The invention allows the requested information to be returned during the same telephone call. If turn-around polling is not available, then the FAX server initiates alternative strategies culminating in an automatic callback with the information desired. The capability created allows facsimile transceivers to be used as interactive terminals for selective retrieval of text and graphics, without requiring alphanumeric keyboard interaction or the need for manual intervention.

Abstract: A method of driving a matrix-type liquid crystal display device utilizing a liquid crystal layer sandwiched between a plurality of scanning electrodes and a plurality of signal electrodes extending generally perpendicular to the scanning electrodes, which comprises the steps of erasing a display screen by bringing it into either a light transmitting state or a light scattering state, writing by which pixels each at a point of intersection between the scanning and signal electrodes are selectively reversed in optical state, and retaining each of the pixels in the optical state once assumed immediately after the writing step. During the erasing step, all of the pixels are applied with a high alternating voltage or a high direct current voltage. During the writing step, the scanning electrodes are line-sequentially selected and the signal electrodes are applied with a signal of a waveform effective to apply a high voltage to some of the pixels desired to be reversed in optical state and a low voltage to some of the pixels desired to be retained. During the retaining step, a low alternating voltage or a low direct current voltage is applied to all of the pixels. One of the voltage wave applied to the pixels during the writing step and that applied thereto during the erasing step is high and low, respectively.
