Abstract: A facsimile machine uses cut sheets ofrecording paper of a predetermined size. If data to be recorded requires a cut sheet of paper of a size larger than the cut sheets of paper of the predetermined size set in the facsimile machine for use, then upon completion of recording part of the data on one of the cut sheets of recording paper of the predetermined size, a predetermined number of lines recorded at the end of the one of the cut sheets of paper are once again recorded at the beginning of the next following cut sheet of paper prior to recording of the following portion of the data to be recorded. In this manner, since that portion of data, which is divided between the two consecutive pages, is recorded twice in accordance with the present invention, no information will be lost even if the data to be recorded is significantly long.
Abstract: A movement of a small picture block in a frame of video signals is provided by recursively applying a gradient method to a picture block in a present frame and a preceding frame to provide a series of sub-movements until said sub-movement decreases less than a predetermined value, and the resultant movement is obtained by the sum of the sub-movements. The present invention provides high accuracy in estimation of movement of a block in a picture as compared with a conventional gradient method, and is attractive in hardware implementation.
Abstract: A method and system for compressing television video signals for digital transmission allows full motion pictures to be transmitted. The analog signal is digitized and stored in a memory A in consecutive pixel value locations. The values of the color components of each pixel value are summed and stored in a memory B. In the second frame, the sum of each pixel value is compared with the sums stored in memory B. If the difference is greater than a filter number, then that particular pixel is transmitted by the control computer. The total number transmitted for each frame is compared to a maximum allowable data rate, and the filter number is adjusted accordingly.
Abstract: The present invention relates to a method and a system for composing patterns of predetermined less-frequently-used Chinese characters using an information processor, causing the memory occupation to be significantly decreased and the composing speed to be significantly increased and, furthermore, causing the Chinese character to be exactly, ornamentally generated. In accordance with the method and system, a first memory section stores patterns of frequently-used characters and a second memory stores command data. The command data is processed to obtain two patterns from the first memory section, one of the two patterns yielding a first pattern part and the other of the two patterns yielding a second part. The two pattern parts are then used to compose the patterns of less-frequently used Chinese characters.

Abstract: Methods and apparatus are provided for automatic and/or manual adaptive bandwidth compression of telemetry.An adaptive sampler (16) samples a video signal from a scanning sensor (12) and generates a sequence of sampled fields. Each field and range rate information from the sensor are then sequentially transmitted to and stored in a multiple adaptive field storage means (22). The field storage means (22) then, in response to an automatic or manual control signal, transfers the stored sampled field signals to a video monitor (24) in a form for sequential or simultaneous display of a desired number of stored field signals.The sampling ratio of the adaptive sample (16), the relative proportion of available communication bandwidth allocated respectively to transmitted data and video information, and the number of fields simultaneously displayed are manually or automatically selectively adjustable in functional relation to each other and detected range rate.

Abstract: A method is disclosed for computer composition of Nastaliq script and similar Ruka'ah script of the Urdu group of languages (Arabic, Persian, Punjabi, Pushto, Sindhi) in full conformance to rules of a script. Basic constituent elements of the characters of scripture are stored in a computer memory and these elements in response to user command are joined with each other, as required, to compose scripture according to a set of rules defined and stored in a rules dictionary. Combinations of characters that do not conform to the general rules contained in the dictionary are treated and executed as exceptional cases by the computer program. Moreover, an efficient mapping of Urdu characters to the existing QWERTY keyboard is achieved by matching character frequency of occurrence to finger agility, by pattern recognition features of similar characters, and by rationalizing the overall finger workload.
Abstract: There is provided an image forming device wherein a half-tone pattern having a recording portion and non-recording portion is formed on a recording medium, a value corresponding to the image density of the half-tone pattern is detected, and a high quality half-tone is obtained by controlling image signals by the above detection output or quantization means for the binary or multi-value conversion of image signals.
Abstract: A system for coding video signals e.g. television signals in block units is disclosed. The coding system comprises a synchronization detector for detecting a frame synchronization from the video signal, and a block former operative to divide the video signal in block units per a predetermined number of lines by using a picture frame synchronization signal detected by the synchronization detector as a reference. When the number of lines included in a block immediately before the subsequent picture frame synchronization signal is less than the predetermined number of lines, the block former designates the block as an ineffective block.

Abstract: A method is disclosed for thresholding the luminance component of color picture elements (pels) prior to compression. The method is most effective when used with discrete color images, such as documents having areas of nominally constant color. The method uses spatial information rather than histogram information to threshold the image data. Each scan line is defined as having a series of pel runs. A pel is considered to be in a run if its luminance is within a certain range of an average luminance based on preceding pels. Each run may end in a transition region wherein the luminance of each pel differs from the luminance of the preceding pel by more than a predetermined amount. Where a transition region is found, a local threshold is set based on the average luminance of the preceding run and of the following pel. All pels in the transition region are assigned a luminance value equal either to the average luminance of the preceding run or the actual luminance of the following pel.
