    摘要: Disclosed is a font pattern processor (GDP) including font pattern storing means (FPT1) for defining a font pattern and font pattern access parameter storing means (FDR) for storing parameters for making access to this font pattern storing means (FPT1). Address calculation is made on the basis of the font pattern access parameter and a pattern code supplied from outside to indicate a font pattern. The font pattern processor (GDP) can include pattern drawing attribute indicating means (FAR) for indicating the attributes of pattern drawing by the font pattern data thus read out.
    Thus, the present invention can process predeter­mined font data at a high speed inside it on the basis of the pattern code and can easily accomplish diversification of font patterns. Furthermore, the invention can improve freedom of pattern drawing on the basis of a predetermined original font pattern.

    摘要: An object of the present invention is to provide a character recognition apparatus for inferring the entire character string solely from a user-input handwritten keyword and displaying the inferred result as a candidate character string. The apparatus of the invention comprises: a word dictionary a6 storing word identification information and hierarchy information for layering a plurality of words into a hierarchy and for recognizing each of the words within the hierarchy; a character transition probability table a4 storing probabilities of transitions from any one character to another, and those pieces of the word identification information which correspond to combinations of characters resulting from the transitions; and an optimization unit for using the character transition probability table a4 in optimizing candidate character strings obtained by a recognition unit. The word dictionary a6 is searched for a word defined by the word identification information which corresponds to the optimized candidate character string, whereby the searched word is retrieved which applies to the hierarchy information and which has yet to be input.

    摘要: To reduce the hardware of the graphics computer in size and reduce the cost of the hardware by uniting the frame buffer and the main memory into one to process graphics data in the CPU. The frame buffer is arranged in the main memory, and a DMAC used to read pixel data from the frame buffer for display, a display used to receive the pixel data and display it on a display device such as an LCD, etc., and memories used to store the procedure used by the CPU to draw the pixel data in the said frame buffer are provided for the said graphics computer. Especially, the said memories are formed so that the single function procedure and the multifunction procedure can be selected to suit the drawing object in them. In addition, the single function procedure includes the line drawing procedure that uses data tables and the multivalue expansion procedure that uses a pattern table and a mask table. Since the frame buffer and the main memory are united into one, the CPU has come to process graphics data. Thus, the graphics computer hardware has been reduced in size and the cost of the hardware has been reduced.
