摘要： PURPOSE:To bring a segment of a multicolor to picture drawing by a single picture drawing processing by storing the number of sub-segments in the segment, a picture element value corresponding to each sub-segment and the number of picture elements, reading out successively the number of picture elements and the picture element value, and executing a processing for repeating the picture drawing processing by the number of picture elements with respect to each picture element value. CONSTITUTION:At the time of bringing a segment to multicolor display, the number of sub-segments is stored in a sub-segment number store means 121, a picture element value for showing a color of each bus-segment is stored in a picture element value store means 125, and the number of picture elements for showing the length of each sub-segment is stored in a picture element number store means 123. Subsequently, this picture element value and the number of picture elements are read out, and a picture drawing processing for writing the picture element value in a display memory 113 is repeated by the number of picture elements. Also, this picture drawing processing is repeated in accordance with the number of sub-segments. In such a way, picture drawing of the segment of a multicolor can be executed by a single picture drawing processing.

摘要： PURPOSE:To improve the selection efficiency of a graphic by deciding an ellipse arc or an ellipse area which is not evidently clipped without discomposing them and saving time required for the processing of them. CONSTITUTION:A circumscribed quadrilateral arithmetic operation part 5 calculates a smallest parallelogram including each ellipse. Then, a clipping decision part 6 compares the calculated parallelogram and each data in a display area setting part 4 and excludes the ellipse or the ellipse arc which is not evidently needed to be clipped from an object to be processed.

摘要： PURPOSE:To improve processing speed concerning the character display control system to directly write characters or the like onto a frame memory by a CPU. CONSTITUTION:This system is composed of a calculating means 1A to calculate accessable (n) characters according to the access unit of the CPU and character width, preparing means 1B to prepare one line pattern data for the (n) characters in a register 6 by moving the font data of the one line pattern of the (n) characters, which are read out, for each character width, and writing means 1C to write the one line pattern data prepared in the register 6 only for the height of the character into a frame memory 7 corresponding to the (x, y+m) coordinates of a character.

摘要： PURPOSE:To shorten a time required for processing by omitting the complicated process of polygon discomposition for an ellipse which is not evidently picked. CONSTITUTION:A parallelogram arithmetic operation part 5 calculates the value of a coordinate axis of the vertex of a parallelogram. Based on the calculated value of the coordinate axis, the vertex and a desired picking area are decided whether one of them includes the other or not by a vertex decision part 6. Then, a side.crossing decision part 7 decides whether the crossed side exists or not and executes usual decision operation when even one crossed side exists. On the other hand, when it does not exist, the vertex and the desired picking area which have the included relation is picked and those which do not include the relation is excluded.

摘要： PURPOSE:To simplify the processing of an operating system OS part of a system processor and to improve the processing speed of a character display device by designating a display start position, the variable horizontal body face value, and the variable vertical body face value and then deciding the arrangement of characters. CONSTITUTION:When a basic character size is designated by a user program or an operator, an OS part of a system process 11 instructs the character size to a display start position P as a letter face (lx X ly) and also the letter face arrangement to a display control processor respectively. Thus the display control processor change one or both of (x) and (y) direction coordinates of the mark P based on the body face sizes Bx and By and then arranges the letter faces. Under such conditions, the body face sizes are variable and therefore various character pitches or line pitches are available. As a result, the processing is simplified for the OP part of the processor 11 and the processing speed is im proved for a character display device.

摘要： PURPOSE:To attain a high speed processing by inspecting whether a graphic in question enters a window before a division to a rectangular area or not before a graphic clipping processing for every rectangular area and excluding the graphic which does not enter as one which is not an object. CONSTITUTION:At the time of clipping segments (graphic) L1-L3 on the window 14 (rectangular area), the clipping processing is carried out on all the window 14 including a part con hidden by the window 12 (whether segments L1-L3 enter the 14 or not is checked) and the segment (graphic) L3 which does not enter the window 14 is eliminated. Thereby, it is not necessary to execute the clipping on a wasteful rectangular area, so that an efficient and high speed clipping processing can be carried out.
