Abstract
A plotter system has a data converting portion for converting image data to raster data. An intermediate memory temporarily stores the converted data, while a plot portion draws an image based upon the data outputted from the intermediate memory.
Claims19
A plotter system, comprising:
- means for converting image data to raster data;
- an intermediate memory for temporarily storing said converted image data;
- means for drawing an image based upon data outputted from said intermediate memory;
- and
- means for controlling a drawing speed of said drawing means corresponding to an amount of data remaining in said intermediate memory.

A plotter system, comprising:
- means for converting image data to raster data;
- an intermediate memory for temporarily storing said converted image data;
- means for drawing an image based upon data outputted from said intermediate memory;
- means for determining an amount of data remaining in said intermediate memory;
- and
- means for controlling a drawing speed of said drawing means based upon information from said data remaining determining means, such that when an amount of data remaining is large, said drawing speed of said drawing means is increased, while when said amount of data remaining is small, said drawing speed is decreased.

A plotter system, comprising:
- means for converting image data to raster data;
- an intermediate memory for temporarily storing said converted image data;
- means for drawing an image based on data outputted from said intermediate memory;
- data remainder detecting means for detecting an amount of data accumulated in said intermediate memory;
- and
- means for controlling a drawing speed for increasing the drawing speed of said plot means when the amount of data remaining is large and decreasing the drawing speed when the amount of data remaining is small.
3 more elements
A plotter system, comprising:
- means for converting image data to raster data;
- an intermediate memory for temporarily storing said converted image data;
- plot means having means for scanning a laser beam onto a drawing object, and means for transferring said drawing object in a direction perpendicular to the scanning direction of said laser beam;
- means for detecting an amount of data remaining in said intermediate memory;
- and
- means for controlling a drawing speed for increasing said drawing speed of said plot means when said amount of data remaining is large and decreasing the drawing speed when said amount of data remaining is small, so that a product between a timewise interval of the scanning by said scanning means and a moving speed of said transferring means becomes constant.
3 more elements
A system for drawing an image, comprising:
- means for converting image data to raster data;
- means for temporarily storing said converted image data;
- a printing device for drawing an image based upon data outputted from said storing means;
- and
- means for controlling said printing device corresponding to an amount of data remaining in said storing means.
2 more elements
A system for drawing an image, comprising:
- means for converting image data to raster data;
- means for temporarily storing said converted image data;
- a printing device for drawing an image based upon data outputted from said storing means;
- and
- means for controlling said printing device, wherein said controlling means controls a drawing speed of said printing device in response to an amount of data in said storing means.
