Abstract
An image forming apparatus includes a storage unit configured to store a rendering image having a plurality of tones, a communication interface unit configured to receive print data, a rendering unit configured to render the received print data to a bitmap image, a mergence unit configured to merge the bitmap image and the rendering image into a single mergence image, a binary coding unit configured to perform halftoning for the generated mergence image to generate binary data, and a print engine unit configured to form an image on a paper by using the generated binary data.
Claims23
An image forming apparatus comprising:
- a storage unit configured to store a rendering image having a plurality of tones;
- a communication interface unit configured to receive print data;
- a rendering unit configured to render the received print data to a bitmap image;
- a mergence unit configured to merge the bitmap image and the rendering image into a single mergence image prior to generating binary data corresponding to either of the bitmap image and the rendering image;
- a binary coding unit configured to perform halftoning on the generated mergence image and to generate binary data corresponding to the mergence image, the binary data corresponding to the mergence image having fewer tones than either of the rendering image and the bitmap image;
- and
- a print engine unit configured to form an image on a paper by using the generated binary data.
A method of forming an image with an image forming apparatus, the method comprising:
- receiving print data;
- rendering the received print data to a bitmap image;
- merging the bitmap image and a rendering image having a plurality of tones prestored in the image forming apparatus to generate a single mergence image prior to generating binary data corresponding to either of the bitmap image and the rendering image;
- performing halftoning on the generated mergence image and generating binary data corresponding to the mergence image, the binary data corresponding to the mergence image having fewer tones than either of the rendering image and the bitmap image;
- and
- forming an image on a print paper by using the generated binary data.
An image forming apparatus comprising:
- a mergence unit configured to merge a currently rendered image and a previously rendered image into a single mergence image prior to generating binary data corresponding to either of the currently rendered image and the previously rendered image;
- a binary coding unit configured to generate binary data corresponding to the mergence image by performing halftoning on the mergence image, the binary data corresponding to the mergence image having fewer tones than either of the currently rendered image and the previously rendered image;
- and
- a print engine unit configured to form an image using the generated binary data.
A method of forming an image, the method comprising:
- merging a currently rendered image and a previously rendered image to generate a single mergence image prior to generating binary data corresponding to either of the currently rendered image and the previously rendered image;
- generating binary data by performing halftoning on the mergence image, the binary data corresponding to the mergence image having fewer tones than either of the currently rendered image and the previously rendered image;
- and
- forming an image using the generated binary data.
