Abstract
An image processing device includes a document scanning unit, a color image processing unit, a monochrome image processing unit and a memory. A processing by the color image processing unit and a processing by the monochrome image processing unit are carried out simultaneously. The document scanning unit scans an original document. The color image processing unit converts scanned data obtained by the document scanning unit into color image data. The monochrome image processing unit converts the scanned data obtained by the document scanning unit into monochrome image data. The memory stores both the color image data and the monochrome image data.
Claims24
An image processing device, comprising:
- a document scanning unit which scans an original document;
- a color image processing unit which converts scanned data obtained by the document scanning unit into color image data;
- a monochrome image processing unit which converts the scanned data obtained by the document scanning unit into monochrome image data;
- and
- a memory which stores both the color image data and the monochrome image data;
- wherein a processing by the color image processing unit and a processing by the monochrome image processing unit are carried out simultaneously.
An image processing device, comprising:
- a first input unit which inputs color multilevel image data;
- a color data compressing unit which carries out a compressing process of the color multilevel image data input from the first input unit and generates compressed color image data;
- a monochrome conversion unit which converts the color multilevel image data input from the first input unit into monochrome image data;
- a monochrome data compressing unit which carries out a compressing process of the monochrome image data generated by the monochrome conversion unit and generates compressed monochrome image data;
- a coupling unit which couples the compressed color image data and the compressed monochrome image data generated from the same color multilevel image data and generates coupled image data;
- a first storage unit which stores the coupled image data generated by the coupling unit;
- a second storage unit which temporarily stores the monochrome data generated by the monochrome conversion unit;
- an extracting unit which extracts compressed monochrome image data from the coupled image data retrieved from the first storage unit;
- a first monochrome output unit which outputs one of the compressed monochrome image data and the monochrome image data;
- a second monochrome output unit which outputs one of the compressed monochrome image data and the monochrome image data;
- and
- a control unit which controls to simultaneously carry out a first processing and a second processing, wherein in the first processing, for the coupled image data previously stored in the first storage unit, the monochrome data extracted by the extracting unit is output from the first monochrome output unit, and in the second processing, the monochrome data generated from the color multilevel image data input from the first input unit is output from the second monochrome output unit.
An image processing device, comprising:
- a multilevel decompression unit which executes a decompression process of compressed color image data input from a remote device;
- a monochrome conversion unit which converts color multilevel image data obtained by the multilevel decompression unit into monochrome image data;
- a monochrome data compression unit which executes a compressing process of the monochrome image data generated by the monochrome conversion unit and generates compressed monochrome image data;
- and
- a coupling unit which couples the compressed color image data and the compressed monochrome image data generated from the same color multilevel image data and generates coupled image data.
A data structure embodied in a computer-readable medium and executable by a processor, comprising:
- a Joint Photographic Experts Group (JPEG) compressed data format structure generated from color multilevel image data input to an image processing device;
- a Start Of Image (SOI) area which stores starting information indicating a start of an image;
- an application segment area where an application segment is inserted;
- a compressed image data storage unit which stores compressed image data;
- and
- an End Of Image (EOI) area which stores ending information indicating an end of the image;
- wherein the compressed image data storage area stores compressed color image data generated from the color multilevel image data, and the application segment area stores the compressed monochrome image data generated from the color multilevel image data.
