Abstract
An image information processing system is provided with an image reading unit, a memory unit, a signal compression unit and a transmission unit mutually connected through a bus line, for image formation inside the system or information transfer to or from an external system.
Claims19
An image information processing system comprising:
- read means connected to a bus line for reading an original image by photoelectric conversion and supplying image information representing the original image to said bus line;
- memory means connected to said bus line for storing the image information received from said read means through said bus line;
- compression means connected to said bus line for compressing the image information received from said read means through said bus line;
- communication means for transmitting the image information compressed by said compression means to an external apparatus and for receiving start command data from said external apparatus;
- and
- control means for controlling the operation of said read means, said memory means, said compression means, and said communication means, wherein said control means causes said read means to read the original image in response to start command data from said external apparatus and causes the communication means to transmit the compressed image information to said external apparatus.

An image information processing system comprising:
- communication means for receiving image information subjected to a compression process and command data from an external apparatus;
- expansion means connected to a bus line for expanding the compressed image information received by said communication means and for supplying image information to said bus line;
- memory means connected to said bus line for storing the image information received from said expansion means through said bus line;
- image information means connected to said bus line for forming an image in accordance with the image information received from said memory means through said bus line;
- and
- control means for controlling the operation of said communication means, said expansion means, said memory means, and said image formation means, wherein said control means causes said memory means to repeatedly read out the same image information in accordance with said command data from said external apparatus instructing the performance of a plurality of image formation operations so as to effect image formation of the same image information a plurality of times.
3 more elements
An image information processing system comprising:
- read means for reading an original image and supplying image information representing the original image;
- image forming means for forming an image in accordance with the image information supplied by said read means;
- communication means for transmitting the image information supplied by said read means to an external apparatus and for receiving start command data from said external apparatus;
- selection means for selecting one of a first and second mode, wherein said image forming means forms an image in accordance with the image information in the first mode and said communication means transmits the image information to said external apparatus in the second mode;
- input means for inputting an instruction;
- and
- control means for controlling the operation of said read means, said image forming means, and said communication means in accordance with one of the first and second modes selected by said selection means, wherein said control means initiates said operations in response to the instruction from said input means in the first mode and wherein said control means initiates said operations in response to start command data from said external apparatus in the second mode.
