Abstract
Abstract An image processing system has a reader with an image sensor, a retention memory unit connected to the reader, and a printer connected to the retention memory unit. The reader, the retention memory unit and the printer have a hierarchical control structure in order named. The retention memory unit has dynamic RAMs each of which stores image data of at least one page. The image data entered at the reader is selectively stored in the RAMs. When an operator wishes to form the image represented by the image data on a plurality of copying sheets, the corresponding original is scanned only once before copying on the first copy sheet. For the second and subsequent sheets, the image signal is selectively read out from the RAMs. The signal readout is inhibited by selectors and gates in the retention memory unit in response to logical states of corresponding flags at the end of copying.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
169 words
An image processing system comprising: input means for inputting an image signal; storage means for storing the image signal of at least one page input by said input means; readout means for reading out the image signal from said storage means; and control means for controlling reading out of the image signal from said storage means by said readout means, said control means being operable to control said readout means in either a first mode, in which the image signal is read out from said storage means at an arbitrary time after completion of storage of the image signal in said storage means, or a second mode, in which the image signal is read out from said storage means at a specified time after completion of storage of the image signal in said storage means, wherein said control means inhibits the image signal read out from said storage means in the second mode from being read out from said storage means by said readout means in the first mode.
Claim 2
Dependent Claim
169 words
An image processing system comprising: input means for inputting an image signal; storage means for storing the image signal of at least one page input by said input means; readout means for reading out the image signal from said storage means; and control means for controlling reading out of the image signal from said storage means by said readout means, said control means being operable to control said readout means in either a first mode, in which the image signal is read out from said storage means at an arbitrary time after completion of storage of the image signal in said storage means, or a second mode, in which the image signal is read out from said storage means at a specified time after completion of storage of the image signal in said storage means, wherein said control means inhibits the image signal read out from said storage means in the second mode from being read out from said storage means by said readout means in the first mode.
Claim 3
Dependent Claim
29 words
A system according to claim 1, wherein said input means comprises reading means for photoelectrically reading an original image and generating the image signal to represent the original image.
Claim 4
Dependent Claim
25 words
A system according to claim 1, further comprising setting means for setting a mode for reading out of the image signal by said readout means.
Claim 5
Dependent Claim
30 words
A system according to claim 1, further comprising recording means for recording an image on a recording medium in accordance with the image signal read out from said storage means.
Claim 6
Dependent Claim
23 words
A system according to claim 1, further comprising instruction means for instructing a reading out of the image signal from said storage means.
Claim 7
Dependent Claim
40 words
A system according to claim 1, wherein, in the second mode, said control means causes said readout means to read out the image signal from said storage means following completion of storage of the image signal in said storage means.
Claim 8
Dependent Claim
155 words
An image processing system comprising: input means for inputting an image signal; storage means for storing the image signal of at least one frame; readout means for reading out the image signal from said storage means; and synthesizing means for synthesizing the image signal entered from said input means and the image signal read out from said storage means, wherein said readout means is operable in either a first mode, in which the image signal is read out from said storage means at an arbitrary time, or a second mode, in which the image signal is read out from said storage means at a specified time, and wherein the image signal read out from said storage means in the second mode is inhibited from being read out from said storage means by said readout means in the first mode and being synthesized by said synthesizing means with the image signal entered from said input means.
Claim 9
Dependent Claim
155 words
An image processing system comprising: input means for inputting an image signal; storage means for storing the image signal of at least one frame; readout means for reading out the image signal from said storage means; and synthesizing means for synthesizing the image signal entered from said input means and the image signal read out from said storage means, wherein said readout means is operable in either a first mode, in which the image signal is read out from said storage means at an arbitrary time, or a second mode, in which the image signal is read out from said storage means at a specified time, and wherein the image signal read out from said storage means in the second mode is inhibited from being read out from said storage means by said readout means in the first mode and being synthesized by said synthesizing means with the image signal entered from said input means.
Claim 10
Dependent Claim
19 words
A system according to claim 7, wherein said storage means stores the image signal entered from said input means.
Claim 11
Dependent Claim
30 words
A system according to claim 7, wherein said input means comprises image reading means for photoelectrically reading an original image and generating the image signal to represent the original image.
Claim 12
Dependent Claim
28 words
A system according to claim 7, further comprising recording means for recording an image on a recording medium in accordance with a synthesized image from said synthesizing means.
Claim 13
Dependent Claim
29 words
A system according to claim 7, wherein said readout means is operable to read out the image signal from said storage in synchronism with entry of the image signal.
Claim 14
Dependent Claim
19 words
A system according to claim 7, further comprising instruction means for instructing a synthesizing operation by said synthesizing means.
Claim 15
Dependent Claim
35 words
A system according to claim 7, wherein, in the second mode, said readout means reads out the image signal from said storage means following completion of storage of the image signal in said storage means.
