Abstract

A control apparatus of an image filing system has an image memory device for storing high and low resolution image information for displaying an image on each page of a manuscript with high and low resolutions, respectively; a plurality of page buffers for temporarily storing the image information; an image search display device for reading the low resolution image information out of an optical disk to search the image and storing the read low resolution image information to one of the page buffers, and displaying the image on a screen by the low resolution image information; and an image processing device for reading the high resolution image information out of the optical disk to perform various kinds of designated image processing and storing the read high resolution image information to another one of the page buffers, and performing the various kinds of image processing with respect to the high resolution image information. The control apparatus further has a functional device for performing in parallel the various kinds of image processing with respect to the high resolution image information and the image display on the screen by the low resolution image information.

Claims

1. A control apparatus of an image filing system, comprising:

an image memory means for storing high resolution image information and low resolution image information in order to display a manuscript image of each page of a manuscript at low resolution and to print the manuscript image at high resolution;

a plurality of page buffers for temporarily storing the high resolution image information and the low resolution image information;

an image display means including a monitor, for reading the low resolution image information out of said image memory means, storing the read low resolution image information at one of said page buffers and displaying the manuscript image on a monitor on the basis of the stored low resolution image information;

an image processing means for reading the high resolution image information out of said image memory means, storing the read high resolution image information at another one of said page buffers and printing the manuscript image by a printing means on the basis of the stored high resolution image information;

a functional means for performing in parallel image display and image processing in such a manner that a first manuscript image is printed on the basis of a first high resolution image information stored at said page buffers while a second high resolution image information relating to a second manuscript image is stored at said page buffers, and a first low resolution image information stored in said image memory means relating to the second manuscript image is further read out to said page buffers and the second manuscript image is displayed on said monitor; and

a control means for controlling operations of said image memory means, said plurality of page buffers, said image display means, said image processing means and said functional means so as to cause said functional means to perform in parallel the image display and the image processing.

2. A control apparatus of an image filing system according to claim 1, in which said image processing means is adapted to data-extend and temporarily store at said another one of said page buffers the high resolution image information of each page of the manuscript.

3. A control apparatus of an image filing system according to claim 2, in which said image display means is adapted to data-compress and temporarily store at said one of said page buffers the low resolution image information.

4. A control apparatus of an image filing system according to claim 1, in which said image display means is adapted to thin out the low resolution image information.

5. A control apparatus of an image filing system according to claim 1, in which said image display means is adapted to change the data of the low resolution image information to data which is different in amount and corresponds to a manuscript image which can be displayed in real size on said monitor.
