Abstract

An image information processing system has reader for photoelectrically reading an image of an original and producing an image data. The image data produced by said reader is selectively encoded in accordance with the area designation.

Claims

1. An image information system comprising:

reading means for photoelectrically reading an image of an original and producing image data;

means for designating arbitrary area of the image of the original; and

means for transmitting the image data produced by said reading means, said transmitting means including means for compressing the image data produced by said reading means,

said transmitting means being operable to transmit image data of either a first area designated by said designating means or a second area other than said first area upon compression of the image data of said either area by said compressing means, and to transmit image data of another area on a non-compression basis.

2. An image information processing system according to claim 1, further comprising memory means for storing therein the image data corresponding to one picture frame produced by said reading means and wherein said transmitting means transmits the image data read out from said memory means.

3. An image information processing system according to claim 1, wherein said transmitting means includes a first signal path for transmission of the image data produced by said reading means through said compressing means and a second signal path for transmission of said image data without passing through said compressing means.

4. An image information processing system according to claim 1, wherein said transmitting transmits the image data to an external apparatus.

5. An image information processing system comprising:

means for producing image data representative of an image of an original;

means for transmitting image data to be supplied to an external apparatus;

first supplying means for compressing image data df a first area of the original produced by said producing means and supplying the comressed image data to said transmitting means; and

second supplying means for supplying to said transmitting means image data of a second area of the original different from said first area produced by said producing means without compression thereof.

6. An image information processing system according to claim 5, further comprising designating means for designating the first area and the second area of the original.

7. An image information processing system according to claim 5, wherein said producing means comprises means for photoelectrically reading the image of the original and generating the image data.

8. An image information processing system according to claim 5, wherien said producing means comprises means for storing therein the image data corresponding to one picture frame.

9. An image information processing system comprising:

reading means for photoelectrically reading an image of an original and producing image data;

means for designating an arbitrary area of the image of the original; and

means for transmitting the image data produced by said reading means, said transmitting means including means for reducing resolution of the image data produced by said reading means,

said transmitting means being operable to transmit image data of either a first area designated by said designating means or a second area other than said first area upon reduction of resolution of data of said either area by said reducing means, and to transmit image data of another area without reducing resolution thereof.

10. An image information processing system according to claim 9, wherein said reducing means is capable of reducing the resolution of the image data at a plurality of different rates.

11. An image information processing system according to claim 9, wherein said transmitting means includes memory means for storing one picture frame of image data to be transmitted.

12. An image information processing system according to claim 9, wherein said transmitting transmits the image data to an external apparatus.

13. An image information processing system comprising:

means for producing image data representative of an image of an original;

means for transmitting image data to be supplied to an external apparatus;

first supply means for reducing resolution of the image data of a first area of the original produced by said producing means and supplying the image data reduced in resolution to said transmitting means; and

second supply means for supplying image data of a second area of the original different from said first area produced by said producing means without reduction of resolution thereof.

14. An image information processing system according to claim 13, further comprising designating means for designating the first area and the second area of the original.

15. An image information processing system according to claim 13, wherein said producing means comprises means for photoelectrically reading the image of the original and generating the image data.

16. An image information processing system according to claim 13, wherein-said producing means comprising means for storing therein the image data corresponding to one picture frame.
