Image forming system

Claim 2

An image forming system comprising: means for producing an image signal representing an original image; means for inputting a magnification or reduction scale for magnifying or reducing the image; first processing means for processing the image signal in accordance with the magnification or reduction scale so as to reproduce a magnified or reduced image; second processing means for processing the image signal so as to reproduce a halftone image; means for reproducing an image on a material in accordance with the image signal processed by said first and second processing means; and means for controlling the processing operation of said second processing means in accordance with the magnification or reduction operation of said first processing means.

Claim 3

An image forming system according to claim 1, wherein said producing means includes a sensor array.

Claim 4

An image forming system according to claim 1, wherein said reproducing means reproduces the image line by line.

Claim 5

An image forming system according to claim 1, wherein said first processing means converts an amount of the image signal in accordance with the magnification or reduction scale.

Claim 6

An image forming system according to claim 1, wherein said second processing means dither-processes the image signal.

Claim 7

An image forming system comprising: means for producing an image signal representing an original image; first input means for inputting data representing a desired area of the original image; second input means for inputting a magnification or reduction scale for magnifying or reducing the image; means for processing the image signal of the desired area in accordance with the magnification or reduction scale so as to reproduce a magnified or reduced image of the desired area; means for reproducing an image on a material in accordance with the image signal processed by said processing means; and means for controlling a reproduction position of the magnified or reduced image of the desired area on the material, in accordance with both the data representing the desired area and the magnification or reduction scale.

Claim 8

An image forming system comprising: means for producing an image signal representing an original image; first input means for inputting data representing a desired area of the original image; second input means for inputting a magnification or reduction scale for magnifying or reducing the image; means for processing the image signal of the desired area in accordance with the magnification or reduction scale so as to reproduce a magnified or reduced image of the desired area; means for reproducing an image on a material in accordance with the image signal processed by said processing means; and means for controlling a reproduction position of the magnified or reduced image of the desired area on the material, in accordance with both the data representing the desired area and the magnification or reduction scale.

Claim 9

An image forming system according to claim 6, wherein said producing means includes a sensor array.

Claim 10

An image forming system according to claim 6, wherein said reproducing means reproduces the image line by line.

Claim 11

An image forming system according to claim 6, further comprising means for extracting a signal from the image signal produced by said producing means, the extracted signal representing an image of the desired area.

Claim 12

An image forming system according to claim 6, wherein when data indicating the reproduction position is manually set, said control means controls the reproduction position of the magnified or reproduced image of the desired area, regardless of the data representing the desired area and the magnification or reduction scale, in accordance with the data indicating the reproduction position.
