## Abstract

An image processing apparatus includes an input device for image data, a discriminating device for discriminating a type of an image represented by the image data, a setting device for setting a discrimination standard of the discriminating device, and a display for displaying a condition of the setting device.

## Claims

### Claim 1

An image processing method comprising:
an input step of inputting image data;
a discriminating step of discriminating a type of an image represented by the image data;
a setting step of setting a discrimination standard of said discriminating step; and
a display step of displaying a condition in said setting step.

### Claim 2 (depends on 1)

A method according to claim 1, wherein said discriminating step discriminates a line image portion of the image based on the image data.

### Claim 3 (depends on 2)

A method according to claim 2, wherein said setting step sets a parameter for discriminating, in said discriminating step, the line image portion of the image.

### Claim 4 (depends on 1)

A method according to claim 1, wherein the image data input in said input step includes a plurality of color components.

### Claim 5 (depends on 4)

A method according to claim 4, further comprising a step of detecting a black portion of the image based on the image data input in said input step.

### Claim 6 (depends on 5)

A method according to claim 5, further comprising a step of judging a black character portion of the image data input in said input step when the black portion of the image is detected in said detecting step.

### Claim 7 (depends on 6)

A method according to claim 6, further comprising a step of processing the image data input in said input step in accordance with a judging result of said judging step.

### Claim 8 (depends on 7)

A method according to claim 7, wherein said setting step controls an intensity of the process which is performed for the black character portion in said processing step.

### Claim 9 (depends on 1)

A method according to claim 1, wherein said setting step and said display step utilize a touch panel display.

### Claim 10

An image processing apparatus comprising:
input means for inputting image data;
discriminating means for discriminating a type of an image represented by the image data;
setting means for setting a discrimination standard of said discriminating means; and
display means for displaying a condition of said setting means.

### Claim 11 (depends on 10)

An apparatus according to claim 10, wherein said discriminating means discriminates a line image portion of the image based on the image data.

### Claim 12 (depends on 11)

An apparatus according to claim 11, wherein said setting means sets a parameter for discriminating the line image portion of the image by said discriminating means.

### Claim 13 (depends on 10)

An apparatus according to claim 10, wherein the image data input by said input means includes a plurality of color components.

### Claim 14 (depends on 13)

An apparatus according to claim 13, further comprising detecting means for detecting a black portion of the image data input by said input means.

### Claim 15 (depends on 14)

An apparatus according to claim 14, further comprising judging means for judging a black character portion of the image data input by said input means when said detecting means detects the black portion of the image.

### Claim 16 (depends on 15)

An apparatus according to claim 15, further comprising processing means for processing the image data input by said input means in accordance with a judging result of said judging means.

### Claim 17 (depends on 16)

An apparatus according to claim 16, wherein said setting means controls an intensity of the process which is performed for the black character portion by said processing means.

### Claim 18 (depends on 10)

An apparatus according to claim 10, wherein said setting means and said display means are composed of a touch panel display.
