Claims20
An image processing apparatus, which performs a predetermined process on image data inputted along a main scanning direction and a sub-scanning direction perpendicular to the main scanning direction, comprising:
- first recognizing means for recognizing an image data of an end portion in the main scanning direction from a first predetermined number of the image data inputted along the main scanning direction;
- first correction means for deleting the image of the end portion recognized by the first recognizing means;
- second recognizing means for recognizing an image data of an end portion in the sub-scanning direction, from a second predetermined number of the image data inputted along the sub-scanning direction;
- and
- second correction means for deleting the image of the end portion recognized by the second recognizing means.
An image processing method, which performs a predetermined process on image data inputted along a main scanning direction and a sub-scanning direction perpendicular to the main scanning direction, comprising:
- a first recognizing step of recognizing an image data of an end portion in the main scanning direction from a predetermined number of the image data inputted along the main scanning direction;
- a first correction step of deleting the image of the end portion recognized by the first recognizing means;
- a second recognizing step of recognizing an image data of an end portion in the sub-scanning direction, from the predetermined number of the image data inputted along the sub-scanning direction;
- and
- a second correction step for deleting the image of the end portion recognized by the second recognizing step.
