♦Ball-Point Pen Mode

When an image made with a pencil or ball-point pen is scanned, the light reflected from the pencil lead or ink is not uniform. As a result, part of the image may be missing. If the [Ball-Point Pen] checkbox is checked, filtering is applied to offset the bright area in the document and compensate for disconnected or faint lines.

♦OCR Smoothing/ Background Removal

The OCR smoothing is the function to make smooth the notched part of line-drawing, and the Background Removal is the function to remove the uneven background.

These functions are enabled when it is selected.

For further information, please refer to the User’s guide attached to the IPC board since the function to be operated is different by the type of IPC.

At IPC-3/3D, [Noise Removal] and [OCR smoothing/ Background removal] is enabled exclusively.

This option uses an algorithm that removes particles from 2 x 2 to 5 x 5 dot matrixes. The size of one dot depends on the resolution setting, and is equivalent to 1/400 inch for 400 dpi. Particles are distinguished from the text by whether they are connected to other dots within the specified number of pixels.
