2.3 Optional Circuit Feature

The following option is provided for this scanner:

f Image processing circuit ¬ (M3097E0191)

For the details, refer to Subsection 2.3.1.

2.3.1 Image processing circuit ¬ (IPC ¬)

This option has the dynamic threshold function and image processing function.

2.3.1.1 Dynamic threshold function

The main purpose of this function is to read handwritten characters.

Handwritten character recognition preprocessing invalues specifying required
values for threshold curve setting, smoothing mode, and filtering mode.

Noise removal reduces noise often found in images after dynamic threshold
processing.

The dynamic threshold circuit is selected when control register #1 bit 4 is set to 1 or
DENSITY is set to AUTO 1 on the operator panel.

Threshold curve setting, smoothing mode, filtering mode, and noise removal are all
dynamic threshold circuit (DTC) functions.

(1) Threshold curve setting

The contrast level of the dynamic threshold circuit can be changed with setting 3
bits (8 levels).

(2) Smoothing mode

The convex portion of the segment is removed and the concave portion is filled up to
smooth the segment.

(3) Filtering mode

(a) Ball>point pen mode

This mode is used when this scanner is used as the input device of OCR system.
When using writing materials caused inter>ommission, e.g. ball>point pen, the
density of the omission portion is increased according to the density of
surrounding portion to get the picture does not have inter>omission.

2 $ 4 50FH5037E>02

(b) Normal mode

This mode is used when using writing materials other than above.

(4) Noise removal

Among black>dots in the binary picture code, the black>dot for the noise is changed
to white>dot.

6.1 Basic Command/Response Sequence

Data is transmitted between the host computer and the image scanner in the form
of commands and responses. Figure 6.1 shows the basic command/response
sequence. In Figure 6.1, ™Other than ACK∫ means a parity, flaming, overrun, or
count error.

Notes:

1. Abnormal reception means that a parity error, flaming error, overrun error, or
count error has occurred.

2. Command or response transmission is retried only twice.

3. Upon reception, a command or response is checked for transmission errors. When
the check result has no problem, ACK is returned immediately to the originating
source. When the check result has problem, data other than ACK is returned after
all data has been received.

4. The originating source of the command/response monitors the response from the
receiving side. ACK indicates that command/response transmission is completed.
Data other than ACK causes the command/response to be transmitted again. The
transmission is retried only twice. After that, the scanner waits for a new
command.

5. Response data such as ACK must be returned to the originating source within 0.5
second.

6. The interval between words in the data steam must be no more than 10 ms.

*1 This function is valid for image processing circuit (IPC ¬) option.

When the IPC ¬ option is installed and these bits indicate 1xxxx, the scanner
applies the DTC function, and the function of the image control register and
subwindow control register are not operated.

*2 The scanning speed of ADF (sheets/min) in Linedrawing mode is different from

that of Photograph mode. See Appendix B for more information.

*3 When the control registor #19, bit 0 is ©0π, 8 typs density are sellectable by the

control registor #1, bit 3 to 0.

And when the control registor #19, bit 0 is ©1π, 256 typs density are sellectable
by the control registor #20.

separation mode. However halftone processing (dither or error diffusion) for
photo area follows control register #19, and the dither pattern follows
control register #2.

*2 The subwindow control register is valid when the subwindow is valid.

*3 When automatic separation specification is based on operator panel, the bit

7 of image control register #2 and the bit 3 of image control register #3
must be set to ©0π.

X©00π is set when the power is turned on or when the initial state is specified by the

pattern. When the power to the scanner is turned off or when the scanner is
reset, registration must be done again. When a pattern is built in, registration
need not be done again.

Pattern data format

1 byte data corresponds to data for 1 dot.

1

For dither pattern

X`00' to X`3F' should be sent as dither pattern.

2

For overlay pattern

X`00' or X`FF' should be sent
When the data is X`FF', the data of the dot is changed to white.
When the data is X`00', the data of the dot is not changed.

Transfer the dither and overlay patterns in the order shown below.
