Image Functions *4 In IPC-3D, a seven step parameter is used like as with the Simplified Dynamic Threshold but the algorithm is different. *5 In IPC-3D, if both Simplified DTC and Image Emphasis are specified, the Simplified DTC algorithm is activated. At that time, both the Simplified Dynamic Threshold and Image Emphasis High/Mid/Low parameters are in affect. *6 In IPC-3D, if Automatic Separation is specified, then Simplified Dynamic Threshold and Image Emphasis/Smoothing are ignored.
3.2 Basic image functions o: Can be specified. x: Cannot be specified. ▲: Enabled if automatic separation is specified, otherwise ignored. : Can be specified but not enabled. *1 If DTC is specified, IPC can be specified but not enabled. *2 The image is not guaranteed. *3 Can be specified but not enabled if Image Emphasis is also specified. *4 Can be specified but not enabled if Outline Extraction is also specified. *5 Not recommended because the compression is inefficient. 3.

Image Functions (2) Page End Detection [A.4.11 READ command / Detected paper length] This function cuts the reading operation when page end is detected, even if all of the window length L (sub-scanning length) is not read yet. This function is useful to reduce the image data and increase the throughput. When Page End Detection is set ON, the image data which is out of the page end is deleted.
3.2 Basic image functions 3.2.3 Binary reading [A.4.7 SET WINDOW command / Image Composition = X’00’] Following three parameters are available when binarizing the image. The 256 levels of the density at each pixel is processed by Contrast and binarized by Threshold. When the White level following is se ON, the white level of the CCD output follows the background of the document. So this is useful for line art drawing but not for photograph. Table 3.
Image Functions 3.2.4 Halftone reading [A.4.7 SET WINDOW command/Image Composition = X’01’] This scanner supports two types of halftone image, that is Dither and Error Diffusion. (1) Dither [A.4.7 SET WINDOW command / Halftone type = X’01’] This is a way of producing halftone images with white and black pixels. The scanned image is processed by the unit of group of pixels. At first a reference table called “dither matrix” is specified.
3.2 Basic image functions Table 3.
Image Functions Grayscale reading 3.2.5 [A.4.7 SET WINDOW command / Image Composition = X’02’] Eight bit Grayscale reading is available. Following image processing functions can be specified for grayscale reading. (See Table 3.2) • X,Y resolution (XR,YR) • Main window offset (ULX, ULY) • Main window size (W, L) • Contrast • Black and White reverse NOTICE: The throughput of the grayscale reading may 1/2 slower than binary reading. NOTICE: The output resolution is limited as shown in Table 2.
3.3 Optional image function 3.3 Optional image function Image functions in this section are available when IPC-2D or IPC3D option is installed. The name of command and data in [ ] beneath the section title show the location for the reference in Appendix A. 3.3.1 DTC mode function (Auto I mode) [A.4.7 SET WINDOW command / DTC selection = X’40’] This mode is designed to scan for better image quality to provide OCR (Optical Character Reader).
Image Functions (1) Pre-filter [A.4.7 SET WINDOW command / DTC mode] The pre-filter performs filtering before processing the Dynamic Threshold. Ordinary and Ballpoint Pen are selectable in Pre-filter. Table 3.7 Parameter of Pre-filter Name of parameter value Effect with IPC-2D Ordinary X’00’ Linear gamma curve High Contrast X’10’ Makes low contrast Image clear (for dark background document) Effect with IPC-3D Default Linear gamma curve X’00’ Use Ordinary basically.
3.3 Optional image function (2) Gradation [A.4.7 SET WINDOW command / DTC mode] Gradation specifies the gamma curve correction before processing Dynamic Threshold. When scanning news papers or old documents which background is dark, it is desirable that the gamma curve has coarse steps in the lighter side and fine steps in the darker side. This is called High Contrast gamma curve.
Image Functions (3) Dynamic Threshold Curve [A.4.7 SET WINDOW command/DTC mode] For the Dynamic Threshold function, the threshold is changed with the average optical density of a small area (e.g. 5 x 5 pixel area). Relation between the threshold and maximum density is formed as a curve when the threshold is expressed in the Y-axis and the maximum density in the X-axis. This curve is called “threshold curve”. This function allows a customer to select a threshold curve.
3.3 Optional image function (4) Equal to White [A.4.7 SET WINDOW command/DTC mode] Equal to White specifies the result of binaizing when the value of a pixel equals the threshold. The default is Equal to White OFF. The effect of this parameter is slight but, if the scanned image text is bold, set to Equal to White. If the scanned Image text is too narrow or lost, set to Equal to Black (Equal to White OFF). Table 3.
Image Functions (5) Noise Removal [A.4.7 SET WINDOW command / DTC mode] Noise Removal reduces the isolated spot noise after Dynamic Threshold. If the image is noisy. Turn on the Noise Removal and set the granularity to the size of noise to be removed. The parameter of Noise Removal is as follows. Table 3.
3.3 Optional image function (6) Smoothing [A.4.7 SET WINDOW command / DTC mode] Smoothing in DTC mode is done after binarizing. This function smooths a slant line or curve by eliminating jagged edges on the line. An irregularly protruding portions are removed and an Irregularly cut portions are filled In. The parameters of smoothing are as follows. The Image Smoothing do no smoothing. If an image scanned in low resolution and the outline is jagged, specify the OCR smoothing.
Image Functions 3.3.2 IPC mode (Auto II mode) [A.4.7 SET WINDOW command/DTC SELECTION = X’00’ or X’80’] In this mode, the algorithm of dynamic threshold is deferent between IPC-2D and IPC-3D. This mode is recommended for general electric filing purpose.
3.3 Optional image function b) IPC2 like Simplified Dynamic Threshold IPC-3D supports IPC-2 like Simplified Dynamic Threshold for compatibility purpose. When both Image Emphasis and Simplified Dynamic Threshold are set, it is regarded as IPD-2 like Simplified Dynamic Threshold. In this case, IPC-3D Sensitivity parameters in Simplified Dynamic Threshold are used as the Variance Rate, and Image Emphasis parameters are used for emphasis. The IPC-2 like Simplified Dynamic Threshold increases resolution.
Image Functions (1) Image Emphasis [A.4.7 SET WINDOW command / Image Emphasis] Image Emphasis performs filtering to emphasize image edges or to smooth (IPC-2D) or remove background noise (IPC-3D). If text edges are not clear or faint, turn on the Image Emphasis. Three levels of Image Emphasis, High/Mid/Low, are available. As a side effect, Image Emphasis also emphasizes the noise. It is better to set Image Emphasis higher to obtain good image, until the noise is not perceptible.
3.
Image Functions (2) Outline Extraction [A.4.7 SET WINDOW command / Outline extraction] The Outline function extracts the edges from images. This function is rarely used. It may be used in DTP for image effects or image sensing. Table 3.14 parameter of Outline Extraction 3-24 Parameter Value Effect OFF X’00’ Outline Extraction is disabled. ON X’80’ Outline Extraction is enabled.
3.3 Optional image function (3) Automatic Separation [A.4.7 SET WINDOW command / Automatic Separation] With this feature, the scanner automatically recognize the text areas and photo areas on the document. For the areas that are recognized as text areas, scanned data are processed as pure binary with no halftone algorithm (fixed threshold or automatic binarization). For areas that are recognized as photo areas, scanned data are processed with a halftone algorithm (Dither or Error Diffusion). Table 3.
Image Functions (4) Mirror image [A.4.7 SET WINDOW command / Mirror image] A scanned image is turned over symmetrically in the main scan direction, generating a mirrored reflection of an image. Table 3.
3.3 Optional image function (5) Black and White reverse [A.4.7 SET WINDOW command/RIF (reverse image format)] Black and White Reverse turns the black part of the image white and white part of the image black. This effect is similar to the negative/positive image from camera. Table 3.17 Parameter of Black and White Reverse 3.3.3 Parameter Value Effect OFF X’00’ Black and White Reverse OFF ON X’80’ Black and White Reverse ON Default OFF Sub-Window [A.4.
Image Functions 3.3.4 Zooming [A.4.7 SET WINDOW command/X,Y resolution] Zooming is the function to enlarge or reduce the image from 400 dpi. X and Y independent variable resolutions are supported. This zooming is processed in grayscale, so smooth and non-distorted images can be obtained even when halftone is applied. NOTICE: Resolution is converted by an electrical method.

A.2 SCSI Bus A.2 SCSI Bus A.2.1 System configuration (1) System configuration The SCSI bus connects up to eight SCSI devices, each linked with a daisy chain. The both ends of the daisy chain require a terminator. Each SCSI device operates as an initiator or a target, so that a series of operations are performed between a pair of initiator and target pair.
Scanner Interface A.2.2 Bus signals Initiator Signal name Type of signal Target Data DB0 DB1 DB2 DB3 DB4 DB5 DB6 DB7 (Data Bus n) DBP (Data Bus Parity) Control signals BSY (Busy) SEL (Select) RST (Reset) C/ D (Control/Data) I/ O Eight data-bit signals, plus a parity-bit signal that form a DATA BUS. DB(7) is the most significant bit and has the highest priority during the ARBITRATION phase. Bit number, significance, and priority decrease downward to DB(0).
A.2 SCSI Bus A.2.3 Bus signal drive conditions SCSI devices drive signals of the SCSI bus. The types of SCSI devices are summarized in the following table, showing the signals that they can drive for each operating phase of the interface. There are two kinds of signal driving methods, OR tied and NON-OR tied, as shown in Table A.2. During an interface operating sequence, the BSY signal could be driven simultaneously by two or more SCSI units when the data bus is in the ARBITRATION or RESELECTION phase.
Scanner Interface Table A.3 Method of driving the interface signal OR connection NON-OR connection False No signal is driven by any SCSI device. Signal status is made false by the termination resistor circuits. True A SCSI device drives the signal true. The signal is driven false by a certain SCSI device (initiator or target), or is not driven by any SCSI device. A.
A.3 Bus Phases Table A.4 Signal delay times definition (1/2) No. Item Time Definition 1 Arbitration delay 2.4 µs The minimum time an SCSI device shall wait from asserting BSY for arbitration until the DATA BUS can be examined to see if arbitration has been won. There is no maximum time. 2 Assertion period 90 ns The minimum time that a target shall assert REQ (or REQB) while using synchronous data transfers.
Scanner Interface Table A.4 Signal delay times definition (2/2) No. Item 10 Disconnection delay 200 µs The minimum time that a target shall wait after releasing BSY before participating in an ARBITRATION phase when honoring a DISCONNECT message from the initiator 11 Hold time 45 ns The minimum time added between the assertion of REQ (or REQB) or ACK (or ACKB) and the changing of the data lines to provide hold time in the initiator or target while using synchronous data transfers.
A.3 Bus Phases A.3.1 BUS FREE phase The BUS FREE phase is used to indicate that no SCSI device is actively using the SCSI bus, and that it is available. SCSI devices shall detect the BUS FREE phase after the SEL and BSY signals are both false for at least a bus settle delay. SCSI devices shall release all SCSI bus signals within a bus clear delay after the BSY and SEL signals become continuously false for a bus settle delay. bus settle delay bus clear delay BSY SEL others BUS FREE phase A.3.

A.3 Bus Phases A.3.3 SELECTION phase The SELECTION phase allows an initiator to select a target for the purpose of initiating some target function (e.g., READ or WRITE command). During the SELECTION phase the I/O signal is negated so that this phase can be distinguished from the RESELECTION phase. 1) The SCSI device that won the arbitration has both the BSY and SEL signals asserted and has delayed at least a bus clear delay plus a bus settle delay before ending the ARBITRATION phase.
Scanner Interface A.3.4 RESELECTION phase RESELECTION is an optional phase that allows a target to reconnect to an initiator for the purpose of continuing some operation that was previously started by the initiator but was suspended by the target (i.e., the target disconnected by allowing a BUS FREE phase to occur before the operation was complete).
A.3 Bus Phases A.3.5 INFORMATION TRANSFER phases Note: The COMMAND, DATA, STATUS, and MESSAGE phases are all grouped together as the information transfer phases because they are all used to transfer data or control information via the DATA BUS. The actual content of the information is beyond the scope of this section. The C/D, I/O, and MSG signals are used to distinguish between the different information transfer phases (see Table A.5).
Scanner Interface INFORMATION INFORMATION TRANSFER phase bus settle delay Min. 0ns TRANSFER phase bus settle delay BSY SEL C/D, MSG, I/O REQ ACK DB The INFORMATION TRANSFER phases use one or more REQ/ACK handshakes to control the information transfer. Each REQ/ACK handshake allows the transfer of one byte of information. During the INFORMATION TRANSFER phases the BSY signal shall remain true and the SEL signal shall remain false.
A.3 Bus Phases After the ACK signal is false, the target may continue the transfer by driving the DB (7-0, P) signals and asserting the REQ signal, as previously described. bus settle delay deskew delay + cable skew delay deskew delay + cable skew delay BSY SEL C/D, MSG I/O REQ ACK DB b. Asynchronous transfer from initiator to target If the I/O signal is false (transfer to the target), the target shall request information by asserting the REQ signal.
Scanner Interface bus settle delay deskew delay + cable skew delay deskew delay + cable skew delay BSY SEL C/D, MSG I/O REQ ACK DB (2) Synchronous information transfer Synchronous data transfer is optional and is only used data phases. It shall be used in a data phase if a synchronous data transfer agreement has been established (see 4.6.2. (13)). The agreement specifies the REQ/ACK offset and the minimum transfer period.
A.3 Bus Phases a. Synchronous transfer from target to initiator If the I/O signal is true (transfer to the initiator), the target shall first drive the DB (70, P) signals to their desired values, wait at least one deskew delay plus one cable skew delay, then assert the REQ signals. The DB (7-0, P) signals shall be held valid for a minimum of one deskew delay plus one cable skew delay plus one hold time after the assertion of the REQ signal.

A.4 Commands (2) Window list data: DATA OUT phase (Initiator to Target) The window list data parameter specifies the window ID for scanner reading. The scanner supports the following. a. Simplex reading specification Transfer length = 1 Window list data Byte 0 b.
Scanner Interface A.5 Status: STATUS phase (target → initiator) Each time a command is terminated, the target moves into the STATUS phase and returns a status byte to the initiator to report the completion of the command. Status byte 7 Byte 0 6 5 (Reserved) 4 3 2 Status byte code 1 0 (Reserved) The status supported by this scanner are summarized in the following table. Code 000000 Status of unit GOOD • 000001 00100 The command has successfully terminated.
A.6 Messages When a target is released from the BUSY status, it will not issue a notification of the release. Therefore, the initiator needs to check the status of units periodically and needs to issue the command again. A.6 Messages This section describes the detection of an ATN signal and explains the types of messages supported by this scanner. A.6.1 ATN detection The following table summarizes the timing at which this scanner detects an ATN signal. Phase *1 A.6.

A.6 Messages When this scanner receives the INITIATOR DETECTED ERROR message, this scanner enters the MESSAGE IN phase and sends the RESTORE POINTERS message to the initiator. Then this scanner returns to the original phase and makes a retry. After issuing the RESTORE POINTERS message, this scanner takes action as shown in the following table.
Scanner Interface Upon receiving the MESSAGE REJECT message, this scanner takes action as shown in the following table. Message rejected (5) Action COMMAND COMPLETE Moves to the BUS FREE phase. (It is not assumed as an error.) MESSAGE REJECT Responds the CHECK CONDITION status DISCONNECT The command execution is continued with connecting the SCSI bus (without disconnecting). SAVE DATA POINTER The command execution is continued with connecting the SCSI bus (without disconnecting).
A.6 Messages BUS DEVICE RESET (X’0C’) : MESSAGE OUT phase (initiator → target) (7) This message addresses any initiators that are operating, or waiting for operation, on the target. The message initializes those initiators by resetting their input/ output operations. The BUS DEVICE RESET message is transferred in the asynchronous mode. This scanner generates the UNIT ATTENTION condition to all initiators. After being initialized, the initiators move to the BUS FREE phase.
Scanner Interface The link will not be disconnected if bit 6 in the IDENTIFY message is 0. Also, it will not be disconnected if the IDENTIFY message is not issued in a given command sequence. For disconnect to occur therefore, bit 6 in the IDENTIFY message must be set to 1. When performing the disconnection during data transfer, this scanner sends the SAVE DATA POINTER message before sending the DISCONNECT message so that the data pointer is saved.
A.6 Messages SAVE DATA POINTER (X’02’) : MESSAGE IN phase (target → initiator) (10) This message is sent from the target to the initiator in order to save the current data pointer. The initiator saves the current data pointer value into the saved pointer for the logical unit currently connected.
Scanner Interface ASYNCHRONOUS DATA TRANSFER REQUEST (SDTR) message exchange shall be initiated by an SCSI device whenever a previously arranged data transfer agreement may have become invalid. The agreement becomes invalid after any condition which may leave the data transfer agreement in an indeterminate state such as: a) after a hard reset condition; b) after a BUS DEVICE RESET message and; c) after a power cycle.

A.7 Command Sequence Notes: 1. If the requested transfer volume is not equal to the actual data volume, this scanner informs the initiator that the requested transfer amount is abnormal. This is done as the scanner returns the status 00001 (CHECK CONDITION) and creates the following sense data: • ILI = 1 • INFORMATION = requested transfer amount (TL) - actual data amount This status is usually sent to the last READ command of the sequence.
