Chapter 1: Introduction

Super-Mini-Size is the first color CIS flat-bed scanner introduced by Artec, we would like to develop the smallest flat-bed scanner to keep our ability of competition in world market. The traditional optical system of flat-bed scanner is using the color CIS and the color CIS is much smaller than traditional mirror box, so we will choice color CIS for our optical system in super mini-size flat-bed scanner.

1.1 General Description

Super mini-size is a flat-bed type color scanner which user put one paper each time on the scan platform and use software button to trigger scan. The scanning width is 8.5 inches, length is 11.7 inches. It also will not support transparency scan because the color CIS using led light source. The scanner can supported many scanning modes which is programmed via Parallel Port. This product can provide better image after software shading. Also the image quality should be good enough especially in resolution for OCR intensive users.

1.3 SoftWare Interface & User Interface

Since sheet-fed scanner will target home market, the software interface and user interface should provide ease of use and friendly interface. In software, One Click and Go will be the only thing that user will often do no matter she/he want to Scan , Copy , Print , or even Fax (Keep at lease 20 numbers that user often dial). In driver UI, any key word or setting should not let user to think and confuse, the ordinary user can understand every setting she/he want to do without ask experts. In HardWare UI, putting paper in(in Sheet-Fed mode) or press button(in Hand-Held mode) is the only thing she/he will do in order to scan. Automatic trigger scan and automatic stop scan will ne a must.

SoftWare Interface Requirement:

1) Scan

2) Print

3) Copy

4) Fax(combined with fax/modem card)

5) Image file management

6) OCR

7) Business Card arrangement

HardWare Interface Requirement

1) Paper in Sensor (Used to detect when user place paper then trigger scan)

2) Paper to Scan Line Sensor(Used to calculate the start scan line and when paper is end to stop scan)

3) Hand-Held Start Button(Used to start/stop scan when in hand-held mode)

4) CIS module Attached/Detached sensor(Used to decide whether user want sheet-fed mode or hand-held mode

Chapter 2: Electronics Design Specification

The electronics design of this system will cover interface, register setting, and image quality. Also the specification should cover future Flat-Bed application. Also since the sheet-fed should consider user s feeling when using this system, any design that will be finalized should be tested under extensive user s feeling.

2.1 Interface Protocal

Cobra interface with host system(PC) using P1284 Protocal, but exclude ECP mode. Also the

Negociation method do not follow the Protocal but using our own sequence to wake-up the system.

Please refer to the P1284 specification for more detail.

2.2 Command Timing

Please refer to the P1284 specification

2.3 Artec Private Wake-up Sequence

The system has one sequence to wake-up by the software from passthrough mode, describe as

follows.

D7-D4 6 C F 2 1

D3

Using rising-edge of D3 to sense the nibble data(formed by D7-D4), if the sequence is 6CF21

then the system will go into scanner mode. If any nibble data is wrong then the Checker will go

back to idle mode to re-trace this sequence. The 4 control lines(nInit, nStrobe, nSelectIn, nAutoFd)

should always be in HIGH state for correct wake-up sequence or the Checker will be reset to

idle mode. Go back to passthrough mode will need software to program one bit.

2.4 Register Description

will be described.

2.9 Calibration Method

Every Scanner need some method to correct the imperfectness of Electro-Opto Device, this section

describe how we do it. Also Color CIS s image performance is worse then CCD s, our system need

some more complicated method to do it.

2.6.10 Sheet-Fed Mode

Inside the accessory, our system has one Calibration Card which include some Uniform

Bright Area , Uniform Black Area , and Uniform Gary Area . The use of it is

described belows.

Uniform Bright Area: Since the CIS s LED has large deviation in brightness, we need

some method to let the driver to decide the Turn-On time for each LED(R,G,B). The

software use this area to adjust the brightness for each LED before doing any Dark &

White Calibration. After this the Turn-On time is decided and save to the .INI file.

Uniform Dark Area: Since the CIS s Dark Pixel Uniformity is very bad then CCD, we

need adjust the output of every pixel when LED is off, before we do White Calibration.

Uniform Gray Area: Since the CIS s PRNU is also very bad, we need to correct this by

Gray Calibration.

After we do all the calibration, the data should be saved to some .INI file in order to let

the scanned image looks good.

Important Notes: Before any scanning, the driver should check this file, if not present then

the driver should pop-up one diag-box to inform user she/he need to do it again. Also the

date of this file should be maintain, every three months, the driver should inform the user

to do it again if the image do not look good in the default setting.

2.6.11 Flat-Bed Mode

In the flat bed mode, since the calibration paper is hided inside the engine. It do not have any

chance to dirt it, we should built this paper inside it instead of using calibration chart.

The Reference Paper should include Uniform Bright Area , Uniform Black Area , and

Uniform Gray Area . All the calibration method is the same as above.
