Note :  1. The Pcam Driver has been re-structured since version 4.0.0.0. The regisrty entries 
	"CCDType" and "CDSType", which configure driver for different devices, have been replaced by 
	SensorType.  Before install the driver, please check if the "SensorType" values in pcam812v.inf 
	matchs with the sensor type of your device.

        SensorType:  	1 – Toshiba VGA CMOS sensor
			2 – HP VGA CMOS sensor
			3 – ICMedia VGA CMOS sensor
			4 – Pixart VGA CMOS sensor
			5 – TASC VGA CMOS sensor

	SensorVerion	Currently, only TASC VGA CMOS sensor uses this flag.
			0 - Divio's demo board TASC 5130B.
			1 - TASC's demo board TASC 5130B_PCAM_DIV812 TASC 00-12


	2. Audio interface doesn't work after first time installation on a fresh new Win98. This
	is due to some issue with Microsoft DirectX. Please update the latest version of DirectX 
        runtime library, which can be free downloaded from http://www.microsoft.com/directx. 
        Alternatively, you may just disconnect your camera from PC and reconnect it. It will work.
	
	
Difference from Version 4.0.0.0
1. Assigned registers by name.
2. Removed DF_MapReg sub-routine.
3. Updated initial audio register setting.
4. Added 176x144 5, 7.5, 10, 12.5, and 15 raw data feature.
5. Reprogramed audio registers after reset Go bit.
6. Fixed the bending problem which appears when changing stream frame rate. The reason is
   that the shutter isn't changed with the frame rate.
7. Fixed Toshiba AGC is always minimun in Home or Office bug.
8. Fixed Toshiba shift right bug.

Difference from version 4.0.0.2
1. Refined video for Toshiba 5043, Agilent 2020 solutions.
2. Add audio/composite installer for windows 2000. 
3. Correct uninstaller unable to remove composite inf file problem.
4. Fixed 'green' screen (from dark to bright enviroment, especially in 640x480) problem. 
   Changed DF_CalculateRGBGain() as device or sensor dependent. 
5. Adjusted threshold for AGC, frame rate, and shutter.
6. Updated gamma table for Toshiba sensors (based on NW820).
7. Whenever run time changing frame rate, Cmc_sel and ClkDiv_vga work as a pair, the transition
   time is not smooth. Divid frame rate as two groups: 30, 25, 15, and 12.5 as first one; 12.5,
   10, 7.5, and 5 as second one. These effect both frame rate and shutter.
8. Fixed bug for VGA 5 frame per second display.

Difference from version 4.0.0.3
1. Removed software reset at initial time.
2. Fixed HP2020 320x240, 30fps 'freeze' bug.
3. Don't do software reset at power down time.
4. Adjusted Toshiba5043 NonFlickerShutter and AGC threshold.
5. Adjusted HP2020 AGC threshold.
6. Adjusted AGC min. and max. boundaries.
7. Used 'PC VGA A/V Camera' as NW812 product name.
8. Add NW812 register for divpcam.exe.

Difference from version 4.0.0.4
1. Removed 'Pcam812a.inf', 'Pcam812c.inf', and 'Lower812.sys' after installation.
2. Removed 'Lower812.sys' from '\SYSTEM32\DRIVER\' during uninstallation.

Difference from Version 4.0.0.5
1. Change DR_RegIndex() to point to temp buffer defined in the RegTable for undefined register.

Difference from Version 4.0.0.6
1. Added MaxAGC and MinAGC back to the Registry.

Difference from Version 4.0.0.7
1. Fixed Property Index bug.
2. Fixed WDM Video Capture Suite (Iris) test failure bug - too big valid range.
3. Add ICMedia CMOS sensor for NW812.

Difference from Version 4.0.0.8
1. Change the AE, AWB sequence: First do AE, after AE stable, do AWB.
2. Fixed WHQL Driver Verifier Test bug.
3. Fixed HCT 10.0 test failure - AssertUrbExpectedLength.
4. Added SkipFrame flag to swab colors on fly (NW802, SensorType 4, SensorVersion 2).
5. Porting Pixart 202B CMOS sensor.

Difference from Version 4.0.0.9
1. Corrected I2C error flag read bit.
2. Implemented OB reading for IC Media CMOS sensor.
3. Modified to support different Vendor ID while remove device using setupapi for Windows 2000/XP.

Difference from Version 4.0.0.10
1. Added TASC 5130B CMOS sensor for NW812.
2. Fixed Pixart unmatched Frame rate/shutter table issue.

Difference from Version 4.0.0.11
1. Adjusted AE and AWB.
2. Changed ADClock as system clock for TASC. Software used ClkDiv_vga(101Ah) only for selecting clock.
3. Added SensorVersion 1 for TAS5130B_PCAM_DIV812 TASC 00-12 demo board.
4. Implemented temp flags: if AE not change, don't update agc, shutter, and frame rate.

Difference from Version 4.0.0.12
Improve AWB for all solution

Difference from version 4.0.0.15
1. Improved the reliability of USB Audio function.
2. Remove the frame rate limitation for Pixart 202B Sensor.

Difference from version 4.0.0.16
1. Provide centralized message handling on WM_Close messages and
fix the failure to release handles after transfer picture issue.
2. Added the hardware snapshot event trigger mechanism on user mode passed event.  (Requested from NEC/MCI)
3. Add in WIA functionality only on Windows XP.
