Change Log
----------

0.9.1.48c (August 19 2009)

Fixes:
[1] Spurious images in bulk trigger
[2] Variable image intensity in overlapped trigger mode



0.9.1.48b (July 10 2009)

Fixes:
[1] Fixed issue where black lines may appear in the image at increased camera temperature.
[2] Shutter changes when toggling trigger enable bit.
[3] Image corruption when switching video modes while async trigger is enabled.

Enhancements:
[1] Support for adjacent pixel clock correction.



0.9.0.48 (Jan 16 2009)

Fixes:
[1] Occasional bright images when in trigger mode 14
[2] Mono cameras only output 12 bpp in Y16.  This change adds raw16 as a supported pixel type in format 7for mono sensors. When the camera is placed in this mode it will output raw / unprocessed pixel data. 
[3] First triggered image too dark.
[4] Problem when setting upper and lower bounds of auto range registers to the same value.

Enhancements:
[1] Fixed: GRAS-50S5 - Support for 4x4 binning 612x512 @ 45fps.



0.9.0.47 (November 17 2008)

Enhancements:
[1] GRAS-50S5: Supports processing of full size images and at all pixel clock speeds
[2] GRAS-03K2: Supports trigger mode 14 (overlapped trigger) even when using its fastest video clocking. This should allow us to run at 200fps in an async trigger mode. 
[3] GRAS-20S4: Added improved intensity balancing 



0.9.1.46 (October 02 2008)
[1] Internal test build.



0.9.1.44 (August 22 2008)

Enhancements:
[1] Gras-50s5 now supports a 4x4 binning mode: fmt7_mode7 provides a quarter size image.
[2] Gras-03k2 now supports higher speed ROI images. It should now be faster than the DX. This fix may not work that well on some of the earlier cameras.
[3] All cameras now have the fix for the issue regarding corrupt data while using narrow ROIs.
[4] Gras-20s4 should now saturate in colour binning modes.  It should also have more uniform response across pixel clocks [see bug 6234].



0.9.1.40 (June 30 2008)

Enhancements:
[1] Enabled gamma correction of bayer8 pixels for GRAS-20S4 cameras.



0.9.1.32 (September 2007)

Fixes:
[1] Strobe pattern should work properly with software trigger

Enhancements:
[1] Implemented Min_Bayer_Gain CSR [1A1Ch]
[2] Only support sending dual iso packets at S800.
[3] GRAS-03S3 only: The camera will have some fine resolution shutter units even in binning modes
[4] GRAS-03S3 only: changed the "zero" gain value by -2.25dB [-64 gain steps]
[5] The strobe start event when the camera is in bulk trigger is now shutter start



0.9.1.30 (9 Jan 2008)

Fixes:
[1] Absolute shutter value spontaneously changes

Enhancements:
[1] Added support for a cross-talk correction between adjacent pixels for balancing (50S5C)
[2] Improvements to dual tap CCD balancing (50S5)



0.9.1.28 (12 Jul 2007)

Fixes:
[1] Dynamically changing ROI position results in image corruption
[2] Corrupt images in various Format 7 modes (50S5)
[3] Wrong Bayer tile pattern (50S5)
[4] Bayer pattern apparent in monochrome image (50S5)
[5] Poor image quality in Format 7 Mode 3 Mono8 (50S5)
[6] Moving vertical bars of color at 60MHz (50S5)
[7] Vertical line noise with some fmt7_mode0 configs
[8] Odd balancing effect at max gain (50S5)

Enhancements:
[1] Enhancement: Format 7 resize inquiry register 0x1AC8



0.9.0.26 (03 Jul 2007)

Fixes:
[1] Stops sending images after data flash access

Enhancements:
[1] Minor CCD tuning at 50MHz (50S5)



0.9.0.24 (25 Jun 2007)

Fixes:
[1] Frame rate in fmt7_mode1 mono8 is slower than expected (20S4)



0.9.0.22 (07 Jun 2007)

Fixes:
[1] Saturated areas are pink with 66MHz clock rate and low gain (20S4)

Enhancements:
[1] Remove non-Format_7 1600x1200 30fps frame rate (20S4)
[2] General GRAS-50S5 balancing improvements



0.9.0.20 (29 May 2007)

Fixes:
[1] Problem writing greater than 256K to 512K flash 

Enhancements:
[1] Frame buffer / image retransmit capability
[2] Reduce the maximum GRAS-20S4 gain to 16dB at the fastest pixel clocks [50MHz and above]



0.9.0.18 (15 May 2007)

Enhancements:
[1] Enhancement: Initial full frame buffer support
[2] Enhancement: Bi-color red/green LED support
