Release notes

Scorpion camera drivers for HVGrab cameras.

1.0.4.46, 12oct2023, MVS 4.1

  • Image compression support for all modes, by using MVS conversion to BGR for all modes except Mono8

  • Calling Scorpion CB directly from within camera CB, intermediate buffer is eliminated

  • New parameter - MVS internal buffer count; default is 3

1.0.4.45, 5oct2023, MVS 4.1

  • Support for compressed image mode (when camera provides feature). Currently supported only for RGB8 mode.

  • Support all formats in non-compressed mode

  • GevPersistentSubnetMask/GevPersistentIPAddress/GevPersistentDefaultGateway parameters are readonly in the driver. Use MVS IP tools for network configuration

  • GevMACAddress and GevMCDA printed in HEX

1.0.4.44, 28sep2023, MVS 4.1

  • Replaced part of now obsolete API functions:

    • MV_CC_ConvertPixelType replaced by MV_CC_ConvertPixelTypeEx

    • MV_CC_Get(Set)IntValue replaced by MV_CC_Get(Set)IntValueEx

    • MV_CC_Get(Set)PixelFormat replaced by generic MV_CC_SetEnumValue

    • MV_CC_TriggerSoftwareExecute replaced by generic MV_CC_SetCommandValue

    • MV_CC_GetBalanceWhiteAuto replaced by generic MV_CC_GetEnumValue

    • MV_CC_Get(Set)BalanceRatioRed(Green/Blue) replaced by generic MV_CC_SetEnumValue (the selector) and MV_CC_Get(Set)IntValueEx

    • MV_XML_UpdateNodeFeature replaced by generic MV_CC_SetEnumValueByString

  • Manual BalanceRatioRed(Green/Blue) parameters now created whenever BalanceRatio selector is encountered, instead of BalanceColorTemperatureMode, which is not always present

1.0.4.43, 25sep2023, MVS 4.1

  • rebuilt against new MVS version (4.1)

1.0.4.42, 26oct2022, MVS 3.4.3 Important upgrade for PTP protocol

  • CU camera support - includes all cameras that provide (only) Bayer encoded stream

  • Changed method of internal conversion of grabbed images for Scorpion

  • New ForceColorMode parameter in General section

    • required to be set for Bayer color cameras

    • otherwise, ‘auto’ mode is sufficient

  • New parameters related to Bayer image conversion - BayerGamma, BayerCvtQuality and BayerMatrix

1.0.4.41, 26oct2022, MVS 3.4.3 Important upgrade for PTP protocol

  • PTP - Precision Time Protocol

    • Action support

    • Sync mutliple camera using PTP

    • Update User Guide

  • Frame counters and timestamps from camera

  • Image buffer is cleared after sending to Scorpion

  • Userguide updated, new sections added

1.0.4.40, 31mar2022, MVS 3.4.0 Support of camera AcquisitionMode: SingleFrame - New

  • New property SyncContinousMode (General section)

    • will synchronize Scorpion continous with AcquisitionMode

    • Set SyncContinousMode to True to enable

      • default value is False

    • Purpose is to avoid ContinousMode when running SingleFrame or SW Trigger

      • will stop the continous flow of images

  • if AcquisitionMode is in SingleFrame - assuming SyncContinousMode = True

    • Scorpion Grab (snapshot) will issue AcquisitionStart automatically

    • This avoids having to issue AcquisitionStart - for each image to be grabbed in SingleFrame mode

  • Camera commands are now exposed. Command is issued by setProperty(cmdname, 1)

  • Gui update:

    • double-click on enumerated parameter name cycles to the next value from the list (the same as in bool parameters)

1.0.4.39, 15mar2022, MVS 3.4.0

  • StartGrab issued like in pre-38 versions

1.0.4.38, 10mar2022, MVS 3.4.0
