New features and changes introduced in this version are:

New Image Acquisition Toolbox™ Simulink® Block

A new Simulink® block, the From Video Device block, allows Simulink users to acquire image and video data streams from image acquisition devices such as cameras and frame grabbers in order to incorporate the image data into a Simulink model. The new block also offers the ability to configure and preview the acquisition directly from Simulink.

Compatibility Considerations

The former Image Acquisition Toolbox™ block, the Video Input block, is obsolete. If you have models that use the Video Input block, you should change them to use the new From Video Device block, which offers additional functionality and features.

New Hardware Support

Improved DCAM Driver

The Image Acquisition Toolbox software now uses an improved DCAM adaptor, which uses version 6.4.2 of the CMU DCAM driver. The new driver supports 1394B firewire and DCAM 1.3.1. It also supports new frame rates of 120 and 240 frames per second.

Corrected Spelling of Two QImaging Device-Specific Property Values

The following QImaging device-specific property values have changed to correct the spelling:

Compatibility Considerations

Fan Speed Property

Some QImaging video input source objects have a fan speed property if the camera supports it. If they do, one of the possible values is ¾ speed. This property value was misspelled as ThreeQuater instead of ThreeQuarter (when the QImaging adaptor was introduced in the Image Acquisition Toolbox software Version 1.9, Release 2006a). The change allows the correct spelling to work instead of causing an error.

VIDEOINPUT objects: When loaded from MAT files, any misspelling will be silently corrected. You could notice the value is different if you inspect the FanSpeed property. Misspellings saved in R2006a/R2006b would load seamlessly in R2007a (backward compatible). Corrected spellings saved in R2007a, however, would error (not load) in R2006a/R2006b (forward incompatible).

SET: The misspelling will be obsoleted over several releases. In R2007a both spellings will be supported (backward compatible) but the misspelling will generate a warning. In the next significant release (IAT v2.1+1), the warning will be changed to an error that suggests correct spelling. In the following significant release (IAT v2.1+2), the error will become the standard incorrect property value response. Corrections written in R2007a would error in R2006a/R2006b (forward incompatible).

GET: Will return the correctly spelled value, even if set is called with the misspelling.

Readout Speed Property

Most/all QImaging video input source objects have a readout speed property. If they do, one of the possible values is 2.5 MHz. This property value was misspelled as 2M5 instead of 2.5M (when the QImaging adaptor was introduced in the Image Acquisition Toolbox software Version 1.9, Release 2006a). The change will allow the correct spelling to work instead of erroring.

VIDEOINPUT objects: When loaded from MAT files, any misspelling will be silently corrected. You could notice the value is different if you inspect the Readout property. Misspellings saved in R2006a/R2006b would load seamlessly in R2007a (backward compatible). Corrected spellings saved in R2007a, however, would error (not load) in R2006a/R2006b (forward incompatible).

SET: The misspelling will be obsoleted over several releases. In R2007a both spellings will be supported (backward compatible) but the misspelling will generate a warning. In the next significant release (IAT v2.1+1), the warning will be changed to an error that suggests correct spelling. In the following significant release (IAT v2.1+2), the error will become the standard incorrect property value response. Corrections written in R2007a would error in R2006a/R2006b (forward incompatible).

GET: Will return the correctly spelled value, even if set is called with the misspelling.
