New features and changes introduced in this version are:

Interactive ROI Tool

You can now select a region of interest (ROI) interactively while previewing your image data in the Image Acquisition Tool. The interactive tool lets you select and adjust a region of interest in the Preview Window while previewing. The drag-and-draw mechanism makes setting a region of interest much easier and faster.

For more information on this feature see Setting a Region of Interest Interactively in the Image Acquisition Toolbox documentation.

Additional Export Locations

You can export data that has been acquired in memory in the Image Acquisition Tool to a MAT-file or the MATLAB Workspace. In R2008b you can export to additional locations, including Image Tool and Image File for single-frame acquisitions, and Movie Player for multiple-frame acquisitions. These three options are provided by the Image Processing Toolbox™ software.

For more information on exporting data, see Exporting Data in the Image Acquisition Toolbox documentation.

New .avi File Save Option

In the Image Acquisition Tool, when you log an acquisition to disk, it is saved as an .avi file. In version R2008b an option was added to automatically increment the .avi file names. This is useful if you want to acquire multiple videos of one or more subjects. For example, a lab technician may want to acquire 10 seconds of video on a group of five different cultures and save them for later analysis. The technician may want resulting file names such as sample_0001.avi, sample_0002.avi, etc. This new option allows for automatic file name incrementing like this example.

For more information on logging data to .avi files, see Disk Logging in the Image Acquisition Toolbox documentation.

Improved Device Properties Tab

The Device Properties tab in the Image Acquisition Tool is used to set device-specific properties. In R2008b, the Device Properties pane has been improved. Most properties now feature a slider for setting the value, in addition to the capability of setting it manually. You can adjust the slider while previewing and see the results dynamically.

Property help was also added in the pane. Right-click a property name and select What's This? to see the help on that property.

For more information on setting device properties, see Setting Device-Specific Parameters in the Image Acquisition Toolbox documentation.

Preview Window Has 16-Bit Data Support

The Image Acquisition Toolbox Preview window and the Preview window that is built into the Image Acquisition Tool now support the display of up to 16-bit image data. The Preview window was designed to only show 8-bit data, but many cameras return 10-, 12-, 14-, or 16-bit data. The Preview window display now supports these higher bit-depth cameras.

Additional DALSA Hardware Support

Support has been added for the following new DALSA^® hardware:

X64 Xcelera-CL PX4 Dual™
X64 Xcelera-CL PX4 Full™
X64-CL-Express™
PC2-Comp™ Express

The Image Processing Toolbox Software Required to Use the Image Acquisition Toolbox Software

The Image Acquisition Toolbox product, including the Image Acquisition Tool, now requires you to have a license for the Image Processing Toolbox product starting in R2008b.

If you already have the Image Processing Toolbox product, you do not need to do anything.

If you do not have the Image Processing Toolbox product, the Image Acquisition Toolbox software R2008a and earlier will continue to work. If you want to use R2008b or future releases, and you have a current active license for the Image Acquisition Toolbox software, you can download the Image Processing Toolbox product for free. New customers will need to purchase both products to use the Image Acquisition Toolbox product.

If you have any questions, please contact MathWorks customer service.

New Trigger Configuration Names for Some DALSA Sapera Boards

In previous releases of the Sapera adaptor, some boards had trigger sources trigger3, trigger4, and trigger5. In the current release of the Sapera driver, these trigger sources have actual names. Note that the sources trigger1 and trigger2 correspond with actual inputs on the board, while trigger sources 3, 4, and 5 do not.

Compatibility Considerations

The only customers that will be impacted are those that were using previously supported boards and the improper trigger source names. These boards are:

x64-CL iPro
x64-LVDS
x64 Full
x64 Dual

For these boards, in R2008b the trigger sources will use their actual names:

trigger3 – boardSync
trigger4 – toBoardSync
trigger5 – cameraControlToBoardSync

In R2008b if you attempt to set the trigger source to trigger3-5, you will receive a warning and the new trigger source name will be used. In R2009a, you will receive an error message, and in R2009b, you will receive the standard invalid trigger source error message.

Note that the old names will only show up in the warning, and will not show up in the output from triggerinfo or triggerconfig.

Loading saved objects is not an issue. Potentially an object saved in R2008a would not load in R2009a or beyond once the warning message is turned into an error. However, trigger configurations of videoinput objects are not saved. Therefore trigger configurations which will be invalid in R2009a will not be saved for objects in R2008a or earlier.
