GigE uEye SE Optimized With version 3.40, the GigE uEye SE cameras run considerably faster than before. By doubling the possible data rate, the maximum frame rate could be increased significantly. For the 5 Megapixel models UI-5480-M and -C the frame rate increases from 6 to 14 fps. In order to update GigE uEye SE cameras that are already in use you must once upload the firmware manually. This can be done in the uEye Camera Manager.
Firmware Upload for GigE uEye SE Since driver version 3.30, GigE uEye SE cameras support manual firmware upload via the uEye Camera Manager. From version 3.40 on the upload is performed automatically. The camera firmware will be updated when firmware and driver versions do not match.
GigE uEye CCD Cameras Optimized Hardware trigger signals are now recognized considerably faster. The sensor starts image capture within 75 µs after a trigger signal occurred.
Support for DHCP It is now possible to connect GigE uEye cameras to a Windows PC in a DHCP network. In this case the PC’s IP address is assigned by the DHCP server. The camera’s IP address must be assigned using the uEye Camera Manager. Under Linux it is required to use persistent IP addresses for both the PC and the camera.
DirectDraw Becomes Direct3D An increasing number of graphics cards discontinue DirectDraw support in favor of Direct3D, especially since the introduction of PCIexpress cards.
DirectX - This Windows-only package of programming interfaces for multimedia focused applications relies on 3D functions. 2D functions provided by DirectDraw are no longer maintained. The new Direct3D mode replaces the DirectDraw mode entirely. Upcoming uEye drivers will still provide support for DirectDraw functions but they are not used anymore in uEye demo software.
Semi-Transparent Overlay With Direct3D it is possible to draw image overlays. Additionally, alpha-blending can be enabled for semi-transparent overlay display and BMP files can be loaded into the overlay area.
Improved Display of Live Images Direct3D allows synchronization of the image display with the monitor's image rendering. The image is displayed upon the monitor's next VSYNC signal. This prevents horizontally moving display artifacts known from some DirectDraw modes. You can choose different synchronization types: automatic, user defined or no synchronization. Multi-monitor operation is also supported. On graphics cards with low performance, displaying camera images with high resolution (5 or 10 Megapixel) might cause unexpected effects on the image start.
System Requirement DirectX 9.0c The new Direct3D functions require an up-to-date version of DirectX 9.0c Runtime to be installed on the system. The currently installed version is shown in the uEye Camera Manager. Linux does not provide any support for DirectX functions.
New Sample Program “uEyeDirectRenderer” The new sample program with source code in C++ demonstrates the uEye driver’s Direct3D functionality, e.g. semi-transparent overlay.
Crosshair Sample program On customer request we added a sample program displaying a crosshair overlay on top of the camera’s live image. This program is based on the new Direct3D functions. You can change the crosshair color and enable an additional circle around the crosshair center. All settings are saved on exit. Exposure and contrast can be controlled manually or via the uEye auto controls.
DirectShow Version 3.40 improves compatibility of the uEye DirectShow interface. Generic applications based on DirectShow (such as the Windows Movie Maker) can now directly access uEye cameras. Some non-standard features from previous versions of the uEye DirectShow interface had to be removed for compatibility reasons. In some cases a previously supported feature might no longer be working. Downgrading the DirectShow interface version will restore these features.
Timestamp and Image Info A new function provides additional information on the images you take. The function returns a timestamp indicating the time of image capture, the states of the camera I/Os, and the internal buffer status at that point in time. The buffer status shows the usage level of camera memory and thus how fast the camera can transfer images to the PC. For GigE uEye cameras, the timestamp is recorded by the camera itself with an accuracy of 100 ns. For USB uEye cameras the timestamp returns the time when image data transfer to the PC was completed. You can also retrieve a timestamp which is synchronized with the PC's system time.
Sensor Auto Controls for UI-122x / 522x Models The sensors MT9V032 of the UI-122x / 522x uEye models provides internal auto exposure (AES) and auto gain (AGC) controls. With these cameras, you can now choose between software-based and sensor-based auto controls. The sensor’s auto controls react faster, but also behave differently from the existing API controls.
New Camera Models Driver 3.40 includes support of the new GigE uEye RE series and of 149x / 549x cameras with 10 Megapixel sensor.
HALCON Interface Extended The following features have been implemented:
Cognex VisionPro and CVL Interface uEye software package 3.40 includes a new Cognex AIK interface which supports both USB and GigE uEye cameras. Multiple cameras and different types can be used simultaneously. The interface is part of the standard setup and available on the download section of our website. |
