DELTA SDK Release Notes

v1.3.0

Released 2026-09-29

[Viewer Improvements]

  1. Added automatic camera detection and improved device disconnection handling to prevent the Viewer from becoming unresponsive when a camera is disconnected.

  2. Reorganized the right-hand panel to display settings specific to Live Streaming Mode and File Player Mode.

  3. Consolidated status and error notifications into toast messages displayed in the lower-right corner of the Viewer.

  4. Standardized the Viewer appearance to Dark Theme and removed the theme selection option.

  5. Added Packet Analyzer under the Debug menu for raw data inspection:

  6. Live Capture Mode: Captures and analyzes the specified number of frames while the camera is streaming.

  7. File Mode: Analyzes an existing .dvs file up to the specified frame limit, with a maximum of 2,000,000 frames.

  8. Updated the Options menu:

  9. Auto-apply recommended setting on camera select: Automatically applies recommended settings for the selected camera.

  10. Advanced USB Settings: Provides access to USB timeout, buffer count, and transfer size settings. The default values are recommended for normal use.

  11. Added drag-and-drop support for opening .dvs files in File Player Mode, along with elapsed and total playback time displays.

  12. Added USB connection speed information for DELTA10 cameras to assist with checking cable and USB port connections.

[Recording Improvements]

  1. Improved image and video recording finalization to ensure buffered frames are processed when recording is stopped. Saving may continue briefly after recording stops.

  2. Improved handling of slow storage devices. If the recording buffer reaches its capacity, recording stops and frames already buffered are saved.

[Bug Fixes]

  1. Fixed an issue affecting DELTA01 timestamp accuracy and recorded duration.

[File Compatibility]

  1. Updated the .dvs file format to support accurate device-specific timing. DELTA01 and DELTA10 files recorded with version 1.3.0 should be opened with SDK/Viewer 1.3.0, as earlier versions may not support these files.

  2. Reading .dvs files saved in the previous format remains supported.

v1.2.2

  1. Fixed an issue where the Viewer device list continuously refreshed on Linux.
  2. Fixed a bug that prevented the Windows installer (Delta_Setup_WIN64.exe) from installing the camera driver.
  3. Fixed a bug that prevented MatSave from working on Windows.
  4. Updated the Viewer UI, including the device refresh button and status indicator.
