Features Added Since 4.2

The following features have been added to uScope Navigator since the release of v4.2.

  • Predictive Fast Stack Focus Method
    Added a new focus method that combines features of the Predictive focus and Fast Stack focus methods.
  • Added Configuration Settings for Auto-Focus
    Added the ability for end-users to alter the default settings used for auto-focus when browsing a slide and when starting a slide scan.
  • Camera Speed Controls
    Added the ability to reduce the camera speed for slower PCs and Laptops. This should allow the uScope Navigator software to work with PCs and laptops with slow USB connections.
  • Firmware Updater
    Added a firmware upgrade facility for uScopes with older firmware. This enables users to upgrade the firmware in their uScope hardware.
  • Calibration Data Stored in uScope
    Calibration data are now stored in the internal memory of the uScope. Calibration data stored on the USB flash drive are no longer required when moving the uScope to a new computer.
  • Auto-Calibration for New Installations
    Users are now prompted to auto-calibrate the overview and objective cameras on initial installation of the uScope on a new computer. This should help improve initial image quality.
  • SVS (Tiled TIFF) Output
    Added SVS (Tiled TIFF) file output. This new output file is compatible with whole slide image viewers from other third parties.
  • HD/SD Camera Mode Selection
    Added the ability to select either HD (high-definition) or SD (standard definition) camera mode when browsing a slide. This will allow users to compare camera modes without having to load the device settings tab and changing camera settings.
  • Improved Viewer Load Speed
    Improved the speed at which images are loaded in the field set viewer. This will reduce user wait time when loading large scanned images.
  • Improved Browse Mode Controls
    Moved browse mode controls to a slide-in panel when viewing the image from the objective camera. This allows additional controls to be added without consuming more screen real-estate. This panel includes a new ability to limit browse image to 200% digital magnification.
  • Added Overview Image Preview for Filters
    Added the ability to use the current overview image when editing an overview filter.
  • Modified Level Clipping Filter
    Modified the Level Clipping filter to allow clipping to pure white or to the selected white level. In most cases, clipping to the selected white level produces more pleasing images. The Deep Zoom image viewer has been updated with the ability to clip to pure white or the selected white level as well.
  • Improved HD Scan Speed
    Improved the speed of HD (high-definition) scans by up to 45% for initial/predictive focus and up to 15% for exhaustive focus.
  • Added Background Image Stitching
    Added the ability to combine fields for the deep zoom image while scanning. This option is enabled in the Application Settings Screen under Deep Zoom Preferences.
  • Improved Deep Zoom Responsiveness
    Improved responsiveness and performance of creating deep zoom images.
  • Added More Information to Scan Dialog
    Added additional information to the scan dialog.
  • Added Device Info Tab
    Added a Device Info Tab to the Device Settings Dialog to show device-specific information including Device ID, Internal Temperature, and the assigned Name of the uScope.
  • Improved USB Connect/Disconnect Performance
    USB device connect/disconnect now works in situations when you plug or unplug a uScope while uScope navigator is running.
  • Updated Driver and Application Code Signing
    Updated the certificate used to sign drivers and application program files. This eliminates the untrusted driver dialog that appeared on some versions of Windows. The latest release of Windows 10 is also supported.
  • Labelled Objective Tab
    Improved the Device Settings Screen to show Objective Tabs using the Objective Description.
  • Added Underlap Setting for Scans
    Added the ability to underlap fields when scanning a region of interest. This feature is useful when you need to guarantee that there is no overlap between adjacent fields in a scan.
  • Added Scan/Deep Zoom User Buttons
    Added two user buttons to the Job Manager specific to scan or deep zoom selection.
  • Added Saved Images Folder
    Added a saved images folder where images saved in browse mode are stored.
  • Improved User Button Editor
    Improved User Button creation in Application Settings.
  • Improved Predictive Focus Method Performance
    Altered predictive focus to capture prediction points bidirectionally. In addition, adjacent prediction points are used to set the focus range for subsequent prediction points. This has the effect of better tracking focus points that have a very high deviation across the scanned region.
