Live View panel
Adjusting image settings
Once you have successfully gained access to your camera’s video feed through AnalystAssist’s Live View panel, you can make adjustments to the image in order to get it to match closer to what you see down the binoculars of your microscope.
To do this, click the Settings wheel icon at the top-left of the Live View panel to open the ‘Settings’ collapsible panel. Click the wheel icon again to close the panel.
Adjustments are made by holding your left mouse button on the blue dot and dragging the slider. Possible adjustments are:
Brightness - increase/decrease the intensity of the lighter areas of the image
Exposure - increase/decrease the intensity of the entire image
Saturation - increase/decrease the amount of colour in the image
RGB Channels - increase/decrease the red, green and blue levels of the image
Contrast - increase/decrease the intensity differential between bright and dark areas of the image
White Balance - increase/decrease the warmth of the image by changing the Kelvin value (higher values appear colder, lower values appear warmer).
Power Frequency - if your camera has this capability, this should be set to the frequency of your local electricity grid. It should auto-detect your local setting. (When incorrectly set, the unseen flickering of your microscope lamp conflicts with the flicker rate of the camera sensor causing a strobing/flickering effect on screen. Aligning both with the frequency of the local power grid resolves this issue.)
Frame rate - adjust the framerate that the camera feed is displayed at.
Please Note: Adjusting either the Power Frequency or the Frame rate will cause a ‘Restart Cam’ button to appear. Click this to properly induce your required changes.)
All Settings changes will be stored in your browser’s cache, until you do a hard refresh (Ctrl + F5) or you click the circular ‘reset’ icon at the top of the Settings panel
Rename images
Just like in the Appointment Blood Images panels, you can change the title of an image displayed under the image in a thumbnail.
To give images a more identifiable title, click on the title in any thumbnail to enter ‘edit mode’. Make any required changes and to save changes to the database, click the ‘Enter’ key on your keyboard. To exit without saving and revert to the previously saved title, click your ‘Escape’ key or click somewhere else on the screen. Duplicate image titles are not allowed.
View large versions of images & add Image Notes
Click any thumbnail to open the Image View panel - this displays a large version of the image.
Image Notes - Click the ‘Image Notes’ collapsible panel to open or close it. Add text in the panel and it will be saved automatically. These Notes can be viewed at any time in the Appointment Record by hovering your mouse cursor over the thumbnail, and can be included in Appointment Reports.
View the image full-size - click the ‘View full-sized image in new browser tab’ button to open a separate browser tab that displays the image full-size.
To close the Image View panel, click the ‘X’ button in the top right corner.
Recording video
It is possible to record up to 60 seconds of live feed in the Live View panel. Video footage is stored as a .mp4 file (or WebM for some browsers) which is added to the Downloads folder of the browser:
Click the ‘Record’ button to start the recording process. The button will switch to a red ‘Stop’ button with a timer.
To finish recording, click the red ‘Stop’ button (or it will happen automatically after 60 seconds).
The video file (with date/time nomenclature) will be added to the browser’s Download folder, where it can be played or renamed.
Capturing & managing images
Capture images
First of all, adjust the Zoom slider if necessary to change the size of image frame to be captured.
Next, click the ‘Capture’ button to store what is seen on screen. A thumbnail version of the image will be added to the top of the Stored Images panel to the right.
Please Note: Although thumbnails in the Blood Image panels of the Appointment Record are sorted alphabetically, in the Live View panel there is no sorting so the most recent captures are at the top of the Stored Images panel, until the Live View panel is closed.
Delete images
To permanently delete one or more images from the database, check the checkbox in the relevant thumbnail(s) and click the red trashcan. The Delete Confirmation dialog will display.
If you click the ‘Delete’ button in the Delete Confirmation dialog to confirm deletion, the image will be deleted from the Live View ‘Stored Images’ panel and also the Appointment Blood Images panel that you triggered the Live View panel from.
Click the ‘Cancel’ button or the ‘Escape’ key on your keyboard to close the Delete Confirmation dialog without deleting any images.
The Live View panel is accessed from Live & Dry Blood Images panels in Appointment Records, and is where AnalystAssist connects with your microsope camera and displays the camera feed. The Live View panel also enables you to capture the images that you see on screen, and insert them into the Appointment Record.
The panel is also accessible from the dashboard with the ‘Test Cam’ button. This option is for setting up your camera, and testing that AnalystAssist has access. It is possible to capture images in this mode, but they are saved directly to the Downloads folder of your browser.
It is also possible to save a video of the live feed (max 60 secs) in both versions. Video files are saved to the Downloads folder of your browser and NOT stored in the AnalystAssist database. Files are stored in .mp4 format (or WebM in certain browsers).
Please Note: For data compliance purposes, files saved to the Downloads folder of the browser are non-identifiable to Client/Patients and only include the date/time of capture in the file name.
Features include:
Collapsible Settings panel - allows you to adjust image settings such as brightness, contrast, or even the power frequency for your local electricity grid (to prevent flashing).
Main video image panel - this section displays the current live feed from the selected camera (as long as your browser has permission to access a camera).
Camera control panel - under the video image panel, this panel includes a drop-down selector to choose which camera feed is being used, a slider to zoom the image in and out, and the main ‘Capture’ button for taking a screenshot of the image displayed and ‘Record’ button for recording a video of the live feed.
Saved Images panel - this section shows the saved images for either the Live or Dry Blood Images panel of the current Appointment (depending on which panel was used to trigger the Live View panel). Thumbnails displayed here can be clicked to view a large version of the image or update the Image Notes. It is also possible to change image titles, and delete images from the database here (NB: Panel not displayed in ‘Test Cam’ mode).
The Live View panel can be closed at any point, by clicking the ‘Close’ button in the top-right corner. Doing so will automatically update the Appointment Record Blood Images panel that you used to trigger the Live View panel, with any changes to the image gallery and/or image names or notes (NB: Not with ‘Test Cam’ mode).
Please Note: Inactivity Timout is suspended when the Live View panel is open.
Connecting to your microscope camera
One of the first tasks needed when you start using AnalystAssist is to connect your microscope camera to your computer, and then make sure that AnalystAssist can access it.
There are 2 camera options that we will discuss here:
USB digital microscope camera connected to your computer
Canon DSLR camera using ‘Live View’ mode and connected via its USB port
USB Digital Microscope Camera
In this scenario, you will have a USB cable from the camera that should be plugged into a USB port on your computer. It may be advisable to go to the ‘Camera’ section of your Operating System’s Settings screen and make sure that the computer recognises it. There may be driver software that you need to install in order to make this happen.
Once your computer has recognised the camera:
Open AnalystAssist (ideally in a Chrome browser) and log in.
In the Dashboard, click the ‘Camera Test’ button to open the preview version of the Live View panel.
When the Live View panel opens, it will try to do so using your computer’s default camera choice. If this is the first time using this browser, a window should appear asking you to grant permission for the browser to access the camera.
Give the browser permission to access the camera. Wait a moment and the live feed from the camera should appear on screen. If it is dark, make sure that the microscope has a light source switched on, or alternatively pull the camera out of the microscope trinocular and let roon light enter the sensor - you should see blurred images on screen.
NB: If you still don’t see an image, open the ‘Camera’ drop-down selector at the bottom of the Live View panel, and make sure that the correct camera model is selected.
Mount a slide with a sample of something on the microscope, increase the illumination until you see an image on screen, and adjust the microscope focus apparatus until the image on screen is focused.
Canon DSLR camera
The process for connecting a Canon DSLR camera to AnalystAssist involves a few more steps. Before your computer can access a live feed from the camera, you need to do the following:
Go to https://www.canon.co.uk/cameras/eos-webcam-utility/ and download EOS Webcam Utility Pro for your operating system (Windows or Mac). This is a free piece of software from Canon that enables you to use your DSLR camera as a webcam.
Install the software package, giving any permission requested.
Connect your camera to a USB port on your computer using a suitable USB cable for your camera’s USB out port.
Switch the camera to ‘On’ at the main power switch on the camera body and turn the main dial on top to ‘P’ (you are advised to use a mains power adaptor for your camera model, to allow longterm use without the need for battery changes).
Follow the steps above for connecting AnalystAssist to the camera feed, however to view the live feed from your camera, you will need to select ‘EOS Webcam Utility Pro‘ from the ‘Camera’ drop-down selector at the bottom of the Live View panel. That should display the live feed from your camera.
Please Note: Due to the configuration of the EOS Webcam Utility Pro, it may be necessary to boost the ‘Brightness’ or ‘Exposure’ settings within the AnalystAssist Live View Settings panel to achieve a satisfactory image on screen.
Although the free version of EOS Webcam Utility Pro enables you to conduct analyses using your Canon DSLR, the definition of the image is determined by the model of Canon DSLR (better cameras may offer a sharper image due to data transfer limitations by USB output in more affordable models). Also the software may limit the output resolution to 720p rather than a High Definition image of 1080p, which will give a smaller field of view visible in AnalystAssist.
To increase the output resolution to 1080p, open the EOS Webcam Utility Pro software, click ‘My Subscription’ and start a subscription. Then return to the software, click the ‘Settings’ wheel top-right, and then ‘Video’ and select ‘1080p’. Restart the software and the next time you connect to AnalystAssist, you will see the higher-definition image.
