Menu bar Toolbar Thumbnail Image area Figure 2: NovaScope User Interface Capture tools 3.3. Understanding the Microscope Magnification A microscope magnification shows how many times a specimen is magnified by the lenses of the microscope. A magnification is presented by a number followed by the multiplication sign X. For example, if you want to see a specimen 50 times larger than the specimen's actual size, the magnification is 50X. - 8 -
3.3.1. Setting the Magnification on the NovaScope Microscope The NovaScope microscope offers two magnifications: 50X 200X These magnifications are marked on the microscope's Magnification knob. Figure 3: Magnification Knob You can set the magnification by rotating the Magnification knob on the microscope. Changing the magnification leads to enlarging or decreasing of the specimen's size in the Image area on your screen as shown on the figures below: - 9 -
Figure 4: 50X Magnification Figure 5: 200X Magnification 3.3.2. Focusing the Microscope Focusing the microscope properly enables you to see the fine details of a specimen. Although NovaScope does not provide manual focus adjustment capabilities, there are some techniques that can help you maximize your focus results. To focus the microscope: 1. Verify that the microscope tube touches the specimen. 2. Set the Magnification knob to the stop: On the right, when you want to set the magnification to 50X. On the left, when you want to set the magnification to 200X. - 10 -
3. Slowly rotate the Magnification knob until the specimen appears in focus. 4. If the specimen is still not focused, vertically move the microscope tube to find the best position such that the specimen is in focus. 3.4. Understanding the NovaScope Working Modes NovaScope can work in the following modes: Mode Preview Captured image or video view Annotation Description Displays the specimen currently under the microscope. Displays the image of a specimen that you previously captured as an image or video file. In this mode, the size of the displayed image fits the Image area on your screen. Enables you to draw on an image and add graphical and textual annotations. In this mode, the full size image is displayed. 3.5. Setting the Camera Resolution You can adjust the microscope's camera resolution to achieve higher clarity and readability. To set the camera resolution: 1. From the Microscope menu, select Microscope Settings. The Camera Settings dialog box is displayed. Figure 6: Camera Settings 2. In the Image Size drop-down list, select the resolution you need. - 11 -
NOTE: A higher resolution provides the higher quality of an image. At the same time, a higher resolution leads to a bigger size of a captured file. 3. Tap OK. The microscope captures images with the defined resolution. 3.6. Setting a Folder for Storing Image and Video Files NovaScope enables you to capture microscope images and save these images as still graphics or video files. You can specify the folder in which these files are stored. To specify a folder for storing image and video files: 1. From the Microscope menu, select Capture Settings. The Capture Settings dialog box is displayed. Figure 7: Capture Settings 2. Tap Change Folder. The Browse for Folder dialog box is displayed. 3.

You can also specify whether you want NovaScope to play a capture sound each time an image is saved to the file by enabling the Play Capture Sound check box. For more information, see Enabling and Disabling the Capture Sound. 3.7. Enabling and Disabling the Capture Sound When NovaScope successfully captures an image from the microscope as a still graphic, the application can imitate the sound of a photo camera shutter. This is an option that can be enabled or disabled. - 12 -
To enable the capture sound: 1. From the Microscope menu, select Capture Settings. The Capture Settings dialog box is displayed. Figure 8: Capture Settings 2. Enable the Play Capture Sound check box. If the checkbox is already enabled and you wish to disable the option, clear the checkbox. 3. Tap OK. 3.8. Achieving Best Results with the NovaScope System The microscope is connected to the USB port. However, the current version of the Nova5000 supports USB 1.1 only. This can slow down your Nova5000, especially when other applications are open while working with the NovaScope system. To achieve optimal performance, follow these recommendations: Before starting the NovaScope application, close all other applications. Do not open any other application while working with NovaScope. Do not use other Nova5000's USB ports for connecting devices other than the NovaScope microscope (for example, a USB mouse or a keyboard) while working with NovaScope. - 13 -
Chapter 4: Capturing Microscope Images You can capture microscope images and save them as image or video files. The following sections describe how you can capture images from the microscope. 4.1. Capturing Still Images NovaScope enables you to capture a microscope image and save it as an image file in the JPEG format. To capture an image: 1. Place a specimen on a tabletop or other flat, clean, steady surface. 2. Adjust the microscope tube so the tube touches the surface on which the specimen is placed. 3. On the microscope, set the optimal magnification using the Magnification knob. You can continue to adjust the picture until it appears correctly in the Image area on your screen. (For more information about magnification, see Understanding the Microscope Magnification.) 4. When the image previews correctly, tap Image Capture Mode. 5. Tap Capture, to capture a still image. When this is the first capture in the current session, the Set Magnification dialog box is displayed. In the Zoom drop-down list, select the magnification you are currently using and tap OK. NovaScope captures the image, and the image thumbnail is displayed in the Thumbnail pane. When this is not the first capture in the current session, NovaScope immediately captures the image, and the thumbnail is displayed in the Thumbnail pane. For images, NovaScope creates a JPEG file. By default, file names have the following format: IMG_nn.jpg, where nn is a sequential number, increasing automatically with each image file stored in the file folder. The captured image is displayed in the Image area. 6. To return to the Preview mode, tap. 4.2. Capturing Video NovaScope enables you to capture a microscope image as a video file in AVI format. - 14 -
To capture a video: 1. Place a specimen on a tabletop or other flat, clean, steady surface. 2. Adjust the microscope tube so the tube touches the surface on which the specimen is placed. 3. On the microscope, set the optimal magnification using the Magnification knob. You can continue to adjust the picture until it appears correctly in the Image area. (For more information about magnification, see Understanding the Microscope Magnification.) 4. When the image previews correctly, tap Video Capture Mode. 5. Tap Record to capture a video. The Stop button replaces the Record button and the video begins recording. In addition, the red circle is displayed on the top left corner of the image to further indicate that NovaScope is capturing content and storing it in a video file. Figure 9: Capturing a Video 6. When you want to stop recording, tap Stop. A thumbnail is displayed in the Thumbnail pane indicating the video has been captured successfully. For videos, NovaScope creates an AVI file. By default, file names have the following format: VID_nn.avi, where nn is a sequential number, increasing automatically with each video file stored in the file directory. - 15 -
Chapter 5: Viewing Images NovaScope enables you to view images and videos captured during the current session as well as during previous sessions. To view a still image or video captured during the current session: In the Thumbnails pane, double tap a thumbnail or a video you want to view. If the thumbnail represents an image file, the image is displayed in the Image area. If the thumbnail represents a video file, the video is displayed. To view a still image or video captured during a previous session: 1. On the toolbar, tap Open. The Open dialog box is displayed. 2. Locate the file you want to open and tap OK. The thumbnail of the image or video is displayed in the Thumbnail pane. 3. To view the image or play the video, in the Thumbnail pane, double tap the thumbnail. If the thumbnail represents an image file, the image is displayed in the Image area. If the thumbnail represents a video file, the video is displayed. - 16 -
Chapter 6: Using the Ruler Tool NovaScope enables you to measure the distance between two points in both Preview and Captured Image View modes. To perform this measurement, NovaScope provides the Ruler tool. The following sections explain how to configure the Ruler tool to optimize accuracy and how to work with the tool to measure the distance between two points. 6.1. Configuring the Ruler The accuracy of measuring the distance between two points depends on the following parameters: The magnification you are using. The NovaScope application does not automatically detect the current magnification. Instead, you need to specify the magnification manually. The distance between the microscope lens and the surface on which a specimen is placed. To adjust results of the measurement, NovaScope uses a parameter known as Factor. The Factor is the value by which the result of distance measurement is multiplied. When the NovaScope application performs the measurement, the program assumes that the microscope tube touches the surface on which a specimen is placed. In this case, the Factor is set to 1, which is the default value. However, in some cases the microscope tube cannot be adjusted in this way (for example, when a specimen is put on a slide). Because the distance between the microscope lens and the specimen is longer in this case, accuracy of the measurement is affected. In this case, you can manually specify another factor. The following sections explain how to specify these parameters along with other settings, such as measurement units and ruler color. 6.1.1. Configuring Ruler Settings To ensure accuracy of measuring, NovaScope enables you to specify the following parameters: Magnification Measurement units Factor Ruler color - 17 -
To configure ruler settings: 1. From the Microscope menu, select Ruler Settings. The Ruler Settings dialog box is displayed. Figure 10: Ruler Settings 2. In the Zoom drop-down list, select the current zoom. 3. In the Unit drop-down list, select measurement units. 4. In the Factor field, enter a new factor, if necessary. By default, the factor is 1. 5. Tap on the Color field and select a color for the ruler. 6. Tap OK. The Ruler tool now measures the distance between two points as defined. 6.1.2. Calibrating the Ruler When the NovaScope application performs the measurement, the program assumes that the microscope tube touches the surface on which a specimen is placed. You only need to calibrate the ruler when the microscope tube does not touch the surface on which the specimen is placed. In some cases the microscope tube cannot be adjusted in this way (for example, when a specimen is put on a slide). Because the distance between the microscope lens and specimen is longer in this case, the accuracy of the measurement is affected. To enable you to adjust the measurement, NovaScope enables you to manually specify the distance. This operation is known as ruler calibration. - 18 -
To calibrate the ruler: 1. Measure the distance between two points as described in Measuring Between Points. The ruler indicating the distance between two selected points is displayed. Figure 11: Ruler Measurement 2. From the Microscope menu, select Ruler Calibration. The Ruler Calibration dialog box is displayed. Figure 12: Ruler Calibration The Ruler Calibration dialog box displays the result of the current measurement. Because the program assumes that the microscope tube touches the specimen, the measurement result and the value in the Real Object Size field are the same. 3. To adjust the measurement, in the Real Object Size field, enter a new size. - 19 -
Figure 13: Updated Real Object Size 4. Tap OK. The Ruler tool now measures the distance between two points as defined. Figure 14: Calibrated Ruler Measurement As a result of the calibration, the factor is changed accordingly. You can check the new factor by opening the Ruler Settings dialog box as described in Configuring Ruler Settings. NOTE: After you change the position of the microscope tube, you need to recalibrate the ruler. 6.2. Measuring Between Points NovaScope enables you to measure the distance between two points on a microscope image. The behavior of the Ruler tool differs depending on the mode in which you use the ruler. - 20 -
The following table describes these differences: Mode Preview Captured image view Annotation Description The ruler is displayed over an image. The ruler does not become a part of the image. The ruler disappears when you do another measurement. You cannot add multiple rulers on an image. Once added, the ruler becomes a part of the image. You cannot remove the ruler from the image. You can add multiple rulers on an image. For more information about annotations, see Annotating Images. To measure between two points: 1. On the toolbar, tap Ruler. 2. In the Image area, click on the location where you wish to begin measuring and then move the stylus between the starting point and the point you wish to measure. The connecting line is displayed. In addition, the distance is displayed in the measurement units as defined. Figure 15: Using the Ruler Tool NOTE: You can change a color of the ruler as described in Configuring Ruler Settings. - 21 -
Chapter 7: Annotating Images NovaScope enables you to annotate images by drawing on the image. This is especially useful when you want to graphically highlight a specific element on the image and provide notes about this element. Once an annotation is added, it becomes a part of the image and cannot be removed from the image. To keep your original image intact, it is recommended that you keep an original image without annotations and the image with annotations in two separate files. To annotate an image: 1. Open the image as described in Viewing Images. 2. On the toolbar, tap Annotations Mode. The annotations toolbar is enabled. In addition, the full size image is now displayed in the Image area. You can use the horizontal and vertical scrollbars to locate the area on the image you want to annotate. Figure 16: Full Size Image in the Annotation Mode 3. To select a color for the annotations, tap the color palette and select the color. NOTE: The color of an annotation that has already been added to the image cannot be changed. 4. On the toolbar, tap one of the following annotation tools: - 22 -
Icon Tool Effect Pencil Draws a freeform line. Line Rectangle Circle Arrow Text Region Ruler Draws a straight line. Draws a square or rectangle. Draws an ellipse or circle. Draws an arrow. Draws an area in which you can enter a text. Enables you to select a region on an image. You can copy a part of the image within this region to other applications. Draws a straight line and indicates the distance between two points. In the Annotation model, the ruler is used as an annotation tool. This means the rule is added as part of the image. 5. In the Image area, add an annotation. You can add as many annotations as you want. 6. To finish annotating the image, tap Annotations Mode. The image size fits the Image area again. Figure 17: Image Annotations - 23 -
7. To complete the process, you should now do one of the following: To leave the original image intact and save a copy of the original image with annotations, tap Save and enter a new file name. A new file is saved, leaving the original file as it was originally. To save annotations as a part of the original image, tap Save. The file is updated. - 24 -
Chapter 8: Copying Images to Other Applications You can copy images or parts of images to other applications. This feature enables you to forward images or further process these images using additional graphics tools. For example, you can capture an image and then edit this image in a third-party image editor. To copy an image: 1. Open an image as described in Viewing Images. 2. On the toolbar, tap Annotations Mode. 3. To copy an entire image, from the Edit menu, select Copy. The image has been stored in the clipboard and can now be pasted elsewhere, as detailed below. If you want to copy a region, skip this step. 4. To copy a particular region of an image, tap Region. 5. In the Image area, drag the stylus diagonally in the direction you need. The selected region is marked with the dot line on the image. Figure 18: Region Selection 6. From the Edit menu, select Copy. The copied image is now copied into the Windows clipboard. Paste it to another application using standard Windows functionality (for example, Ctrl+V). - 25 -
Chapter 9: Saving and Deleting Files After a microscope image is captured, you can create a copy of this file for further processing (for example, for annotating an image while preserving the original image intact). You can also change the extension of the image file (for example, you can save a JPEG file as a BMP file). In addition, you can reset the automatic enumeration of file names. 9.1. Creating a Copy of a File NovaScope includes the ability to copy files by saving them under a different name. The original file continues to be stored in your file system and a new file, using the new name, is stored as well. While saving a copy of the file, you can also change the graphic format. To create a copy of a file: 1. Open an image as described in Viewing Images. 2. From the File menu, select Save Capture As. The Save As dialog box is displayed. 3. Enter a new name and select a new type, if necessary. 4. Tap OK. A copy of the file is created in the Nova5000 storage. 9.2. Resetting Image Index When NovaScope creates an image or video file, the file receives an automatically generated name that consists of IMG_ (for images) or VID_ (for) videos followed by a number. This number automatically increases by one every time a new file is created. This number is known as index. In some cases, you may want to reset index. To reset index: 1. From the Microscope menu, select Capture Settings. The Capture Settings dialog box is displayed. 2. Select the Reset Image Index check box. 3. Tap OK. - 26 -
9.3. Deleting Files NovaScope enables you to easily delete files that have been stored on the Nova5000 memory card. You have the option of deleting an individual file, or all files from a selected folder. The same process is followed regardless of whether the file is an image file or a video file. To delete individual files: 1. In the Thumbnail pane, double tap the image you want to delete. 2. From the File menu, select Delete File. The confirmation window is displayed. 3. Click Yes to confirm your selection. The file is permanently deleted from the Nova5000 storage. To delete all files in the folder: 1. From the Microscope menu, select Capture Settings. 2. Click Empty Folder. The confirmation window is displayed. 3. Click Yes to confirm your selection. All files stored in the folder are permanently deleted from the Nova5000 storage. - 27 -
Chapter 10: Troubleshooting 10.1. Installing and Uninstalling NovaScope Problem When installing NovaScope the following message is displayed: "The file '\Windows\zc030x.dll' is in use or in ROM. If the file is not in ROM, please close the application using the file. Possible Cause The microscope must be disconnected from the Nova5000 when installing NovaScope. Solution 1. Disconnect the microscope from the Nova5000. 2. Run the installation file again. 10.2. Starting NovaScope Problem When starting the NovaScope application, the following message is displayed: "Microscope cannot be found." Possible Cause The microscope is not connected to the Nova5000. Solution 1. Connect the microscope to the Nova5000. 2. Start NovaScope again. 10.3. Lack of Response from the NovaScope Application Problem In the Preview mode, the image of a specimen is frozen. Movements of the specimen or changing the magnification are not reflected on the screen. - 28 -
Possible Causes Cause #1 The Nova5000 processes images received from the microscope too slowly. The current version of the Nova5000 supports USB 1.1 only. In some cases, this can significantly slow down the Nova5000 and even cause hanging. Solution 1. Exit from the NovaScope application. 2. Start NovaScope again. Cause #2 After you captured an image, the Image area displays the captured image rather than the live preview of a specimen under the microscope. Therefore, any movements of the specimen or changes in the magnification are not reflected. Solution To return to the Preview mode, tap. Problem Overall performance of the Nova5000 has slowed down. Possible Cause The current version of the Nova5000 supports USB 1.1 only. In some cases, this can significantly slow down the Nova5000 and even cause hanging. Solution 1. Close all other applications. 2. Unplug any devices other than the NovaScope microscope (such as USB keyboard and mouse) from all Nova5000 USB ports. 10.4. Ruler Measurements Problem The results of the measurement done with the Ruler tool are not accurate. Possible Cause When the NovaScope application performs the measurement, the program assumes that the microscope tube touches the surface on which a specimen is placed. However, in some cases the microscope tube cannot be adjusted in this way (for example, when a specimen is put on a slide). Because the distance between the microscope lens and specimen is longer in this case, accuracy of the measurement is affected. - 29 -
Solution 1. Verify that the microscope tube touches the specimen. If the microscope tube cannot be adjusted in this way (for example, when a specimen is put on a slide): 2. Perform the measurement using the Ruler tool. 3. From the Microscope menu, select Ruler Settings. 4. In the Ruler Settings dialog box, in the Factor field, enter a new value and tap OK. NovaScope multiples the result of the measurement by this value. - 30 -
