Added

Restoring image capture conditions

Automatic restoration of light source settings is now available when comparing images with live video. When you select an image in a comparison group, the software automatically applies the light source used to capture the selected image to the live video. If no light source information is available, automatic switching does not occur.

To restore image capture conditions, follow these steps:

1. On the Database tab, in the Examinations panel, select the image group you created.
2. Right-click the image group and add it to Comparison as either the reference or the examined item.
3. Open the Comparison tab and select Live video for comparison. As you switch between images in the group, the light source settings used to capture each image are automatically restored for the live video.

Restoring capture conditions from the context menu

The Restore conditions command has been added to the image context menu. You can now restore image capture conditions directly from the file list by right-clicking an image and selecting the corresponding command. This feature is available only for supported images.

To restore image capture conditions, follow these steps:

1. In the Examinations panel, select an image.
2. Right-click the image.
3. Select Restore conditions. The Device tab opens with the same light source settings that were used to capture the image.

Saving images in PSD format

You can now save images in PSD (Adobe Photoshop Document) format for further editing in image editors.

To save images in PSD format, follow these steps:

1. In the upper-right corner of the screen, open the menu and select Settings.
2. On the Database tab, select the .psd from the Image extension drop-down list.

Using 5000 K white light with other light sources

Added the ability to use 5000 K white light together with supported spectral light sources to improve the visibility of the examined object.

When a light source is selected, the Backlight checkbox appears, allowing users to additionally enable 5000 K white light without brightness adjustment. When enabled, the white light is activated directly on the device, allowing users to visually check the position of the document on the working surface.

Saving individual images captured in automatic IR luminescence mode

You can now extract a selected image from a group of automatic IR luminescence capture results without saving the entire group. Information about the light source and filter used is preserved in the extracted image’s metadata.

Adding HSA graphs to reports

HSA graph comparison results can now be included in reports. The report contains images, information, and measurement areas for each HSA result, as well as the selected wavelength and a combined comparison graph.

Comparing HSA graphs

Added the ability to compare HSA charts to analyze the hyperspectral characteristics of objects whose images were captured under the same conditions.

To compare HSA charts, follow these steps:

1. In the Examinations panel, select a saved hyperspectral analysis examination. Right-click and select Add as reference from the context menu.
2. In the Examinations panel, select another hyperspectral analysis examination for comparison and click Add as examined from the context menu.
