Graphically Entering Image Areas
Some of the camera features, such as Video Motion Window (VM), Obscure Image Area (OA), Exposure Windows, Custom Size and Free Zoom / Crop options use windows within the image sensors that you can define and modify for the corresponding image sensor or the visible image section using graphical means.
Defining New Windows
- Open the camera's Live image.
- Hold down the [Shift] key and left-click inside the displayed image with your mouse. This spot is highlighted in yellow.
- Release the [Shift] key and click on a second spot of the image area. The selected image area is now displayed as a yellow frame in the live image.
Hold down the [Ctrl] key during this step to define a rectangle that has the same proportions as the current image format (default is 4:3).
- Then click on the button in the dialog to add the rectangle coordinates to the corresponding definition text field.
Note: Note that the MxAnalytics functions include the definition of counting lines. In order to draw a line instead of a rectangle in the live image, keep [Ctrl+Shift] pressed and click in the live image. Click a second time to mark the end of the line. You can use a button next to the corresponding definition text field to enter the line's coordinates.
- The yellow frame in the live image disappears after the coordinates have been entered in a definition box by clicking on one of the buttons or the zoom feature, or after 60 seconds at the latest. After first [Shift]-clicking, the camera will wait 10 seconds for you to follow up with a second click.
- If images or video sequences are stored while the yellow marker or the yellow frame are displayed (i.e. due to events or by a time task), the yellow elements will also be stored.
- If you select a rectangle for Custom Size while displaying two images side-by-side (Camera Selection Quick Control: Both), the same area will be used on both image sensors, i.e. the visible image will be twice as wide as the selection.
- The camera always clips the rectangle at the border between the images when the camera shows both image sensors. Selecting one area from both sensors is not possible.
