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 corridors. In order to draw a corridor instead of a rectangle in the live image, keep [Ctrl+Shift] pressed and click in the live image. In order to define the direction and length of the counting corridor, hold down the [Shift] key and click again into the live image. The next click sets the width of the counting corridor. Then click on the button in the dialog to add the counting corridor definition to the corresponding definition field.
- 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.
