+## convertToScanRegionCoordinates
+
+Converts coordinates from the video's coordinate system to coordinates relative to the scan region.
+
+This is useful for overlaying HTML elements on top of specific points in the video, aligning with the page's layout.
+
+```typescript
+convertToScanRegionCoordinates(point: Point): Point;
+```
+
+**Parameters**
+
+`point`: a `Point` object representing the x and y coordinates within the video's coordinate system.
+
+**Return value**
+
+A `Point` object representing the converted x and y coordinates relative to the scan region.
+
+**Code Snippet**
+
+```javascript
+cameraEnhancer.convertToScanRegionCoordinates({x: 0, y: 0});
+```
