Map coordinates to camera coordinates

I have a tiled map which is 3 times higher than camera. When I press on a tile, I want an actor on that tile to show up. This works if camera is not moved. If I move camera a little bit up, so the tile coordinates are greater then camera coordinates, actor is placed offscreen. Is there a way to get tile coordinates so they wil fit the camera coordinates

Im using libgdx if it helps.
