Mouse Controlled movement not scrolling

I am designing a side scrolling application and want the player to use the mouse to move. However the mouse controlled movement area does not scroll with the rest of the application but is static in relation to the starting point of the player's object. Scrolling is automatic and this causes the player to get 'stuck' not being able to move right or left once they reach the edge of the window.

Is there any way to ensure that as the application scrolls the movement area scrolls with it?
