An image recording apparatus comprises a store for storing data representing an image, a cathode ray tube for displaying the image represented by the data in raster scan order and a camera for directing the displayed image onto film. A movable mask is positioned in front of the screen of the cathode ray tube. The mask defines an aperture which is moved over the screen of the tube as the image is displayed thereon so as to prevent unwanted light caused by the displaying of the image from being directed onto the film.
