An apparatus, a method and a computer program product for correcting image data for the presence of a ghost image. The image data is for acceptance by a device that includes a partially-silvered finite-thickness reflector or similar element to provide a reflection of an image for display. The ghost image is a shifted, attenuated version of the image data. The method includes subtracting a first correction term from the image data, the first correction term being a shifted and attenuated version of the image data, the shift being the same as that between the image data and the ghost image, and the attenuation matching the attenuation of the ghost image caused by the device. The processed image data is input to the device. For a small enough attenuation of the ghost image, substantially no ghost image of the image data is displayed by the device.
