Abstract: An image holder such as a picture album (10) includes a plurality of pages (14) that receive printed images (18). The pages (14) also have markers (20) placed thereon, with each marker corresponding to one of the images. A memory (25) stores audio segments associated with the respective images. A user may place the printed images in any order in the image holder. A controller (22) performs an initialization routine to match the image locations with corresponding audio segments for future playback. Once the initialization is complete, whenever a user selects a marker associated with an image, the audio segment associated with that image is played back.

Abstract: The digital projector comprises an array of light modulators displaying the image information. An optical system is arranged downstream of the light modulators and is made up of mirrors and/or prisms, with the mirrors and/or prisms being arranged such that the light beams coming from the individual light modulators are combined in front of a projection lens. For simplification of the optical system the light modulators are arranged in checkerboard formation.
