Electronic Playback Apparatus with a Micro-Projector
An electronic playback apparatus. An image pickup unit receives an image of a target imaged through a lens when a photographic mode is in operation. A semiconductor light source module emits a plurality of visible light beams with different bands when a broadcast mode is in operation. A micro-display member receives the visible light beams with the different bands and modulates the visible light beams into an image beam. The image beam is projected onto a screen by the lens.
1 . An electronic playback apparatus, comprising:
a lens;
an image pickup unit receiving an image of a target imaged through the lens when a photographic mode is in operation;
a semiconductor light source module emitting a plurality of visible light beams with different bands when a broadcast mode is in operation; and
a micro-display member receiving the visible light beams with the different bands and modulating the visible light beams into an image beam, wherein the image beam is projected onto a screen by the lens.
2 . The electronic playback apparatus as claimed in claim 1 , further comprising a switching device disposed between the lens and the image pickup unit.
3 . The electronic playback apparatus as claimed in claim 2 , wherein, when the photographic mode is in operation, the switching device deviates from an optical axis of the lens such that the image of the target is imaged on the image pickup unit by the lens, and when the broadcast mode is in operation, the switching device moves onto the optical axis of the lens such that the image beam modulated by the micro-display member is reflected to the lens by the switching device.
4 . The electronic playback apparatus as claimed in claim 2 , wherein, when the photographic mode is in operation, the switching device moves onto an optical axis of the lens such that the image of the target is imaged by the lens and is reflected to the image pickup unit by the switching device, and when the broadcast mode is in operation, the switching device deviates from the optical axis of the lens such that the image beam modulated by the micro-display member is projected onto the screen by the lens.
5 . The electronic playback apparatus as claimed in claim 3 , wherein the micro-display member comprises a reflective micro-display member.
6 . The electronic playback apparatus as claimed in claim 3 , wherein the micro-display member comprises a transmissive micro-display member.
7 . The electronic playback apparatus as claimed in claim 4 , wherein the micro-display member comprises a reflective micro-display member.
8 . The electronic playback apparatus as claimed in claim 4 , wherein the micro-display member comprises a transmissive micro-display member.
9 . The electronic playback apparatus as claimed in claim 1 , further comprising a processor, wherein the processor saves the image, output from the image pickup unit, of the target as an image file when the photographic mode is in operation, and the processor modulates the micro-display member according to the image file to generate the image beam when the broadcast mode is in operation.
