Abstract

A portable image-capturing device with embedded projector comprises a control integrated circuit; an image-capturing module coupled to said control integrated circuits for capturing an image; a memory coupled to said control integrated circuits for storing said captured image; a projection module coupled to said control integrated circuits to project said captured image stored in said memory or from an external device outside said portable image-capturing device; wherein said projection module includes a color control module coupled to a light source unit for switching said light source unit to emit R, G, B color light in sequence; a reflective-type panel coupled to said control integrated circuits so as to reflect light fed from said light source unit; and a projection lens positioned in the reflected light path from said reflective-type panel to project the image.

Claims

1. A portable image-capturing, two-way communication device comprising:

a control integrated circuit;

a wireless communication module coupled to the control integrated circuit and configured for two-way wireless communication with one or more other two-way communication devices;

an image-capturing module coupled to said control integrated circuit;

a memory coupled to said control integrated circuit; and

a projection module coupled to said control integrated circuit, wherein said projection module is configured to project an image stored in said memory or in an external device outside said portable image-capturing device, wherein said projection module comprises;

a light source unit;

a reflective-type device coupled to said control integrated circuit, said reflective-type device configured to reflect red, green, and blue light emitted from said light source unit to a screen; and

a color combiner coupled to said light source unit, said color combiner configured to combine red, green, and blue light emitted from said light source unit,

wherein said light source unit comprises red, green, and blue light sources at one side of said color combiner, and wherein said reflective-type device comprises three reflector mirrors arranged in line to reflect said red, green, and blue light from said light source unit, respectively.

2. The portable image-capturing, two-way communication device of claim 1, wherein said light source unit comprises a plurality of elements configured to emit red, green, or blue light, the plurality of elements selected from the group consisting of an OLED element, an LED element, a laser diode, an electroluminescence element, and a field-emitting element.

3. The portable image-capturing, two-way communication device of claim 1, wherein said light source unit comprises red, green, and blue light sources adjacent to said color combiner.

4. The portable image-capturing, two-way communication device of claim 1, wherein said projection module further comprises a color control module coupled to said light source unit, wherein said color control module is configured to switch said light source unit to emit red, green, and blue light in sequence.

5. The portable image-capturing, two-way communication device of claim 1, wherein said projection module further comprises a projection lens.
