Then, the connection jack 4 of the beam projector module 2 is coupled to the connection jack 3 of the digital camera phone 42, and then the keypad 50 is used to control the still image or moving image by the image capturing unit 65. FIG. If an operation for reproducing a still image or a moving picture stored in a memory or a memory 51 or receiving a still image or a moving picture through the cellular phone circuit unit 44 is set, the image capturing unit 65 is controlled by the phone control unit 49. The memory 51 or the cellular phone circuit section 44 is driven so that a still picture or a moving picture is transmitted to the image generating circuit section 54 of the beam projector module 2 through the connecting jacks 3 and 4.

At this time, the control signal for controlling the driving of the beam projector module 2 output from the power supply unit 48 of the digital camera phone 42 and the phone control unit 49 is transmitted along with the image signal, that is, a still image or a moving image. do.

Therefore, the image generating circuit unit 54, which receives the still image or moving image image signal from the digital camera phone 42, generates an image for projecting on an external screen, wall, paper, or cloth, so that the image of the still image or moving image is projected. The unit 52 projects the external screen, the wall, the paper, the cloth and the like through the projection lens 5 together with the high brightness light source.

Hereinafter, a process of performing the beam projector function by combining the beam projector module 2 with a digital camera or a camcorder will be described with reference to FIGS. 4 and 5, and the same reference numerals are assigned to the same components as those shown in FIG. do.

First, as shown in FIG. 4, when the beam projector module 2 is coupled to the digital camera 64, the still image captured by the image capturing unit 65 is the digital camera controller 49 according to the manipulation of the keypad 50. The image is processed by the image processing unit 45 under the control of the image input / output unit 47 and displayed on the LCD 46 or stored in the memory 51.

In addition, after the connection jack 4 of the beam projector module 2 is coupled to the connection jack 3 of the digital camera 64, the image capture unit 65 captures a still image or a memory by operating the keypad 50. When an operation for reproducing a still image stored in the 51 is set, the image capturing unit 65 or the memory 51 is driven by the control of the digital camera controller 66 so that the still image is connected to the connecting jacks 3 and 4. It is transmitted to the image generating circuit section 54 of the beam projector module 2 through.

At this time, a power signal output from the power supply unit 48 of the digital camera 64 and a control signal for controlling the driving of the beam projector module 2 output from the digital camera controller 66 are transmitted together with the image signal, that is, the still image.

Therefore, the image generating circuit section 54 receiving the still image or moving image image signal from the digital camera 64 generates an image for projecting on an external screen, wall, paper, or cloth, so that the image of the still image or moving image By 52 is projected along with the high brightness light source through the projection lens 5 to an external screen, wall, paper, cloth or the like.

Next, when the beam projector module 2 is coupled to the camcorder 67 as shown in FIG. 5, the video captured by the image capturing unit 65 is controlled by the camcorder controller 68 according to the manipulation of the keypad 50. The image is processed by the image processing unit 65 and displayed on the LCD 46 through the image input / output unit 47 or stored in the memory 51.

In addition, after the connection jack 4 of the beam projector module 2 is coupled to the connection jack 3 of the camcorder 67, operation of the keypad 50 allows the image capturing unit 65 to capture a video or memory 51 When an operation for playing back a moving picture stored in the camera is set, the image capturing unit 65 or the memory 51 is driven under the control of the camcorder control unit 68 so that the moving picture is connected to the beam projector through the connecting jacks 3 and 4.

At this time, a control signal for controlling the driving of the beam projector module 2 output from the power supply unit 48 of the camcorder 67 and the camcorder control unit 68 is transmitted along with the image signal, that is, the video.

Therefore, the image generating circuit section 54 receiving the still image or moving image image signal from the camcorder 67 generates an image for projecting on an external screen, wall, paper, or cloth. 52 is projected together with the high brightness light source through the projection lens 5 to an external screen, wall, paper, cloth or the like.

3 to 5, an LCD or DLP image projection unit for generating and transmitting a high-intensity light source for projecting a still image or a moving image generated by the image generation circuit unit 54 onto the projection lens 5 ( Various embodiments of 52) will be described with reference to FIGS.

Before describing the LCD or DLP type image projector 52, a general single-plate or three-plate beam projector module will be described with reference to FIGS.

In the single-beam beam projector module disclosed in FIG. 6, the light emitted from the halogen lamp 8 in which the concave reflection mirror 7 for condensing is located at the rear has a condenser lens 9 and a flat convex lens for collecting light. 10) is transmitted to the transmissive LCD panel (11).

Then, the transmissive LCD panel 11 is driven by the control of the image generating circuit unit 13 receiving the image signal through the image signal input / output card 12, and the light transmitted to the transmissive LCD panel 11 is flat as a still image or a moving image. The convex lens 14 and the reflecting mirror 15 are transmitted to the projection lens 16.

Therefore, a still image or a moving image is displayed on an external screen, a wall, a cloth, or a paper positioned in front of the projection lens 16.

However, the single-beam beam projector module as described above is not suitable for the present invention, which requires a small volume because a high heat is generated in the halogen lamp used as the light source, so that a separate cooling fan 17 must be installed. In particular, the color efficiency of the transmissive LCD panel 11 significantly reduces the light efficiency.

In the three-plate beam projector module disclosed in FIG. 7, the white light emitted from the white light source 18 is separated into three source light by the red, green, and blue filters 19, 20, 21, and then directly or reflected mirror 22. To the mono LCD panels 24, 25, and 26.

Therefore, the light passing through the mono LCD panel 24, 25, 26 driven by the image signal is projected to an external screen, wall, cloth, paper, etc. through the projection lens 27, and is synthesized and displayed as a still image or a moving image. do.

However, the three-plate beam projector module as described above generates high heat in the white light used as the light source, has a large power consumption, and requires a large space for installing a plurality of filters.

In order to overcome the limitations of the single-plate or three-plate beam projector module as described above, the image projector 52 may be an LCD-based single-plate or three-plate beam projector module or a DLP-type single-plate or three-plate beam projector module. have.

Prior to describing various embodiments of the beam projector module as described above, a DLP method will be described.

DLP method is a new projection method using DMD (Digital Mirror Device) device developed by Texas Instruments (TI) in the United States, and by the on / off of reflection by DMD device, which is a collection of fine mirrors that are densely and tightly laid Projection of the image.

Here, since the DMD element has a single plate type or a three plate type as a mirror and does not reflect light in the off state, the amount of light at the portion becomes zero, so that a dark portion such as an LCD projector does not die. In particular, high brightness can be realized because the light is reflected rather than transmitted from the light source as in the LCD system.

The DMD device is a device that integrates hundreds of thousands of microscopic mirrors having a size of 16 μm into one chip and reflects light from a light source to display on a screen. This is controlled by rotating a fine mirror at a speed of 10㎲ at an angle of ± 10 degrees. Because of this, the displayed image is very bright, flexible and surprisingly detailed. Also, because it is a fully reflective device, the utilization of light is three times higher than that of a liquid crystal projector and five times higher than that of a three-plate projector.

8 shows an image projector 52 of a single plate type LCD system, in which a high intensity light source of white light emitted from a high intensity light emitting diode light source 69 receives an image signal of a still image or a moving image from a portable electronic device 54 Is projected onto the projection lens 5 via the single-color color LCD panel 71 which generates an image by means of?

Here, 70 and 72 are flat block lenses, 73 are reflecting mirrors, and 74 are concave reflecting mirrors.

9 and 10 show a three-panel LCD type image projection unit 52, which is different from the method in which one white light source is separated into red, green, and blue, and used as a mono LCD panel 28 (29) ( The red, green, and blue high intensity light emitting diode light sources 31, 32, and 33 corresponding to 30 are used. In addition, not only a high brightness light emitting diode but also a laser light source may be used as the high brightness light source.

That is, since the light emitted from the light emitting diodes, that is, the red, green, and blue high intensity light emitting diode light sources 31, 32, and 33, is transmitted to the mono LCD panels 28, 29, and 30, the digital camera phone or the digital The light passing through the mono LCD panels 31, 32, 33 driven by the image generating circuit unit receiving power, image signals, and various control signals from portable electronic devices such as cameras and camcorders is reflected to the reflection mirror 35. After the reflection is projected on the screen through the projection lens (5) are synthesized and displayed as a still image or moving image.

9 shows a single-plate DLP type image projector 52, which is composed of one red, green, and blue high intensity light emitting diode light source 75 that emits red, green, and blue high intensity light sources. The blue high-intensity light source sequentially emits light dynamically at a time difference and irradiates the DMD element 76.

Accordingly, the DMD element 76 driven by the image generating circuit unit receiving the still image or video image signal from the portable electronic device selectively reflects the red, green, and blue high intensity light sources emitted from the high intensity light emitting diode light source 75. By projecting onto the projection lens 5, a still picture or a moving picture is displayed on an external screen, a wall, a paper, a cloth, or the like.

Fig. 10 shows a three-plate type DLP image projection unit 52. The red, green, and blue high intensity light sources emitting from the three red, green, and blue high intensity light emitting diode light sources 77, 78, and 79 are shown. Three DMD elements 80, 81, 82 are irradiated.

Therefore, the DMD elements 80, 81, 82 driven by the image generating circuit portion receiving the still image or video image signal from the portable electronic device are irradiated from the high intensity light emitting diode light sources 77, 78, 79. By reflecting the green and blue high intensity light sources directly or via the reflective mirror 83 and projecting them onto the projection lens 5, a still image or a moving image is displayed on an external screen, a wall, a paper, a cloth, or the like.

As described above, a light emitting diode used as a high brightness light emitting diode light source for projecting still images or moving images at low power and high brightness has a structure in which a plurality of light emitting diodes (LEDs) are connected in parallel as shown in FIG.

That is, in the high brightness light emitting diode light source disclosed in Fig. 13, as shown in Fig. 14, a cathode 37 is disposed at the center of the body 36 formed into a cylindrical shape by epoxy resin, and the anode is surrounded by the anode 37. A plurality of light emitting diode chips 39 seated at 38 have a structure arranged radially. Of course, the light emitting diode chip 39 must be electrically connected to the cathode 37.

Also, a concave mirror 40 is embedded in the body 36 to reflect light generated from the light emitting diode chip 38 in a forward direction, and the light emitting diode chip 38 is located in front of the body 36. The condensing lens 41 for collecting light to one place irradiated with is integrally molded.

Therefore, the amount of light required for projecting still images or moving images is also obtained from light emitting diodes which consume less power and do not generate much heat.

Therefore, the present invention is a digital camera unlike the prior art in which a still image stored in a portable electronic device such as a digital camera phone, a digital camera, a PMP or a camcorder, or a still image captured by the portable electronic device has to view a video on a small screen such as an LCD. Separate beam projector modules can be separated into portable electronic devices such as phones, digital cameras, PMPs, and camcorders, and stored in portable electronic devices such as digital camera phones, digital cameras, PMPs, and camcorders, or by portable electronic devices. It is effective to realize a still image or a moving image that is enlarged to an external screen, a wall, a paper, a cloth, etc. located at a certain distance from the portable electronic device.

In particular, although the present invention increases the amount of light of the light source so that the image can be enlarged and projected on an external screen, the high power does not occur in the light source, the power consumption is lowered, and is coupled to the portable electronic device to perform the beam function of the projector. This reduces the volume of the projector module.
