PORTABLE ELECTRONIC APPARATUS WITH BEAM

PROJECTOR FUNCTION

Technical Field

[1] The present invention relates, in general, to a portable electronic apparatus having a beam projector function, such as a digital camera phone, a digital camera, a Portable Multimedia Player (PMP), a camcorder and the like. More particularly, the present invention relates to a portable electrode apparatus having a beam projector function, in which a beam projector module of a separate Liquid Crystal Device (LCD) or Digital Light Processing (DLP) type is integrally detachably coupled to a portable electronic device, such as a digital camera phone, a digital camera, a PMP, a camcorder and the like, whereby still or motion images, which are stored in the portable electronic device or are photographed by the portable electronic device, can be enlarged and implemented by being projected onto an external screen, the surface of a wall, paper, a fabric, etc., which are spaced apart from the portable electronic device at a predetermined distance. Background Art

[2] With the development of technology, the utilization of a portable electronic device, such as a digital camera phone, a digital camera, a PMP or a camcorder, is increased. In line with this trend, to meet consumers' various needs, multi-electronic devices emerges in which a variety of functions, such as a camera function, an Internet communication function and a MP3 function, are integrated into various portable electronic devices and a large capacity of a battery for driving the portable electronic devices is embedded.

[3] In general, a portable electronic device that has an additional function, such as a camera, and can photograph a still image or a motion image can store externally input or photographed still or motion images in its memory, display the images on a LCD, etc., which is integrally formed with the portable electronic device, or output the images to an external image device through a connection jack for connection with the outside.

[4] The visual organ of one of human's sense organs prefers large-scale data unlike the sense organs such as the ear, nose and skin.

[5] However, a portable electronic device, such as a digital camera phone, a digital camera or a camcorder having LCD mounted therein, has a small-sized LCD for displaying still images or motion images thereon. Accordingly, a user is not satisfied with the portable electronic device and, therefore, attempts to see the still or motion image through a separate image device having a large-size screen to which a variety of portable electronic devices are connected.

[6] However, in the case where the still images or the motion images are viewed through a separate image device having a large-size screen to which a variety of portable electronic devices are connected, it is advantageous in that the still images or the motion images can be seen with a large-size image, but is disadvantageous in that the portability, which is the greatest advantage of the various portable electronic devices, is lowered. Furthermore, since the image device having the large-size screen must be carried along with the various portable electronic devices, this method causes several inconveniences depending on the portability Disclosure of Invention Technical Problem

[7] Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to allow still or motion images, which are stored in a portable electronic device such as a digital camera phone, a digital camera, a PMP, a camcorder and the like or are photographed by the portable electronic device, to be enlarged and implemented by being projected onto an external screen, the surface of a wall, paper, a fabric, etc., which are spaced apart from the portable electronic device at a predetermined distance, in such a manner that a beam projector module with a reduced size, which includes a high-intensity light source capable of minimizing generation of heat and power consumption, is detachably coupled to the portable electronic device such as the digital camera phone, the digital camera, the PMP, the camcorder and the like. Technical Solution

[8] To achieve the above object, a portable electrode apparatus having a beam projector function according to an aspect of the present invention includes: a portable electronic device having a function of storing or photographing a still or motion image in realtime; and a beam projector module including an image-generating circuit unit for processing the still or motion image generated from the portable electronic device into an image to be projected onto an external screen, a wall, paper or a fabric, an image projection unit for irradiating a high-intensity light source for projecting the still or motion image, which has been generated by the image-generating circuit unit, onto the external screen, and a projection lens for enlarging the still or motion image, which has been projected from the image projection unit, and projecting the enlarged image onto the external screen, the wall, paper or the fabric. The portable electronic device and the beam projector module are formed integrally with each other.

[9] Furthermore, in an embodiment of the present invention, the image projection unit preferably includes a high-intensity light-emitting diode light source for emitting a white high-intensity light source, and a single plate type color LCD panel for irradiating the image generated by the image-generating circuit unit that has received an image signal of the still or motion image from the portable electronic device on the projection lens using the white high-intensity light source received from the white high-intensity light-emitting diode light source.

[10] Furthermore, in an embodiment of the present invention, the image projection unit preferably includes red, green and blue high-intensity light-emitting diode light sources for emitting red, green and blue high-intensity light sources, and a three-plate type mono LCD panel for irradiating the image generated by the image-generating circuit unit that has received an image signal of the still or motion image from the portable electronic device on the projection lens using the white high-intensity light source received from the white high-intensity light-emitting diode light source.

[11] Furthermore, in an embodiment of the present invention, the image projection unit preferably includes three red, green and blue high-intensity light-emitting diode light sources for emitting red, green and blue high-intensity light sources dynamically with a time lag, and a single plate type Digital Mirror Device (DMD) for irradiating the image generated by the image-generating circuit unit that has received an image signal of the still or motion image from the portable electronic device on the projection lens using the white high-intensity light source received from the white high-intensity light- emitting diode light source.

[12] Furthermore, in an embodiment of the present invention, the image projection unit preferably includes three red, green and blue high-intensity light-emitting diode light sources for emitting red, green and blue high-intensity light sources, and a three-plate type DMD for irradiating the image generated by the image-generating circuit unit that has received an image signal of the still or motion image from the portable electronic device on the projection lens using the white high-intensity light source received from the white high-intensity light-emitting diode light source.

[13] Furthermore, in an embodiment of the present invention, the high-intensity light- emitting diode light source includes a number of light-emitting diode chips, which are radially arranged in parallel at a central bottom of a body formed of epoxy resin, and a concave mirror disposed on a bottom surface of the light-emitting diode chips, for reflecting light emitted from the light-emitting diode chip forwardly. A condensing lens for condensing the light emitted from the light-emitting diode chips is detachably coupled to the high-intensity light-emitting diode light source at the front of the body.

[14] Furthermore, in an embodiment of the present invention, it is preferred that the portable electronic device be one of a digital camera phone, a digital camera, a PMP and a camcorder capable of storing or photographing a still image or a motion image. [15] Furthermore, in an embodiment of the present invention, it is preferred that the portable electronic device and the beam projector module be coupled to and decoupled from each other.

It is preferred that each connection jack include an emission line for transmitting an image signal, an electric line for supplying electric power, and a transmission line for transmitting a control signal to control the driving of the beam projector module. Advantageous Effects

[16] As described above, unlike the prior art in which still or motion images, which are stored in a portable electronic device such as a digital camera phone, a digital camera, a PMP or a camcorder, or are photographed by the portable electronic device, are viewed with a small screen such as a LCD, the present invention is advantageous in that still or motion images, which are stored in the portable electronic device such as the digital camera phone, the digital camera, the PMP or the camcorder or are photographed by the portable electronic device, can be enlarged and implemented by being projected onto an external screen, the surface of a wall, paper, a fabric, etc., which are spaced apart from the portable electronic device at a predetermined distance.

[17] In particular, the present invention is advantageous in that a high temperature is not generated in a light source and power consumption can be saved even though an amount of light of the light source is increased to the extent that an image can be enlarged and projected onto an external screen, and the volume of a beam projector module responsible for a projector function while being detachably coupled to the portable electronic device can be reduced.

Mode for the Invention

[31] The present invention will now be described in detail.

[32] FlG. 1 shows a portable electrode apparatus 1 having a beam projector function according to the present invention.

[33] The portable electrode apparatus 1, such as a digital camera phone, a digital camera, a PMP or a camcorder having a function of storing still or motion images in internal memory or photographing the images, includes a connection jack 3. The connection jack 3 can be detachably coupled to a beam projector module 2 mechanically and electrically.

[34] The connection jacket 3 includes an emission line for transmitting an image signal, an electric line for supplying electric power, and a transmission line for transmitting a control signal to control the driving of the beam projector module 2.

[35] It should be noted that the various lines formed in the connection jack 3 could be connected to common image devices capable of enlarging still or motion images output from a variety of portable electronic devices as well as the beam projector module 2.

[36] Furthermore, the beam projector module 2 includes a connection jack 4 for mechanical and electrical connection to the connection jack 3 of the portable electrode apparatus 1. The connection jack 4 is projected from a surface of a casing 6 in which a variety of constituent elements for the beam projector function are embedded. The connection jack 4 includes an emission line for transmitting an image signal, an electric line for receiving electric power, and a transmission line for receiving the control signal to control the driving of the beam projector module 2, in the same manner as the connection jack 3 of the portable electrode apparatus 1.

[37] Furthermore, a portion of a projection lens 5 for projecting still or motion images is projected from the casing 6 of the beam projector module 2. Accordingly, the projection lens 5 can project still or motion images onto an external screen 53, a wall, paper and a fabric as shown in FlG. 2. The portable electrode apparatus 1 and the beam projector module 2 can be coupled to and decoupled from each other as described above, but can be integrally formed in one casing.

[38] In the above embodiment, it has been described that the driving of the beam projector module 2 is controlled in the portable electrode apparatus 1. However, the present invention is not limited thereto, but a control unit for controlling the driving of the beam projector module 2, and an image processing unit or various buttons for processing still and motion images can be formed in the beam projector module 2.

[39] FIGS. 3 to 5 illustrate embodiments in which the beam projector module 2 is applied to portable electronic devices. In particular, FlG. 3 shows the internal constructions of a digital camera phone 42 and the beam projector module 2, which are coupled to each other in order to perform the beam projector function. A mobile phone circuit unit 44 can perform an operation for telephone call with a counterpart in the same manner as a common mobile phone under the control of a control unit 49 depending on the manipulation of a keypad 50.

[40] Furthermore, a still or motion image photographed by an image-capturing unit 65 is processed by an image processing unit 45 under the control of the phone control unit 49 depending on the manipulation of the keypad 50 and is then displayed on a LCD 46 or stored in memory 51 through an image FO unit 47. Furthermore, a still or motion image received through the mobile phone circuit unit 44 can also be displayed on the LCD 46 or stored in the memory 51 through the image I/O unit 47.

[41] Furthermore, if a photographing operation of a still or motion image by the image- capturing unit 65, a play operation of a still or motion image stored in the memory 51, or a reception operation of a still or motion image through the mobile phone circuit unit 44 is set by manipulating a keypad 50 after the connection jack 4 of the beam projector module 2 is coupled to the connection jack 3 of the digital camera phone 42, the image-capturing unit 65, the memory 51 or the mobile phone circuit unit 44 is driven under the control of the phone control unit 49, so that the still or motion image is transferred to an image-generating circuit unit 54 of the beam projector module 2 through the connection jacks 3, 4.

[42] At this time, electric power output from a power supply unit 48 of the digital camera phone 42 and the control signal for controlling the driving of the beam projector module 2, which is output from the phone control unit 49, are transferred to the image-generating circuit unit 54 of the beam projector module 2 along with the image signal (i.e., a still or motion image).

[43] Therefore, the image-generating circuit unit 54 that has received the image signal of the still or motion image from the digital camera phone 42 generates an image to be projected onto an external screen, a wall, paper or a fabric. Accordingly, an image projection unit 52 can project the still or motion image onto the external screen, the wall, paper or the fabric through the projection lens 5 along with a high-intensity light source.

[44] Hereinafter, a process of performing the beam projector function with the beam projector module 2 being coupled to the digital camera or the camcorder will be described with reference to FIGS. 4 and 5. The same reference numerals will be used to refer to the same parts as those of FlG. 3.

[45] First, in the case where the beam projector module 2 is coupled to a digital camera

64 as shown in FlG. 4, a still image photographed by an image-capturing unit 65 is processed by an image processing unit 45 under the control of a digital camera control unit 66 and is then is displayed on a LCD 46 or stored in memory 51 through an image I/O unit 47.

[46] Furthermore, if a photograph operation of a still image by the image-capturing unit

65 or a play operation of a still image stored in the memory 51 is set by manipulating a keypad 50 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-capturing unit 65 or the memory 51 is driven under the control of the digital camera control unit 66, so that the still image is transferred to the image-generating circuit unit 54 of the beam projector module 2 through the connection jacks 3, 4.

[47] At this time, electric power output from a power supply unit 48 of the digital camera 64 and the control signal for controlling the driving of the beam projector module 2, which is output from the digital camera control unit 66, are transferred to the image-generating circuit unit 54 of the beam projector module 2 along with the image signal (i.e., a still or motion image).

[48] Therefore, the image-generating circuit unit 54 that receives the image signal of the still or motion image from the digital camera 64 can generate an image to be projected onto an external screen, a wall, paper or a fabric. Accordingly, the image projection unit 52 can project the still or motion image onto the external screen, the wall, paper or the fabric through the projection lens 5 along with a high-intensity light source.

[49] In the case where the beam projector module 2 is coupled to a camcorder 67 as shown in FlG. 5, a motion image photographed by an image-capturing unit 65 is processed by an image processing unit 45 under the control of a camcorder control unit 68 depending on the manipulation of a keypad 50 and is then displayed on a LCD 46 and stored in memory 51 through an image I/O unit 47.

[50] Furthermore, if a photograph operation of a motion image by the image-capturing unit 65 or a play operation of a motion image stored in the memory 51 is set by ma- nipulating a keypad 50 after the connection jack 4 of the beam projector module 2 is coupled to the connection jack 3 of the camcorder 67, the image-capturing unit 65 or the memory 51 is driven under the control of the camcorder control unit 68, so that the motion image is transferred to the image-generating circuit unit 54 of the beam projector module 2 through the connection jacks 3, 4.

[51] At this time, electric power output from a power supply unit 48 of the camcorder

67 and a control signal for controlling the driving of the beam projector module 2, which is output from the camcorder control unit 68, are transferred to the image- generating circuit unit 54 of the beam projector module 2 along with the image signal (i.e., a motion image).

[52] Therefore, the image-generating circuit unit 54 that receives the image signal of the still or motion image from the camcorder 67 can generate an image to be projected onto an external screen, a wall, paper or a fabric. Accordingly, the image projection unit 52 can project the still or motion image onto the external screen, the wall, paper or the fabric through the projection lens 5 along with a high-intensity light source.

[53] Several embodiments of the image projection unit 52 of the LCD or DLP method, for generating and transferring the high-intensity light source for projecting the still or motion image generated by the image-generating circuit unit 54 onto the projection lens 5, as shown in FIGS. 3 to 5, will be described with reference to FIGS. 8 to 12.

[54] A general single plate type or three-plate type beam projector module will be described with reference to FIGS. 6 and 7 before the image projection unit 52 of the LCD or DLP method is described.

[55] In the single plate type beam projector module shown in FlG. 6, light emitted from a halogen lamp 8 in which a concave reflection mirror 7 for condensing is transferred to a transmission type LCD panel 11 through a condensing lens 9 for condensing light and a flat type convex lens 10.

[56] Furthermore, the transmission type LCD panel 11 is driven under the control of an image-generating circuit unit 13 that has received an image signal through an image signal I/O card 12, and transfers the received light to a projection lens 16 through a flat type convex lens 14 and a reflection mirror 15 as a still image or a motion image.

[57] Accordingly, the still or motion image is displayed on an external screen, a wall, a fabric or paper disposed at the front of the projection lens 16.

[58] However, the above single plate type beam projector module is not suitable for the present invention requiring a small volume because an additional cooling fan 17 must be installed due to high heat generated in the halogen lamp used as a light source. In particular, optical efficiency is significantly low due to color electrode lines of the transmission type LCD panel 11.

[59] In the three-plate type beam projector module shown in FlG. 7, white light il- luminated from a white light source 18 is separated into three primary colors by means of red, green and blue filters 19, 20 and 21 and are then transferred to mono LCD panels 24, 25 and 26 directly or through reflection mirrors 22 and 23.

[60] Therefore, the light that has passed through the mono LCD panels 24, 25 and 26 driven according to an image signal is projected and displayed on an external screen, a wall, a fabric or paper as a still or motion image through a projection lens 27 while being combined.

[61] However, in the above three-plate type beam projector module, high heat occurs in white light used as the light source, power consumption is great, and a wide space for installing a plurality of filters, etc. is required.

[62] To overcome the limits of the above single plate type or three-plate type beam projector module, the image projection unit 52 may employ a single plate type or three-plate type beam projector module of a LCD method, or a single plate type or three-plate type beam projector module of a DLP method.

[63] The DLP method will be described first before describing various embodiments of the beam projector module in detail.

[64] The DLP method is a new projection method employing the DMD, which was developed by Texas Instrument Inc. In this method, an image is projected by on/off of reflection by the DMD, which is a collection of micro mirrors closely spread with a high density.

[65] In this case, the DMD includes a single plate type or three-plate type as a mirror and does not reflect light in an off state. Therefore, since an amount of light at that portion becomes zero, a phenomenon in which a dark portion such as a LCD projector is not dead does not occur. In particular, the DMD does not allow light from the light source to pass therethrough like the LCD method, but reflect light. Accordingly, the DMD can realize high luminance.

[66] The DMD is a device in which hundreds of thousands of micro mirrors of 16 D in size are integrated into one chip. The DMD reflects light from a light source and displays the light on the screen. This is controlled by rotating the micro mirrors by an angle of 10 degrees at a rate of 10 D. This is because a displayed image is very bright and smooth and has a very fine image quality. Furthermore, since the DMD is a completely reflection type device, it has an excellent luminance in which the utilization of light is three times or higher compared with a liquid crystal type projector and is five times or higher compared with a three-plate type projector.

[67] FIG. 8 shows the image projection unit 52 of the single plate type LCD method. In the image projection unit 52, a white high-intensity light source emitted from a high- intensity light-emitting diode light source 69 is projected onto the projection lens 5 through a single plate type color LCD panel 71 that causes the image-generating circuit unit 54 that has received a still or motion image from a portable electronic device to generate an image. In FlG. 8, reference numerals 70 and 72 indicate flat type convex lenses, 73 indicates a reflection mirror, and 74 indicates a concave reflection mirror.

[68] FIGS. 9 and 10 show the image projection unit 52 of the three-plate type LCD method. Unlike the method in which one white light source is separated into red, green and blue colors, red, green and blue high-intensity light-emitting diode light sources 31, 32 and 33 corresponding to mono LCD panels 28, 29 and 30, respectively, are used. Furthermore, not only the high-intensity light-emitting diodes, but also a laser light source can be used as the high-intensity light source.

[69] That is, light illuminated from the light-emitting diode, i.e., the red, green and blue high-intensity light-emitting diode light sources 31, 32 and 33 are transferred to the mono LCD panels 28, 29 and 30. Accordingly, light, which has passed through the mono LCD panels 31, 32 and 33 driven by an image-generating circuit unit that has received electrical power, an image signal and various control signals from a portable electronic device, such as a digital camera phone, a digital camera or a camcorder, is reflected from a reflection mirror 35, combined while being projected on the screen through the projection lens 5, and displayed as a still or motion image.

[70] FlG. 11 shows the image projection unit 52 of the single plate type DLP method. A high-intensity light-emitting diode light source 75 of red, green and blue colors emits red, green and blue high-intensity light sources sequentially and dynamically, and irradiates the emitted light sources on a DMD 76.

[71] Therefore, the DMD 76, which is driven by the image-generating circuit unit that has received an image signal of a still image or a motion image from a portable electronic device, selectively reflects the red, green and blue high-intensity light sources irradiated from the high-intensity light-emitting diode light source 75 and projects them onto the projection lens 5. Accordingly, the still or motion image is displayed on an external screen, a wall, paper, a fabric or the like.

[72] FlG. 12 shows the image projection unit 52 of the three-plate type DLP method. In this image projection unit 52, red, green and blue high-intensity light sources emitted from three red, green and blue high-intensity light-emitting diode light sources 77, 78 and 79 are illuminated on three DMDs 80, 81 and 82.

[73] Therefore, the DMDs 80, 81 and 82, which are driven by the image-generating circuit unit that has received an image signal of a still or motion image from a portable electronic device, reflect red, green and blue high-intensity light sources irradiated from the high-intensity light-emitting diode light source 77, 78 and 79 directly or through a reflection mirror 83 and project them on the projection lens 5. Accordingly, the still or motion image is displayed on an external screen, a wall, paper, a fabric or the like. [74] As described above, the light-emitting diode used as the high-intensity light- emitting diode light source for projecting a still or motion image with low power and high intensity has a structure in which a number of LEDs are connected in parallel as shown in FIG. 13.

[75] That is, in the high-intensity light-emitting diode light source shown in FIG. 13, a cathode 37 is disposed at the center of a body 36 formed using epoxy resin in a cylindrical shape b, and a number of light-emitting diode chips 39 seated into anodes 38 are disposed in a radial direction around the cathode 37, as shown in FIG. 14. In this case, the light-emitting diode chips 39 are electrically to the cathode 37.

[76] Furthermore, a concave mirror 40 for condensing light generated from the light- emitting diode chips 38 and reflecting the light forwardly is built in the body 36. A condensing lens 41 for condensing light emitted from the light-emitting diode chips 38 is integrally formed at the front of the body 36.

[77] Therefore, an amount of light required to project a still or motion image can be obtained even from a light-emitting diode that has small power consumption and does not generated a lot of heat. Industrial Applicability

[78] As described above, unlike the prior art in which still or motion images, which are stored in a portable electronic device such as a digital camera phone, a digital camera, a PMP or a camcorder, or are photographed by the portable electronic device, are viewed with a small screen such as a LCD, the present invention is advantageous in that still or motion images, which are stored in the portable electronic device such as the digital camera phone, the digital camera, the PMP or the camcorder or are photographed by the portable electronic device, can be enlarged and implemented by being projected onto an external screen, the surface of a wall, paper, a fabric, etc., which are spaced apart from the portable electronic device at a predetermined distance.

[79] In particular, the present invention is advantageous in that a high temperature is not generated in a light source and power consumption can be saved even though an amount of light of the light source is increased to the extent that an image can be enlarged and projected onto an external screen, and the volume of a beam projector module responsible for a projector function while being detachably coupled to a portable electronic device can be reduced.
