The present invention relates to a mobile phone having a camera that can replace the lens, and more specifically, to a mobile phone having a camera so that the lens attached to the camera can be replaced by exchanging a lens capable of capturing images by various lenses. It relates to a mobile phone having a camera that can be.

There are many types of lenses used in cameras. For example, a lens is a shorter focal length than a standard lens, a single lens used to record a large number of subjects in a narrow space, a lens having a focal length similar to the diagonal length of the film used, and an angle similar to a human's field of view. There are standard lenses used when demanding the expression of a lens, telephoto lenses used to remove perspective with a longer focal length than standard lenses, and fisheye lenses that can take a distorted picture with an extremely short focal length.

However, conventionally, a mobile phone having a camera including only one lens has been commercialized. As a result, a conventional mobile phone having a camera including only one lens has a problem in that various images cannot be taken with respect to one image.

In addition, in response to the development of lens technology, consumers demand a qualitative improvement of the lens function in a mobile phone equipped with a camera, but a mobile phone equipped with a camera including only one conventional lens does not correspond to the demand of these users. Had a problem.

Accordingly, an object of the present invention is to provide a mobile phone having a camera that can exchange various lenses.

In addition, an object of the present invention is to perform a shooting with a variety of lenses for a single image to correspond to the quality requirements for the lens function of the consumer by inducing the interest of the consumer and a mobile phone having a camera that can promote the sale of the mobile phone In providing.

According to a first aspect of the present invention to achieve the above object, a mobile phone having a camera, comprising: a lens unit having at least two interchangeable lenses; A lens driving unit which drives the lens unit to be interchanged under the control of a control unit; A sensor unit configured to generate an image signal by detecting an image captured by one of the lenses of the lens unit; A display unit which displays an image included in the image signal; An RF unit transmitting the video signal to a terminal connected to a wired or wireless network; And a control unit for controlling the lens driving unit, the sensor unit, the display unit, or the RF unit.
Here, the lens of the lens unit may be exchanged by the rotation of the lens drive unit.
The apparatus may further include a camera interface unit which transmits an image signal received from the sensor unit to the display unit or the control unit, and receives a control signal necessary for control from the control unit and transmits the control signal to the sensor unit or the display unit.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a mobile phone having a camera that can replace the lens according to the present invention will be described in more detail.

1 is a circuit diagram of a mobile phone having a camera according to an embodiment of the present invention. Referring to FIG. 1, a mobile phone having a camera includes a lens unit 101, a sensor unit 103, a camera interface unit 105, a display unit 107, a control unit 109, and an RF (radio frequency) unit. 111, an antenna unit 113, a lens driver 115, and a keypad 117.

The lens unit 101 captures an image by collecting or diverging light from an object. The lens unit 101 is provided with the above-described various types of lenses, and the lens driver 115 may replace the lenses.

The lens driver 115 serves to replace the lens of the lens unit 101 under the control of the controller 109. The lens driver 115 may be configured as a small motor.

The sensor unit 103 serves to generate an image signal that is an electrical signal by sensing an image captured by the lens. Thereafter, the sensor unit transmits an image signal to the camera interface unit 105.

The lens unit 101 and the lens driver 115 will be described in detail with reference to FIG. 2. 2 is an exemplary view of a mobile phone having a camera that can replace the lens according to an embodiment of the present invention.

2, reference numeral 201 shows a plan view of a mobile phone. Reference numeral 203 is an enlarged analysis of a camera having a replaceable lens. Specifically, reference numerals 205, 207, and 209 denote a lens 101, reference numeral 211 denotes a lens driving unit 115, and reference numeral 213. Is a connection portion between the lens 101 and the lens driver 115.

Although the number of interchangeable lenses is three in the embodiment of Figure 2, it is apparent to those skilled in the art that two or four or more lenses can be interchanged according to another embodiment of the present invention.

Reference numeral 215 denotes a sensor unit. Currently, the sensor unit 215 captures an image by the single lens 205. The lens driver 213 is rotated under the control of the controller, and the rotational force of the lens driver 213 is transmitted to the lenses 205, 207, and 209 through the connection unit 213. As a result, when the lenses 205, 207, and 209 are rotated, the sensor unit 215 can capture an image by the telephoto lens 207 or the standard lens 209 selected by the rotation.

Referring back to FIG. 1, the camera interface unit 105 serves to interface the sensor unit 103, the display unit 107, and the control unit 109. In detail, the camera interface unit 105 receives an image signal from the sensor unit and transmits the image signal to the control unit 109 and the display unit 107. In addition, the camera interface unit 105 serves to transmit to the sensor unit 103 or the display unit 107 by a control signal of the control unit.

The display unit 107 serves to display an image included in an image signal under the control of the controller 109. In addition, the display unit 107 may display the state of the current lens.

The controller 109 processes the image signal as a central part of the mobile phone, and controls and controls the sensor unit 103, the display unit 107, the RF unit 111, and the lens driver 115. Specifically, when the user of the mobile phone transmits the lens exchange signal through the keypad 117, the controller 109 controls the lens driver 115 to replace the lens of the lens unit 101.

The RF unit 111 transmits an image signal to a terminal connected to a wired or wireless network through the antenna unit 113. The terminal may be at least one of a computer, a mobile communication terminal, a PDA, and an IMT-2000 terminal.

According to another preferred embodiment of the present invention, the lens of the camera may be replaced manually without the lens driving unit.

3 is an exemplary view of a camera capable of manually exchanging a lens according to another exemplary embodiment of the present invention.

Referring to FIG. 3, the lens replacement unit 307 may be provided instead of the lens driver. Reference numeral 311 is an enlarged view of the lens replacement means 307. The lens exchange means 307 is composed of the contact means 313, 315 and the support means 317.

The contact means 313, 315 is coupled to the connecting portion 307 coupled with the lens 301, 303, 305 to connect the lens replacement means 309 so that the rotational force of the lens replacement means 309 can be transmitted without being lost. 307 and a role to combine.

The support means 317 is configured as a resilient material, such as rubber or spring. As a result, when the user of the mobile phone applies pressure, the lenses 301, 303, and 305 and the connection part 307 can be easily separated from the case of the mobile phone and rotated.

That is, the user depressurizes the lens replacement means 307 to separate the lenses 301, 303, and 305 from the case of the mobile phone, and then applies rotational force to the lenses 301, 303, and 305 and the connector 307. ), The lenses 301, 303, and 305 are replaced.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art to which the present invention pertains without departing from the spirit and scope of the present invention as set forth in the claims below It will be appreciated that modifications and variations can be made.

A mobile phone having a camera capable of exchanging a lens according to the present invention allows a user to shoot a single image using various lenses, thereby inducing interest of the consumer by selling to the user by responding to a qualitative demand for the lens function of the consumer. There is an effect that can be promoted.
