Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile phone terminal with a built-in camera function, and in particular, has both a bidirectional communication using a camera and a liquid crystal display screen and a function as a normal mobile phone.
[0002]
[Prior art]
As an example of a conventional mobile phone terminal with a built-in camera, as shown in FIG. 4, there is one in which the mounting position of the camera unit (100) is arranged on a surface facing the liquid crystal display screen (display unit 11) of the terminal. In FIG. 1, a main body 1 is a liquid crystal display screen, a display unit 11, an operation unit 12 for performing a user input operation, a speaker 7 for a receiving unit, a microphone 13 for transmission, and a front surface ( Arranged in FIG. 5 a), the battery 15, the camera of the photographing means (the image sensor of the camera is, for example, CCD or C-MOS) 100, and the photographing range captured by the camera 100 are grasped. The mirror 200 is disposed on the back surface (b) of the main body, and the antenna 14 is disposed on the top surface.
[0003]
When shooting a subject using the camera 100 with this terminal, normal camera shooting is performed while checking on the liquid crystal display screen. In other words, the camera 100 facing the display unit 11 is directed toward the subject in the shooting direction, and the liquid crystal display screen side on which the subject captured by the camera is displayed is directed toward the user. Thereby, the image captured by the camera can be confirmed in a state where it is actually stored.
[0004]
In another conventional example in which only the camera 100 is attached without the mirror 200, when the user takes a picture of himself / herself, the camera 100 is pointed in his / her direction, and the range in which the camera 100 is captured is predicted. Since there were many cases where the intended shooting was not performed because of shooting, it was considered to attach a mirror 200 as shown in FIG.
[0005]
However, it is difficult to accurately grasp the image range captured by the camera 100 only by providing a member such as the mirror 200, and it is not always possible to capture an image intended by the user. In addition, since the state that can be confirmed by the user varies greatly depending on the reflection performance of the mirror 200, it has been difficult to realize that the reflection performance continues to be constant.
[0006]
Therefore, it is conceivable to provide a second display unit instead of the mirror 200. Thus, providing the second display unit separately from the display unit on the front also leads to an increase in cost, and the problem of the location of the second display unit and the circuit for controlling the display unit There is a placement problem.
[0007]
As another conventional method, it is conceivable to attach a camera to the front shown in FIG.
[0008]
However, operation keys, a speaker (receiving unit), a microphone (sending unit), etc. are arranged on this surface, and if it is a compact portable terminal, there are more restrictions on the location, and the place where the camera is arranged Difficult to secure.
[0009]
Even if the camera can be placed near the earpiece with ample space, when the user's ear is placed against the earpiece, a part of the user will come into contact with the camera lens. The camera lens may get dirty. In such a case, when using the camera, there is a high possibility that the photographed image will be stained, and the image intended by the user cannot be obtained.
[0010]
[Problems to be solved by the invention]
In the conventional mobile phone terminal described above, when the cameras are integrated, the place restrictions are greatly affected, and as a result, the image from the camera intended by the user cannot be obtained.
[0011]
Further, providing a camera space by enlarging the structure of the terminal itself is contrary to downsizing, and there is a problem that the portability of the user is deteriorated.
[0012]
An object of the present invention is to provide a mobile phone terminal with a camera that can capture an image intended by a user without increasing the size of the terminal.
[0013]
[Means for Solving the Problems]
The present invention includes communication means for performing communication, display means for displaying information, operation means for operation by a user, and imaging means capable of displaying captured information on the display means. In the cellular phone terminal, the imaging unit is provided on the same surface on which the display unit is disposed, and the cellular phone terminal is provided with a cover unit that covers the imaging unit at the first position and exposes the imaging unit at the second position. To do.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an external view showing an embodiment of a mobile phone terminal according to the present invention. The same parts as those of the conventional example are denoted by the same reference numerals, and description thereof is omitted.
[0015]
Reference numeral 1 denotes a main body of a mobile phone terminal, which includes an operation unit 12 such as a numeric keypad and function keys. Reference numeral 2 denotes a slide cover attached to the main body 1 by a rail-like hook 3 so as to be movable in the longitudinal direction of the main body 1. Reference numeral 4 denotes a transmission portion of the slide cover 2 (for example, a transmission night of an in-mold molded product). The through-hole 6 for the camera is a camera, and examples of the image pickup element include a CCD and a C-MOS. 8 is an earphone microphone socket into which the terminal of the earphone microphone is inserted, 9 is a detection switch for detecting the open / closed state of the slide cover 2, 10 is a printed circuit board, 11 is electrically connected to the circuit of the printed circuit board 10, and It is a display unit (for example, a liquid crystal display) that performs display, camera image display, and the like.
[0016]
FIG. 1 is a view showing a state in which the slide cover is in the first place. FIG. 3A is a view of the surface of the operation unit 1a of the main body 1 as viewed from the front, and the display unit 11 is also the front. FIG. 6B is a view seen from the side of the surface of the operation unit 1a, and the earphone microphone socket 8 is on this side.
[0017]
This first place is a state in which the slide cover 2 covers the camera part, and the sounding hole located near the center of the speaker 7 is in a state coincident with the position of the through hole 5, and the speaker 7 is smoothly provided. The sound from is output. In this state, the camera 6 is covered with the slide cover 2 and is in an unusable state. Further, the detection switch 9 is not pressed, and the power supply driving of the camera itself and signal processing by imaging are turned off.
[0018]
Furthermore, there is no display unit 11 in the upper part of the transmission unit 4, and the main body mold is visible (4a). In addition, display items such as logos and marks can be displayed on the cabinet part of the main unit. By allowing the user to directly create display items such as brand names and terminal names, Display can be made.
[0019]
The display unit 11 visible from the transmission unit 4 displays various information depending on the operation of the user and the state of the terminal. In addition, stored images such as captured image information, images obtained through communication, and the like are displayed.
[0020]
Next, the case where a camera is used will be described with reference to FIG. FIG. 3A is a view of the surface of the operation unit 1a of the main body 1 as viewed from the front, and the display unit 11 is also the front. FIG. 6B is a view seen from the side of the surface of the operation unit 1a, and the earphone microphone socket 8 is on this side.
[0021]
FIG. 2 shows the slide cover 2 when it is in the second location.
[0022]
The second place is a state in which the slide cover 2 does not cover the main body most, and the slide cover 2 is slid further toward the center of the main body than the first place. Further, the sound reporting hole located at the approximate center of the speaker 7 is covered with the slide cover 2, that is, shifted from the position of the through hole 5 and is not visible through the through hole 5.
[0023]
That is, in this case, in order to use the camera function, the speaker 7 that is not particularly necessary is covered with the slide cover 2, and no sound is output from the speaker 7. Note that, by connecting an earphone microphone, it is possible to confirm the sound without outputting the sound from the speaker 7.
[0024]
In this state, what was covered with the slide cover 2 is removed, and the image sensor 5 is in a usable state. The detection switch 9 is pressed, and the power supply driving of the camera itself and signal processing by imaging are turned on.
[0025]
Also, since the output of the speaker 7 is stopped in this state, the display unit 11 informs the user to that effect, for example, “* There is no output from the speaker at present.” As a result, the user is not mistaken for a malfunction. Furthermore, the user can perform voice communication when using the optimal camera by providing a display prompting the use of the earphone microphone, for example, “If you need sound, please use the earphone microphone.” I understand that.
[0026]
Furthermore, it is possible to control the on / off of the earphone microphone circuit according to the detection result of the detecting means, so that the earphone microphone can be used when necessary, and the consumption caused by leakage or the like when the earphone microphone is unnecessary. Power can be suppressed.
[0027]
FIGS. 3A and 3B are diagrams for explaining the slide cover 2. FIG. 3A is a view from the front, and FIG. 3B is a view from the top.
[0028]
The slide cover 2 is provided with a rail-like hook 3, and the hook is slidably fitted to a hook receiving portion provided in the main body 1.
[0029]
According to the present invention, a mobile phone terminal with a built-in camera is effective for the arrangement of the camera and the display unit, and can be made compact without being enlarged.
[0030]
In addition, when the camera is not used, the camera is in a state of being stored, and the lens can be prevented from being stained or damaged when the phone is used or carried. . In that case, since the signal processing unit and camera driving of the camera can be stopped, power consumption can be suppressed, so that the opportunity for charging is reduced and the mobile terminal can be easily carried.
[0031]
Furthermore, when using the camera, simply move the slide cover and expose the camera to automatically turn on the signal processing unit and camera drive functions necessary for the camera, and use the camera with simple operations. It is a structure that can.
[0032]
In addition, when the slide cover is moved to a non-driven position, the sound reporting hole of the speaker in the receiver and the through hole in the slide cover almost overlap each other, so that during normal calls, the speaker Sound is reported smoothly.
[0033]
Furthermore, since the state of the slide cover can be detected and information necessary at that time can be notified to the user, the operation is not disrupted.
[0034]
【The invention's effect】
The present invention can provide a mobile phone terminal in which a camera and a display unit are arranged without increasing the size with a simple structure.
