Description

  The present invention relates to a mobile phone having a photographing function.

  In recent years, mobile phones have become widespread, but their shapes are roughly classified into three types: straight type, flip type, and clamshell type. Above all, the clamshell type can be miniaturized by folding, so the needs are higher than the other two types.

  Recently, a mobile phone having a liquid crystal sub-display on the back of the liquid crystal display or a camera function has been proposed.

  FIG. 10 is a perspective view showing an external appearance of a conventional clamshell type camera-equipped mobile phone 100 in an opened state. The mobile phone 100 includes a first housing 101 and a second housing 102. The first housing 101 and the second housing 102 are connected via a hinge 103, and angular displacement is performed about the hinge 103 as an axis. It can be folded by moving freely. As shown in FIG. 10, the mobile phone 100 includes a first display unit 104 in a first housing 101. The first display unit 104 is disposed so as to be located on the inner side when the mobile phone 100 is folded. The first display unit 104 (main display) is realized by a liquid crystal display, an EL display, or the like, and displays an image based on image data sent via a first display driver unit provided in the housing. An antenna unit 105 and a vertically movable helical unit 106 are provided on the back surface of the first housing 101, and a second shutter button 107 having a camera function is provided on a side surface of the first housing 101. The first display unit 104 includes a first speaker 108 that is used during a call.

  The open / close detection unit 109 is a detection unit that detects whether or not the mobile phone 100 is folded. A small protrusion 109 a is formed near the hinge 103 at the bottom of the first housing 101, and a small hole 109 b is formed near the hinge 103 at the top of the second housing 102. A detection switch (not shown) is provided inside the hole 109b, and the open / close detection unit 109 includes a protrusion 109a, a hole 109b, and a switch. When the cellular phone 100 is folded, the protrusion 109a of the first casing 101 enters the hole 109b of the second casing 102, a detection switch (not shown) is activated, and the cellular phone 100 is controlled by a control unit provided in the casing. Judge that it is folded.

  Next, the second casing 102 of the conventional mobile phone 100 will be described. The input button unit 110 includes a key for inputting numbers and characters. The function button unit 111 is a group of buttons for performing various settings / functions switching in the cellular phone, and includes a power button 112 for switching power ON / OFF, a first shutter button 113 for a camera function to be described later, a mail function and guidance.

  FIG. 11 is a perspective view showing the appearance of the mobile phone 100 shown in FIG. 10 from the back side. The back surface of the first housing 101 includes a second display unit 120, a camera unit 121, a light unit 122, and the antenna unit 105 already described.

  The second display unit 120 is disposed so as to be located outside when the mobile phone 100 is folded. The second display unit 120 (sub-display) is realized by a liquid crystal display, an EL display, or the like, and displays an image based on image data sent through a second display driver unit provided in the housing.

  The camera unit 121 includes an imaging lens, an imaging device such as a charge coupled device (CCD) image sensor or a complementary metal oxide semiconductor (CMOS) image sensor, and RGB color filters. The camera unit 2 converts the light reflected by the subject and incident on the imaging lens into RGB three-color light through a color filter, and converts the RGB three-color light to the image sensor. As shown in FIG. 11, the camera unit 121 is provided so as to be located outside when the mobile phone 100 is folded.

  The light unit 122 is used as an auxiliary light source when the camera unit 121 captures an image. In general, there are many that use a xenon tube, but recently, there is also an auxiliary light source that emits white light by simultaneously emitting RGB LEDs.

  The back surface of the second housing includes a battery portion 123 for storing a battery and a second speaker 124 for sounding a ringtone.

  FIG. 12 shows an external perspective view of the cellular phone 100 in a folded state, and FIG. 13 is an external side view of the cellular phone 100 in a folded state.

  A method of using the camera using the conventional mobile phone 100 will be described with reference to FIG. FIG. 14A shows a general usage method when a photographer photographs a subject. The cellular phone 100 is opened, the camera unit 121 is directed to the subject, and the photographer uses the first display unit 104 as a viewfinder. FIG. 14B shows a general usage method when the photographer photographs the photographer himself. In this case, the photographer can take a picture while confirming the photographed image by using the second display unit 120 as a viewfinder. In general mobile phones, when displaying on the second display unit 120, in order to eliminate the uncomfortable feeling at the time of screen confirmation, the image is often reversed left and right and displayed like a mirror. In FIG. 14A, either the first shutter button 113 or the second shutter button 107 provided on the side surface of the first housing 101 can be used as the shutter button. In FIG. 14B, shooting is performed using the second shutter button 107 in a state in which the mobile phone 100 is folded, but it is also possible to take a picture in an opened state. In that case, the second shutter button 107 disposed on the side surface of the first housing 101 may be used.

  Many problems remain in the clamshell type camera-equipped mobile phone including the two display means as described above.

  The first problem is the problem of changeover. In the case of a clamshell type cellular phone, the cellular phone is used with the helical portion 106 facing upward as shown in FIGS. 10 and 12 when opened and folded. Therefore, for example, as shown in FIG. 14, the user closes the cellular phone 100 and shoots the user himself (FIG. 14 (b)) and then shoots another subject (FIG. 14 (a)). When various image settings are performed using one display unit 104, the mobile phone 100 must be opened after the mobile phone 100 is once changed in a direction rotated 180 degrees up and down.

  Similarly, when the cellular phone 100 is opened and used after viewing the incoming mail or call display or time display displayed on the second display unit 120, the cellular phone 100 is similarly changed to a direction rotated 180 degrees up and down. After that, the mobile phone 100 must be opened.

  Conversely, even when the portable phone 100 is opened to closed, the portable phone 100 must be held in the opposite direction after being folded. The operation of changing the mobile phone and using it is troublesome for the user.

  The second problem is that the antenna unit 105 provided on the back surface of the first housing 101 occupies a large space. Even when the cellular phone is closed, the size of the second display section 120 on the back side is increasing so that more information can be displayed to the user. However, as shown in FIG. 11 or FIG. Since the antenna unit 105 occupies a large space on the back surface of the first housing 101, the degree of freedom of arrangement of the second display unit 120 sub-display is limited, and a large so-called sub-display can be arranged. Impossible.

  The third problem also relates to the antenna. Since the antenna unit 105 is formed in a convex shape on the back surface of the first housing 101, the antenna unit 105 is used when the user operates the button with a finger even if a shutter button or a sub-display operation button is installed on the back surface. Is a problem that makes it difficult to perform comfortable operations.

  The fourth problem is a problem related to miniaturization of the mobile phone. The user needs to reduce the size of the mobile phone. In the case of the camera-equipped mobile phone 100, since the camera unit 121 is composed of a lens and a CCD, a certain thickness is required. When arranged at the tip of the first casing 101, the tip requires the thickness of the camera part, so the tip cannot be thinned. On the other hand, when the camera is arranged on the hinge 103 side, the field of view of the lens may be blocked by the user's hand when shooting with folding, which is not very practical.

  The fifth problem relates to camera shake. When the camera unit is arranged at the tip of the first housing 101, the camera unit is located at a position away from the second housing 102 having the mobile phone when the user takes a picture with the mobile phone opened. Therefore, it is most susceptible to user shake. On the other hand, when the camera is arranged on the hinge part side, when the camera is folded and photographed as described above in the fourth problem, the field of view of the lens may be blocked by the user's hand, which is not very practical.

When the opening / closing detection unit 49 detects that the cellular phone 1 is folded, the control unit 40 validates the input of the second shutter button 23. When the opening / closing detection unit 49 detects that the mobile phone 1 is open, the control unit 40 validates the input of the first shutter button 10 and invalidates the input of the second shutter button 23. In order to invalidate the input of the first and second shutter buttons 10 and 23, for example, the first and second shutter buttons 10 and 23 are fixed so that the user cannot operate the first and second shutter buttons 10 and 23. 23, the control unit 40 does not output the instruction signal from the first and second shutter buttons 10 and 23 to the control unit 40, and the control unit 40 instructs the first and second shutter buttons 10 and 23 to output the instruction signal. It can be realized by a method such as not processing.

  As described above, since the camera unit 21 is provided on the outside when the mobile phone 1 is folded, when the subject other than the user of the mobile phone 1 is imaged, the user opens the mobile phone 1. Thus, the camera unit 21 is imaged toward the object side opposite to the user. In this state, the opening / closing detection unit 49 detects that the mobile phone 1 is open, and the instruction from the first shutter button 10 becomes valid. The user operates the first shutter button 10 disposed on the same side as the first display unit 5 while looking at the first display unit 5 that is a finder.

  On the other hand, when the user himself / herself is imaged as a subject, in the embodiment of the present invention, it is possible to image the camera unit 21 toward the user side while the user folds the mobile phone 1. In this state, the open / close detection unit 49 detects that the cellular phone 1 is folded, and the instruction from the second shutter button 23 is valid.

Therefore, the user can input while looking at the first or second shutter button 10, 23, and the operability is improved.

  In general, since the shutter button located on the opposite side of the display unit used as a viewfinder is difficult to see from the user, it is erroneous when the user grips the mobile phone 1 or performs an operation other than the shutter button input. May be entered. In the embodiment of the present invention, since the instruction from the second shutter button 23 located on the opposite side of the first display unit 5 used as a viewfinder is invalidated simply by opening the mobile phone 1, an erroneous operation by the user is prevented. can do.

  Note that when it is detected that the mobile phone 1 is open, the input of the second shutter button 23 may be enabled without being disabled. In this case, the user can operate both the first and second shutter buttons 10 and 23. Moreover, since the 1st shutter button 10 is arrange | positioned inside when folded, a user cannot operate when the mobile telephone 1 is folded. Therefore, the input of the first shutter button 10 when the open / close detection unit 49 detects that the cellular phone 1 is folded may be invalid or valid.

The control of the first and second backlights 45 and 46 will be described.
The control unit 40 switches on and off of the first and second backlights 45 and 46 based on the detection result of the open / close detection unit 49. When the open / close detection unit 49 detects that the mobile phone 1 is folded, the control unit 40 turns on the second backlight 46 and increases the luminance of the second display unit 20. When the open / close detection unit 49 detects that the mobile phone 1 is open, the control unit 40 turns on the first backlight 45 and increases the luminance of the first display unit 5.

  As described above, when the user images the subject other than the user himself / herself, the first display unit 5 is used as a viewfinder, and the image data captured from the camera unit 21 is displayed on the first display unit 5. At this time, the first backlight 45 is turned on, and the luminance of the first display unit 5 is increased.

  On the other hand, when the user images the subject as the user himself / herself, the second display unit 20 is used as a viewfinder, and the image data captured from the camera unit 21 is displayed on the second display unit 20. At this time, the second backlight 46 is turned on, and the brightness of the second display unit 20 is increased.

  Thus, when the cellular phone 1 is folded or opened, the backlight for supplying light to the display unit used as a viewfinder is turned on, so that the displayed image is easy to see and visibility is improved.

  FIG. 9 is a flowchart showing the imaging process of the mobile phone 1. In particular, a description will be given of rotating the captured image by 180 degrees when the cellular phone 1 is folded and photographed. Note that the mobile phone 1 can be set to a so-called imaging mode, in which the cellular phone 1 can be imaged by a predetermined operation from a folded state or an opened state.

  First, in step S <b> 1, the control unit 40 determines whether or not the mobile phone 1 is folded based on the detection result of the open / close detection unit 49. If it is opened without being folded, the process proceeds to step S2, and if it is folded, the process proceeds to step S8. In step S2, the first backlight 45 is turned on. In step S3, the image data captured from the imaging unit 2 is displayed on the first display unit 5, and the process proceeds to step S4.

  In step S <b> 4, the control unit 40 determines whether or not the mobile phone 1 is folded based on the detection result of the open / close detection unit 49. If it is open, the process proceeds to step S5. If it is folded, the lighting of the first backlight 45 and the image display on the first display unit 5 are stopped, and the process proceeds to step S8.

  In step S5, the control unit 40 invalidates the input of the second shutter button 23 and detects whether or not the first shutter button 10 has been pressed. If it has been pressed, the process proceeds to step S6, and if not, the process proceeds to step S7. In step S6, the image data temporarily stored in the first memory 42 is stored in the second memory 48, and the process proceeds to step S7. In step S7, the control unit 40 determines whether or not a predetermined operation for ending the imaging mode has been performed by the user. If the operation has been performed, the process ends. If not, the process returns to step S4. When the imaging mode ends, a predetermined standby screen or the like is displayed on the first and second display units 5 and 20.

  If it is determined in step S1 that the mobile phone 1 is folded by the control unit 40, the process proceeds to step S8, and the second backlight 46 is turned on. In step S9, the image data captured from the camera unit 21 is displayed on the second display unit 20, and the process proceeds to step S10.

  In step S <b> 10, the control unit 40 determines whether the mobile phone 1 is folded based on the detection result of the open / close detection unit 49. If it is open, the lighting of the second backlight 46 and the image display on the second display unit 20 are stopped, and the process proceeds to step S2, and if folded, the process proceeds to step S11.

  In step S11, the control unit 40 detects whether or not the second shutter button 23 has been pressed. If it is pressed, the process proceeds to step S12. If not, the process proceeds to step S13. In step S12, the image data temporarily stored in the first memory 42 rotated by 180 degrees is stored in the second memory 48, and the process proceeds to step S13.

  This is because the up-down direction of the camera unit 21 is reversed between the opened state and the folded state of the mobile phone 1, and in the folded state, the second memory 48 is rotated after image data is rotated 180 degrees during shooting. By storing the image data, the image data is prevented from being turned upside down when the image data is displayed on either the first or second display unit 5 or 20 later. In step S13, the control unit 40 determines whether or not a predetermined operation for ending the imaging mode has been performed by the user. If the operation has been performed, the process ends. If not, the process returns to step S10. When the imaging mode ends, a predetermined standby screen or the like is displayed on the first and second display units 5 and 20.

  As described above, since the display unit used as the finder at the time of imaging is appropriately switched by detecting the opening / closing of the mobile phone 1, the user does not need to perform a button operation for switching. This saves time and improves operability and convenience. In addition, when the opening / closing of the cellular phone 1 is detected, the shutter button on the same side as the display unit serving as the finder becomes valid, so that it is possible to input the shutter button reliably while looking at the finder. Improves. In addition, since the input of the shutter button on the opposite side to the display unit serving as a finder is invalid, it is possible to prevent an erroneous operation such as pressing the shutter button by mistake. Further, when the opening / closing of the mobile phone 1 is detected, the backlight of the display unit serving as a finder is turned on, so that the image is easy to see and the visibility is improved. Further, when the image is taken in a folded state, the image data is rotated 180 degrees and stored in the second memory 48 when the image data is stored, so that when the stored image data is displayed later, It is possible to prevent the image from being displayed upside down.
