Description

  The present invention relates to an electronic device in which an upper housing and a lower housing are connected.

  In recent years, mobile communication terminal devices with a video camera have been used.

  4A and 4B are external views of a general foldable mobile phone of a mobile communication terminal device, FIG. 4A is a front view, and FIG. 4B is a rear view.

  Hereinafter, a conventional mobile phone will be described with reference to the drawings. The foldable mobile phone has a structure in which an upper housing 51 and a lower housing 52 are pivotally connected by a hinge 53 to be opened and closed. Further, a folding switch for detecting the opening / closing is provided inside the casing (not shown).

  A main LCD 104 and a speaker 54 are disposed on the front surface of the upper housing 51, and an antenna 112 is disposed on the top of the upper housing 51.

  A rear LCD 105 and a video camera 103 are disposed on the rear surface of the upper casing 51.

  On the front surface of the lower casing 52, a key 101 such as a numeric keypad, a function key, and a cross key, and a microphone 107 are arranged.

  In this configuration, at the time of moving image shooting, the upper casing 51 is opened and the folding switch is turned OFF to perform shooting and recording. In other words, the operator points the camera 103 at the subject and takes a picture while checking the moving image from the camera 103 on the main LCD 104, and the sound at the time of shooting is input from the microphone 107 to the internal voice memory 10. When the upper casing 51 is closed, the folding switch is turned on and the moving image shooting is finished.

  As another prior art, there is a wireless information device that is not a foldable mobile phone, but has a single LCD, can be opened and closed only by an LCD case that covers the LCD, and includes a camera for shooting moving images. (For example, refer to Patent Document 1).

  In this wireless information device, when the open state is detected by the opening / closing switch of the LCD case, it is determined as the TV phone mode. In the TV phone mode, the input gain of the microphone is increased because the operator's voice is far from being hands-free. In addition, the camera and the single LCD are turned on to shoot a moving image.

JP-A-11-215477 (page 1-20, FIG. 1-33)

  By the way, the above-described conventional apparatus has a drawback in that the battery usage time is shortened because the main LCD or the single LCD having a large current consumption is turned on during moving image shooting.

  In addition, there is a drawback that moving images cannot be taken with the casing closed.

  Therefore, an object of the present invention is to provide an electronic device that provides a moving image shooting mode with a small current consumption and that can be shot even in a compact state with the casing closed.

  In order to achieve the above object, an electronic device according to claim 1 of the present invention is a camera that captures a moving image, an image memory that stores a moving image from the camera, and a first display that displays characters and images. Means and a second display means, and a state detection means for detecting the state of the connected upper casing and lower casing, and in the moving image mode using the camera, When the second display means is designated as a display destination, the display of the first display means is turned off regardless of the state detected by the state detection means, and the camera photographing is performed on the second display means. And a control means for displaying a message indicating that the medium is in progress, or displaying a moving image from the camera or a moving image from the image memory.

  According to the present invention, in an electronic device in which an upper housing and a lower housing are connected, a moving image display destination at the time of moving image shooting is a main LCD with a large current consumption or a rear LCD with a small current consumption. It is possible to reduce current consumption by selecting the rear LCD as the display destination. In addition, moving pictures can be taken even when folded and compact.

1 is a block diagram of a mobile phone showing an embodiment according to the present invention. The operation | movement flowchart of the moving image imaging | photography mode of the mobile telephone shown in FIG. The operation | movement flowchart of the input gain control of the microphone of the mobile telephone shown in FIG. 1 is an external view of a general folding mobile phone.

  1, 2 and 3 show an embodiment in which the present invention is applied to a mobile phone, FIG. 1 is a block diagram of the mobile phone, and FIGS. 2 and 3 are flowcharts in a moving image shooting mode.

  As shown in FIG. 1, the main parts of this cellular phone are a key 1, a control unit 2, a camera 3, a main LCD 4 (first display means), a rear LCD 5 (second display means), an image memory 6, and a microphone. 7, a gain adjustment unit 8, an audio memory 10, a communication unit 11, an antenna 12, and a folding switch 13.

  At the time of moving image shooting, information from the key 1 is input to the control unit 2. Here, when the moving image shooting mode is instructed by the key operation from the key 1, the control unit 2 captures the moving image signal from the camera 3, stores it in the image memory 6, and also stores the moving image in the main LCD 4 or the rear LCD 5. Display an image, etc.

  The control unit 2 captures the audio signal from the microphone 7 via the gain control unit 8. At the time of the capture, the gain control unit 8 uses the gain switching signal 9 from the control unit 2 to input the input gain from the microphone 7. It operates so as to vary the size of the audio signal to be captured. The acquired audio signal is stored in the audio memory 10.

  When transmitting a moving image and an audio signal to a communication partner, the control unit 2 performs encoding and modulation of the moving image and the audio signal, and transmits them from the antenna 12 via the communication unit 11.

  The control unit 2 checks the folding switch 13 to determine whether the upper casing 51 of the folding cellular phone shown in FIG. 4 is open or closed, and controls the capturing of the moving image signal and the audio signal. To do.

  Next, the operation during moving image shooting will be described with reference to the flowchart of FIG. First, the control unit 2 checks the key 1 and enters a moving image shooting mode when a moving image shooting is instructed (step S1). Thereafter, regardless of whether the folding switch 13 is ON or OFF, that is, the upper casing 51 is turned on. Regardless of the open / closed state, the movie shooting mode is continued.

  When the moving image shooting mode is entered, the control unit 2 first performs control relating to capturing of moving images and audio signals. That is, the moving image from the camera 3 is taken into the image memory 6, and the sound signal from the microphone 7 is taken into the sound memory 10 in order to capture sound at the time of shooting (steps S2 and S3).

  Next, the control unit 2 performs control related to display of moving images and the like during the moving image shooting mode. That is, first, the selection operation of the display destination screen designated in advance from the key 1 is checked, and the folding switch 13 is checked (steps S4 and S5).

  In this check, when the main LCD 4 is selected as the display destination and the upper casing 51 is in the open state (folding switch is OFF), the control unit 2 displays a moving image on the main LCD 4 and displays the rear LCD 5. Turn off (step S6, step S7). The moving image can be displayed on the main LCD 4 by directly displaying the moving image from the camera 3 or by displaying the moving image stored in the image memory 6.

  As a result, normal moving image shooting using the main LCD 4 with good resolution can be performed.

  When the main LCD 4 is selected as the display destination in the check in step S4 and the upper casing 51 is in the closed state in the check in step S5, the control unit 2 turns off the display of the main LCD 4 and displays “video” on the rear LCD 5. A message such as “shooting” is displayed (steps S8 and S9). The message displayed on the rear LCD 5 is read and displayed in advance in the internal memory of the control unit 2, and the content of the message is not limited to the above example.

  Here, the message is displayed on the rear LCD 5, but instead of step S9 in FIG. 2, the moving image from the camera 3 is directly displayed on the rear LCD 5, or the moving image stored in the image memory 6 is displayed. You can also. As a result, the operator can take a self-portrait while looking at the camera 3 and the rear LCD 5. Further, although the display of the main LCD is turned off in step S8, the rear LCD can be used even if the display of the main LCD is kept on and the display is performed on the rear LCD in step S9.

  Therefore, according to the present invention, in a foldable mobile phone, even when the upper casing is closed in a compact shape, that is, even when the folding switch is turned on and the apparatus is normally inactive except for the radio unit. Movie shooting using a camera can be performed. In this case, the display of the main LCD 4 that consumes a large amount of current can be turned off, and a message can be displayed on the rear LCD 5 or a moving image captured by the camera can be displayed on the rear LCD 5 to notify the operator.

  When the back LCD 5 is selected as the display destination in the check in step S4, the control unit 2 turns off the display of the main LCD 4 and displays a moving image on the back LCD 5 regardless of the open / closed state of the upper housing 51. (Step S10, Step S11).

  Thereby, it is possible to perform moving image shooting by selecting the rear LCD 5 having a small current consumption and displaying a moving image shot by the camera.

  During the moving image shooting mode, the control unit 2 further performs control related to the input gain of the microphone shown in FIG. That is, when the upper casing 51 is in the open state, the gain switching signal 9 is output so as to set the input gain of the microphone 7 in the gain control unit 7 to a normal set value by the OFF signal of the folding switch 13 (step S13). ). Therefore, when the upper casing 51 is in the open state, the audio signal is processed with a normal input gain. On the other hand, when the upper casing 51 is in the closed state, the gain switching signal 9 is output so as to set the input gain of the microphone 7 in the gain control unit 7 to a set value larger than the normal set value by the ON signal of the folding switch 13. (Step S14).

  That is, when the upper casing 51 is in the closed state, the microphone 7 is sandwiched between the upper casing 51 and the lower casing 52 and is hidden, and the sound is poor. In the present invention, the open / closed state of the upper housing is determined from the ON / OFF signal of the folding switch 13, and when the closed state is determined, the input gain of the gain control unit 8 is set large.

  In this embodiment, the input gain is switched as a fixed value, but the sensitivity may be switched by AGC or the like.
