The first embodiment of the display device of the portable information communication device of the present invention will be described below. FIG. 1 is an outline view of the invention. 1 is a main body of a portable information communication device, 2 is a color liquid crystal display unit for displaying images and characters using liquid crystal, 3 is a camera head for guiding visible light through a lens to an image sensor, and 4 is an audio signal. A sound generation part (hereinafter referred to as a speaker) for converting to sound, 5 is a sound receiving part (hereinafter referred to as a microphone) for converting sound or sound into an electrical signal, and 6 is a plurality of keys for various operation instructions displayed on the display screen. , A touch switch that can perform each instruction by touching 6a to 6j. 6sw is a mechanical push switch, and 7 is an antenna for transmitting and receiving radio waves. The operation will be described with reference to FIG. When the switch 6sw is pressed, power is supplied to the portable information communication device 1, and the position of the characters and touch keys 6a to 6j and the display direction of the keys appear as a vertically long display on the color liquid crystal display unit 2. Next, the touch keys 6a to 6j shown in the figure are selected, the dial number is designated, the other party is called, and a call is started. Then, when displaying an image from the other party side or the own side during a call, the display direction of the portable information communication device 1 is displayed vertically as shown in FIG. The display contents can be checked while holding 1 in the hand.

  Next, when the touch keys 6a to 6j are selected and the camera video shooting is instructed, the portable information communication device 1 displays the video of the camera head 3 in the landscape orientation on the color liquid crystal display unit 2 as shown in FIG. . At this time, the positions of the touch keys 6a to 6j are also displayed horizontally, the direction of the characters is also displayed horizontally, and the key position is moved to a position that is easy to operate when the portable information communication device 1 is held horizontally. The (Only 6j is shown in the figure). Then, the operator lays down the portable information communication device 1 and holds the vicinity of the camera head 3 with the right hand and then the vicinity of the microphone 5 with the left hand. That is, because the camera is held with both hands, the shake of the camera head 3 can be reduced as compared with the holding with one hand, so that the photographing can be stably performed. Furthermore, because the portable information communication device 1 has a horizontally long display in which the liquid crystal display is widened in the vertically long direction, it becomes very easy to see, and the image can be easily taken. As described above, the display screen of the portable information communication device 1 is displayed in a vertically long display in the vertical direction, so that camera shooting can be performed stably and shooting is easy. Note that, when the portable information communication device 1 is turned sideways, the image of the camera-captured landscape is changed from the vertical display to the horizontal display. Therefore, when it is converted to the horizontal display, the display returns to the vertical display and the image is inverted. In order to prevent this, an on / off key for changing the display direction is provided on the touch key, the conversion to the landscape display is stopped, and the image from the camera is displayed as it is.

  Next, FIG. 3 shows another embodiment of the present invention. Reference numeral 9 denotes a mechanical switch (9a to 9j and 9sw), and an operation instruction or a dial number is input by pressing the switch. This switch is provided in place of the touch sensor 6 in the color liquid crystal display unit 2 in FIGS. 1 and 2 and requires a dedicated place thereof, and the shape becomes vertically long by that length, so that portability is impaired. However, it is possible to avoid oil stains on the fingers due to touch operations on the display screen.

  FIG. 4 is a block diagram of the first embodiment of the present invention shown in FIGS. A photoelectric conversion signal 51 is obtained from a camera head 50 including a light receiving lens, a solid-state image sensor, a solid-state image sensor drive circuit, and the like, and is input to the camera circuit 52. The camera circuit 52 includes a camera signal processing circuit, a synchronization signal generation circuit, and the like, and generates a video signal 53 in a television signal format from the light conversion signal 51. The video signal 53 is output in the vertically long display direction and input to the image arrangement conversion circuit 54. The image arrangement conversion circuit 54 includes a RAM (Random Access Memory) 55, a write address generation circuit 56, a read address generation circuit 57, and the like. The video signal 53 is stored in the RAM 55 of the image arrangement conversion circuit 54. Here, in synchronization with the synchronization signal 58 from the camera circuit 52, the video signal 53 is stored in a predetermined memory address on the RAM 55 by the memory address signal 59 output from the write address generation circuit 56 in a predetermined order. The The video signal 53 once stored in the RAM 55 is read from the RAM 55 by the memory address signal 60 output from the read address generation circuit 57 synchronized with the synchronization signal 58, but the address generation of the read address generation circuit 57 is performed. The order is stored in advance in ROM 1 (Lead Only Memory, not shown), and read addresses are sequentially output from ROM 1 by a counter synchronized with a synchronization signal 58. Here, the scanning direction of the color liquid crystal display unit 2 in the landscape display is the horizontal direction from the upper left end to the right end toward the landscape display screen, and the scanning direction in the portrait display is the lower left end toward the portrait display screen. The vertical direction from the top to the top will be described below. In order to convert the portrait display to the landscape display, pixel reading is performed in the row direction from the upper left end toward the portrait display screen, and the display is performed by horizontal scanning in the landscape display direction. For this purpose, first, a vertically long video signal is stored in the RAM 55. The read address is read in order from the first address of the row n corresponding to the upper left end of the memory position written by the previous write address generation circuit 56 toward the vertically long display screen. Will do. When the row ends, the read address generation circuit 56 shifts to the first address of the next row n + 1 so that the same reading is performed. As a result, the display direction can be converted from portrait display to landscape display. That is, if the video signal 53 for one field of the television signal is stored in the RAM 55 and read out by the above-described method in the next field period, the video signal 61 of the horizontally long display can be obtained from the vertically long display. Further, in order to obtain a continuous television signal, a RAM 55 for storing video signals 53 for two fields is provided, and a signal written one field before is read simultaneously with writing a video signal of a certain field. What is necessary is just to comprise.

  Next, the video signal 61 converted into the landscape display is input to the terminal 64. On the other hand, the vertically long video signal 53 of the camera circuit 52 is input to the terminal 62. The signals of the terminal 62 and the terminal 64 are controlled by the output signal 65 of the control circuit 80 which receives the touch keys 6a to 6j and the mechanical switch 6sw signal, the reception signal of the communication device 1 and the like and generates various control signals. The switch 73 is switched. In response to the camera shooting instruction from the touch key, the switch 73 is switched to the terminal 64 side of the video signal 61 converted into the landscape display. Further, in the call instruction from the touch key, the terminal 62 of the video signal 53 of the vertically long display is switched. The switched signal 67 stores the information indicating the position of the touch key and its name, and the status of the device in the form of characters and graphics, and outputs the signal 70 from the character graphic generation circuit 69 which outputs them as an adder. 68 and displayed on the color liquid crystal display unit 2. That is, the portrait display including the character signal 70 in the landscape display obtained by converting the portrait display from the camera by the image arrangement conversion circuit 54 is performed. In addition, the portrait display including the character signal 70 is performed on the portrait display from the camera during a call. The output signal 67 is also input to the modulation circuit 81 to transmit a vertically or horizontally long image. Here, the horizontally long display means is the image arrangement converting circuit 54. However, if the display at the time of camera image shooting is already in the horizontally long display, there is no need to convert it. In this case, the changeover switch 73 and the control are controlled. The control circuit 80 (for example, using the instruction signal by the above-described display direction conversion on / off key) is necessary and included.

  If the portrait display during camera shooting is the same as the image sent from the other party, the image on the other party, that is, the switch 73 used in the landscape display is used for controlling the display. The control circuit 80 or the like can be used together, and this also becomes a vertically long display means.

  Next, the output signal 90 of the control circuit 80 is input to one side of the modulation circuit 81. The modulation circuit 81 modulates the microphone 5 or the vertically long video signal, and performs output on / off control. The other output signal 92 of the control circuit 80 is input to a carrier synthesizer 93 that obtains a predetermined oscillation or reception frequency from the reference signal, and the circuit 80 is turned on / off. The other output signal 91 of the modulation circuit 81 is input to the oscillation circuit 82 and modulates the carrier frequency signal 93 of the oscillation circuit 82. The oscillation circuit 82 amplifies the modulation power. The signal is guided to the antenna 7 via the service device 93, oscillates a radio wave, and information is transmitted to the other side. At this time, since transmission and reception timings are separated, transmission and reception are not mixed. Therefore, the transmitted radio wave on the other side becomes a signal 96 via the antenna 7 and the duplexer 83 and is input to the receiving unit 85. The receiving unit 85 obtains a demodulated signal 98 of the received signal from the received signal and the output signal 95 of the carrier wave synthesizer 94. The signal 98 is input to a demodulation circuit 86 that demodulates audio, video signals, and character signals. The output audio signal 33 of the demodulating circuit 86 is supplied to the speaker 4 and converted into audio, and the output video signal 34 is obtained through the terminal 63 and the switch 73 to obtain the signal 67, which is input to the color liquid crystal display unit 2 and displayed vertically. Is done. The other output signal 99 of the demodulation circuit 86 is input to the control circuit 80, and various operation timings at the time of reception are controlled. Further, the output synchronization signal 35 of the demodulation circuit 86 is input to the color liquid crystal display unit 2 via the terminal 76 and the switch 74, and the synchronization timing is obtained to obtain a stable image.

  Next, a second embodiment of the present invention will be described in detail with reference to FIG. 4a is a speaker, 5a is a microphone, and 21 is the gravity direction and the inclination of the portable information communication device 1 with respect to the direction of gravity due to the movement of the liquid in the direction of gravity and the property of staying stable in that direction. Gravitational direction detectors 11, 25, and 74 are switches for switching signals. Next, the operation will be described. The gravity direction detector 21 is configured integrally with the color liquid crystal display unit 2, and four detection signals 22 obtained from the display position of the color liquid crystal display unit 2 with reference to the direction of gravity are obtained as shown in Table 1.

The detection signal 22 is input to the control circuit 80. The control circuit 80 determines the content of the detection signal 22. For example, when the portable information communication device 1 is carried, if the display position is in the portrait direction and the image is reversed (the carrying direction is opposite) with respect to the operator, the detection signal 22
Outputs a digital signal 1011 as shown in Table 1. This is determined by the control circuit 80. Then, in the case of a call instruction, the changeover switches 11, 25, 74 and the character graphic generation circuit 69 are controlled by the output signals 27, 13 and 14 of the control circuit 80 so that the display position is displayed in the vertical direction. To do. This operation is described in further detail below. A signal 28 obtained by switching the video signal 34 (for example, landscape display) received by the demodulation circuit 86 and the camera photographing signal 53 (portrait display) of the camera circuit 52 by the selector switch 25 is input to the terminal 29 and the image array conversion circuit 54. Is done. The terminal 29 receives the received video signal 34 and the camera shooting signal 53 via the switch 11 and displays the received (call) or camera shot video in the original display direction. .

  On the other hand, the image arrangement conversion circuit 54 converts the display direction from the portrait display to the landscape display by the ROM 1 of the write address generation circuit 56, the RAM 55, and the read address generation circuit 57 described above. However, in order to convert from the opposite landscape to the portrait display, the read address of the RAM 55 is stored in advance in a new ROM 2 (not shown), and the read address is sequentially read from the ROM 2 by a counter synchronized with the synchronization signal 58. Instruct. Therefore, the screen conversion method from the horizontally long display screen may be read upward in the column starting from the bottom left pixel toward the horizontally long display screen. Therefore, the read address in the ROM 55 starts from the first m address of the row corresponding to the bottom left end toward the horizontally long display screen of the memory address written in the horizontally long direction by the previous write address generating circuit 56, The addresses are sequentially read upward. When the column is completed, the read operation is performed by moving to the m + 1 address in the same row. Due to the vertical conversion at this time, image loss due to the difference in the number of vertical and horizontal pixels occurs, but if the part is set to move to the peripheral part of the full screen, the peripheral part image has few important parts, Since there is almost no problem, the previous origin read address m may be changed to the inside of the screen. As a result, a video signal 61 obtained by converting the horizontally long display data written in the RAM 55 into the vertically long display is obtained. Here, the vertically long display means does not need to convert the image arrangement conversion circuit 54 or if the display at the time of the call is already in the vertically long display. In this case, the changeover switch 11 and the control circuit for controlling it are used. 80 etc. are required, and these are also included. The addressing of the ROM 1 and ROM 2 in the address reading operation is performed by a counter using a synchronization signal. This is constituted by a known up / down counter, and the counting direction is increased by the output signal 15 of the control circuit 80. By switching with down, it is possible to switch to the same or reverse order of generation of read addresses stored in ROM1 and ROM2 in advance. Thereby, an upright display or an inverted display is further performed on the display converted into the portrait display or the landscape display. Further, the output signal of the up / down counter is directly connected to the RAM 55 without going through the ROM 1 and ROM 2 for the address reading operation, and similarly, the count direction is switched between up and down by the output signal 15 of the control circuit 80, so that the RAM 55 The read address is switched to the read address that is the same as or reverse to the write address, and the display direction written in the RAM 55 and the upright or inverted display can be obtained. These operation instructions are given by the control circuit 80. For example, a discrimination signal for displaying a portrait or landscape display of an image sent from a partner (data A is 1 for portrait, 0 for landscape), or a portable information communication device 1 itself for portrait or landscape discrimination (data B is data B). 1 is vertically long and 0 is horizontally long) and the information of the detection signal 22 of the gravity direction detector 21 is judged by the control circuit 80 (the logic circuit of the digital signal is configured). The upright display is performed by controlling the changeover switches 11 and 25. In this way, a configuration in which the upright display means, the horizontally long display means, and the counter for instructing the forward and reverse directions of the address reading such as the RAM 55 are operated to display upright is referred to as upright display means. The specific operations are shown in Tables 2 and 3.

  The table shows the operation of each switch, the reading counter of the RAM 55, and the counters of the ROM 1 and 2 when the display direction is portrait or landscape when the phone call is taken or when the camera is photographed. Table 2 shows each operation for setting the display direction to the vertically long direction during a call, to the horizontally long direction when shooting with the camera, and to display upright. Table 3 shows each operation for controlling the display direction so as to match the display direction of the current display position on the side of the communication device 1 and displaying the image upright. At this time, the reception synchronization signal 35 and the synchronization signal 58 from the camera are switched by the switch 74 in conjunction with the switch 25, and are supplied to the writing / reading address generation circuit 57 and the color liquid crystal display unit 2 to be connected to each circuit. Synchronization is obtained. In this way, when the operator arbitrarily holds the portable information communication device 1, the state is detected by the gravity direction detector 21, the received signal and display content are judged by the control circuit 80, and each circuit And the liquid crystal display direction can be automatically corrected to the upright direction, and the operation of changing the portable information communication device 1 can be omitted. At this time, since the camera position can be detected by the gravity direction detector 21, when the portable information communication device 1 is moved from vertical to horizontal or vice versa, the display direction is switched from the detection signal. The liquid crystal display direction can be automatically corrected to the upright direction. Tables 2 and 3 do not display the case where the camera position is turned upside down, but this can also be displayed upright by using the method described above.

  Next, a detailed configuration of the gravity direction detector 21 is shown in FIG. A conductive liquid G (eg, saline solution) is input inside an approximately diamond-shaped outer shape E, and a common electrode F is arranged on one side of the inside. Further, four electrodes A1, B1, C1, and D1 are arranged at the four ends of the other side of the outer shape E, and conduction with the electrode F is detected via the conductive liquid G. For example, when the color liquid crystal display unit 2 is positioned in the vertical direction as shown in the figure, all the electrodes other than the electrode A1 are electrically connected to the electrode F through the conductive liquid G, and a signal is transmitted to the control circuit 80. As shown in Table 1, it can be detected that the liquid crystal display is vertically long and upright with respect to the operator. That is, when the portable information communication device 1 is arbitrarily held, the conductive liquid G moves in the direction of gravity, so that an electrode in a non-conductive state is obtained, and by detecting it, the current liquid crystal display surface is displayed. The horizontal or vertical position can be detected. Moreover, it can determine with the gravity direction the other side of the electrode position of the place which does not conduct. Furthermore, if another is prepared and arranged in a direction perpendicular to the figure, the horizontal or vertical direction before and after the surface of the liquid crystal can be detected, and a fine position can be detected. The outer shape is not limited to a rhombus, and may be a circle or a polygon. Moreover, Koji Tanikoshi of the conventional tilt sensor Author: Name; Talk of sensor understood by graphic: June 15, 1995 issue: Configuration to detect capacitance change and pendulum position described in p146-p147, etc. Although it may be used, there is an advantage that the configuration is simpler than that. Further, since the gravity direction detector 21 uses a liquid in the same manner as the color liquid crystal display and constitutes an electrode by sandwiching the liquid, it can be manufactured by the same method, so it is integrated with the color liquid crystal display. Manufacturing has the advantage of reducing costs.

  In FIG. 5, 4 a is a second speaker that converts an audio signal into audio, 5 a is a second microphone that converts audio into an electric signal, and the speaker 4 a is arranged next to the microphone 5, and a demodulation circuit 86. Connected to the output signal 36. The microphone 5 a is arranged next to the speaker 4 and is input to the modulation circuit 81 via the signal 37. When the operator carries the portable information communication device 1, the vertical direction of the color liquid crystal display unit 2 of the portable information communication device 1 is detected by the detection signal 22 of the gravity direction detector 21, and the gravity signal is detected by the detection signal. Switching is performed in the modulation circuit 81 so that the microphone 5 or the microphone 5a on the direction side operates. On the contrary, switching is performed inside the demodulation circuit 86 so that the speaker 4 or the speaker 4a on the side opposite to the direction of gravity operates. That is, the microphone on the gravity direction side is operated, and the speaker on the opposite side to the gravity direction is always operated. This is referred to as receiving / sounding switching means. Thereby, the difference between the microphone and the speaker position is eliminated equivalently, and by using together with the erecting display means in the color liquid crystal display direction, even if the operator initially holds the portable information communication device 1, You can talk, display and operate in the same way as the right direction, so you don't have to change it and you can use it easily. Note that when the portable information communication device 1 has a horizontal inclination, the operations in front of the microphone and the speaker are held so as not to respond to the sudden change operation.

  Further, the positions of the touch keys 6a to 6j and the names thereof are displayed by the output signal 13 of the control circuit 80 in accordance with the display directions of the color liquid crystal display unit 2 and the positions of the characters and figures when they are upright or inverted. This is performed by controlling the stored character graphic generation circuit 69 (this is a character graphic generation means), and the detection signal 22 of the gravity direction detector 21 is judged by the control circuit 80 to obtain the positional relationship between the display direction and the operator. Therefore, the positions of the touch keys 6a to 6j and their names are moved to positions where the operator can easily operate the portable information communication device 1 in that state. This operation is performed by the control circuit 80 and the character generation circuit 69 and serves as a position moving unit. For example, when the display is horizontally long and the camera head 3 is on the right side, the positions of the touch keys 6a to 6j from the character generation circuit 69 are displayed. Is read out and displayed in the memory located near the finger of the lower holder of the display, and while holding the portable information communication device 1, the operation instruction figure and characters are made as close as possible to the operator. Improve usability.

  Further, since the portable information communication device 1 can be used only for reception by completely stopping transmission data in addition to a call, in that case, the mode is designated by the touch keys 6a to 6j, and this is designated as a control circuit. 80, the received video signal 34 of the vertically long display at the time of reception is input to the image arrangement conversion circuit 54, and is converted into the horizontally long display by the horizontally long display means. Thereby, it is a landscape display with an expanded display screen, and there is an advantage that it is easy to see.

  The gravity direction detector 21 detects the position where the portable information communication device 1 is placed with respect to the direction of gravity. Further, since the operator generally has a head on the side opposite to the direction of gravity, the direction of gravity indicates the position of the operator. Therefore, if the detection position is in the vicinity of the vertical direction, the display direction is set to be vertically long using the vertically long display means, and if it is near the horizontal direction, the display direction is set to be horizontally long using the horizontally long display means. Furthermore, since the erecting display means always stands upright with respect to the operator, there is an advantage that the operator can easily see the display and the operation of changing the portable information communication device 1 can be eliminated. Further, on the contrary, if an operation of changing the portable information communication device 1 is performed, there is an advantage that the display direction can be changed in response to the operation. Further, since the gravity direction detector 21 is provided inside the portable information communication device 1, there is an advantage that the position of the operator is not limited.

  According to the present embodiment, since the length direction of the color liquid crystal display surface is set to the vertical direction of the portable information communication device 1, the display area is improved, and the landscape display is used when photographing with the camera or when receiving only, so that it is easy to see. Yes. Therefore, there is an effect that it is easy to set video shooting. Also, when shooting a video, the portable information communication device is horizontally long and is held with both hands, which has the effect of reducing camera shake. In addition, since the portrait display is used during a call, there are effects such as ease of viewing in a call state and ease of operation. Furthermore, since the portrait display and the landscape display are electronically switched, there is an effect of eliminating breakage when carrying and being hard to break.

  In addition, since the color liquid crystal display direction of the portable information communication device 1 can be displayed to the operator so as to be always upright by the gravity direction detector and the upright display means, it is not necessary to correct the possession position. There is an effect that can be made.

  Further, another speaker is arranged next to the microphone, another microphone is arranged next to the speaker, and sound receiving and receiving means for controlling it by a detection signal of the gravity direction detector, and various operation switches are taken in the video display unit, and Even if the portable information communication device 1 is always held by the position switching means for moving the position of the operation key and its name, the microphone is placed on the gravity direction side of the portable information communication device 1 and on the opposite side. Operate the speaker. Then, the operation instruction position and its name are brought close to the operator to facilitate the operation, and the portable information communication device 1 with the display always upright displayed can be called, and the operation to change the position can be omitted. .

  Further, the gravity direction detector 21 indicates the positional relationship between the portable information communication device 1 and the operator, and the color liquid crystal display can be set to a portrait display and a landscape display by the detection signal. By changing the carrying direction of the portable information communication device 1, the person can omit the effect of setting a favorite display direction and the operation of changing the portable information communication device 1.

  Further, since the gravity direction detector detects conduction and non-communication, the configuration is simple, and since it can be detected internally, it does not limit the position of the portable information communication device 1 and is easy to use.

  Furthermore, by configuring the color liquid crystal display unit integrally with the color liquid crystal display unit, the configuration of the liquid crystal display unit can be used and the cost can be reduced.
