Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image pickup display device in which a camera and a monitor liquid crystal display element are integrated. 2. Description of the Related Art In a conventional camera-integrated display device, for example, a movie with a liquid crystal TV, a content recorded by a VTR is immediately reproduced on the spot and a liquid crystal television for monitoring (hereinafter referred to as a monitor TV). Or an image from a camera can be directly displayed on a monitor TV for observation. [0003] For this reason, a movie with a liquid crystal TV is widely used, for example, it can be used for research on forms in various sports, and checking of dressing and makeup. The advantage of using a movie with a liquid crystal TV for checking dressing and makeup in this way is that, since the screen is reduced, the user can visually recognize himself / herself more than if he / she sees it in a mirror. [0004] However, such a conventional display device needs to be able to photograph itself. In this case, the orientation of the entire device can be changed, but the display surface of the liquid crystal is not visible. Therefore, it is conceivable to rotate the camera in a direction opposite to that during normal shooting. However, in this case, since the direction of the camera is up / down and left / right, the captured image is similarly up / down and left / right. Accordingly, an object of the present invention is to rotate the camera unit so that the operator himself can be monitored as a subject by the liquid crystal display device, and the image displayed on the monitor can be freely inverted to obtain a desired display. An object of the present invention is to provide an imaging display device that can be in a state. SUMMARY OF THE INVENTION The present invention provides an image pickup means rotatably supported by a main body, a recording means for recording a video signal from the image pickup means, and a display of a video signal from the image pickup means. Liquid crystal display means, a vertical driving means for driving the liquid crystal display means in a vertical direction and a horizontal direction according to a synchronization signal separated from a video signal, and a horizontal driving means; a vertical driving means; A switching unit for reversing the driving direction of the direction driving unit. When the camera section is turned to the operator side to take an image of the operator himself, only the vertical operation direction of the liquid crystal display means is reversed so that the operator has the same correct orientation as in normal shooting. Can be displayed. An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, as shown in FIG.

2 and V3 are applied to the column electrode selection drive circuit 14. As shown in FIG. 3, the column electrode selection drive circuit 14 is provided with a counter 17 for receiving the clock signal CLH from the synchronization control circuit 12 and counting the clock signal CLH. This counter 17 is a so-called up / up counter capable of performing a counting operation in an addition direction (up) or a subtraction direction (down).
This is a down counter. In order to switch the counting direction of the counter 17, a counter changeover switch 18 is provided. The counter changeover switch 18 has terminals 19, 20, 21
An H level voltage is applied to one terminal 20, and the other terminal 21 is grounded to be at an L level. The counter 17 forms an up counter by connecting the terminals 19 and 20 (that is, H level), and forms a down counter by connecting the terminals 19 and 21 (that is, L level). The binary signal output from the counter 17 is supplied to the BCD decoder 22,

It comprises a BCD decoder 25 for outputting a row electrode selection signal Sc, a counter changeover switch 26, and a driving device 27. The counter changeover switch 26 is linked with the rotation of the camera 8. That is, when the camera 8 is facing forward (direction indicated by arrow F), the terminals 28 and 29 are connected to make the counter 24 an up counter, and the camera 8 is facing rearward (direction indicated by arrow B). In this case, the terminals 24 are connected to make the counter 24 a down counter.
The connection state of the counter changeover switch 26 can be released by operating the operation button 31, so that the counter 24 can be set to any of an up counter and a down counter. The VTR unit 4 is formed below the main body 5 and records a color video signal S1 supplied from the camera unit 1 or a TV tuner (not shown) together with an audio signal on a VTR tape (not shown). It is to let. At the time of reproduction, the VTR unit 4 outputs a color video signal S1 to the image display circuit 3 to display the image P on the LCD2. Next, a normal image P and a mirror image PM are displayed on the LCD 2 of the camera-integrated display device by using the camera 8.
Will be described. (1) To Display a Normal Image P As shown in FIG. 4, the camera 8 is pointed at a subject (not shown), and the terminals 19 and 20 of the counter changeover switch 18 are displayed.
To apply an H level voltage to the counter 17 to make the counter 17 an up counter. On the other hand, the counter changeover switch 26 is in a state in which the terminals 28 and 29 are connected because the camera 8 is facing forward (the direction indicated by the arrow F).
The counter 24 is an up counter. When the clock signal CLV is applied to the counter 24 of the row electrode selection drive circuit 15 which is an up counter, the clock signal CLV is counted and the counted value is supplied to the BCD decoder 25 as a binary signal. BC
The D decoder 25 applies the row electrode selection signal Sc to the drive circuit 27 from the first binary signal. Driving circuit 27 selects the row electrodes X ₁ of the first row by the row electrode selection signal Sc applies a driving signal SM. When the clock signal CLH is applied to the counter 17 of the column electrode selection drive circuit 14 as an up counter, the clock signal CLH is counted and the counted value is supplied to the BCD decoder 22 as a binary signal. BCD
The decoder 22 outputs a column electrode selection signal S from the first binary signal.
r is applied to the drive circuit 23. Drive circuit 23 applies a driving signal SM select the column electrodes Y ₁ of the first row by the column electrode selection signal Sr. As a result, the first row electrode X ₁
And a drive signal SM is applied to each of the _first column electrodes Y1 to drive the pixel _E1,1 at the intersection. When the next clock signal CLH is applied to the counter 17 of the column electrode selection drive circuit 14, the counter 17
Is incremented in the addition direction and the second column electrode Y ₂
There pixel E _{1, 2} are selected drive signal SM is applied at the column electrode selection signal Sr is driven. And row electrodes X ₁ of the first row in this manner, which with the driving of the pixel E _{1, j} at the intersection of the respective column electrode Y _j crossing until the n-th column from the first column, increasing direction (column When the clock signal CLV is applied to the counter 24 of the row electrode selection drive circuit 15 after the operation is performed in the direction of increasing the electrode Y (the direction of the arrow YU), the counter 24 increments in the addition direction and then passes through the BCD decoder 25. Second
Row electrode selection signal Sc so as to select the row electrodes X ₂ of row is output to the drive circuit 27, a drive signal SM to the second row of the row electrodes X _2, based on the driving circuit 27 row electrode selection signal Sc Add. The drive signal SM is applied to the row electrodes X ₂ of the second row sequentially to the column electrodes Y _j from the first column to the n-th column in the same manner as the row electrode X ₁ of the first row. Pixels E _{2,1 to} E
_{2, n} are driven. Thus, the row electrode X
Is the direction in which the number of rows increases from the first row to the m-th row (row electrode X
(In the direction of increase in the direction of arrow XU). Also while the driving signal SM continuously to one row electrode X _i is applied, the column electrode Y _j until the n-th column from the first column, sequentially selected in a direction (arrow YU direction) the number of columns is increased Drive signal SM
Is applied. Thus the row electrodes X _i and column electrodes Y _j of intersection pixel E _{i, j} are sequentially driven. During this time, the drive circuit 23 of the column electrode selection drive circuit 14 applies the voltage V corresponding to the primary color signal output from the LCD drive control circuit 13.
1 to V3 are added, and the hue, saturation, and luminance at the time of driving the pixel Ei _{, j} are determined by the levels of the voltages V1 to V3. When all the pixels E _{1,1 to} E _{m, n} of the LCD 2 are driven, an image P is completed, and a moving image can be realized by continuously repeating the above processing. As a result, the subject in the forward direction (the direction indicated by the arrow F) is displayed on the LCD 2 as it is. (2) When Mirror Image PM is Displayed (Refer to Mirror Image PM shown in FIGS. 5 and 3) As shown in FIG. 5, when it is desired to use this camera-integrated display device instead of a mirror, The mirror image PM is displayed on the LCD 2. That is, as shown in FIG. 5, when the camera 8 is rotated (in the direction of arrow C) and turned to the side of the operator Ope (that is, the rearward direction, the direction of arrow B), the direction of the camera 8 is linked. The counter changeover switch 26 is connected to terminals 28 and 30 to form a down counter. On the other hand, the counter changeover switch 18 is kept as an up counter as in (1). This is because, when the camera 8 is directed to the operator Ope's own side (arrow B direction), the LCD 2 is inverted in both the vertical direction (arrow V direction) and the horizontal direction (arrow H direction). This is because the mirror image PM needs to be inverted only in the vertical direction (the direction indicated by the arrow V). Counter 24 of row electrode selection drive circuit 15
Since a down counter, the row electrodes X _m of the m-th row are selected by the row electrode selection signal Sc when the counter 24 has counted the first-time clock signal CLV, the row electrode X _m driving signal SM is applied Is done. On the other hand, in the column electrode selection drive circuit 14, since the counter 17 is an up counter,
When the clock signal CLH is counted, the driving signal SM is applied by selecting the _first column electrode Y1. This allows
Is selected and the m-th row electrode X _m and the row electrode Y ₁ of the first row are each driving signal SM is applied the intersection of the pixel E _{m, 1}
Is driven. When the counter 17 of the column electrode selection drive circuit 14 increments in the addition direction based on the next clock signal CLH, the second column electrode Y ₂ is selected, and the drive signal SM is applied. In this way, the m-th row electrode X _m ,
After the pixels Em _{, 1 to} Em _{, n} at all the intersections with the respective column electrodes _Yj from the first column to the n-th column are driven in the direction indicated by the arrow YU, the row electrode selection drive circuit 15 is driven. When the clock signal CLV is applied to the counter 24, the row electrode selection signal Sc is output through the BCD decoder 25, and the drive circuit 27 outputs the row electrode selection signal Sc.
The row electrode _Xm-1 of the -1st row is selected, and the drive signal SM is applied. [0030] The m-1 th row of the row electrode X _m-1, similar to the m-th row of the row electrodes X _m, the column electrodes Y _j toward the n-th column from the first column are sequentially selected To sequentially drive each pixel _{Em-1, j} . In this way, the row electrodes X are sequentially selected from the m-th row to the first row in the direction in which the number of rows decreases (the direction in which the row electrodes decrease, the direction indicated by the arrow XD). _While the drive signal SM is continuously applied to 1, the column electrode _Yj is in the direction in which the number of columns increases from the first column to the n-th column (arrow YU).
Direction), and the pixels E _{i, j} are sequentially driven. As a result, the image P displayed in the order described in (1) is displayed in the direction of decreasing the number of rows from the m-th row to the first row in (2), and the display order in the column direction is reversed. Is the same, and if the image P displayed in (1) is used as a reference, an image in which the image P is vertically inverted (that is, a mirror image PM) is obtained. According to this embodiment, when the camera unit 1 is directed to the operator Ope side (rearward direction), the mirror image PM can be displayed on the LCD 2 by the operation of the image display circuit 3.
This camera-integrated display device can be used as a mirror. In this embodiment, an example in which a mirror image is obtained by using the camera unit 1 is described. However, a mirror image can be obtained in the same manner when reproducing a VTR or receiving a TV. In this embodiment, only the case where the image P is not inverted and the case where the image P is inverted in the vertical direction are described, but by operating the counter changeover switches 18 and 26, As described below, the display state of the image P can be freely changed by reversing both the vertical direction and the horizontal direction. (3) When the image is inverted in the horizontal direction (row electrode (up
Count) to column electrode (down count)) In this case, the counter 24 of the row electrode selection drive circuit 15
Is connected to the terminal 19 and the terminal 21 of the counter changeover switch 18 of the column electrode selection drive circuit 14, and an L level voltage is applied to the counter 17 to form a down counter. [0036] Thus, the row electrodes X until m-th row from the first row are sequentially selected in a direction (arrow XU direction) the number of rows is increased, and one of the row electrode X _i is connected to the driving signal SM Is applied, the column electrodes Y _j are sequentially selected in the direction in which the number of columns decreases from the n-th column to the first column (the decreasing direction of the column electrodes Y, the YD direction indicated by the arrow), the row electrode X _i and column electrodes Y _j pixel E _i of the intersection of _{the, j} are sequentially driven. As a result, the images P displayed in the order described in (1) are displayed sequentially in the direction of decreasing the number of columns from the n-th column to the first column in (3). (1)
With reference to the image P obtained by the above, an image in a state where this is inverted in the horizontal direction can be obtained. (4) When the image is inverted in the horizontal direction and the vertical direction (row electrode (down count) to column electrode (down count)) In this case, both the row and column electrode selection drive circuits 15 and 14 The counter 2 is operated by operating the counter changeover switches 18 and 26.
An L level voltage is applied to 4 and 17 to form a down counter. Since both the counters 24 and 17 of the row / column electrode selection drive circuits 15 and 14 are down counters, both counters 24 and 17 output the first clock signals CLH and C
At the time of counting the LV, the row electrodes X, the row electrodes X _m and the column electrodes Y in the m-th row, the n-th column electrode Y _n is selected each driving signal SM is applied. [0040] In this way, row electrodes X until the first row from the m-th row are successively selected in the direction (arrow XD direction) the number of rows is reduced, also continues to be driven to one row electrode X _i while the signal SM is applied, the column electrode Y _j will be sequentially selected in the direction (arrow YD direction) the number of columns is decreased toward the first row from the n-th column, and the row electrode X _i The pixels E _{i, j at} the intersections of the column electrodes Y _j are sequentially driven. As a result, in (4), images are sequentially displayed in the direction in which the number of rows decreases from the m-th row to the first row, and in the direction in which the number of columns decreases from the n-th column to the first column. If the image P obtained in (1) is used as a reference, an image obtained by inverting the image P in both the vertical and horizontal directions can be obtained. The present invention is not limited to the present embodiment, but can be applied to any of a simple matrix system, an active matrix system, and a double matrix electrode driving system. However, the present invention is not limited to this type of LCD, and can be applied to any type of LCD. In this embodiment, an example has been described in which the camera unit 1 is rotatable around the horizontal support shaft 6 to obtain a mirror image PM. When the camera unit is provided in a vertical state and forms a vertical support shaft, and a camera unit is provided around the vertical support shaft, so-called a turret-shaped camera unit is formed, the image is inverted in the horizontal direction to obtain a mirror image. According to the present invention, it is possible to take an image of the subject on the operator side including the operator by rotating the camera unit. As a result of rotating the camera unit, the captured image is upside down, left and right. In this invention, since the driving direction of the liquid crystal display device is reversed in both the horizontal and vertical directions, the display can be displayed in the correct orientation in the vertical and horizontal directions, as in the case of normal shooting.
