The case where the image P and the mirror image PM are displayed will be described.       [0021]   (1) When displaying a normal image P   As shown in FIG. 4, the camera 8 is pointed at a subject (not shown), and the counter is turned off. The terminals 19 and 20 of the exchange switch 18 are connected, and an H-level voltage is applied to the counter 17. In addition, the counter 17 is set as an up counter. On the other hand, the counter changeover switch 26 The terminals 28 and 29 are connected because the camera 8 faces forward (the direction indicated by the arrow F). And the counter 24 is an up counter.       [0022]   The clock signal is supplied to the counter 24 of the row electrode selection drive circuit 15 which is an up counter. When the signal CLV is applied, the clock signal CLV is counted and the counted value is calculated. Is supplied to the BCD decoder 25 as a binary signal. The BCD decoder 25 performs the first 2 A row electrode selection signal Sc is applied to the drive circuit 27 from the value signal. The drive circuit 27 The row electrode X of the first row is determined by the pole selection signal Sc.₁Is selected and the drive signal SM is applied. .       [0023]   The clock signal is supplied to the counter 17 of the column electrode selection drive circuit 14 which is an up counter. When CLH is added, the clock signal CLH is counted and the counted value is calculated. The binary signal is supplied to the BCD decoder 22. The BCD decoder 22 performs the first binary A column electrode selection signal Sr is applied to the drive circuit 23 from the signal. The drive circuit 23 includes a column electrode The column electrode Y of the first column is selected by the selection signal Sr.₁Is selected and the drive signal SM is applied.   As a result, the first row electrode X₁And the first column electrode Y₁Drive signal S M is applied and the pixel E at the intersection is_1,1Is driven.       [0024]   The next clock signal CLH is applied to the counter 17 of the column electrode selection drive circuit 14. Then, the counter 17 is incremented in the addition direction, and the column electrode Y of the second column is increased._TwoIs a column The drive signal SM selected by the electrode selection signal Sr is applied and the pixel E_1,2Is driven . Thus, the first row electrode X₁And each column electrode Y intersecting with this_jInteraction with Point pixel E_{1, j}In the direction in which the driving of the column electrode Y increases from the first column to the n-th column (the increasing direction of the column electrode Y). (YU direction), the counter 24 of the row electrode selection drive circuit 15 When the lock signal CLV is applied, the counter 24 increments in the addition direction. After passing through the BCD decoder 25, the second row electrode X_TwoSelect row electrode to select The signal Sc is output to the drive circuit 27, and the drive circuit 27 outputs the signal Sc based on the row electrode selection signal Sc. And the second row electrode X_TwoTo the drive signal SM.       [0025]   Row electrode X of second row_TwoAlso the first row electrode X₁From the first column in the same way as Each column electrode Y up to the nth column_jAre sequentially applied to the pixel E_2,1~ E_{2, n} Is driven. In this way, the number of the row electrodes X increases from the first row to the m-th row. Are sequentially selected in the direction of application (the direction in which the row electrode X increases, the direction indicated by the arrow XU). Another Row electrode X_iWhile the drive signal SM is continuously applied to the column electrodes Y_jIs the first row The drive signals S are sequentially selected in the direction in which the number of columns increases (YU direction indicated by an arrow) from the nth to M will be applied. Thereby, the row electrode X_iAnd column electrode Y_jIntersection pixel E of_{i, j} Are sequentially driven. During this time, the drive circuit 23 of the column electrode selection drive circuit 14 Voltages V1 to V3 corresponding to the primary color signals output from the CD drive control circuit 13 are added. The level of the voltages V1 to V3 causes the pixel E_{i, j}Hue when driving, Saturation and luminance are determined. All pixels E of LCD2_1,1~ E_{m, n}Driving the picture By completing P and repeating the above processing continuously, a moving image can be realized.       [0026]   Thus, the subject in the forward direction (the direction indicated by the arrow F) is displayed on the LCD 2 as it is. Will be displayed in the state of.       [0027]   (2) When the mirror image PM is displayed (see the mirror image PM shown in FIGS. 5 and 3)   As shown in FIG. 5, when the camera-integrated display device is used as a mirror , The mirror image PM is displayed on the LCD 2. That is, as shown in FIG. Is rotated (in the direction of arrow C), the operator's own side (ie, the rearward direction, the direction of arrow B). ), The counter changeover switch 26 linked to the direction of the camera 8 is The children 28 and 30 are connected to form a down counter. On the other hand, the counter switching switch The switch 18 remains the up counter as in (1). This controls the camera 8 In the case of facing the creator Ope's own side (arrow B direction), the LCD 2 displays the image in the vertical direction (arrow direction B). (V direction) and the horizontal direction (H direction), the mirror image PM Is obtained by inverting only in the vertical direction (the direction indicated by the arrow V). Things.       [0028]   Since the counter 24 of the row electrode selection drive circuit 15 is a down counter, When the clock 24 counts the first clock signal CLV, the m-th row electrode X_mAre selected by the row electrode selection signal Sc, and the row electrode X_mDrive signal SM is applied to It is. 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 first column electrode Y₁Select the drive signal Apply SM. Thereby, the row electrode X of the m-th row_mAnd the first column electrode Y₁When Is selected, and the driving signal SM is applied to each of the pixels E at the intersection._{m, 1}Is driven.       [0029]   Then, the counter 17 of the column electrode selection drive circuit 14 changes to the next clock signal CLH. When incremented in the addition direction based on the second column electrode Y_TwoIs selected A motion signal SM is applied.       [0030]   Thus, the m-th row electrode X_mAnd each column electrode from the first column to the n-th column Y_jPixel E at all intersections with_{m, 1}~ E_{m, n}Is driven in the direction indicated by the arrow YU, When the clock signal CLV is applied to the counter 24 of the row electrode selection drive circuit 15, 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. Row electrode X of the (m-1) th row_m-1Is selected and the drive signal SM is added.       [0031]   Row electrode X of the (m-1) th row_m-1Is also the row electrode X of the m-th row._mAs in the first column Column electrode Y toward n-th column_jAre sequentially selected and each pixel E_{m-1, j}Are sequentially driven.       [0032]   In this way, the row electrodes X are arranged in the direction in which the number of rows decreases from the m-th row to the first row (row electrode X). (XD direction), and one row electrode X₁Continue to While the drive signal SM is being applied, the column electrode Y_jIs the number of columns from column 1 to column n Are sequentially selected in a direction in which the pixel E increases (YU direction indicated by an arrow), and the pixel E_{i, j}In order Drive next.       [0033]   As a result, the image P displayed in the order already described in (1) is changed to the m-th row in (2). Are displayed in the direction in which the number of rows decreases from the first row to the first row, and the display order in the column direction is the same. Therefore, if the image P displayed in (1) is used as a reference, this is An image in a rotated state (that is, a mirror image PM) is obtained.       [0034]   According to this embodiment, when the camera unit 1 is directed to the operator Ope's own side (rearward direction). In this case, the mirror image PM can be displayed on the LCD 2 by the operation of the image display circuit 3. The camera-integrated display device can be used as a mirror. Also, this implementation In the example, an example in which a mirror image is obtained using the camera unit 1 is described. A mirror image can be obtained similarly at the time of birth, at the time of TV reception, and the like.       [0035]   In this embodiment, the image P is not inverted and the image P is inverted in the vertical direction. Although only the case of turning the counter is described, the counter changeover switches 18 and 26 are operated. This allows the image to be inverted both vertically and horizontally, as described below. The display state of P can be freely changed.       [0036]   (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 not an up counter. And the terminals 19 and 21 of the counter changeover switch 18 of the column electrode selection drive circuit 14 Connected and apply an L level voltage to the counter 17 to form a down counter.       [0037]   As a result, the row electrodes X move from the first row to the m-th row in the direction in which the number of rows increases (arrow XU). Direction), and one row electrode X_iAnd the drive signal SM is applied. The column electrode Y_jIndicates a direction in which the number of columns decreases from the n-th column to the first column (column electrode (In the decreasing direction of Y and in the direction of arrow YD), the row electrodes X are selected._iAnd column electricity Pole Y_jPixel E at the intersection of_{i, j}Are sequentially driven.       [0038]   As a result, the image P displayed in the order already described in (1) becomes the n-th image in (3). Since it is displayed sequentially from the column to the first column in the direction in which the number of columns decreases, in (1) When the obtained image P is used as a reference, an image obtained by inverting the obtained image P in the horizontal direction is obtained. It is.       [0039]   (4) When the image is inverted in the horizontal and vertical directions (row electrode (down count) G)-column electrode (down count))   In this case, the counter changeover switches of the row and column electrode selection drive circuits 15 and 14 are used. By operating the counters 18 and 26 to apply the L-level voltage to the counters 24 and 17, wn counter.       [0040]   The counters 24 and 17 of both the row and column electrode selection drive circuits 15 and 14 are down-counters. Counters 24 and 17 output the first clock signals CLH and CLV. Are counted, the row electrode X becomes the row electrode X in the m-th row._mAnd the column electrode Y The n-th column electrode Y_nAre selected and the drive signal SM is applied.       [0041]   In this manner, the row electrodes X are arranged in the direction in which the number of rows decreases from the m-th row to the first row (as indicated by arrows) XD direction), and one row electrode X_iDrive signal SM is continuously applied The column electrode Y_jIndicates a direction in which the number of columns decreases from the n-th column to the first column (arrow (YD direction), the row electrodes X are sequentially selected._iAnd column electrode Y_jPainting of the intersection of Element E_{i, j}Are sequentially driven.       [0042]   As a result, in (4), the number of rows decreases from the m-th row to the first row, and Since images are sequentially displayed in the direction in which the number of columns decreases from the n-th column to the first column, ( With reference to the image P obtained in 1), this was inverted both vertically and horizontally. An image of the state is obtained.       [0043]   Note that the present invention is not limited to the present embodiment only, but rather uses a simple matrix method.
