Description

  The present invention relates to a technique for improving the operability of a touch panel in a display device in which a touch position detection unit, for example, a touch panel is mounted on an image display surface and the orientation of the image display surface is changed.

  Some display devices, for example, external display monitors mounted on video cameras and still cameras, are used with their orientation changed with respect to the camera body.

  This is because when the external display monitor is used at the time of shooting in place of an electroviewfinder (hereinafter referred to as EVF) (normal shooting mode), the video camera is used as a recording / playback device to play back what has already been shot and recorded. This is because it can be used in various situations, such as when viewing (VTR mode), when the operator himself becomes a subject and stands at the front of the camera and shoots while viewing an external display monitor (mirror mode).

  In addition, there is a switch on which a so-called touch panel is mounted, which is transparent on the image surface of the display device and through which an image displayed below can be seen. Such a touch panel can output a predetermined signal by directly touching an operation display image displayed as a two-dimensional image on the image display surface with a finger or the like. In addition, since the touch panel is a well-known thing, detailed description about the operation principle etc. is abbreviate | omitted. As an operation of such a touch panel, in the case of a video camera, for example, a command related to a tape running system, “stop”, “rewind”, “play”, “fast forward”, etc. and commands related to a shooting mode, “focus”, "Shutter speed", "Backlight correction", "White balance", etc. can be performed.

  By the way, in a display device equipped with a touch panel as described above, when the orientation of the external display monitor is changed with respect to the camera body, the position of the operation button display on the touch panel changes the orientation of the external display monitor. There is a problem that the operability is poor due to the difference between the front and rear states.

  That is, when the orientation of the display device is changed in the operation part of the touch panel, the coordinate position on the touch panel changes accordingly, and for the operator who is viewing the display device from the front, the vertical and horizontal directions of appearance change. This is because the position of the operation part of the touch panel changes before and after the change of direction.

  Specifically, for example, when the video camera with an external display monitor is set to the shooting mode and the display device in that state is viewed from the front, the lower left part is set to the VTR mode (inverted vertically and horizontally). When viewed from the front, the upper right part is located, and when the operator tries to perform the same operation as a predetermined operation part (operation switch) on the touch panel arranged in the lower left part in the photographing mode, the display device is moved up and down. Considering the fact that the left and right are reversed, there is a problem in that the operability is very poor because the operation part (operation switch) disposed in the upper right part has to be touched and operated. This is because even if the orientation of the display device is changed, the operator determines the position of the operation part (operation switch) of the touch panel on the basis of the state when the display device is viewed from the front.

  Therefore, in view of the above-described circumstances, the present invention prevents touch panel operability from deteriorating even when the orientation of the display device is changed in a display device equipped with a touch position detection unit, for example, a touch panel. Is an issue.

  In order to solve the above-described problems, the display device of the present invention is provided with a display unit provided with an image display surface, and a contact position detection that is provided on the image display surface of the display unit and detects a position touched from the outside. Means, direction detection means for detecting the orientation of the display means, and an image displayed on the image display surface of the display means is inverted or rotated in accordance with the detection result detected by the orientation detection means. And control means for changing the reference point of the contact position detecting means. Alternatively, it further comprises memory means in which a correspondence relationship between the coordinate position in the contact position detection means and a predetermined process is set, and the control means outputs when a predetermined operation part of the contact position detection means is contacted The coordinate conversion of the operation part touched by the signal and the detection signal from the direction detection means is performed, and a predetermined process corresponding to the coordinate position of the coordinate-converted operation part is performed.

  In addition, the imaging apparatus of the present invention includes an imaging unit that captures an image, an image display surface that displays an image captured by the imaging unit, a display unit that is rotatable with respect to the imaging device, and the display unit A touch panel provided on the image display surface, a rotation state detection unit that detects a rotation state of the display unit, and a rotation state of the display unit that is detected by the rotation state detection unit. Control means for changing the reference point of the contact position detecting means and displaying the image to be displayed on the image display surface of the display means reversed or rotated.

  Further, in the display method of the display device according to the present invention, the display means includes an image display surface, the position touched from the outside is detected by the contact position detection means provided on the image display surface of the display means, and the display The direction of the means is detected by the direction detection means, and an image to be displayed on the image display surface of the display means is reversed or rotated according to the detection result detected by the direction detection means, and the contact position Control means for changing the reference point of the detection means.

  Further, the imaging method in the imaging apparatus of the present invention captures an image by the imaging means, displays the image captured by the imaging means on the image display surface, and the display means is rotatable with respect to the imaging apparatus. A touch panel is provided on the image display surface of the display unit, the rotation state of the display unit is detected by the rotation state detection unit, and the rotation state of the display unit detected by the rotation state detection unit is detected. And a control means for changing the reference point of the contact position detecting means while displaying the image to be displayed on the image display surface of the display means reversed or rotated.

  Therefore, in the present invention, the orientation of the display device in that state is always detected regardless of the orientation of the display device. The operation can be performed based on the state that the user is watching, and the operability can be improved.

  The display device of the present invention includes a display unit having an image display surface, a contact position detection unit that is provided on the image display surface of the display unit and detects a position touched from the outside, and a direction of the display unit. According to the direction detection means to be detected and the detection result detected by the direction detection means, an image to be displayed on the image display surface of the display means is reversed or rotated and displayed, and the reference of the contact position detection means Control means for changing the point. Alternatively, it further comprises memory means in which a correspondence relationship between the coordinate position in the contact position detection means and a predetermined process is set, and the control means outputs when a predetermined operation part of the contact position detection means is contacted The coordinate conversion of the operation part touched by the signal and the detection signal from the direction detection means is performed, and a predetermined process corresponding to the coordinate position of the coordinate-converted operation part is performed.

A touch panel is provided on the image display surface of the display unit, the rotation state of the display unit is detected by the rotation state detection unit, and the rotation state of the display unit detected by the rotation state detection unit is detected. And a control means for changing the reference point of the contact position detecting means and displaying the image to be displayed on the image display surface of the display means reversed or rotated.

  Therefore, in the present invention, the orientation of the display device in that state is always detected regardless of the orientation of the display device. It is possible to operate based on the state that the user is looking at, and to improve the operability.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

  As shown in FIGS. 1 to 4 (excluding FIG. 2), the display device 1 has a rectangular shape that is long in the horizontal direction, and a touch panel 2 as a contact position detecting means is mounted on the screen. ing.

  The touch panel 2 has a voltage applied between the upper side and the lower side in a predetermined direction, and a voltage is applied between the right side and the left side, and an arbitrary part of the touch panel 2 (hereinafter referred to as “operation part”). .) When 3mn is touched, respective output voltages (X_A / D value, Y_A / D value) in the horizontal axis (X-axis) direction and the vertical axis (Y-axis) direction are obtained. It is possible to specify which operation part 3mn is touched (input). The subscript “mn” for the operation part code “3” is added in correspondence with the level of the output voltage of the touch panel 2, and for example, the upper left part is displayed as “44” in a state of reference orientation described later. (See FIG. 1).

  That is, when the display device 1 in the orientation shown in FIG. 1 is used as a reference (this orientation is referred to as “reference orientation”), the upper left part 344 is a reference point on the coordinates of each operation part 3mn of the touch panel 2 in this reference orientation. As Q, the maximum output voltage (X_A / D value max, Y_A / D value max) is output for both horizontal (X) direction output and vertical (Y) direction output when the reference point Q is touched. It has come to be. Note that the output voltages of the horizontal (X) direction output and the vertical (Y) direction output are the maximum value (X_A / D value max, Y_A / D value max) and the minimum value (X_A / D value min, Y_A / D). A value min) is prepared in advance as data.

  When another operation part 3mn is input (touched), the position on the touch panel 2 in the other operation part 3mn is determined by the output voltage (X_A / D value, Y_A / D value) and the above. It is specified by calculating respective differences in the X direction and the Y direction from the output voltage (X_A / D value max, Y_A / D value max) of the reference point Q.

  Specifically, when the amount of change in the A / D value for one memory is the A / D value X and the A / D value Y, respectively, in the X-axis direction and the Y-axis direction, The coordinate P (x, y) is Px (X-axis direction coordinate) = | X_A / D value−X_A / D value max | / A / D value XPy (Y-axis direction coordinate) = | Y_A / D value− Y_A / D value max | / A / D value Y The amount of change in the A / D value for one memory is the maximum value (X_A / D value max, Y_A / D value max) and the minimum value (X_A / D value min, Y_A / D value min) of the output voltage. Is divided by the number of memories.

  On the other hand, the display device 1 is provided with a memory means (table) 4 to which the relationship between the coordinate position Pxy determined based on the changed orientation and a predetermined process (operation) is assigned regardless of the orientation. Yes. The subscript “xy” for the coordinate position code “P” is added in correspondence with the absolute secondary coordinates of the display device 1 in a front view. For example, the lower left part is displayed as “11”. To do.

  Specifically, the coordinate position Pxy on the secondary coordinates in the state where the touch panel 2 is viewed from the front and the predetermined processing content are associated with the table 4, and when the lower left part P11 of the touch panel 2 viewed from the front is touched, The process “A” is performed. When the right adjacent part P21 of the lower left part P11 is touched, the process “B” is performed. When the right adjacent part P31 is further touched, the process “C” is performed. When the part P41 is touched, a process “D” is performed (see FIG. 2).

  Such a coordinate position Pxy is an absolute secondary coordinate position when the touch panel 2 is viewed from the front. Therefore, even if the orientation of the touch panel 2 is changed, the lower left portion of the touch panel 2 in that orientation is “P11”. ”, The right adjacent portion is“ P21 ”, the right adjacent portion is“ P31 ”, and the lower right portion is“ P41 ”.

  Thereby, for example, when the operation part 3mn input in the reference-oriented display device 1 is “lower left part P11”, the corresponding process (operation) “A” is performed in comparison with the table 4. Is done.

  Such a display device 1 may be used with its orientation changed, and the orientation of the display device 1 is rotated around the three-dimensional axes X, Y, and Z by the orientation detection means 5. The orientation is detected.

  Note that the upper and left sides of the four outer frame sides of the display device 1 shown in FIG. 1 are indicated by thick lines Sx and Sy, and the orientation of the display device 1 in each figure when the orientation of the display device 1 is changed is shown. It was made to become.

  When the display device 1 is rotated 180 degrees around the horizontal axis X from the reference orientation and the display device 1 is viewed from the back side of the sheet of FIG. 3 (the same as the state where the display device 1 is rotated 180 degrees around the vertical axis Y). ), And the display device 1 is oriented as shown in FIG. 4 (this orientation is referred to as “vertical up / down direction”), and the thick lines Sx and Sy are respectively positioned on the lower side and the right side in FIG. The reference point Q has been moved to the lower right part. This orientation is the same as that when rotated 180 degrees around the axis Z (paper surface orthogonal axis) Z orthogonal to the paper surface.

  In such a display device 1 that is turned upside down, left and right, the orientation detection means 5 detects that the display device 1 is turned upside down, left and right, and determines a new reference point R on the touch panel 2. To do.

  Note that the fact that the display device 1 has been turned upside down, left and right is detected by the orientation detection means 5, and based on this, it is determined that the reference point (upper left part) for determining the coordinates of the touch panel 2 is "R". Is done.

  The reference point R is a reference for specifying each operation part 3mn of the touch panel 2 by the secondary coordinate position Pxy, and even if the orientation of the display device 1 is changed as described later, the operator Is set to the upper left part when the display device 1 is viewed from the front. Thereby, when the display device 1 is turned upside down, left and right, the output voltage output when the new reference point R is touched is the minimum value for both the horizontal (X) direction output and the vertical (Y) direction output. (X_A / D value min, Y_A / D value min) is output.

  The coordinates P (x, y) of the operation part 3mn input on the touch panel 2 of the display device 1 in the up / down / left / right reversed direction is Px (coordinates in the X-axis direction) = | X_A / D value−X_A / D value min | / A / D value XPy (coordinate in the Y-axis direction) = | Y_A / D value−Y_A / D value min | / A / D value Y

  Thereby, even when the display device 1 is turned upside down, left and right, the coordinate position Pxy of the arbitrary operation part 3mn on the touch panel 2 can be obtained based on the new reference point R. For example, when the operation part 3mn input in the display device 1 in the up / down / left / right reversal orientation is “lower left part P11”, a corresponding process (operation) is performed in comparison with the table 4, The same processing (operation) as when “lower left part P11” is input in the display device 1 in the reference direction is performed.

  Therefore, the operator views the display device 1 in the reference direction in front, for example, when inputting “lower left part P11”, and when viewing the display device 1 changed in the up / down / left / right reversal direction, The same processing (operation) “A” as that for inputting “lower left part P11” can be performed.

  5 to 15 show the display device 1 applied to an external display monitor 7 of a video camera 6.

  The video camera 6 includes an EVF 8 and an external display monitor 7 as an image display system for displaying an image of a subject or a reproduced image at the time of shooting or reproduction (see FIGS. 5 and 7 to 10).

  The EVF 8 and the external display monitor 7 are different in size, but both use a liquid crystal display (LCD) or the like as a display device.

  Further, the external display monitor 7 is supported with respect to the video camera body 6a so as to be openable and closable and rotatable (180 ° can be turned upside down) as shown by arrows in FIG. The external display monitor 7 has an LCD panel 9 and a touch panel 11 attached to the image display surface 10 of the LCD panel 9, and the touch panel 11 is configured to be transparent so that an image displayed on the image display surface 10 can be seen. ing.

  In addition, the video camera 6 includes a video signal processing unit 13 that converts an image projected by the optical system 12 into an electric signal, an LCD controller 14 for displaying an image on the LCD panel 9, and various operations described later on the touch panel 11. .., An OSD (On Screen Display) controller 16 for creating display images 15, 15,..., A microcomputer 17 that controls these controllers 14, 16, and a monitor orientation that detects the orientation of the external display monitor 7 And a detection switch 18 (see FIG. 5).

  The OSD controller 16 creates operation display images 15, 15,... On the touch panel 11 and outputs them to the LSD controller 14 as electrical signals. Here, “◯” 15a, “▽” 15b, “Δ” 15c, and “□” 15d are displayed as various operation display images 15, 15,... (See FIG. 5). In addition, for example, an operation command for the video camera 6 may be displayed.

  The LSD controller 14 mixes the video signal output from the video signal processing means 13 and the operation display signals of the operation display images 15, 15,... Output from the OSD controller 16, and outputs them to the external display monitor 7. To display a screen (see FIG. 5).

  The monitor orientation detection switch 18 is built in a hinge portion between the video camera body 6a and the external display monitor 7, and detects the orientation of the external display monitor 7 with respect to the video camera body 6a. This is output to the microcomputer 17. Specifically, the open / closed state of the external display monitor 7 with respect to the video camera body 6a and the rotating state with the horizontal axis as the rotation axis are detected. The state is “VTR mode”, and the 180 ° rotated state in the open state is “mirror mode”. Here, “normal shooting mode” means that the external display monitor 7 is used mainly for shooting instead of the EVF 8 (see FIG. 8), and “VTR mode” means that the video camera 6 is a recording / playback device. When the camera is used mainly as an image and recorded and played back (see FIG. 9), the “mirror mode” means that the operator himself becomes a subject and stands at the front of the camera while looking at the external display monitor 7. (See FIG. 10). Each mode is determined by the microcomputer 17 based on the detection output of the monitor direction detection switch 18 described above depending on the direction of the external display monitor 7 relative to the video camera body 6a (see FIG. 5). The monitor orientation detection switch 18 will be described later.

  When detecting the orientation of the external display monitor 7 with respect to the video camera body 6a, the microcomputer 17 outputs a command to the LCD controller 14 to invert or rotate the display screen. In response to this, the LCD controller 14 displays an image to be displayed on the LCD panel 9 by inverting or rotating the video signal and the operation display signal (see FIG. 5).

  The monitor orientation detection switch 18 includes, for example, a first switch 20 that detects opening / closing of the external display monitor 7 with respect to the video camera body 6a, and a second switch 21 that detects rotation of 180 degrees with respect to the horizontal axis of the external display monitor 7. Consists of.

  Specifically, as shown in FIG. 7, when the external display monitor 7 is closed with respect to the video camera body 6a, the first switch 20 is turned off, and the external display monitor is shown in FIG. When 7 is opened with respect to the video camera main body 6a, it becomes "ON".

  Further, in the state of FIG. 8, the second switch 21 is “OFF”. From this state, the external display monitor 7 rotates 180 degrees around the horizontal axis X (inverted), the state of FIG. When this happens, the second switch 21 is turned "ON".

  As a result, as shown in FIG. 15, it is detected that the normal shooting mode is in the state where the first switch 20 is “ON” and the second switch 21 is “OFF”, and the first switch 20 is turned “ON”. , It is detected that the second switch is in the “ON” state and in the mirror mode, and further, the first switch is “OFF” and the second switch 21 is in the “ON” state and the VTR mode is set. Is detected. Note that the mode is not limited to the monitor orientation detection switch 18 as described above, and the movement of the external display monitor 7 may be detected by an acceleration sensor or the like.

  FIG. 6 is a flowchart showing a flow for converting an operation part of the touch panel 11 into a coordinate position on the touch panel 11 and performing a predetermined process corresponding to the coordinate position in each mode.

  That is, in step 1, it is detected whether or not there is an input on the touch panel 11. When there is no input, the predetermined operation (processing) is not performed, and when there is an input, the process proceeds to Step 2.

  In step 2, it is determined whether or not “normal shooting mode?”. If it is the normal shooting mode, the process proceeds to step 3.

  If it is determined in step 2 that “the camera is not in the normal shooting mode”, the process proceeds to step 4 to determine “is it the VTR mode?”. As a result, if it is determined that the mode is “VTR mode”, the process proceeds to step 5. If it is determined that the mode is not “VTR mode”, the process proceeds to step 6.

  Note that the determinations in step 2 and step 4 are made as described above by the monitor orientation detection switch 18, for example.

  The normal shooting mode determined in step 2 is to shoot the external display monitor 7 instead of the EVF 8 of the video camera 6, and the external display monitor 7 with respect to the video camera body 6a is changed from the state of FIG. 7 to FIG. It opens in the state as shown (rotated 90 degrees around the vertical axis Y), and the image is taken while viewing the image of the subject displayed on the external display monitor 7. A state in which the external display monitor 7 is viewed from the front in the normal photographing mode as a “reference orientation” will be described below (see FIG. 8).

  On the external display monitor 7 in the normal photographing mode, a mixed image obtained by mixing the video signal output from the video signal processing means 13 and the display signal for operation created by the OSD controller 16 is taken and created. Displayed in the specified orientation. The operation display images 15, 15,... Are displayed in the order of “◯” 15 a, “▽” 15 b, “△” 15 c, “□” 15 d from the left side in FIG. When each operation part 19mn (1941, 1931, 1921, 1911) on the touch panel 11 corresponding to the operation display images 15a, 15b, 15c, 15d is touched separately, each operation display image 15a, 15b, 15c, 15d is touched. Corresponding content operations are performed. The subscript “mn” for the operation part code “19” is added corresponding to the level of the output voltage of the touch panel 11. For example, the upper left part is “44” when the external display monitor 7 is in the reference direction. Is displayed (see FIG. 11).

  That is, when an operation part 19mn on the touch panel 11 corresponding to a predetermined operation display image 15 is touched (input), the operation part 19mn on the touch panel 11 touched (input) on the secondary coordinates on the touch panel 11 is displayed. The position Pxy is detected in the same manner as that described in the above-described embodiment, and the touch is performed in accordance with the table 4 assigned so that the coordinate position Pxy corresponds to a predetermined process (operation) corresponding thereto. Processing (operation) corresponding to the operated part 19mn is executed. The subscript “xy” for the coordinate position code “P” is added in correspondence with the absolute secondary coordinates of the display device when viewed from the front. For example, the lower left part is displayed as “11”. .

  Specifically, the table 4 corresponds to the coordinate positions P11, P12, P13, and P14 on the secondary coordinates when the touch panel 11 is viewed from the front, and predetermined processing contents (A, B, C, and D). When touching the lower left part P11 of the touch panel 11 when viewed from the front, the "A" process (operation) is performed, and when touching the right part P12 of the lower left part P11, the "B" process (operation) is performed. Touching the right adjacent part P13 performs "C" processing (operation), and touching the lower right part P14 performs "D" processing (operation).

  Therefore, for example, the operation part 1941 of the touch panel 11 corresponds to the part where “◯” 15a is displayed. When the operation part 1941 is touched, an absolute secondary coordinate position P11 is obtained. The “A” operation is executed.

  Since the secondary coordinate positions P11, P12, P13, and P14 are associated with the operation display images 15a, 15b, 15c, and 15d, respectively, the operator can display the operation display images 15, 15,. Based on the above, processing (operation) corresponding to these can be easily grasped visually.

  The VTR mode determined in step 4 is for replaying and viewing what has already been shot and recorded using the video camera as a recording / reproducing device. In this case, the external display monitor 7 is displayed on the video camera main body 6a. The external display monitor 7 is turned 180 degrees around the horizontal axis X from the normal shooting mode and is further closed with respect to the video camera body 6a. The external display monitor 7 is in an inverted state (see FIG. 9).

  Since the image displayed on the external display monitor 7 in such a state is the same as the normal shooting mode when viewed from the front, the video image and the operation display image need to be reversed vertically and horizontally.

  Therefore, the monitor orientation detection switch 18 detects the state in which the external display monitor 7 is inverted vertically and horizontally, and outputs this to the microcomputer 17. The microcomputer 17 inverts the above mixed image signal vertically and horizontally to the LCD controller 14. Thus, the same image as that displayed in the normal photographing mode is displayed on the external display monitor 7 even when the external display monitor 7 whose orientation has been changed is viewed from the front. FIG. 12 shows an image in a state in which a video image and an operation display image are inverted up and down and left and right.

  In other words, the external display monitor 7 that is inverted vertically and horizontally is also displayed in the order of “◯” 15a, “○” 15b, “Δ” 15c, and “□” 15d from the left side (see FIG. 12).

  However, in such a VTR mode, the touch panel 11 is also turned upside down and left and right. Therefore, the operation part 19mn is turned upside down and left and right, and the operation on the touch panel 11 in the reference direction is performed. In parts 1941, 1931, 1921, and 1911, the operation part 1941 is the upper right part, the operation part 1931 is the left side, the operation part 1921 is the left side, and the operation part 1911 is the upper left part. (See FIG. 12).

  Therefore, the operation part 1914 corresponds to the “◯” 15a (see FIG. 12).

  Therefore, as described in the above embodiment, the coordinate position Pxy for the operation part 19mn is replaced with the reference point, and based on this, the coordinate position Pxy of each operation part 19mn is calculated, and the coordinate positions P11, P12, P13, Those corresponding to P14 are required to be operation parts 1914, 1924, 1934, 1944.

  Specifically, for example, when the operation part 1914 of the touch panel 11 corresponding to “◯” 15a is touched, the coordinate position P11 is calculated based on the output signal, and the “A” operation is executed based on the table 4. It has become.

  As described above, even in such a VTR mode, the secondary coordinate positions P11, P12, P13, and P14 correspond to the operation display images 15a, 15b, 15c, and 15d, respectively. Based on the images 15, 15,..., It is possible to easily grasp the processing (operation) corresponding to them visually.

  If the VTR mode is not determined in step 4, the mirror mode is determined, and the mirror mode is for the operator himself to take a picture while standing in front of the video camera 6 and looking at the external display monitor 7. In this case, the external display monitor 7 is turned 180 degrees around the horizontal axis X from the normal shooting mode, and the external display monitor 7 is upside down, left and right (see FIG. 10). reference).

  In the mirror mode, since the video image is displayed as if looking at the mirror, the external display monitor 7 has already been turned upside down. It is necessary to display the reversed version.

  Therefore, the microcomputer 17 outputs a command to the LCD controller 14 to invert the mixed display image only up and down based on the output signal that is detected as the mirror mode of the direction detection switch 18.

  However, the LCD controller 14 controls the mixed display image obtained by mixing the video signal and the operation display signal. Therefore, when only the upper and lower sides of the mixed display image are inverted and displayed, the operation display images 15a and 15b are displayed. , 15c and 15d are also reversed right and left, and “O” 15a displayed in the lower left of the operation display images 15, 15,... In the reference orientation is displayed in the lower right.

  In such a state, if the operator touches this to perform “A” processing (operation) based on the display of “◯” 15a displayed on the lower right, the position where the “○” 15a is displayed is For the touch panel 11, it is the operation part 1944, and the input of this position is the coordinate position P 14 of the touch panel 11, and according to the above table 4, the processing (operation) is “D” processing (operation). Become.

  Therefore, the reference point is reset to (X_A / D value max, Y_A / D value min), and the input coordinates P (x, y) of the operation site 19mn are set to Px (X-axis direction coordinates) = | X_A / D value−X_A / D value max | / A / D value XPy (coordinate in the Y-axis direction) = | Y_A / D value−Y_A / D value min | / A / D value Y

  Thus, when “◯” 15a displayed at the lower right of the screen is input, the operation part 1914 is input, and “A” processing (operation) corresponding to the displayed part is executed. (See FIG. 13).

  Even if the orientation of the external display monitor 7 is the same as that in the mirror mode, when the playback button of the video camera body 6a is operated, the image on the external display monitor 7 looks normal, that is, the mirror. It is preferable to display an image that is not reflected in the mirror as in the mode. In this case, it can be easily realized by detecting that the playback button is operated and instructing the microcomputer 17 to output the same mixed display image as in the VTR mode.

  In addition, when another switch, for example, a function key is provided on the video camera body 6a and an operation display image such as a menu display is displayed when the switch is operated, the direction of the external display monitor 7 is set to the mirror mode. Even if the video image is the same as the above-mentioned state, it is preferable that only the video image is displayed in an ordinary state, that is, an image that is not an image reflected in the mirror as in the mirror mode. In this case as well, when the playback button is operated, it can be easily realized by instructing the microcomputer 17 to output the same mixed display image as in the VTR mode.

  In the mirror mode, the operation display images (characters and symbols) 15, 15,... Displayed on the external display monitor 7 are in a so-called mirror character state in which the left and right are reversed. For this reason, there is a concern that the operator may misunderstand or misoperate if the direction of the characters and their symbols is meaningful. Therefore, characters and symbols in a mirror character state are stored in the OSD control 16 in advance, and when the monitor direction detection switch 18 detects that the mirror mode is detected, the microcomputer 17 determines whether the mirror 17 is in the LCD controller based on the detection signal. It is preferable to output a command so that the mixed display image is inverted only up and down with respect to 14, and to instruct the OSD controller 16 to output characters and symbols in a mirror character state.

  Further, the operation display images (characters and symbols) 15, 15,... Displayed in the mirror mode are also reversed in the order of arrangement of the characters and symbols. For this reason, there is a concern that an operator's misunderstanding or misoperation may be caused if the characters and the symbols are meaningful in the order of arrangement. Therefore, by storing characters and symbols in the mirror character state in the OSD control 16 in advance and displaying them in the reverse order, they can be easily displayed in the correct order. That is, the microcomputer 17 outputs a command to the LCD controller 14 so as to invert the mixed display image only up and down, and also outputs characters and symbols in the mirror character state to the OSD controller 16 to reverse the output order. To be As a result, only the video image is reversed left and right on the external display monitor 7, and the operation display images 15, 15,... Are in the normal and horizontal order (the lower left of the screen is “◯”, the right The bottom can be displayed in the same manner as the normal shooting mode (see FIG. 14).

  In this case, if the reference point is set in the same manner as in the VTR mode, when the “o” 15a at the lower left of the screen is input, the operation site 1914 is input and corresponds to the displayed one. The “A” process (operation) can be executed (see FIG. 14).

  In the above embodiment, the screen display (video image and operation display image 15) and contact position detection means when each mode (normal shooting mode, VTR mode, mirror mode) is set by the monitor direction detection switch 18 are used. Although the relationship with the (touch panel 11) has been described, each mode may be set by providing another mode changeover switch on the video camera body 6a. For example, if the external display monitor 7 is in the same orientation as the VTR mode (see FIG. 9) and the mirror mode can be indicated by the mode switch on the video camera body 6a side, the monitor orientation detection switch 18 Regardless of the detection result, the same video image and operation display images 15, 15,... As in the above-described mirror mode are displayed, and predetermined processing corresponding to the operation display images 15, 15,. Operation).

  In the above description, the present invention is applied to a video camera. However, for example, the present invention can also be applied to an electronic still camera having an EVF and an external monitor.

  In the above description, the mode in which the display device is rotated 180 degrees around the axis Z orthogonal to the screen has been described, but the present invention is not limited to this, That is, the present invention can be applied to a case where a horizontally long display device is set to be vertically long. For example, the present invention can also be applied to a case where a flat image display device is used with its orientation changed.
