  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 (a) shows a schematic block diagram of a digital video camera 100 incorporating one embodiment of a display control apparatus according to the present invention, and FIG. 1 (b) shows an external perspective view thereof.

  The configuration of the video camera 100 shown in FIG. 1A will be described. The CPU 101, the memory 102, the non-volatile memory 103, the image processing unit 104, the imaging unit 105, the operation unit 106, the recording medium I / F 107, the external I / F 109, and the communication I / F 110 are connected to the internal bus 150. Further connected to the internal bus 150 are a direct-view display 112 disposed on the side of the video camera 100 and an eyepiece display 113 disposed in the gaze-type finder (in the eyepiece finder). The devices connected to the internal bus 150 can exchange data with one another via the internal bus 150.

  The memory 102 is made of, for example, a RAM (a volatile memory using a semiconductor element or the like). The CPU 101 controls each unit of the digital video camera 100 using the memory 102 as a work memory in accordance with, for example, a program stored in the non-volatile memory 103. The non-volatile memory 103 stores image data, audio data, other data, various programs for the CPU 101 to operate, and the like. The non-volatile memory 103 is configured of, for example, a hard disk (HDD) or a rewritable or non-rewritable ROM.

  The imaging unit 105 includes a focusing lens, a lens group such as a zoom lens, a shutter, an aperture, an imaging device such as a CCD sensor or a CMOS sensor, and an AD converter that converts data photoelectrically converted by the imaging device into digital signals. Be done. The imaging unit 105 captures a moving image or a still image under the control of the CPU 101. Image data captured and generated by the imaging unit 105 is sent to the image processing unit 104 via the internal bus 150.

  The image processing unit 104 controls image data stored in the non-volatile memory 103 and the recording medium 108, a video signal acquired via the external I / F 109, and an image acquired via the communication I / F 110 based on control of the CPU 101. Perform various image processing on data etc. The image processing unit 104 also performs various types of image processing on the image data captured by the imaging unit 105. The image processing performed by the image processing unit 104 includes A / D conversion processing, D / A conversion processing, image data encoding processing, compression / decompression processing, enlargement / reduction processing (resize), noise reduction processing, color conversion processing, and the like. Including. The image processing unit 104 may be configured by a dedicated circuit block for performing specific image processing. Although the image processing unit 104 is described separately from the CPU 101 in order to facilitate understanding, some or all of the functions of the image processing unit 104 may be realized by a program operating on the CPU 101.

  The image processing unit 104 processes the image data captured by the imaging unit 105 in real time, and sequentially transfers the image data to both the direct-view display 112 and the eyepiece display 113 or to the selected one. Thereby, the eyepiece display 113 functions as an electronic view finder, and the direct view display 112 is used for through image display (live view display).

  When recording a captured image on the recording medium 108, the image processing unit 104 applies various kinds of image processing and compression encoding processing to the image data from the imaging unit 105 to generate an image file. The generated image file is recorded on the recording medium 108 via the recording medium I / F 107.

  The operation unit 106 is an input device configured to receive a user operation, which includes a button, a dial, a joystick, a touch sensor, a touch pad, and the like. Specifically, as shown in FIG. 1B, the operation unit 106 includes a cross key (cross direction key) 106a, an enter key 106b, and a touch panel 106c. The cross key 106 a is a direction operation unit that includes four operation members: an up button, a down button, a left button, and a right button. The cross key 106a may be configured by a single operation member capable of pressing the upper, lower, left, and right portions. The determination key 106 b is a push button and is mainly used to determine a selection item. For example, the user operates the cross key 106 a on any of the plurality of option items displayed on the direct-view display 112 and / or the eyepiece display 113 to move the cursor, thereby selecting a desired option item. By pressing the enter key 106b in this selected state, the user can confirm the selection and can instruct the CPU 101 to select the option item at which the cursor is positioned.

  The touch panel 106 c is a touch position device that is configured in a flat manner so as to be superimposed on the direct view display 112 and that outputs coordinate information according to the contact position of a finger or a stylus pen. The touch panel 106c includes various types such as a resistive film type, a capacitance type, a surface acoustic wave type, an infrared type, an electromagnetic induction type, an image recognition type and an optical sensor type, and any of them is used in this embodiment. It is also possible to use the method of

  A storage medium I / F 107 is a means for connecting a storage medium 108 such as a memory card, a CD (trademark) or a DVD (trademark), and reads and writes data on the storage medium 108 based on the control of the CPU 101.

  The external I / F 109 is an interface that can connect external devices via a wired cable or wireless and can input and output video signals and audio signals. The communication I / F 110 is means for transmitting and receiving files and control signals with an external device via the Internet 111.

  The direct-view display 112 is configured of a liquid crystal panel or the like, and is rotatably attached to the side surface of the video camera 100 in two axes via a biaxial hinge mechanism. As shown in FIG. 2B, the direct-view display 112 can be positioned in an open state in the direction opposite to the liquid subject (the direction in which the photographer is positioned). The direct-view display 112 can be stored so that the display surface faces the side surface of the video camera 100 from this position, and can be rotated in a vertical plane from the position shown in FIG. You can also. The direct view display 112 is further removable from the main body (housing) of the video camera 100 at its root portion.

  An open / close detection switch (not shown) for detecting the opening / closing of the direct view display 112 is incorporated in the two-axis hinge mechanism of the direct view display 112. When the open / close detection switch indicates the closed position of the direct view display 112 (the position where the display screen is stored facing the side of the video camera 100), the CPU 101 turns off the direct view display 112 to invalidate the display. On the other hand, when the open / close detection switch indicates the open position of the direct view display 112 (the position where the direct view display 112 is opened as shown in FIG. 1B), the CPU 101 validates the display of the direct view display 112.

  Also, the direct view display 112 is removable from the two axis hinge mechanism. A switch for detecting attachment / removal of the direct view display 112 to the biaxial hinge mechanism is provided in the biaxial hinge mechanism, and the CPU 101 controls image output to the direct view display 112 according to the state of the switch. When the direct view display 112 is removed, the CPU 101 turns off the image output to the direct view display 112.

  The eyepiece display 113 is provided in a finder 114 (FIG. 1B) disposed on the top surface of the digital video camera 100. The user can visually recognize the display image on the eyepiece display 113 through the eyepiece portion of the finder 114. The finder 114 is mechanically movable between the pullout position and the storage position, and a detection switch (not shown) detects the position of the finder 114. The CPU 101 enables or disables the display of the eyepiece display 113 based on the output of the detection switch. That is, the CPU 101 turns on (enables) the display of the eyepiece display 113 when in the pullout position, and turns off (disables) the display of the eyepiece display 113 when in the storage position.

  Since the eyepiece display 113 is to be viewed with an eye, visibility is less likely to be affected by the intensity of external light. For example, in a bright environment where strong sunlight illuminates, an image displayed on the direct-view display 112 may be difficult to view, but an image displayed on the eyepiece display 113 has visibility because external light is blocked. It can be seen well. In addition, in a dark place such as a concert hall, when display on the direct view display 112 is performed, backlight light is noticeable, but in the case of display on the eyepiece display 113, it is inconspicuous. The user can select which of the direct-view display 112 and the eyepiece display 113 to view the image according to the purpose and environment of viewing the image.

  The direct-view display 112 and the eyepiece display 113 display an image and a GUI screen that configures a graphical user interface (GUI) on the basis of the control of the CPU 101. The CPU 101 controls each unit of the video camera 100 to generate a video signal to be displayed on the direct view display 112 and / or the eyepiece display 113 according to a program. The generated video signal is supplied to the direct-view display 112 and / or the eyepiece display 113, and the direct-view display 112 and / or the eyepiece display 113 displays an image based on the supplied video signal.

  The video camera 100 has a grip portion 115 on the side of the housing, and the user can hold the video camera 100 with one hand by gripping the grip portion 115.

  The CPU 101 can detect the following operation or state on the touch panel 106c. Touching the touch panel 106 c with a finger or a pen is hereinafter referred to as touch-down. The state in which the touch panel 106 c is touched with a finger or a pen is hereinafter referred to as touch-on. Moving the touch panel 106 c while touching it with a finger or a pen is hereinafter referred to as touch-move. The release of the finger or the pen touching the touch panel 106 c is hereinafter referred to as touch-up. The state where nothing is touched on the touch panel 106 c is hereinafter referred to as touch-off.

  These operations / states with respect to the touch panel 106 c and position coordinates where a finger or a pen is touching on the touch panel 106 c are notified to the CPU 101 through the internal bus. The CPU 101 determines an operation on the touch panel 106 c based on the information notified from the touch panel 106 c. That is, the CPU 101 functions as a touch detection unit that detects a touch operation on the touch panel 106c.

  With regard to the touch move, the CPU 101 can determine the vertical component and the horizontal component on the touch panel 106c based on the change in the position coordinates also in the movement direction of the finger or pen moving on the touch panel 106c. The CPU 101 determines that a stroke has been drawn when the touch panel 106 c is touched up from the touch down through a certain touch move. The operation of drawing a stroke quickly is called a flick. The flick is an operation of quickly moving the touch panel 106c by a certain distance while keeping the finger on the touch panel 106c and releasing it as it is, in other words, an operation of tracing the touch panel 106c quickly as if it is flicking with a finger. When it is detected that the touch move is performed at a predetermined speed or more at a predetermined distance or more, and the touch-up is detected as it is, the CPU 101 determines that the touch is flick. When it is detected that the touch move is performed at a predetermined distance or more at a speed less than the predetermined speed, the CPU 101 determines that the drag is performed.

  A display example of the direct view display 112 and the eyepiece display 113 will be described with reference to FIG. FIGS. 2A1 to 2A4 show display examples of the direct view display 112 when the direct view display 112 is on. FIGS. 2B1 to 2B5 show display examples of the eyepiece display 113 when the finder 114 is at the drawing position.

  FIG. 2A1 shows a display example in the shooting standby state or moving image shooting in the direct view display 112, and FIG. 2B1 shows a display example in the shooting standby state or moving image shooting in the eyepiece display 113. As illustrated, the display contents of the direct-view display 112 and the eyepiece display 113 are the same during shooting standby state or moving image shooting. That is, the live view image 201 captured by the imaging unit 105, and various information and icons (option items) are displayed. By operating the cross key 106a to any of the displayed icons (option items) to place the cursor (thick frame in the figure) and pressing the determination key 106b, the user can select and confirm the option items. In addition, the user can select and confirm an option item by a touch operation on the touch panel 106 c with respect to the icon (option item) displayed on the direct view display 112. Hereinafter, the selection confirmation based on the operation of the cross key 106a and the determination key 106b and the selection confirmation by the touch operation on the touch panel 106c are collectively referred to simply as the selection confirmation.

  When the user selects and confirms the menu icon 202 on the screens shown in FIGS. 2A1 and 2B1, the direct view display 112 and the eyepiece display 113 have the same menu as shown in FIGS. 2A2 and 2B. Display the screen. FIG. 2 (A2) shows a display example of the menu screen on the direct view display 112, and FIG. 2 (B2) shows a display example of the menu screen on the eyepiece display 113. As illustrated, the display contents of the direct view display 112 and the eyepiece display 113 are the same on the menu screen. The menu screen displays a plurality of option items including a wireless setting icon 211 and a "close" icon 212.

  When the user selects and confirms the wireless setting icon 211 on the menu screen shown in FIGS. 2A1 and 2B1, the direct view display 112 and the eyepiece display 113 are shown in FIGS. 2A3 and 2B3. Display the same wireless setting screen. FIG. 2 (A3) shows a display example of a wireless setting menu on the direct view display 112, and FIG. 2 (B3) shows a display example of a wireless setting menu on the eyepiece display 113. As illustrated, in the wireless setting menu, the display contents of the direct view display 112 and the eyepiece display 113 are the same. On the wireless setting menu screen, a plurality of option items including a password setting icon 221, a camera name setting icon 222, and a "return" icon 224 are displayed. A password and a camera name can be input to the password setting icon 221 and the camera name setting icon 222, respectively. Therefore, next to the password setting icon 221 and the camera name setting icon 222, an icon 223 imitating a software keyboard is displayed.

  FIG. 2 (A4) shows a display example of the software keyboard screen on the direct view display 112. FIG. 2 (B4) shows a display example of the eyepiece display 113 when the software keyboard screen is displayed on the direct view display 112. Although details will be described later, as shown in FIG. 2 (A4) and (B4), when displaying the software keyboard screen on the direct view display 112, the CPU 101 does not display anything on the eyepiece display 113. In the software keyboard screen displayed on the direct view display 112, as shown in FIG. 2 (A4), various character keys, a character input field 231, an OK button 232 which is a soft key, and a cancel button 233 which is a soft key Is displayed.

  FIG. 2 (B5) shows a display example of the character input screen on the eyepiece display 113 when the display of the direct view display 112 is off. Since the display area of the eyepiece display 113 is not large enough to simultaneously display a large number of character keys, the eyepiece display 113 adopts a character input screen for selectively inputting one character each. On the eyepiece display 113, a character input box 231, a display box of input characters, an OK button 232 which is a soft key, and a cancel button 233 which is a soft key are displayed. Unlike the software keyboard screen, it is not necessary to simultaneously display a large number of characters of the input candidate in the screen, so the characters of the character input field 231 (candidate characters and confirmed characters) have a screen ratio compared to the characters of the software keyboard screen. It is displayed large on the top. Thereby, the visibility of the user can be improved.

  The above operation will be described with reference to the flowcharts shown in FIGS. 3 and 4. FIG. 3 shows a flowchart of menu screen processing. This process is realized by the CPU 101 loading a program stored in the non-volatile memory 103 into the memory 102 and executing the program. When the user selects and confirms the menu icon 202 on the shooting standby screen shown in FIGS. 2A1 and 2B1, the CPU 101 starts the process shown in FIG.

  In S301, the CPU 101 displays menu screens illustrated in FIG. 2 (A2) and FIG. 2 (B2) on both the direct-view display 112 and the eyepiece display 113, respectively.

  In S302, the CPU 101 determines whether the wireless setting icon 211 has been selected and confirmed among the option items displayed on the menu screen. That is, the CPU 101 determines whether an operation to press the determination key 106 b with the cursor set on the wireless setting icon 211 or a touch operation on the wireless setting icon 211 displayed on the direct view display 112. In the following description, it is assumed that either the operation of pressing the determination key 106 b with the cursor placed or the operation of touching the icon displayed on the direct-view display 112 may be used as the selection confirmation operation. When the wireless setting icon 211 is selected and confirmed, the CPU 101 proceeds to S306, and otherwise proceeds to S303.

  In S303, the CPU 101 determines whether or not other option items other than the wireless setting icon 211 and the “close” icon 212 have been selected and confirmed among the displayed option items. If another option item is selected and confirmed, the CPU 101 proceeds to S304 and performs processing according to the selected and confirmed item, otherwise proceeds to S305.

  In S305, the CPU 101 determines whether the close icon 212 has been selected and confirmed. When the selection is confirmed by the “close” icon 212, the CPU 101 ends the menu screen processing and returns to the shooting standby screen. If not, the CPU 101 returns to S302 and repeats the process.

  In S306, the CPU 101 displays a wireless setting menu on both the direct view display 112 and the eyepiece display 113. Display examples of the wireless setting menu are those shown in FIG. 2 (A3) and FIG. 2 (B3).

  In S307, the CPU 101 determines whether or not the password setting icon 221 or the camera name setting icon 222 is selected and confirmed among the option items displayed in the wireless setting menu. That is, the CPU 101 determines whether or not there has been an operation of a character input instruction to instruct a menu requiring character input. If the password setting icon 221 or the camera name setting icon 222 is selected and confirmed, the CPU 101 proceeds to step S308, otherwise proceeds to step S309.

  In S308, the CPU 101 performs character input processing. Details of the character input process will be described later with reference to FIG.

  In S309, the CPU 101 determines whether or not the other option items other than the password setting icon 221, the camera name setting icon 222, and the “Return” icon 224 have been selected and confirmed among the option items displayed in the wireless setting menu. . If another option item is selected and confirmed, the CPU 101 proceeds to S310 and performs processing according to the item selected and determined, otherwise proceeds to S311.

  In S311, the CPU 101 determines whether the “return” icon 224 has been selected and confirmed. If the “return” icon 224 is selected and confirmed, the CPU 101 returns to S301 and repeats the process, otherwise proceeds to S307.

  FIG. 4 shows a detailed flowchart of the character input process (S308). The character input process shown in FIG. 4 is realized by the CPU 101 developing a program stored in the non-volatile memory 103 in the memory 102 and executing the program.

  In S401, the CPU 101 determines whether the display of the direct view display 112 is valid. If the display of the direct view display 112 is valid (including the case where the display of the eyepiece display 113 is also valid), the CPU 101 proceeds to step S402. If not (including the case where the display of the direct view display 112 is invalid and the display of the eyepiece display 113 is valid and the case where the direct view display 112 is removed and can not be used), the CPU 101 proceeds to S414.

  In S402, the CPU 101 turns off the eyepiece display 113 (disables the display). More specifically, the CPU 101 hides the display of the eyepiece display 113 and turns off the backlight of the eyepiece display 113 (turns it off). When the eyepiece display 113 is a self-luminous type display such as an organic EL (Organic Electro-Luminescence) display, the display element itself of the eyepiece display 113 is turned off instead of the backlight. At this time, the screen of the eyepiece display 113 does not display anything as shown in FIG. 2 (B4). For the user looking through the finder 114, the meaning of looking at the finder 114 is lost. The user stops looking into the finder 114 and sees the software keyboard screen displayed on the direct view display 112 and inputs characters. By turning off the eyepiece display 113 in this manner, the user is urged to look away from the finder 114 and look at the screen of the direct view display 112. Since a keyboard for character input is displayed on the direct view display 112, the user is inevitably prompted to input characters. This enables the user to input characters quickly and easily.

  The CPU 101 may display guidance such as “Please operate the keyboard with the liquid crystal screen” or “The keyboard has been displayed on the liquid crystal screen” for several seconds on the eyepiece display 113 before the light is turned off. Although the direct-view display 112 is displayed to the user as a “liquid crystal screen”, the present invention is not limited to this name, and it is sufficient for the user to indicate the direct-view display 112. By displaying the guidance on the eyepiece display 113, it is possible to prompt a character input operation on the screen of the direct view display 112.

  In S403, the CPU 101 displays a software keyboard screen as shown in FIG. 2 (A4) on the direct view display 112, and in S404, the CPU 101 invalidates the cross key 106a. The invalidation of the cross key 106 a causes the cursor not to be displayed. In addition, even if the user presses the cross key 106a, the CPU 101 ignores it and does not execute control according to the press. By disabling the cross key 106a, the user can be prompted to use the touch panel 106c. By limiting the input to the touch panel 106c, the cursor movement operation is not required, and the user can perform character input by an operation of directly pressing a desired character key. That is, it is possible to cause the user to input a desired character quickly with little effort. If the cross key 106a is kept valid, S404 may be omitted. Instead of invalidating the cross key 106a, a voice may be output for prompting the user to use the touch panel in response to some operation of the cross key 106a.

  In S405, the CPU 101 determines whether or not any character key of the software keyboard screen displayed on the direct view display 112 has been touched. If the character key is touched, the CPU 101 proceeds to step S406, otherwise proceeds to step S407. When the process of S404 is omitted, the CPU 101 proceeds to S406 when any character key is selected and confirmed.

  In S406, the CPU 101 inputs a character corresponding to the character key touched. The CPU 101 holds the input character in the memory 102 and displays it in the character input field 231. Subsequently, when a character is input, the CPU 101 arranges and displays the next character in the space of the character input field 231.

  In step S407, the CPU 101 determines whether the OK button 232 displayed on the direct view display 112 is touched. The touch of the OK button 232 corresponds to an instruction to hide the software keyboard. If the OK button 232 is touched, the CPU 101 proceeds to S408, otherwise proceeds to S409. If the process of S404 is omitted, the CPU 101 proceeds to S408 when the OK button 232 is selected and confirmed.

  In step S408, the CPU 101 determines the input character (character string held in the memory 102 and displayed in the character input field 231), sets it as a password or a camera name, and records (stores) it in the nonvolatile memory 103. .

  In S409, the CPU 101 determines whether the cancel button 233 displayed on the direct view display 112 is touched. The touch of the cancel button 233 corresponds to an instruction to hide the software keyboard. If the cancel button 233 is touched, the CPU 101 proceeds to step S410. If not, the process returns to step S405 and repeats the processing from step S405. When the process of S404 is omitted, when the cancel button 233 is selected and confirmed, the CPU 101 proceeds to S410.

  In S410, the CPU 101 discards (clears) the input character (the character string held in the memory 102 and displayed in the character input field 231).

  In S411, the CPU 101 turns on (turns on) the direct-view display 112 that has been extinguished in S401.

  In S412, the CPU 101 enables the cross key 106a that has been invalidated in S404.

  In S413, the CPU 101 displays a wireless setting menu on both the direct-view display 112 and the eyepiece display 113 as shown in FIGS. 2 (A3) and (B3). When the process of S414 is finished, the CPU 101 ends the character input process, and returns to S307 of FIG.

  In S414, the CPU 101 displays a character input screen as shown in FIG. 2 (B5) on the eyepiece display 113, and sets the cursor in the first character input field 231. In the subsequent processing, the user can input each character of the character string to be input one by one. Select the character to be input with the up and down keys, and select the input position with the left and right keys. The operation of the left / right key, the enter key or the OK button 232 in the state where any character is selected in the input column to be noticed means the confirmation of the selected character. Although the operation of the determination key does not change the character input position, the operation of the left and right keys involves processing to move the character input position to the left and right, respectively. The operation of the OK button 232 means confirmation and end of the input character string. The operation of the cancel button 233 means the cancellation of the character input operation including the halfway input.

  In S415, the CPU 101 determines whether the up / down key of the cross key 106a is operated in the character input field 231 of the character input screen displayed on the eyepiece display 113. If the up and down keys have been operated (S415), the CPU 101 proceeds to S416, otherwise proceeds to S417. In S416, the CPU 101 changes the character at the position where the cursor is located in response to the operation of the up and down keys. For example, when the character “A” is displayed, the CPU 101 displays the character “B” when the down key is pressed, and displays the character “C” when the character “A” is pressed again. Characters that can be input are held in the memory 102, and the CPU 101 cyclically displays one character from among the characters that can be input in the character input field 231 according to the operation of the up and down keys.

  In S417, the CPU 101 determines whether or not the left and right keys of the cross key 106a have been operated on the character input screen displayed on the eyepiece display 113. If the left and right keys are operated, the CPU 101 proceeds to S418, otherwise proceeds to S419. In S418, the CPU 101 moves the cursor in response to the operation of the left and right keys. Within the range of the character input box 231, the character input position can be changed by moving the cursor. The CPU 101 moves the cursor to the OK button 232 when the user performs the right operation outward from both ends of the character input field 231, and moves the cursor to the cancel button 233 when the user performs the left operation. .

  In step S419, the CPU 101 determines whether the determination key 106b is pressed while the cursor is on the OK button 232 displayed on the eyepiece display 113 (in a state where the OK button 232 is selected and confirmed). The selection confirmation of the OK button 232 corresponds to an instruction to end the character input and to hide the character input screen. If the OK button 232 is selected and confirmed, the CPU 101 proceeds to S420, otherwise proceeds to S421.

  In S420, the CPU 101 determines the input character (character string held in the memory 102 and displayed in the character input field 231), setting it as a password or a camera name, and storing it in the non-volatile memory 103. Then, the CPU 101 proceeds to step S413.

  In S421, the CPU 101 determines whether or not the determination key 106b is pressed in a state where the cancel button 233 displayed on the eyepiece display 113 is in a cursor state (a state where the cancel button 233 is selected and confirmed). The selection confirmation of the cancel button 233 corresponds to an instruction to cancel character input and to hide the software keyboard. If the cancel button 233 is selected and confirmed, the CPU 101 proceeds to S422, and otherwise returns to S415 and repeats the character input process.

  In S422, the CPU 101 discards (clears) the input character (the character string held in the memory 102 and displayed in the character input field 231), and the process proceeds to S413.

  In S413, the CPU 101 displays a wireless setting menu on the eyepiece display 113, and ends the flow of the character input process shown in FIG. A display example of the wireless setting menu is shown in FIG. 2 (B3).

  When the direct view display 112 is valid, the CPU 101 outputs a video signal of the same screen as the screen displayed on the direct view display 112 from the external I / F 107 to the outside. When the direct-view display 112 is not effective, the CPU 101 outputs a video signal of the same screen as the screen displayed on the eyepiece display 113 from the external I / F 107 to the outside. Thus, characters can be input while looking at the display screen of the display connected to the external I / F 107.

  In the above embodiment, an example is shown in which the software keyboard screen or the character input screen is displayed below the hierarchy of the wireless setting menu to input characters, but the present invention is not limited to this. Even in the other operation state, the same processing as FIG. 4 is performed in response to the operation of displaying the software keyboard screen or the character input screen. That is, even when display is performed on both the direct view display 112 and the eyepiece display 113 until immediately before, the software keyboard screen is displayed only on the direct view display 112.

  Further, as the operation for displaying the software keyboard or the character input screen, an example of the selection and determination operation of the password setting icon 221 and the selection and determination operation of the camera name setting icon 222 has been described, but it is not limited thereto. The fact that one of the character string display fields is selected and confirmed on the screen on which various character string display fields such as a password and a camera name are displayed also corresponds to an operation of displaying a software keyboard or a character input screen.

  For example, the software keyboard is not displayed, and both the password character string display field in which the password is displayed by an asterisk (*) and the camera name character string display field in which the camera name is displayed as a character string are displayed. Screen is displayed. In this screen, when the password character string display field or the camera name display field is touched or the like, and selection and confirmation is made, description will be given with reference to FIG. A character input process may be performed. In this case, when the OK button 232 is touched in FIG. 4 and the character string is stored, the character string stored in both the eyepiece display 113 and the direct view display 112 is the character string on the screen after the processing of FIG. Displayed in the display field. In the case of a password, it is displayed as asterisks, and only the number of characters is reflected.

  In the above embodiment, when displaying on the direct-view display 112 in S401, the eyepiece display 113 is turned off in S401, but guidance such as "Please operate the keyboard on the liquid crystal screen" continues to be displayed without turning off. May be Also in this case, the software keyboard screen is not displayed on the eyepiece display 113. Even if the eyepiece display 113 is not turned off, displaying such guidance on the eyepiece display 113 can prompt the user to look at the direct view display 112 and perform a character input operation. Furthermore, a character string input on the software keyboard screen displayed on the direct view display 112 may be displayed on the eyepiece display 113 without turning off the eyepiece display 113. Thereby, the eyepiece display 113 can also confirm the character input result.

  As described above, according to this embodiment, when the direct view display 112 is effective, the user can input characters with good operability using the software keyboard screen of the direct view display 112. It is possible to avoid character input while looking into the finder and improve operability. In addition, unnecessary power can be reduced as the eyepiece display 113 is not displayed at the time of character input. Therefore, it is effective for the user who has usually performed the operation by leaving the eye of the finder at the time of character input.

  The control of the CPU 101 may be performed by one piece of hardware, or a plurality of pieces of hardware may control the entire apparatus by sharing processing.
