2. Circuit Configuration FIG. 3 is a block diagram of the endoscope apparatus 1 for explaining the hardware configuration of the main body 2. The main body 2 includes a CPU 11, a ROM 12, a RAM 13, an interface unit (hereinafter abbreviated as I / F) 14 with the LCD 4, an I / F 16 with the storage medium 15, and an I / F 17 with the operation unit 5. And are connected to each other via a bus 18. The storage medium 15 is detachably attached to a slot 19 provided in the main body 2.

An operation signal from the operation unit 5 is input to the I / F 17. The main body 2 receives an operation signal from the operation unit 5.
The ROM 12 stores software programs (hereinafter simply referred to as programs) for realizing various functions of the endoscope apparatus 1, and the CPU 11 executes the programs. The CPU 11 operates to perform various functions according to the received operation signal from the operation unit 5.

When the menu display button 5d provided on the operation unit 3 is operated, a signal corresponding to the operation is input to the CPU 11 via the I / F 17 and detected. The CPU 11 executes various operation controls, display controls, and the like based on the detected signal.
For example, as will be described later, when the menu display button 5d is operated, the CPU 11 executes processing such as displaying a menu screen on the LCD 4, which is a monitor, according to the display state, setting state, and the like at that time. .
In FIG. 3, components other than the LCD screen display control described in the present embodiment, such as power supply and communication with the outside, are omitted.

  When a user who is an inspector uses the endoscope apparatus 1 to inspect, for example, a turbine blade in an aircraft engine to be inspected, the user inserts the insertion unit 7 into the engine by operating the insertion unit 7 by hand. Then, the examination is performed while viewing the endoscopic image displayed on the LCD 4.

Although the endoscope apparatus 1 has various functions, generally, a live endoscopic image (hereinafter also simply referred to as a live image) is displayed on the LCD 4, and the examiner can use the live endoscopic image. When it is desired to acquire a still image of the image, the freeze button 5k is pressed. By this button operation, the still image can be recorded in the storage medium 15.
Next, display processing of the endoscope apparatus 1 will be described. First, the title input process according to the present embodiment will be described.
3. Processing for Menu Screen Display and Title Input Screen Display Now, assume that the examiner presses the freeze button 5k while viewing a live endoscope image. FIG. 4 is a flowchart illustrating an example of a processing flow when the freeze button 5k is pressed. FIG. 5 is a diagram for explaining an example of transition of screens displayed on the LCD 4. FIG. 4 will be described with reference to FIG. The processing in FIG. 4 is performed by the CPU 11 reading and executing a program stored in the ROM 12. FIG. 4 shows a part of the process mainly relating to the display of the menu display screen in the program.

  When the freeze button 5k is pressed, the CPU 11 executes still image data generation processing for generating a still image from the video signal from the image sensor at the distal end portion 8 of the insertion portion 7 (step S1). As a result, the obtained still image is displayed on the LCD 4 as a live / freeze screen G1. The live / freeze screen G1 is a screen on which a live image is normally displayed, but a still image is displayed when the freeze button 5k is pressed. The return from the still image to the live image is performed by pressing the live image display button 5c or the menu display button 5d. Note that, depending on the setting for recording on the endoscope apparatus 1, the endoscope apparatus 1 is set to a mode in which both a still image and a moving image are recorded by pressing the freeze button. In that case, in step S1, a process of generating still image data and moving image data is performed. In this state, a still image based on the generated still image data is displayed on the LCD 4. The still image data at this time is temporarily stored in the RAM 13.

Next, it is determined whether or not the user has pressed the menu display button 5d (step S2). When the menu display button 5d is pressed, that is, when a menu screen display instruction is issued, YES is determined in the step S2, and the CPU 11 displays the screen on the LCD 4 as shown by an arrow A1 in FIG. Is changed to the menu screen G2 and displayed (step S3).
Step S2 constitutes a menu display instruction section for inputting an instruction for displaying a menu screen in a hierarchical structure on the LCD 4.

  FIG. 6 is a diagram showing the configuration of the menu screen G2. The menu screen G2 is a graphical user interface (GUI) displayed when the menu display button 5d is pressed, that is, when a menu screen display instruction is issued.

  As shown in FIG. 6, the menu screen G2 is the uppermost layer screen and includes a menu item display unit 101 including a plurality of menu items, and a lower layer screen that displays a lower layer screen corresponding to the menu item in a selectable state. A layer display unit 102. As will be described later, since the icon in the selectable state is the icon 101b1 in FIG. 6, the content corresponding to the icon 101b1 is displayed on the lower layer display unit 102. As shown in FIG. 6, the menu screen G2 is displayed in such a form that the lower layer display unit 102 covers a part of the upper layer display unit 101. At this time, the lower layer display unit 102 which is the display unit of the lower layer displays the upper layer display so that the items of the upper layer display unit 101 which is the display unit of the upper layer, that is, the items of the icons 101b1 to 101b6 can be seen. It is displayed so as to be superimposed on the part 101.

  The menu item display unit 101 includes a display area for displaying a “menu” character 101a indicating that it is the highest layer screen and a plurality of icons 101b corresponding to a plurality of selectable menu items. Here, the plurality of icons 101b are six icons arranged in the vertical direction on the screen.

  The uppermost icon 101b1 is an icon for displaying a title input screen. Similarly, the icon 101b2 below the icon is an icon for displaying a screen related to execution of white balance. Further, an icon 101b3 below the icon 101b3 is an icon for displaying a screen related to setting of the recording mode.

  Below that, an icon 101b4 for displaying a date and time adjustment screen, an icon 101b5 for displaying a setup screen, and an icon 101b6 for displaying a language setting screen are displayed.

  Three icons 101b1 to 101b3 are icons for functions that are relatively frequently used by the user, and three icons 101b4 to 101b6 are icons that are relatively less frequently used than the above three icons. Icon.

  Returning to FIG. 4, in the menu screen G2 when the menu display button 5d is pressed and displayed in step S2, the title input screen is displayed in a selectable state among the menu items. That is, as shown in FIG. 6, the icon 101b1 for the title input screen can be distinguished from the other icons 101b2 to 101b6, that is, the icon 101b1 can be identified, and the frame of the icon 101b is displayed thickly. Is displayed to indicate that it is in a selectable state. The icon selectable state refers to a state in which the function of the icon can be executed only by receiving an execution instruction. Further, a title input screen corresponding to the selectable icon 101b1 is displayed on the lower layer display unit 102 in a grayed out state. The gray-out display refers to a low-luminance display using achromatic colors such as a decrease in luminance and a change in color, for example, in which only white and black colors are displayed.

  Note that the title input screen, which is a text input screen, is displayed in a selectable state while displaying the input text if there is input text related to the image data.

In other words, immediately after the process transitions from step S2 to S3 and the menu screen G2 is displayed, the menu item display unit 101 of the menu screen G2 indicates that the title input screen is selectable, In addition to indicating to the user that the menu item can be selected, the content of the title input screen is displayed on the grayed out lower layer display unit 102 so that the user can see it.
Step S3 constitutes a text input screen display unit that displays a text input screen for inputting text data related to image data as inspection data on the screen of the LCD 4 in a selectable state.

  Here, the icons in the selectable state are made thicker in the icon frame, but may be distinguished from other icons by highlighting such as changing the color.

  In the screen state of FIG. 6, when one item is selected from the six menu items by the user, the processing shifts to processing of the selected menu item as indicated by an arrow A2 in FIG. (Step S4). The processes in steps S3 and S4 constitute a display control unit.

For example, in the screen state of FIG. 6, when the user presses the confirm button, that is, presses the joystick 5e or tilts to the right, the menu item for title input is selected, and the CPU 11 displays the lower layer display portion of the title input screen G2. 102 enables the title input. As a result, the screen of the LCD 4 is changed to the menu screen G2b1 (FIG. 8) in a title input enabled state.
Pressing the joystick 5e constitutes a confirmation instructing unit that instructs confirmation of selection of selectable items in the menu display.

  Note that the process of step S4 in FIG. 4 is executed even when a retrieve menu screen described later is displayed.

FIG. 7 is a flowchart showing the contents of the process in step S4. First, the contents of the processing in FIG. 7 will be briefly described, and the specific contents of each processing in FIG. 7 will be described later using a display example of a screen.
First, the CPU 11 highlights the display section of the hierarchy selected on the menu screen G2 (ie, the active hierarchy) (step S11).

Next, the CPU 11 displays the items in the selectable state so that they can be identified, that is, can be distinguished from other items (step S12).
Then, the CPU 11 displays the items related to the selected hierarchy in the upper hierarchy display section so that they can be identified, that is, can be distinguished from other items (step S13).

  Further, the CPU 11 displays items related to the selectable items in the lower hierarchy display section (step S14). In step S14, if there is an item that has already been selected or set in the lower hierarchy, a process of displaying the already selected or set item so that it can be identified, that is, distinguished from other items is also performed. Is called.

  That is, in step S4 constituting the display control unit, the display unit of the hierarchy selected on the instructed and displayed menu screen is emphasized compared to the display units of the upper and lower hierarchies than the selected hierarchy. When the display part of the selected hierarchy is highlighted and displayed, the items in the higher hierarchy related to the selected hierarchy are displayed in an identifiable manner and related to the item of the selected hierarchy. Among the items in the lower hierarchy, the already set items are displayed so as to be identifiable.

  Further, when displaying the selected hierarchy and its related lower hierarchy, the display section of the selected hierarchy is superimposed on the display section of the upper hierarchy so that the items of the higher hierarchy can be seen. The display unit of the lower hierarchy that is displayed is displayed so as to overlap the display unit of the selected hierarchy so that the item of the selected hierarchy can be seen.

Note that step S12 is not executed if no selectable item is set or selected. Similarly, step S13 is not executed unless there is a higher hierarchy with respect to the selected hierarchy, and step S14 is not executed unless there is a lower hierarchy with respect to the selected hierarchy.
Furthermore, the order of the four processes of steps S11 to S14 may not be the order shown in FIG.

The return from each menu screen to the menu screen G12 can be performed by pressing the menu display button 5c or tilting the joystick 5e to the left.
Furthermore, in the state of FIG. 6, the joystick 5e is tilted to the right (that is, an operation meaning moving the upper layer to the left lower layer is performed on the screen of FIG. 6). The menu screen G2b1 is changed.

  When the menu display button 5d or the live screen display button 5c is pressed in the display state of the menu screen G2 in FIG. 6, the screen returns to the live / freeze screen G1, as indicated by an arrow A3 in FIG.

  Therefore, the user can select a desired hierarchy in the hierarchy structure according to pressing of the confirm button or tilting of the joystick 5e, and can make it active. For example, on the menu screen, the user changes the state where the menu item display unit 101 of the menu screen G2 shown in FIG. 6 is active to the state where the lower layer display unit 102 is active as shown in FIG. Can do.

  Further, the return from each menu screen to the live / freeze screen G1 can be performed by selecting setting or execution of the item function in the lower layer display section or by pressing the live screen display button 5c.

  FIG. 8 is a diagram showing a menu screen G2b1 in a title input enabled state. As shown in FIG. 8, when the title input is enabled, the upper layer display unit 101 is grayed out, and the lower layer display unit 102 is highlighted and brightened. This is because the lower layer display unit 102 is displayed in a more emphasized manner than the upper layer display unit 101 by the process of step S11 in FIG. 7, the lower layer display unit 102 is related to the item indicated by the icon 101b1 of the upper layer display unit 101, so that the icon 101b1 can be distinguished from the other icons 101b2. , Displayed with a thick frame.

  The title input screen of the lower layer display unit 102 includes a "title input" character 102a indicating that the lower layer is for title input, a title input field 102b indicated by a dotted line, a serial number setting unit 102c, a software A wear keyboard display section 102d, a preset button 102e, an entry button 102f, a cancel button 102g, and a creation button 102h are included.

  When the screen changes from FIG. 6 to FIG. 8, the cursor 102i indicating the character input position is displayed so as to be positioned at the head position (the leftmost position in FIG. 8) of the title input field 102b. If there is already input text data, the cursor 102i is displayed at a position (right side) next to the last character of the input text.

  In the state of the menu screen G2b1 in FIG. 8, the user can input characters into the title input field 102b using the software keyboard 102d.

In addition, it can also be set as the screen which can input Kana by switching the symbol which is not shown in figure and Kana input.
FIG. 9 is a diagram illustrating an example of character input. The user operates the joystick 5e of the operation unit 3 to move the cursor (not shown) on the screen and sequentially select the characters to be input, thereby selecting the characters selected in the title input field 102b. A title consisting of can be entered. FIG. 9 shows a state where the character “E” is selected and the character “E” is input to the title input field 102b. In FIG. 9, the fact that the character “E” has been selected is indicated by the fact that the frame of the character “E” is displayed thick, and that the character “E” has been input to the character input field 102b. Is also shown.

The number set in the serial number setting unit 102c is added to the input title. The serial number setting unit 102c is a portion where a plurality of digits, in this case, a three-digit number is displayed, and can be incremented or decremented by the user performing a predetermined operation.
Note that the title characters may be input by a title input method other than the method described with reference to FIGS.

  Further, even if the user inputs the title to be added to the still image obtained by freezing by the input method shown in FIG. 8 or the like, if the cancel button 102g is selected, the process is not performed, and the live / freeze screen is displayed. Return to G1 display. To do nothing is to discard the edited content of the input title. When the creation button 102h is selected, the CPU 11 associates the input text data with the still image data. Thereafter, the processing returns to the display of the live / freeze screen G1.

  When the desired title is added to the still image (or still image and moving image) obtained by pressing the freeze button 5k, the screen returns to the live screen of the live / freeze screen G1. Therefore, the user can continue the examination by the endoscope apparatus 1.

  Further, after the still image is obtained by pressing the freeze button 5k again, more specifically, the menu display button 5d is pressed and the joystick 5e is subsequently pressed only by performing the operation as described above. The title can be input to the obtained still image data. When the input of the desired title is completed, the live screen is displayed again, and the state where the inspection can be continued is returned.

  Therefore, every time a user obtains a still image, the user can move to the title input screen by a simple operation, specifically, by simply pressing the menu display button 5d and the joystick 5e that is a confirmation button. Inspection can be performed efficiently.

The reason why the operation of pressing the joystick 5e as the confirmation button is necessary is that the user confirms the operation content and that menu items that are relatively frequently used are in menu items other than the title input. .
4). Retrieve screen The inspector can record the still image to be inspected on the storage medium 15 using the endoscope device 1, but the user can also display the recorded still image on the LCD 4. it can. However, the examiner sometimes wants to combine the recorded still images and the like into one folder in the endoscope apparatus 1. Further, for example, the examiner may want to copy or delete already recorded still image or moving image data.

  For this purpose, in the endoscope apparatus 1, by pressing the view button 5 f of the operation unit 5, here, by pressing and holding the view button 5 f, the live / freeze screen is displayed as indicated by an arrow A 4 in FIG. 5. The retrieve screen G11 can be displayed from the live screen of G1.

  FIG. 10 is a diagram illustrating an example of a retrieve screen. As shown in FIG. 10, the retrieve screen G11 is a screen that displays a recorded image such as a still image recorded in the storage medium 6 in a thumbnail format. In FIG. 10, nine thumbnail images are displayed in a matrix.

  Each thumbnail image displayed on the retrieve screen G11 in FIG. 10 is displayed with a “Re” mark display portion indicating the selected state. The user can mark or remove “re” for each thumbnail image. The “L” mark indicates whether or not a recording image is designated as a processing target. When the retrieval screen G11 is displayed for the first time after recording a still image or the like, the “re” mark display portion of all thumbnail images is not marked with a “re” mark. A thumbnail image can be selected as a processing target by marking a “re” mark on the “re” mark display portion.

As shown in FIG. 10, when a folder name is assigned, the assigned folder name is displayed on the upper side of the retrieve screen G11.
Further, on the screen of FIG. 10, a desired thumbnail image can be selected by a cursor not shown. The file name of the selected thumbnail image is displayed under the folder name on the retrieve screen G11, and the shooting date and title of the image corresponding to the thumbnail image are displayed at the bottom of the retrieve screen.
For example, as shown in FIG. 10, when the user attaches a “re” mark to nine thumbnail images and then presses the menu display button 5d, the screen of FIG. 11 is displayed.

  FIG. 11 is a diagram showing a configuration of a retrieve screen menu screen (hereinafter referred to as a retrieve menu screen) G12. The retrieve menu screen G12 is a graphical user interface (GUI) displayed when the menu display button 5d is pressed in the display state of the retrieve screen G11 as indicated by an arrow A5 in FIG.

  The retrieve menu screen G12 includes a menu item display unit 111 in a retrieve screen that is a top layer screen and includes a plurality of menu items, and a lower layer display unit 112 that displays thumbnail images such as recorded still images. Including. As shown in FIG. 11, the retrieve menu screen G12 is displayed in such a form that the lower layer display unit 112 covers a part of the menu item display unit 111 which is the upper layer display unit. At this time, the lower layer display unit 112, which is the display unit of the lower hierarchy, displays the upper layer display so that the items of the upper layer display unit 111, which is the display unit of the upper hierarchy, that is, the items of the icons 111b1 to 111b6 can be seen.
