The video processor 3 may have a configuration in which a light source device that supplies illumination light to the endoscope 2 is provided separately.

The keyboard 5 is provided on a pedestal 6 that can be pulled out. When the user uses the keyboard 5, the user can pull out the pedestal 6 from the medical trolley to input characters, and when not using the keyboard 5, the user can store the pedestal 6 in the medical trolley. In addition to the endoscope 2, the video processor 3, the display device 4, and the keyboard 5, peripheral devices such as a printer and a water feeding device may be mounted on the medical trolley.

As shown in FIG. 2, the endoscope 2 is provided at the distal end of an insertion portion to be inserted into a body cavity of a patient, and an imaging element 11 such as a CCD for imaging a subject, and a light for guiding illumination light to the distal end of the insertion portion A guide 12, an operation switch 13 provided in an operation unit for operating the endoscope 2, and an electrical connector 14 a provided in a connector unit 14 for connecting to the video processor 3 are provided.

Note that the insertion portion of the endoscope 2 may be flexible or rigid (a rigid endoscope used for surgery). Moreover, although the image pick-up element 11 is provided in the insertion part front-end | tip of the endoscope 2, it is not limited to this. For example, the image sensor 11 is provided in an operation unit (portion gripped by the user) provided with the operation switch 13, and transmits an optical image using an image guide fiber from the distal end of the insertion unit to the image sensor 11 in the operation unit. It may be a configuration.

In the present embodiment, the video processor 3 is configured to be connected to the endoscope 2, but the present invention is not limited to this, and an optical endoscope (a fiberscope or a fiberscope) inserted into a body cavity is not limited thereto. A configuration may be adopted in which a camera head to be attached to an eyepiece of a surgical optical tube) is connected.

Furthermore, in the present embodiment, the endoscope 2 and the video processor 3 are connected by the electrical connector 14a and the connector 23 and are configured to transmit electrical signals by wire, but the present invention is not limited to this. The configuration may be such that the signal is transmitted wirelessly.

The video processor 3 includes a light source 21 such as a lamp that generates illumination light, and a condenser lens 22 that condenses the illumination light from the light source 21 on the incident end face of the light guide 12.

The video processor 3 includes a connector 23 connected to the electrical connector 14 a of the endoscope 2, and a control unit 24 such as a CPU that drives and controls the imaging device 11 of the endoscope 2 via the connector 23. , A touch panel 25 for performing various operations and settings, a memory 26 for storing an endoscopic image and various information, and video processing for performing predetermined signal processing on an imaging signal from the imaging device 11 via the connector 23 And a display controller 28 that changes the character size of the character information, and a superimposing circuit 29 that superimposes the character information on the signal of the video processing unit 27. In addition, a recording medium 30 is detachably configured in the video processor 3, and an endoscopic image and various types of information can be stored in the recording medium 30.

In addition, although the light source 21 of the video processor 3 is comprised by the lamp etc., it is not limited to this, For example, you may be comprised by semiconductor light emitting elements (semiconductor light source), such as LED or a laser diode. Further, when using a semiconductor light source, a semiconductor light source that emits white light may be used. For example, a semiconductor light source is provided for each color component of R (red), G (green), and B (blue), The light of each color component emitted from these semiconductor light sources may be combined to obtain white light. Further, the semiconductor light source may be configured to be provided at the distal end of the insertion portion of the endoscope 2.

The video processing unit 27 performs predetermined video signal processing such as noise reduction processing, white balance processing, and color correction on the video signal from the image sensor 11, and outputs the obtained video signal to the superimposing circuit 29.

The display controller 28 outputs character information related to the examination displayed on the display device 4 to the superimposing circuit 29 based on the control of the control unit 24. At this time, the display controller 28 changes the size of the character information based on the control of the control unit 24 and outputs it to the superimposing circuit 29. When the user operates (presses) the operation switch 13 of the endoscope 2, an operation signal is supplied to the control unit 24. When this operation signal is input, the control unit 24 controls the display controller 28 to change the size of the character information. In this way, the operation switch 13 constitutes an operation signal output unit that outputs an operation signal in accordance with a user operation.

The superimposing circuit 29 generates an endoscopic inspection image in which the character information from the display controller 28 is superimposed on the video signal (endoscopic image) from the video processing unit 27 and outputs the endoscopic inspection image to the display device 4. Thereby, an endoscopic examination image is displayed on the display device 4.

The touch panel 25 is, for example, a touch panel display in which a liquid crystal display (display unit 25a) and an electrostatic touch panel sensor arranged so as to overlap the liquid crystal display are integrated. On the touch panel 25, various settings of the endoscope system 1 and an operation screen for browsing recorded images are displayed. The user can view changes in settings and images of the endoscope system 1 by touching (pressing) the touch panel 25 with, for example, a finger.

An operation signal for operating the touch panel 25 is input to the control unit 24. The control unit 24 performs various settings of the endoscope system 1 according to operation signals input from the touch panel 25. More specifically, the reaction area when the user presses the operation button on the touch panel 25 with a finger or the like and the reaction area when the finger or the like is released (released) from the operation button is the same as the reaction area of the operation button. In this case, the control unit 24 determines that the release operation (button operation) is valid, and executes the function of the pressed operation button.

On the other hand, if the reaction area when the user presses an operation button on the touch panel 25 with a finger or the like and the reaction area when the finger or the like is released (released) from the operation button are not the reaction area of the same operation button, control is performed. The unit 24 determines that the release operation (button operation) is invalid and does not execute the function of the operation button. Thus, the control unit 24 configures a detection unit that detects a touch operation on the touch panel 25.

Also, the control unit 24 as a display control unit performs overall control of the touch panel 25 such as displaying an operation screen (menu screen) including operation buttons to be operated by a touch operation on the touch panel 25. In the present embodiment, the control unit 24 and the touch panel 25 constitute a touch panel device. Note that the touch panel 25 is a capacitive touch panel, but is not limited to a capacitive touch panel, and may be another type.

Here, the operation screen displayed on the touch panel 25 will be described. FIG. 3 is a diagram for explaining an example of an operation screen displayed on the touch panel 25.

As shown in FIG. 3, the operation screen displayed on the touch panel 25 displays a home button 40 for displaying a home screen, an image browsing button 41 for displaying an image browsing screen, and a setting change screen. The setting button 42 is provided. The operation screen shown in FIG. 3 is an image browsing screen displayed when the image browsing button 41 is pressed.

The internal memory button 43 is a button for displaying endoscopic image information recorded in the internal memory 26 of the video processor 3. The information on the endoscopic image is information such as the date and time when the endoscopic image is acquired, the patient ID, the patient name, and the transfer state.

The portable memory button 44 is a button for displaying information of an endoscopic image recorded in an external memory that is detachable from the video processor 3, that is, the recording medium 30. The information of the endoscopic image is information such as the date and time when the endoscopic image is acquired, the patient ID, the patient name, and the transfer state, as in the case of the internal memory button 43.

The information button 45 is a button for displaying memory information of the internal memory (memory 26) and the portable memory (recording medium 30). The user can display the memory information operation screen shown in FIG. 4 by pressing the information button 45.

FIG. 4 is a diagram for explaining an example of an operation screen for memory information. As shown in FIG. 4, the memory information includes information such as the number of examinations, the number of SD (Standard Definition) image recording, the number of HD (High Definition) image recording, the number of recordable images stored in the internal memory and the portable memory. It is. The user can return to the image browsing screen of FIG. 3 by pressing the close button 46.

Such a touch panel 25 has a reaction area that recognizes that various operation buttons have been operated. This reaction region will be described with reference to FIG. FIG. 5 is a diagram for explaining an example of a reaction area of various operation buttons according to the first embodiment.

Normally, the response area of an operation button is set to approximately the same size as the display area of the operation button. That is, as shown in FIG. 5, the reaction area of the home button 40 is set to a reaction area 47 that is substantially the same size as the display area of the home button 40.

On the other hand, the reaction area of the internal memory button 43 is preset by the control unit 24 in a reaction area 48 larger than the display area of the internal memory button 43. Similarly, the reaction area of the portable memory button 44 and the information button 45 is preset by the control unit 24 in a reaction area 49 and a reaction area 50 that are larger than the display area of the portable memory button 44 and the information button 45, respectively.

That is, the control unit 24 as the detection range setting unit expands a reaction area (operation detection range) that recognizes that the operation button has been operated by a touch operation, including the operation button area and a predetermined range from the area. Set to extended range.

Generally, it is recommended that the operation buttons have a predetermined height or more to prevent erroneous operation. Specifically, it is recommended that the predetermined height of the reaction region is, for example, 10 mm or more in consideration of the size of a general human finger.

For this reason, when the operation button is lower than the recommended predetermined height and no other operation button is arranged adjacent to the operation button, the reaction region is previously set in the direction in which the other operation button is not arranged. It is expanding. Since the internal memory button 43, the portable memory button 44, and the information button 45 have a height lower than a predetermined height and no other operation buttons are arranged on the upper part (that is, the reaction area of the other operation buttons on the upper part).

Reaction regions

48, 49, and 50 having an enlarged reaction region on the upper side are set in advance.

Further, when the height is equal to or higher than a predetermined height like the home button 40, the reaction region 47 is not enlarged. Even when the height of the operation button is lower than the predetermined height, if another operation button is arranged adjacent to the operation button, expanding the reaction area overlaps the reaction area of the other operation button. Therefore, do not enlarge the reaction area. As described above, in the touch panel 25 of the present embodiment, when the operation button is lower than a predetermined height and no other operation button is arranged adjacent to the operation button, the reaction area of the operation button is expanded in advance. Therefore, the inside of the reaction area cannot be reliably touched and the operation is prevented from being invalidated.

Another example of the reaction region enlarged in advance will be described with reference to FIGS. 6 and 7 are diagrams for explaining another example of the reaction region enlarged in advance.

FIG. 6 shows a selection screen of a function to be assigned to a switch operated by an operator such as the operation switch 13, and a button 60 for selecting a lamp ON / OFF switching function is arranged as this assigned function. . On this button 60, a character string representing the explanation of the button 60, here, a character string of “lamp” is displayed side by side.

In human behavioral psychology, when a button and a character string representing an explanation of the button are arranged side by side, the button is pushed closer to the character string side. In this case, if the reaction area is provided only on the button 60, the button operation may be invalidated when the user presses the button near the character string side.

Therefore, in the example of FIG. 6, a reaction region 61 larger than the button 60 is set in advance. Specifically, the reaction area 61 is enlarged so as to react up to the first character of the button 60 and a character string representing the description of the button 60.

In addition to the button 60, the switch information screen includes a button for assigning a white balance adjustment function to the operation switch, a button for assigning a function for brightening the image to the operation switch, and a function for darkening the image to the operation switch. These buttons are also arranged. Similarly, for these buttons, the reaction region is enlarged and set in advance.

Note that the reaction region enlarged in advance is not limited to FIG. As shown in FIG. 7, the reaction area 62 may be set in advance so as to react to all of the button 60, the button 60, and the character string representing the description of the button 60. Further, the reaction area 63 may be set in advance so as to react only to the character string representing the description of the button 60.

In this way, by setting the display related to the operation button (a character string representing the description of the operation button) as a reaction region, the user can perform an intuitive touch operation and improve operability. it can.

As described above, the touch panel 25 of the touch panel device has other operation buttons when the operation buttons (or reaction regions) are lower than a predetermined height and no other operation buttons are arranged adjacent to the operation buttons. The reaction region is enlarged in advance in the direction in which is not arranged. In addition, the touch panel 25 expands the reaction area in advance so as to include an operation button and a part or all of a character string related to the operation button. As a result, the touch panel device can prevent the user from pressing out of the reaction capacity range lower than the predetermined height or pressing out of the display area related to the operation button.

Therefore, the touch panel device according to the present embodiment and the endoscope system including the touch panel device can prevent the operation from being invalidated without reliably touching the inside of the reaction region.

(Second Embodiment)
Next, a second embodiment will be described.

In the first embodiment, the touch panel device and the endoscope system in which the reaction area of the operation button is enlarged in advance have been described. However, in the second embodiment, the touch panel apparatus in which the user enlarges the reaction area after pressing the operation button, and An endoscope system will be described. Note that the overall configuration of the endoscope system 1 is the same as that of the first embodiment, and control different from that of the first embodiment will be described below.

FIG. 8 is a diagram for explaining an example of a reaction region of various operation buttons according to the second embodiment, and FIG. 9 is a diagram for explaining an example of a reaction region in which an enlargement process is executed. 8 and 9, the same components as those in FIG. 5 are denoted by the same reference numerals and description thereof is omitted.

As shown in FIG. 8, in the second embodiment, the internal memory button 43 is set with a reaction area 80 having substantially the same size as the display area of the internal memory button 43. Similarly, the portable memory button 44 is set with a reaction area 81 having approximately the same size as the display area of the portable memory button 44, and the information button 45 has approximately the same size as the display area of the information button 45. A reaction area 82 is set.

Normally, the touch panel 25 validates the operation when the reaction area when the user presses the operation button with a finger or the like and the reaction area when the user releases the operation button are the same reaction area. That is, after the user presses the reaction area 80 of the internal memory button 43 with a finger or the like and slides the finger or the like outside the reaction area 80 while pressing the button, the operation is invalidated.

Therefore, when the user presses the internal memory button 43 with a finger or the like, the control unit 24 detects that the reaction region 80 is pressed from the operation signal (pressed coordinate signal). When detecting that the reaction area 80 of the internal memory button 43 has been pressed, the control unit 24 expands the reaction area 80 of the internal memory button 43 to the reaction area 84 as shown in FIG. In the example of FIG. 9, the control unit 24 sets the reaction region 80 to a reaction region 84 that is enlarged upward. Then, when the user releases (releases) a finger or the like from the touch panel 25, the control unit 24 validates the pressing of the internal memory button 43 when the coordinates where the release is detected are within the reaction region 84.

In addition, when the internal memory button 43 is pressed, the control unit 24 performs a process of enlarging the reaction area only on the upper side, but is not limited thereto. In general, when a certain operation button is pressed on the touch panel 25, only the reaction area of the operation button becomes valid, and the reaction areas of other operation buttons become invalid. For this reason, the reaction area of the pressed operation button may be enlarged so as to overlap the reaction area of another operation button.

For example, when the information button 45 is pressed by the user, the reaction areas of other operation buttons including the reaction area 47 of the home button 40 and the reaction area 81 of the portable memory button 44 are invalidated. Therefore, the control unit 24 may change the reaction area 82 of the information button 45 shown in FIG. 8 to a reaction area 85 that is enlarged in the vertical and horizontal directions as shown in FIG.

Further, the reaction area to be expanded is not limited to the reaction area of the operation button whose height is lower than the predetermined height as in the case of the internal memory button 43, and the control unit 24 allows the operation button having a predetermined height or higher to be selected. The reaction area may be enlarged. For example, after the user presses the home button 40, the control unit 24 may perform a process of expanding the reaction area 47 of the home button 40 in the left direction and the downward direction. Further, when the reaction area is provided in a range substantially equivalent to the display area of the button 60 in FIG. 6, the control unit 24 presses the button 60 in FIG. You may perform the process which expands a reaction area | region.

Next, the reaction area expansion processing executed by the control unit 24 will be described. FIG. 10 is a flowchart for explaining an example of the flow of the reaction region enlargement process.

First, the control unit 24 detects pressing of the operation button (step S1), and expands the reaction area of the operation button (step S2). Next, the control unit 24 detects the release of the operation button (step S3), and determines whether or not the coordinates where the release is detected are within the enlarged reaction region (step S4).

If it is determined that the coordinates where the release is detected are within the expanded reaction region, the determination is YES, and the control unit 24 determines that the release operation is valid and starts executing the button function (step S5). On the other hand, if it is determined that the coordinates where the release is detected are not within the enlarged reaction region, the determination is NO, and the control unit 24 determines that the release operation is invalid and does not execute the button function (step S6).

Finally, when the process of step S5 or step S6 is executed, the control unit 24 returns the enlarged response area of the operation button to the original size, and ends the process.

As described above, after the user presses the operation button, the touch panel device performs a process of enlarging the reaction area of the operation button more than the display area of the operation button. As a result, the endoscope system including the touch panel and the touch panel device according to the present embodiment can operate even when the user presses the operation button and then slides a finger or the like outside the original reaction area while pressing the operation button. It can be prevented from being invalidated.

It should be noted that each step in the flowchart in the present specification may be executed in a different order for each execution by changing the execution order and performing a plurality of steps at the same time as long as it does not contradict its nature.

The present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the scope of the present invention.

This application is filed on the basis of the priority claim of Japanese Patent Application No. 2015-167083 filed in Japan on August 26, 2015. The above disclosure is included in the present specification and claims. Shall be quoted.
