Detailed Description

Fig. 1 is a configuration diagram of an endoscope system. Fig. 2 is a block diagram of an endoscope system.

The endoscope system of the present invention includes a processor 30 having a built-in light source unit 40 and an internal viewer (endoscope) 10 inserted into the body of an examination object. The internal viewer 10 can be removably connected to the processor 30. The processor 30 is further connected with a keyboard, a display, a touch screen, an external light source device 90, and the like.

As shown in fig. 1, in the interior viewer 10, the cable 10C extending from the operation portion 10P to the processor 30 side has two branches: an electrical connection portion 10S and an optical connection portion 10L. The electrical connection portion 10S is connected to the processor 30. One end of the light connecting portion 10L is connected to the light source devices 90 and 110. In fig. 2, the other end of the optical connector 10L is connected to a light source unit 40 built in the processor 30. The light source device and the processor are connected to a computer 210, which are capable of communicating with each other.

The light source unit 40 includes a xenon lamp (xenon lamp) 82, and the xenon lamp 82 can be lighted by power supplied from the power supply 82. The light emitted from the xenon lamp 82 enters the incident end 11A of the light guide 11 through the condenser lens 83. The light guide 11 is provided inside the internal viewer 10. The light emitted from the emission end 11B after passing through the light guide unit 11 is irradiated from the interior viewer distal end portion 10T to the subject (observation target) via the light distribution lens 13. A diaphragm 84 is provided between the xenon lamp 82 and the light guide 11.

The light reflected by the subject is imaged by an objective lens 14 provided at the distal end portion 10T of the internal viewer, and an image of the subject is formed on the light receiving surface of the image sensor 12. The image sensor 12, which is configured by a CMOS sensor, a CCD, or the like, reads pixel signals for one frame at predetermined time intervals (for example, at intervals of 1/60 seconds or 1/30 seconds) driven by the driving circuit 17. A color filter assembly (not shown) is disposed on the light receiving surface of the image sensor 12. The color filter combination is configured by arranging color filters of Cy, Ye, G, Mg, R, G, B, or the like in a matrix.

The pixel signal read from the image sensor 12 is input to the analog signal processor 15 via the amplifier AP, and predetermined signal processing is performed. In the signal processing circuit 32 in the preceding stage of the processor 30, image signal processing such as white balance processing, gamma correction processing, and the like is performed on the pixel signal. Thereby generating R, G, B an image signal.

R, G, B the image signal is temporarily stored in the image memory 33 and then sent to the subsequent-stage signal processing circuit 34. In the subsequent signal processing circuit 34, edge emphasis processing, superimposition processing, and the like are applied to the image signal. When the image signal is output to the monitor 60 as a video signal, an observation image is displayed on the monitor 60.

The control unit 35 includes a CPU, a ROM, and the like, and outputs a control signal to the post-stage signal processing circuit 34 by the timing generator 36, and controls the operation of the processor 30 when the processor 30 is in a power-on state. The operation control program is stored in advance in the memory 37 such as the ROM.

When the internal viewer 10 is connected to the processor 30, the controller 35 performs interactive communication with the viewer controller 16 that controls the operation of the internal viewer 10, and stores data (resolution, internal viewer type, and the like) relating to the characteristics of the internal viewer stored in the nonvolatile memory 19 in a RAM or the like.

The timing generator 36 of the processor 30 outputs a clock signal to the processor 30, for example, the circuits of the pre-signal processing circuit 32, and controls the input and output timings of each circuit to be adjusted. On the other hand, the clock pulse signal output from the timing generator 18 of the video endoscope 10 is input to each circuit of the drive circuit 17 of the video endoscope 10.

The controller 85 of the light source unit 40 calculates a luminance value indicating the luminance of the subject image based on the image signal obtained by the processor 30, and automatically performs the light control process. Here, the luminance of the subject image is increased or decreased by the electronic shutter function. On the other hand, the diaphragm 84 may be used for automatic dimming, or the operator may adjust the aperture of the diaphragm 84 to a predetermined value by operating a brightness controller on the operation device 39. The controller 85 controls a motor 87 for driving the diaphragm 84 through a motor driver 86.

The operation device 39 of the processor 30 has an operation panel. The operating device 39 may be an external device or may be integral with the processor 30. The operation device 39 is preferably a touch device (e.g., a touch panel), and may be other input/output devices. The processor is connected with an operation device, and an operator outputs an operation instruction to the processor through the operation device.

As shown in fig. 3, a plurality of function buttons (marks) can be displayed on the operation device. The plurality of function buttons include at least a brightness adjuster to adjust a brightness level at the time of an automatic dimming process; a white balance adjuster (described later) for performing tone adjustment, and the like. When it is necessary to switch between different light sources or to set light source parameters, the operation device 39 may be provided with a light source controller or the like.

The light source devices 90, 110 are each connected to the processor 30. The light source devices 90, 110 are different types of light sources from the xenon lamp 82 built in the processor 30. The flash 92 and the LED 112 are provided in the light source devices 90 and 110, respectively. The controller 95 of the light source device 90 and the controller 115 of the light source device 110 receive instructions for controlling light source switching from the processor 30 via the I/F circuit 99 and the I/F circuit 119, respectively, thereby controlling the lighting and extinguishing of the flash 92 and the LED 112.

The light source device 90 includes a power source 91, a condenser lens 93, an aperture 94, a motor driver 96, a motor 97, and a memory 98. The light source device 110 includes a power source 111, a condenser lens 113, an aperture 114, a motor driver 116, a motor 117, and a memory 118.

The operator can select the connection port for inserting the light connection portion 10L into any one of the light source portion 40, the light source device 90, and the light source device 110 as necessary, and can set the parameters of the internal viewer 10 and the processor 30 according to the selected light source by operating the light source adjuster provided in the operation device 39.

When the operator operates the operation device 39, the sensor built in the operation device 39 detects contact information at different touch positions and transmits a signal to the processor 35. The processor 35 determines a white balance adjustment indication based on the contact information of the different positions detected by the sensor.

The white balance adjuster WB is long. Sensors are fully distributed at the lower part of the long-strip-shaped white balance adjuster WB, and the sensors can sense contact modes of touch, light point, double click, light scanning and the like of the white balance adjuster.

Example 1

Fig. 3 shows a configuration diagram of an operation panel in the operation device 39. The operation panel includes a brightness adjuster, a light source adjuster, a white balance adjuster for performing tone adjustment, and the like. In the present embodiment, the white balance adjuster is located at the lower right corner of the operation panel, and the white balance adjuster WB may be provided at other positions of the operation panel as needed.

The long white balance adjuster WB has three position reading portions: not implemented, time difference and implemented (completed). The long white balance adjuster WB has three or more sensors at a lower portion thereof. The three position reading parts respectively correspond to at least one sensor and can detect whether the corresponding positions are touched. The three position reading portions are arranged in parallel.

When the sensor built in the operation device 39 detects that the white balance adjuster is lightly swept in an arbitrary position as a whole, the white balance adjuster enters a "white balance task standby" state, and the white balance adjustment mode is started. If there is no subsequent operation, the white balance adjuster is in a standby state. If further swipe is detected in the standby state, the position sensor detects which of the three position reading sections the position being swiped at.

In the standby state, if the position sensor detects that the "unfinished" position reading unit has been swiped and the operation panel displays that the cursor stays at the "unfinished" position shown by a in fig. 4, the white balance adjustment is temporarily not performed, the white balance unfinished state is maintained, and the white balance adjustment is finished.

If the position sensor detects that the "time difference" position reading section is swiped in the standby state, the operation panel displays that the cursor stays at the "time difference" position shown in b in fig. 4, indicating that the "time difference mode" white balance adjustment mode is about to be entered. After the cursor stays at the "time difference" position, if the sensor detects that the "time difference" position is double-clicked within a predetermined time (for example, 2 seconds or 3 seconds), this time difference white balance adjustment command is canceled, and the operation panel displays that the cursor stays at the "unfinished" position shown by a in fig. 4, white balance adjustment is temporarily not performed, and the white balance unfinished state is maintained, and white balance adjustment is ended. After the cursor stays at the "time difference" position, if the sensor does not detect that the "time difference" position is double-clicked within a predetermined time (for example, 1 second, 2 seconds, or 3 seconds), the controller 35 transmits a white balance adjustment command to the internal viewer 10, starts white balance adjustment, enters a "time difference mode" white balance adjustment mode, gradually moves the cursor from the "time difference" position to the "implementation (completion)" position as shown in c in fig. 4, and after a certain time, moves the cursor to the "implementation (completion)" position shown in d in fig. 4, and at the same time, completes white balance adjustment.

If the position sensor detects that the "done (done)" position reading unit is swiped in the standby state, the controller 35 transmits a white balance adjustment command to the internal viewer 10 to perform the white balance adjustment mode, and the cursor stays at the "done (done)" position as shown by d in fig. 4.

Example 2

The configuration of the operation panel in the operation device 39 is still as shown in fig. 3. The operation panel includes a brightness adjuster, a light source adjuster, a white balance adjuster for performing tone adjustment, and the like. In the present embodiment, the white balance adjuster is located at the lower right corner of the operation panel, and the white balance adjuster WB may be provided at other positions of the operation panel as needed. In contrast, in this embodiment, the cursor of the white balance adjuster is always displayed in the middle of the elongated white balance adjuster WB.

At least one sensor is arranged below the middle position of the cursor at the lower part of the strip-shaped white balance adjuster WB. More than one sensor is respectively arranged at the left and the right by taking the middle part as the center. Therefore, at least three sensors are provided at the lower portion of the white balance adjuster WB, and the three sensors are arranged in parallel. When any one of the sensors built in the lower portion of the white balance adjuster WB detects that the white balance adjuster is lightly swept, the white balance adjuster WB enters a "white balance task standby" state, and starts a white balance adjustment mode. If there is no subsequent operation, the white balance adjuster is in a standby state. If in the standby state, a further swipe is detected, the lower sensor determines the direction of the swipe.

In this embodiment, the swipe direction includes: "left sweep", "right sweep", and "non-left and right sweep". The left-hand sweep is that at least two sensors at the lower part of the white balance adjuster WB read contact successively, and the contact is judged to move from right to left according to the successive sequence. The right-hand sweep is that at least two sensors at the lower part of the white balance adjuster WB read contact successively, and the contact is judged to move left and right according to the sequence. Non-left-right sweeping means that the sensor at the lower portion of the white balance adjuster WB detects a movement of the contact neither from left to right nor from right to left.

When the lower sensor determines that the sweep in the standby state is "left sweep", it indicates that the instruction given by the operator is to enter the white balance adjustment mode of the "time difference mode". The cursor at the center of the white balance adjuster WB is displayed in a first color (for example, blue), and if the sensor detects that the white balance adjuster WB is double-clicked within a predetermined time (for example, 1 second, 2 seconds, or 3 seconds), this time difference white balance adjustment command is cancelled, and the operation panel displays the cursor in a second color (also referred to as a normal color, for example, white), and the white balance adjustment is temporarily not performed, and the white balance non-performing state is maintained, and the white balance adjustment is terminated. After the cursor is displayed in the first color, if the sensor does not detect double-click within a predetermined time (for example, 1 second, 2 seconds, or 3 seconds), the controller 35 transmits a white balance adjustment command to the internal viewer 10 to start white balance adjustment, enters a "time difference mode" white balance adjustment mode, and after a predetermined time, the cursor is displayed in a third color (for example, green) and white balance adjustment is completed. In the mode in which the white balance adjustment is performed in the "time difference method", the cursor may continuously blink while the white balance adjustment is performed, and after the white balance adjustment is completed, the blinking may be stopped, and the display may be fixed to the third color.

When the lower sensor judges that the sweep in the standby state is "right sweep", it indicates that the instruction given by the operator is to directly perform white balance adjustment. The cursor is displayed in the third color directly or after flashing for a certain time. The white balance adjustment is ended.

When the lower sensor determines that the contact in the standby state is neither "left swipe" nor "right swipe", the processor 35 determines that the operator has instructed not to perform white balance adjustment, and the cursor is displayed in a second color (also referred to as a normal color, for example, white), and ends the white balance adjustment.

Example 3

As shown in fig. 5, the elongated white balance adjuster has four position reading portions: non-implementation, time difference, standby mode a (b), and implementation (completion). At least three sensors are provided for each position reading section centering on each area to detect the direction of the swipe in which the cursor is touched. In each area corresponding to the position reading unit, the plurality of sensors in the area are distributed with the geometric center of the area as the center. In this embodiment, the swipe direction includes: "left sweep", "right sweep", "up (down) sweep". The left-hand sweep is that at least two sensors horizontally arranged at the lower part of the white balance adjuster WB read contact successively, and the contact is judged to move from right to left according to the successive sequence. The right-hand sweeping means that at least two sensors horizontally arranged at the lower part of the white balance adjuster WB read contact successively, and the contact is judged to move left and right according to the sequence. The up (down) sweep refers to that two sensors arranged up and down at the lower part of the white balance adjuster WB read contact sequentially, and whether the contact is a top-down sweep or a bottom-up sweep is judged according to the sequential order.

In a state where there is no white balance adjustment instruction, the cursor is in an unimplemented position. When the operator scans the cursor lightly, the direction of the cursor is determined according to the direction of the light scanning, and the cursor is moved to a position reading part corresponding to the indication.

For example, when the sensor provided left and right determines that the sweep of the cursor is a left sweep, white balance adjustment in the time difference mode is performed. The cursor is moved to a time difference position. When the sweep is right-handed, white balance adjustment is immediately performed, and the cursor is moved to the position of execution (completion). When the sweep is an upward or downward swipe, other white balance adjustment modes may be set.

According to the utility model discloses, the operator can be through simple operation from multiple white balance adjustment mode, the required white balance adjustment mode of direct selection, and is very simple and convenient, is fit for the operation of various endoscopes. And because the parameters of each mode do not need to be set after the white balance adjustment mode is selected, and the time for pressing the button does not need to be waited, the checking efficiency is obviously improved, and the time is saved.
