Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an endoscope provided with a light source device which is switched to output field sequential light or white light according to an endoscope or a video processor to be connected. Regarding the system.

[Related Art] In recent years, an optical endoscope (also referred to as a fiberscope) that transmits an optical image formed by an objective lens at a distal end portion of an insertion portion to a hand side by an image guide formed of a fiber bundle. Instead, the optical image formed by the objective lens is photoelectrically converted by a solid-state imaging device such as a charge-coupled device (hereinafter, referred to as a CCD), converted into an electric signal, and transmitted to the hand side. Electronic endoscopes (hereinafter, also referred to as electronic endoscopes or electronic scopes) that can be displayed on a monitor have come into practical use.

The electronic scope is currently used for the upper or lower digestive tract, and the one with a diameter of about 10φ is used. However, for example, an endoscope for bronchus usually requires a diameter of about 5φ or less, and in order to realize an electronic scope for bronchus (small diameter), an image pickup device with a small number of pixels must be used. I don't get.

In the case where the number of pixels is small, the light is illuminated in a plane-sequential manner with light of each wavelength of red, blue, and green, rather than a color imaging method using a color mosaic filter, in order to prevent a decrease in resolution. It is advantageous to use a frame-sequential color imaging system in which frame-sequential imaging is performed by using the above-described method, and these are combined and displayed in color. On the other hand, when the diameter can be made large and the number of pixels is large and sufficient resolution can be obtained, a mosaic color imaging method using a mosaic filter may be adopted.

In the case of the electronic scope, in addition to the light source device used in the fiber scope, a video processor that performs signal processing to generate a video signal that can be displayed on a color monitor is used.

By the way, in the conventional example, only the fiberscope or the electronic scope is dedicated, and the light source device for the fiberscope or the video processor and the light source device for the electronic scope cannot be shared.

Also, in an electronic scope, different signal processing has to be performed in different color imaging methods, and each video processor and light source device have been required.

For this reason, a system has been proposed in which an image pickup adapter can be connected to a fiberscope and displayed on a color monitor screen as disclosed in, for example, JP-A-60-243625.

The above-mentioned conventional example is capable of forming an electronic scope for performing color imaging of a frame-sequential system when an image pickup adapter is connected. Color display can be performed.

[Problems to be Solved by the Invention] The above system has a drawback that a color mosaic type electronic scope cannot be connected and used. or,
Since it can be dealt with only by the frame-sequential method, it is desirable to mount and use the color mosaic electronic scope for a subject having a function, but it cannot be selectively used.

The present invention has been made in view of the above points, and an object of the present invention is to provide an endoscope system that can be used for different color imaging systems.

Another object of the present invention is to provide a light source device capable of outputting frame-sequential light and white light with means capable of outputting field-sequential light or white light according to an endoscope or a video processor connected thereto. , To realize a user-friendly system.

[Means and Actions for Solving Problems] In the present invention, a light source device capable of outputting white light and field sequential light and a connecting means or an identifying means for a plurality of video processors having different signal processings are provided and connected.

By the way, as shown in FIG. 3, the imaging device main body 3 which can be connected to any of the above scopes 2 has two sets of light source parts.
15a and 15b and two sets of video processors 25a and 25b are housed.

One of the light source units 15a is of a frame sequential type, and white light of a light source lamp 31a is rotated by a motor 32a.
After being converted into illumination light of R, G, B through 33a, a condenser lens 34a

The other light source unit 15b is a white light source, and the white lamp 3
The white light of 1b is condensed by the condenser lens 34b and guided to the white light source connector receiver 11b, and white light is supplied to the incident end face of the light guide 14 mounted on the connector receiver 11b.

By the way, one video processor 25a is for a frame sequential signal processing, and has a connector for a frame sequential signal.
The signal input to the signal input terminal of 12a is input to the frame-sequential process circuit 41a, and the signals imaged under the illumination light of each wavelength of R, G, B are color signals R, G, Output as B. Thus, the color signals R, G, B are respectively stored in the buffer 42a.
A three-primary-color signal RGB is output from the three-primary-color output terminal 43a via the driver formed in step (1). The chrominance signals R, G, B pass through a matrix circuit 44a to generate a luminance signal Y and chrominance signals RY, BY, which are then input to an NTSC encoder 45a and
The video signal is converted into a composite video signal of the C system and output from the NTSC output terminal 46a.

A rotary position sensor 51a for detecting a rotary position is provided at one location on the outer periphery of the rotary film 33a forming the frame sequential light source unit 15a, and the timing of the clock of the timing generator 52a of the output thereof is set to the rotary filter 33a. This timing generator 52a is synchronized with the rotation of
Output controls the timing of the frame sequential color process circuit 41a.

The frame sequential color process circuit 41a has, for example, the configuration shown in FIG.

That is, the signal input through the preamplifier is input to the sample-hold circuit 54, sample-held, and then γ-corrected by the γ-correction circuit 55 and converted into a digital amount by the A / D converter 56. After that, the multiplexer 57 which can be switched by the signal of the timing generator 52a.
Signals imaged under R, G, B frame sequential illumination via
It is written in the R frame memory 58R, the G frame memory 58G, and the B frame memory 58B. Each of these frame memories 58R, 58
The signal data written in G and 58B are simultaneously read out, converted into analog color signals R, G and B by the D / A converter 59, respectively, and output to the matrix circuit 44a side described above.

On the other hand, CCD through the color mosaic type signal connector 12b
The signal captured at 18 or 22 is input to the color mosaic process circuit 41b, where the luminance signal Y and the color difference signals R-Y, B-
Y is output. Then, the signal is the NTSC encoder 45b.

The color mosaic color process circuit 41b has a CCD1 amplified by a preamplifier 24 as shown in FIG. 9, for example.
The signal from 8 (or 22) passes through a luminance signal processing circuit 61 to generate a luminance signal Y. Further, the color signal reproduction circuit 62 is inputted, the color difference signals RY and BY are generated in time series for each horizontal line, and white balance compensation is performed by the white balance circuit 63. One of them is directly input to the analog switch 64.

Is obtained.

The timing generators 52a and 52b apply signals to the drivers 26a and 26b and the NTSC encoders 45a and 45b, respectively, and perform control so as to perform signal processing in synchronization with a driving pulse used for signal reading from the CCD 18 or 22. in this case,
In the frame sequential video processor 25a, the timing generator 52a is synchronized with the rotation filter 33 by the output of the rotation position sensor 51a. The above NTSC
The encoders 45a and 45b are configured with built-in buffers.

By the way, the type signal generation circuits 27A, 27B, 27C, 27D
For example, the resistors having different resistances are connected between the two terminals, and the identification circuits 28a and 28b are connected to the scope having any resistance by using the resistance between the two terminals using a comparator or the like. It is possible to identify whether or not.

Thus, for example, the color mosaic type electronic scope 2B or the color mosaic type
Signal connector 6B of fiberscope 8D with TV camera or
When 6D is connected, it identifies that the resistance value is not the resistance value for the frame sequential type, activates the warning circuit 66a according to the identified signal, and notifies the user by a buzzer warning sound or LED blinking. It is like that.

Also, when the connector 6A of the frame sequential electronic scope 2A or the connector 6C of the fiber scope 2C with the frame sequential TV camera is connected to the color mosaic signal connector receiver 12b, the identification circuit 28b identifies the connector. Then, a warning is issued by the warning circuit 66b.

On the other hand, when the connector 6A or 6C of the frame-sequential scope 2A or 2C is connected to the frame-sequential signal connector receiver 12b, no warning is given. (If the connection is correct, the LED may be turned on to display.) Similarly, when the color mosaic type connector receiver 12b is connected to the connector 6B or 6D of the color mosaic type scope 2B or 2D, a warning circuit 66b. Does not work. (It is also possible to identify that the connection is correct and display that by a lighting of an LED of a different color or a different position from that in the case of the warning.) Also, 2 in both signal connector receivers 12a, 12b.
The warning may be issued even when two signal connectors are connected at the same time. Further, the connection detection means of the light source connector is provided inside the frame sequential light source connector receiver 11a,
When the connector 5E of the fiberscope 2E is connected, it can be notified that the connection is incorrect. That is, it is possible to give a warning when the connector 5E is connected to the light source side connector receiver 12a and neither connector is connected to the signal side connector receivers 11a and 11b.

According to the technical example related to the first embodiment configured as above, the light source unit 15a for the frame sequential type scope and the video processor 25a for the frame sequential type, the light source 15b for the color mosaic type scope and the color mosaic type Video processor 25b
And, since the connection means for each scope is provided, even if any of the frame-sequential scopes 2A, 2C and the color mosaic type scopes 2B, 2D are connected, the illumination light corresponding to the connected scope Can be supplied and signal processing can be performed, and the subject image captured by the scope can be displayed in color on the color monitor 13.

Further, when the fiberscope 2E is used, the light source connector 5E can be connected to the white light source connector receiver 11b, which allows visual observation.

On the other hand, two sets of connector receivers 12 provided on the imaging device body 3 are provided.
When an incorrect scope is connected to a and 12b, the identification circuit 28a or 28b can detect that the connection is not correct, and the warning circuit 66a or 66b can issue a warning.

Therefore, according to this related art example, if the single image pickup device main body 3 is provided, it is possible to cope with scopes having different color image pickup systems, and to use the fiberscope 2E at the same time. In addition, since a warning is given when an incorrect connection is made, the device is easy to use.

The output format of the signals after signal processing for the two color imaging systems is the same. In other words, the same color monitor 13 can be used because both are matched with the three primary color output or the NTSC system video signal.
(This color monitor may be one that supports three primary colors or one that receives an NTSC video signal.) Next, the first one that has almost all the functions of the above related technology example.
A first embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, only one of the light source lamps 31a and 31b, for example, only 31b is provided so that the position of 31b and the position of 31a can be switched and shown, and one lamp is shown in FIG. The one that can perform both types of illumination as described above corresponds to the first embodiment.

Further, a signal connector receiver 72 'common to the light source side connector receivers 71a' and 71b 'of the image pickup apparatus main body 101 forming the system of the first embodiment has, for example, the shape shown in FIG. The connector 73A 'of the sequential scope 2A or the signal connector receiver 72' common to the connector 73B 'of the mosaic electronic scope 2B can be connected to the respective signal connector portions, and the light source side connector portions are provided above and below, respectively. It can be connected to the light source connector receivers 71a ', 71b'. Similarly, the same applies to the light source connector 74 'and the signal connector 75A' of the scope 2C scope 2C with a TV camera or the connectors 74 ', 75B' of the mosaic TV camera scope 2D. Further, the connector 74 'of the fiberscope 2E can be connected to the connector receiver 71b' on the white light source side.

 FIG. 1 shows the internal configuration of the image pickup apparatus main body 101.

As shown in FIG. 1, for example, the output signal of the type signal generating circuit (for example, 27A) inputted to the common discrimination circuit 28 via the common signal connector receiver 72 'is the discrimination circuit 2
Determine the scope connected in step 8. This identification circuit 28
In addition to controlling both drivers 26a and 26b shown in FIG.
The switching of the newly provided changeover switch 103 is controlled. When the frame-sequential scope 2A or 2C is connected as shown in FIG. 1, it is switched to the frame-sequential side, and the drive pulse of the driver 26a is applied to the CCD 18 via the connector and the CCD 18
The signal read from is input to the frame sequential process circuit 41a.

On the other hand, if the frame sequential scopes 2A and 2C are not connected,
The mosaic process circuit side is selected. Incidentally, the case of the mosaic type scope 2B or 2D may be detected and the changeover switch 103 may be switched to the mosaic type side.

The identification circuit 28 also sends a control signal to the shared timing generator 52 so that it can deal with any of the methods.

In the first embodiment, in the configuration shown in FIG. 1, the identification circuit 28 identifies the connected scope 2 and moves, for example, the light source lamp 31b. In the case of the frame sequential scopes 2A and 2C, the field sequential light is used. On the other hand, in the case of the mosaic type scopes 2B and 2D and the fiberscope 2E, white light is output.

Further, in this embodiment, the signal passed through the process circuit 41a or 41b is input to the output circuit 80 shown in FIG. 11, for example.
The output circuit 80 is a video processor 25a, shown in FIG.
It is an output circuit in which the output end of 25b is shared (having a signal conversion function).

That is, in FIG. 3, a buffer switch 42b, 42b forming a driver with the output terminal of the inverse matrix circuit 44b is provided by providing a switch 81 having three circuits and two contacts between the output terminal of the matrix circuit 44a and the NTSC encoder 45a. , 42b is also provided with a three-circuit, two-contact changeover switch 82.

When one of the contact sides is turned on, the changeover switch 81 guides the signal of the matrix circuit 44a to a common NTSC encoder 45, and the NTSC encoder 45 converts the signal to an NTSC video signal and outputs it from the common NTSC output terminal 46. To do. When the other contact side is selected, the mosaic process circuit 41

Output from 6.

On the other hand, for the other changeover switch 82, when the frame-sequential side is selected, the output signal of the frame-sequential process circuit 41a passes through the common buffers 42, 42, 42 forming a driver, and the common RGB output terminals 43 to 3 The primary color signal is output. When the mosaic process circuit side is selected, the three primary color signals R, G, B that have passed through the inverse matrix circuit 44b are output from the common RGB output terminal 43.

The changeover switches 81 and 82 can switch the type signal output from the scope 2 by discriminating it by the discrimination circuit 28.

When the changeover switches 81 and 82 are formed by analog switches or the like, they can be automatically changed over by the connection detecting device 91 shown in FIG.

For example, a frame-sequential connector is provided with an identification pin 92 that is not available in the mosaic-type connector, while a frame-sequential connector receptacle is provided with a recess into which the pin 92 can be engaged. Then
Lateral holes 93, 93 are provided on opposite sides of the concave portion, and a light emitting element 94 such as an LED and a light receiving element 95 such as a photodiode are arranged. The output of the light receiving element 95 is input to a detection circuit 96. When the light receiving element 95 is engaged with the pin 92, the light emitting element 94
Light is blocked and the output of the light receiving element 95 changes from "L" to "H" and the like, and the detection circuit 96 detects this change in output and switches the changeover switches 81 and 82 so that the frame sequential side is conductive. When the output of the light receiving element 94 is "L", the color mosaic type process circuit side may be selected.

According to the first embodiment, it is possible to select the one which has the same effects as those shown in FIG. 3 and which can automatically use the signal processing system and the output light depending on the connected scope 2. It is possible and easy to use.

Incidentally, without using the output circuit 80 shown in FIG.
As shown in the figure, the output end may be different between the frame sequential type and the mosaic type.

Alternatively, the output circuit 80 shown in FIG. 11 may be used to manually switch the changeover switches 81 and 82.

Further, in the first embodiment, for example, the lamp 31b may be moved so that both types of illumination can be performed. Also, two light source lamps 31a and 31b are provided on both sides passing through the center of the rotating plate, and the positions of the lamps can be exchanged (that is, the lamp 31a is located at the position 31b and the lamp 31b is located at the position 31a) by a rotating operation. If one of the lamps burns out, the other lamp may be used as an auxiliary lamp.

FIG. 13 shows an image pickup apparatus main body according to the second embodiment of the present invention, in which the light source connector portion is shared.

As shown in FIG. 14, a common light source connector receiver 71 is provided on the front surface of, for example, the housing of the image pickup apparatus main body 131 in the second embodiment, and the frame sequential signal connector receiver 72a and the collar are symmetrically provided on both sides thereof.

The white light source section is formed. On the other hand, when the rotary filter unit 133 is moved to the lower side of the rails 134, 134 from this state, it is inserted in the middle of the optical path as shown in FIG. 13 to form a frame sequential light source unit.

Incidentally, the rotation filter unit 133 is provided with a movement control circuit 135.

In this embodiment, when the type signal is generated by the type signal generation circuit 27A or 27C, it is discriminated that the scope is a frame-sequential scope. The discrimination circuit 28a outputs a movement control command to the movement control circuit 135, and the rotary filter unit. 133 is moved from the state shown in FIG. 15 to the state shown in FIG.

On the other hand, when the connector of the mosaic type scope 2B or 2D is connected, the rotating filter unit 133 is not moved, and white light is supplied. Further, even when the fiberscope 2E is attached, white light is supplied to the connector of the fiberscope.

In addition, when the surface-sequential type scope 2A or 2C is attached and then removed, the rotary filter unit 133 is returned to a state of being retracted from the optical path.

 Others are the same as the configuration shown in FIG.

According to the second embodiment, since the light source unit is shared, it is possible to deal with the frame-sequential type or mosaic type scope without providing two sets of light source units. In the case of connecting the connector of the fiberscope, if there are two light source connector receivers, it is possible to prevent erroneous connection that is erroneously connected to the side-by-side type, and it becomes easy to use.

The rotary filter unit 133 may be manually moved.

It can be formed in the same shape as the A connector 73A, and can be used by connecting to the frame sequential connector receivers 71a, 72a.
As shown in FIG. 17 (b), the fiber mosaic 2D with color mosaic type TV camera has the same shape as the connector 73B of the color mosaic electronic scope 2B when the light source connector 74 and the signal connector 75B are combined. It is possible to connect to the white light source connector receiver 71b and the signal connector receiver 72b.

Further, by connecting the light source connector 74 of the fiberscope 2E to the white light source connector receiver 72b, white light can be supplied toward the ride guide of the fiberscope 2E, and the naked eye can be observed.

By the way, the light source unit 142 in the imaging device
As shown in FIG. 18, when the field-sequential scope 2A or 2C is connected in the state of facing the inside of the white light source connector receiver 71b and the same as in the second embodiment, the discrimination circuit 28a is caused by the type signal. The light source section is identified and moved through the movement control circuit 135.
142 (moved to the lower side in Fig. 18 and moved to the left side in Fig. 17) and moved to the frame-sequential connector receiver as shown in Fig. 16.
The R, G, and B illumination lights that have passed through the rotary filter 33a are supplied to the frame-sequential light source connector portion that faces the inside of 71a.

By the way, as shown in FIG. 16, the image pickup apparatus main body 141 of this embodiment uses a shared output circuit 113, unlike that shown in FIG. The concrete structure of the output circuit 113 is shown in FIG.

This output circuit 113 is an output circuit having a signal conversion function shown in FIG. 11, which outputs a luminance signal switched by the changeover switch 81 to the contour emphasizing circuit 112 to perform contour emphasizing signal processing. I am at 113. still,
Although the other changeover switch 82 shown in FIG. 11 is not provided, it may be provided.

The changeover switch 81 may be changed over by the output of the identification circuit 28 shown in FIG. 1 or may be changed over manually.

 Others are the same as those shown in FIG. 11 above.

According to this embodiment, since the contour enhancement is performed in common for the luminance signals of the two different systems, the number of partial points is smaller than in the case where two sets are provided for each system. It is possible and the configuration is simple. Also, it is possible to reduce the cost.

Others are the same as those shown in FIG. 13 above,
It has almost the same effect.

In the third embodiment described above, it is possible to have a structure in which the connector receiver can be moved together with the light source unit 142. In this case, it does not move when the mosaic type scope 2B or 2D is connected, but moves in the case of the frame sequential type scope 2A or 2C. It is not moved in the case of the fiberscope 2E. In this case, there is only one connector receiver.

This embodiment can also be configured to move manually.

FIG. 20 shows an image pickup apparatus main body 15 according to the fourth embodiment of the present invention.
1 shows the main part.

In this embodiment, as shown in FIG.
We illuminate with R, W, B instead of B.

The rotary filter 152 used for certifying the frame order with the R, W, and B illumination light is provided with a fan-shaped window portion in the disc-shaped filter frame 153 as shown in FIG. 21, and each window portion has R, W, B color transmission filters 154R, 154W, 154B that pass through R, W, B are attached. The W transmission filter 154W is a filter that passes R, G, and B. (Note that the white light may be all transmitted through an approximately transparent plate.) The R, W, and B color transmission filters 154R, 154W, and 154B are CCD18.
Alternatively, the arcuate length is adjusted so that the certification period varies depending on the photosensitivity characteristic of 22.

The filter frame 153 has a color transmission filter 154 of R, W, B so that a read time immediately after illumination by each of R, W, B can be detected.
Read pulse (detection) holes 155R, 155W, 155B are provided near the ends of the R, 154W, 154B (with respect to the rotation direction A). The positions of these lead pulse holes 155R, 155W, 155B are
When the photosensor 156 reaches a position facing the photosensor 156 disposed so as to face the light emitting element with the filter frame 153 therebetween, the light can be detected by the photosensor 156 receiving the light of the light emitting element in a pulse shape. When the pulsed light is detected, a detection signal is transmitted to the timing generator 52a, and a driving pulse for reading is applied to the CCD 18 or 22 via the driver 26a or 26b.

In the filter frame 153, for example, a read pulse hole 155 is provided.
A start pulse hole 157 is provided at a position radially adjacent to R, and when this position reaches a position facing the photosensor 158, the photosensor 158 outputs a start pulse.

Further, in order to detect the position of the W color transmission filter 154W, a long hole 159 is formed in an arc shape at a position on the outer side in the circumferential direction of the color transmission filter 154W, and the long hole 159 is detected by the photo sensor 160. The W color transmission filter 154W
Position can be detected. Thus, the output of the photo sensor 160 controls the stop position of the rotary filter 152. That is, when the motor 32a that rotationally drives the rotary filter 152 is not in the rotational drive state, the rotational filter 152
The output of the photosensor 160 is input to the rotation / stop controller 161 so that the stop position of the filter 162 is located at a position where the long hole 159 faces the photosensor 160, and the stop position of the rotary filter 152 is controlled. In this stopped position state, the illumination light of the light source lamp 31 passes through the W color transmission filter 154W, faces the light source connector receiver 71, and white illumination light can be supplied. When the fiberscope is connected to the connector receiver 71 and nothing is connected to the connector receiver 72, or when nothing is connected to the connector receivers 71 and 72,
(These two states can be identified by the identification circuit detecting the high impedance state.) Or, when the mosaic type scope is connected, this white illumination state is established.

On the other hand, when the frame sequential scope is connected, the connection is detected by the identification circuit 28, and a command signal for driving the motor 32a to rotate is output to the rotation / stop control circuit 161 to rotate the motor 32a to perform the frame sequential. Turn on the lighting.

In this embodiment, the light source connector receiver 71 of the image pickup apparatus main body 151 is used in common for white light and for frame sequential use. Further, the signal connector receiver is commonly used by, for example, a frame sequential type and a mosaic type as shown in FIG. No. 22
Although two electronic scopes 2A and 2B are shown in the figure, other scopes 2C, 2D and 2E can be connected.

By the way, in this embodiment, since the frame sequential illumination light is not R, G, B, the frame sequential process circuit 162 has a structure as shown in FIG. That is, in the process circuit 41a shown in FIG. 8, the G frame memory 58G is replaced with the W frame memory 58W (the same frame memory can be used in terms of hardware although the memory contents are different), and the W frame memory Read from memory 58W, D / A converter
The W color signal converted into an analog signal in 59 is input to a subtractor 163, and the R color signal and the B color signal are subtracted to generate a G color signal. Others are the same as those of the process circuit 41a shown in FIG.

The image pickup apparatus main body 151 shown in FIG. 20 is the same as that shown in FIG. 1 in other respects.

According to this embodiment, the light source unit is shared by both the frame-sequential type and the mosaic type, and it can be used by simply connecting a scope, which is convenient. Further, it is not necessary to newly provide a moving means for moving the light source unit or the rotary filter unit,
The cost can be reduced and the size can be reduced.

In the above embodiment, the light source connector means and the signal connector means are shared, but the signal connector means may not be shared.

Further, in the above-mentioned embodiment, in the case of frame sequential illumination, R, W, B are used, but the present invention is not limited to this. For example, R, G, W; W, G, B; Cy (cyan ), Ye (yellow), W; Cy, W, Mg (magenta); W, Ye, Mg, etc. can also be used for illumination.

FIG. 24 shows the rotary filter section in the fifth embodiment of the present invention.

That is, when the filter frame 171 is rotated by the motor 32a, the light-shielding plate 174 has a radial direction in which the center position of the disc-shaped light-shielding portion and the pivot point are connected by the centrifugal force, as shown in FIG. Hole 173 in this state
The state is interrupted at 74, and normal R, G, B plane sequential illumination can be performed.

On the other hand, when stopped, the centrifugal force does not work, so that the light shielding plate 174 is retracted from the hole 173 by gravity as shown in FIG.

The position of the filter frame 171 is controlled so that the hole 173 is on the optical axis connecting the light ray lamp and the lens 34 in the stopped state. C for position control or R, G, B plane sequence
A plurality of holes 175, 175 ... Are provided in the filter frame 171 in the circumferential direction for detecting the timing of reading the CD signal, and a light emitting element and a photosensor 176 are arranged on both sides of the plate surface of the filter frame 171 to form a rotary encoder for position detection.

In FIG. 24, the photo sensor 176 is attached to the tip of the sensor attachment plate 177.

By the way, the entire apparatus of this embodiment has, for example, the structure shown in FIG.

FIG. 26 shows, for example, a frame sequential electronic scope 2A, a fiberscope 2E, and a mosaic TV camera 8D that can be connected to the fiberscope 2E.

The connector 181 of the frame sequential electronic scope 2A is one in which the light source connector and the signal connector are integrated, and is connected to the light source connector receiver 183 and the frame sequential connector receiver 184a of the imaging device body 182. You can

On the other hand, the fiber scope 2E can connect the connector 185 to the light source connector receiver 183 to perform visual observation. For example, a mosaic type TV camera 8D can be attached to the eyepiece 7 to provide a scope with a mosaic type TV camera. The signal connector 186 of the mosaic-type TV camera 8D can be connected to the mosaic-type signal connector receiver 187 for use.

Further, although not shown in FIG. 26, the mosaic type electronic scope 2B can be used, and the fiber scope 2E to which a frame sequential TV camera 8C is connected can also be used.

By the way, as for the internal structure of the image pickup apparatus main body 182, the light source unit 142 and its control circuit system shown in FIG. 16 are replaced with the light source unit shown in FIG. 20, and the filter unit is replaced with a rotary filter unit 170 having the reference numeral shown in FIG. The arrangement is almost the same as that for outputting the R, G, B frame sequential light and the white light, and these are arranged as shown in FIG.

For example, a frame sequential video processor has a box-shaped housing 18

The concave lens 180 defocuses the illumination light focused on the end surface of the light guide fiber when illuminated with white light so that the light guide fiber is not burned. In addition, when the concave lens 180 is not interposed, that is, when the concave lens 180 is passed through, a focus is made on the end face of the ride guide fiber. In this case, since the light is dimmed by the filter, the end face of the light guide fiber is hardly burned. In addition, concave lens 180
