Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to an endoscope equipped with a light source device that outputs sequential light or white light depending on the endoscope or video processor to which it is connected. Regarding the system.

[Prior Art] In recent years, optical endoscopes (also called fiberscopes) that transmit an optical image formed by an objective lens at the distal end of the insertion section to the proximal side using an image guide formed by a fiber bundle have been developed. Instead, the optical image formed by the objective lens is converted into an electrical signal by a solid-state image pickup device such as a charge-coupled device (hereinafter referred to as COD), which is transmitted to the user's device, and the color image is transmitted via a video processor. 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 above-mentioned electronic scope is currently used for the upper or lower gastrointestinal tract, and is approximately 10 mm in diameter. However, for example, an endoscope for the bronchus usually requires an endoscope of around 5φ or less, and in order to realize an electronic scope for the bronchus (small diameter), an image sensor with a small number of pixels must be used. I don't get it.

When the number of pixels mentioned above is small, in order to prevent a decrease in resolution, illumination is performed in a sequential manner with light of each wavelength of red, blue, and green, rather than the color R image method using a color mosaic filter. A frame-sequential color imaging system is advantageous, in which images are conveyed in a frame-sequential manner, and these images are combined and displayed in color. on the other hand,
If the diameter can be made large, the number of pixels is large, and sufficient resolution can be obtained, mosaic color m using a mosaic filter can be used.
An image method may be used.

In the case of the above-mentioned electronic scope, in addition to the light source device used in the fiber scope, a video processor is used that processes signals and converts them into video signals that can be displayed on a color monitor.

By the way, in the conventional example, it is only used for fiber scopes or electronic scopes, and it is not possible to share the light source device for the fiber scope or the video processor and light source device for the electronic scope.

Furthermore, in electronic scopes, different signal processing needs to be performed for different color imaging methods, requiring respective video processors and light source devices.

For this reason, a system has been proposed in which an imaging adapter can be connected to a fiberscope and images can be displayed on a color monitor screen, as disclosed in, for example, Japanese Patent Application Laid-Open No. 60-243625.

In the above conventional example, when an imaging adapter is connected, it is possible to form an electronic scope that performs color m-images in a frame-sequential manner (integrating a video processor and a light source device).
When connected to the control device, the screen sequential I! Color display using images can be performed.

[Problems to be Solved by the Invention] The above system has a drawback in that a color mosaic electronic scope cannot be connected and used. Further, since only the above-mentioned frame sequential method can be used, it is desirable to use a color mosaic type electronic scope when photographing a moving subject, but it cannot be used selectively.

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

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 frame-sequential light or white light depending on an endoscope or video processor connected to the light source device. The goal is to create a system that is easy to use.

[Means and effects for solving the problem] In the present invention, a light source device capable of outputting white light and field-sequential light, and means for identifying a plurality of video processors with different scopes or signal processing to be connected are provided. The system is designed to be able to output white light or frame-sequential light depending on the scope or video processor connected to the system, making it an easy-to-use system that does not require an operation to switch the output light.

Incidentally, a light source connector 5A in each scope 2.

In this embodiment, 5B, 5C, 5D, and 5E are provided with air/water supply connectors as well as a light guide connector, and the connector receivers 11a and 11b are also structured to connect these.

The internal configurations of the scopes 2A, 28.2G, and 20.2E are shown in FIGS. 3, 4, and 5, respectively.

It is shown in FIGS. 6 and 7. A light guide 14 for transmitting illumination light is inserted through each scope 2, and the illumination light supplied from the light source section 15a or 15b in the imaging V4 main body 3 to the input end surface is transmitted to the output end surface side. The object side in front can be illuminated through a light distribution lens 16 placed in front of the camera.

Furthermore, in each scope 2, an objective lens 17 for imaging is arranged at the distal end of the insertion section 3. In the focal plane of this objective lens 17, C0D18 is arranged in the field-sequential type or color mosaic type double-tube scope 2A1 or 2B, while on the other hand, the fiberscope 2E, the TV camera 8C or 8D

A color mosaic filter 23 is disposed in front of the imaging surface of the CCD 18 or 22 used in the color mosaic type TV camera 8D. Each CCD 18 or 22 forming the imaging means photoelectrically converts the optical image formed on the imaging surface, and after being amplified by the preamplifier 24, it is sent to the signal connector 6 (6A) via the signal transmission line.

Representing 6B, 6G, and 60. ) side and the signal connector receiver 12a or 12b to which the connector 6 is connected
The signal is then input to a video processor 25a or 25b. Furthermore, each CGD 18 or 22 includes a video processor 25.
A CCD driving clock is applied from the driver 26a or 26b forming the driver 26a or 25b.

In addition, a type signal generation circuit 27A outputs a type signal for scope identification to scopes other than the fiber scope 2E.
, 27B, 27G, and 27D are provided, and are identified by an identification circuit 28a or 28b in the imaging device main body 3 via the signal connector 6.

By the way, the imaging device main body 3 which can be connected to any of the scopes 2 described above has two sets of light source sections 1 as shown in FIG.
5a, 15b, and two sets of video processors 25a, 25
b is stored.

One light source section 15a is of a field sequential type, and the white light from the light source lamp 31a is converted into R, G, and B illumination light through a rotating filter 33a rotated by a motor 32a.
The light is focused through the condensing lens 34a and the connector receiver 11
Illumination light is supplied to the incident end face of the light guide 14 attached to the a.

The other light source section 15b is a white light source, and is configured to condense white light from a white lamp 31b with a condensing lens 34b and guide it to the connector receiver 11b for the white light source. White light is supplied to the incident end face of the light guide 14.

By the way, one video processor 25a is for frame-sequential signal processing, and the signal input to the signal input terminal of the frame-sequential signal connector receiver 12a is input to the frame-sequential process circuit 41a. The signals captured under illumination light of each wavelength of R, G, and B are called color signals R, G.
, output as B. The color signals R, G, and B each pass through a driver formed by a buffer 42a, and are output as three primary color signals RGB from the three primary color output terminal 43a.

Further, the color signals R, G, and B pass through a matrix circuit 44a to generate a luminance signal Y and color difference signals R-Y and B-Y, which are then input to an NTSC encoder 45a and output to the NTSC encoder 45a.
The signal is converted into an SC composite video signal and output from the NTSC output terminal 46a.

A rotational position sensor 51a for detecting the rotational position is provided at one location on the outer periphery of the rotating filter 33a forming the field-sequential light source section 15a, and its output determines the clock timing of the timing generator 52a by the rotating filter 33a. The output of the timing generator 52a controls the timing of the frame sequential process circuit 41a.

This frame-sequential process circuit 41a has a configuration shown in FIG. 8, for example.

That is, the signal inputted via the preamplifier is inputted to the sample and hold circuit 54, sampled and held, and then subjected to γ correction in the γ correction circuit 55 and sent to the A/D converter 56.
is converted to digital data. Thereafter, the signals captured under sequential R, G, and B illumination through the multiplexer 57, which is switched by the signal from the timing generator 52a, are written to the R frame memory 58R, the G frame memory 58G, and the B frame memory 58B. be included.

The signal data written in each of these frame memories 58R, 58G, and 58B are simultaneously read out and converted into analog color signals R1G and B by a D/A converter 59, respectively.
The signal is output to the matrix circuit 44a described above.

On the other hand, C via the color mosaic signal connector 12b.
The signal captured by the CD 18 or 22 is input to a color mosaic process circuit 41b, and a luminance signal Y and color difference signals RY and BY are output. However, the signal is NT
The signal is input to the SC encoder 45b, converted into an NTSC composite video signal, and outputted from the NTSG output terminal 46b.

Further, the color signals R,
A buffer that is converted into G and B and forms a driver? 42b
The three primary color signals RG are output from the three primary color output terminals 43b through the three primary color output terminals 43b, respectively.
B is output.

Incidentally, the color mosaic process circuit 41b, for example, as shown in FIG.
The signal from 0D18 (or 22) passes through a brightness signal processing circuit 61 to generate a brightness signal Y. Further, the color difference signals R-Y and B-Y are inputted to the color signal reproduction circuit 62, and are generated time-series for each horizontal line, and white balance compensated by the white balance circuit 63. One of the signals is input directly to the analog switch 64, The other side is 1H daylay line 63a
analog switch 64 delayed by one horizontal line
a, and color difference signals RY and BY are obtained by switching signals from the timing generator 52b.

Note that each timing generator 52a, 52b is connected to a driver 26a, 26b and an NTSC encoder 4, respectively.
The details are such that signals are applied to 5a and 45b and signal processing is performed in synchronization with a drive pulse used for reading signals 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 rotational position sensor 51a. The NTSC encoders 45a and 45b are constructed with built-in buffers.

By the way, type signal generation circuit 27A, 278°270
．． 270 is formed, for example, by connecting resistors with different resistance values between two terminals, while the identification circuit 28a,
28b makes it possible to identify which resistance value scope is connected by using a Yombretor or the like to measure the resistance value between the two terminals.

For example, when the signal connector 6B or 6D of the color mosaic type electronic scope 2B or the color mosaic type fiber scope with TV camera 8D is connected to the frame sequential type signal connector receiver 12a, the resistance to the frame sequential type signal It is configured to identify that the value is not the same, operate the warning circuit 66a in response to the identified signal, and notify the user by making a warning sound with a buzzer, flashing an LED, or the like.

Also, when the connector 6A of the field-sequential electronic scope 2A or the connector 6C of the field-sequential fiberscope with TV camera 2C is connected to the color mosaic signal connector receiver 12b, the identification circuit 28b identifies it. The warning circuit 66b issues a warning.

On the other hand, when the connector 6A or 6C of the frame sequential type scope 2A or 2C is connected to the frame sequential type signal connector receiver 12b, no warning is given. (An LED may be lit to indicate that the connection is correct.) Similarly, when the connector 6B or 6D of the color mosaic scope 2B or 2D is connected to the color mosaic connector receiver 12b,
Warning circuit 66b does not operate. (It may be possible to identify that the connection is correct and indicate this by lighting an LED in a different position or in a different color than in the case of a warning.) Also, the connector receivers 12a and i2b for both signals may be A warning may also be issued when two signal connectors are connected at the same time. Further, a light source connector connection detecting means can be provided inside the field sequential light source connector receiver 11a, so that when the connector 5E of the second fiber scope is connected, it is possible to notify that it is an incorrect connection. That is, the light source side connector receiver 1
This is possible if the warning is issued when the connector 5E is connected to the connector 2a and neither connector is connected to the signal side connector receivers 11a and 11b.

According to a technical example related to the first embodiment configured as described above, the light source unit 15a and the frame sequential video processor 25a for a field sequential type scope, and the light source unit 15b for a color mosaic type scope and a color mosaic type scope. Since it has a video processor 25b and a connection means for each scope, it corresponds to any of the connected scopes, the frame sequential type scopes 2A, 2G and the color mosaic type scopes 2B, 2D. The scope can supply illumination light and perform signal processing, and can display the subject image captured by the scope in color on the color monitor 13.

Further, when using the fiber scope 2E, the light source connector 5E can be connected to the white light source connector receiver 11b, and in this way, observation with the naked eye can be performed.

On the other hand, two sets of connector receivers 1 provided on the main body 3 of the Il imager
If an incorrect scope is connected to 2a or 12b, the identification circuit 28a or 28b can detect that the connection is incorrect, and the warning circuit 66a or 66b can issue a warning.

Therefore, according to this related technology example, when one imaging device main body 3 is provided, it can be used with different scopes with different color imaging methods, and can also be used simultaneously with the fiber scope 2E. Furthermore, since a warning is given if an incorrect connection is made, the device is easy to use.

Furthermore, the output formats of the signals after signal processing are the same for the above two color imaging methods.

In other words, since they all match the three primary color output or the NTSC video signal, the same color monitor 1
3 can be used. (This color monitor may be one that supports three primary colors or one that receives an NTSC video signal.) Next, referring to FIG. One embodiment will be described below.

In addition, in this FIG. 1, the light source lamp 31a.

31b with only one of them, for example, 31b only.
The first embodiment corresponds to one in which the lamp can be switched between the position 1b and the position 31a, so that one lamp can provide both types of illumination as shown in FIG.

Also, a light source side connector receiver 71a' of the imaging device main body 101 forming the system of this first embodiment.

The signal connector receiver 72' common to the signal connector receiver 71/b' has the shape shown in FIG.
Both the connector 73A' of A and the connector 73B' of the mosaic electronic scope 2B can connect their respective signal connector parts to the common signal connector receiver 72', and the light source side connector parts are connected to the light source connectors provided above and below, respectively. It can be connected to the receivers 71a' and 71b'.

Similarly, the light source connector 74' and the signal connector 75A' of the scope 2C with a field-sequential TV camera or the connector 74 of the scope 2D with a mosaic TV camera.
The same applies to ', 75B'.

Furthermore, the connector 74' of the fiber scope 2E can be connected to the connector receiver 71b' on the white light source side.

The internal structure of the m-image device main body 101 is shown in FIG.

In the case shown in FIG. 1, the output signal of a type signal generating circuit (for example, 27A) that is input to a common identification circuit 28 via a common signal connector receiver 72' is connected by this identification circuit 28. Determine the scope. This identification circuit 28 not only controls both drivers 26a and 26b shown in FIG. 1, but also controls switching of a newly provided changeover switch 103. As shown in Fig. 1, the field sequential scope 2
When A or 2C is connected, it is switched to the field sequential side, and the drive pulse of the driver 26a is passed through the connector to C0D18.
The signal read out from the C0D 18 is input to the frame sequential processing circuit 418.

On the other hand, if the field sequential type scopes 2A and 2C are not connected, the mosaic type 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 handle either method.

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. output, while mosaic scope 2B
, 2D, and fiberscope>E output white light.

Further, in this embodiment, the signal that has passed through the process circuit 41a or 41b is input to an output circuit 80 shown in FIG. 11, for example. This output circuit 80 is an output circuit (equipped with a signal conversion function) in which the output terminals of the video processors 25a and 25b shown in FIG. 3 are shared.

That is, in FIG. 3, a three-circuit, two-contact changeover switch 81 is provided between the output end of the matrix circuit 44a and the NTSC encoder 458, and a buffer 42b forming a driver with the output end of the inverse matrix circuit 44b is provided. ,
A three-circuit, two-contact changeover switch 82 is also provided between the two terminals 42b and 42b.

When one contact side of the changeover switch 81 is turned on, the signal from the matrix circuit 44a is guided to the common NTSG encoder 45, and the NTSC encoder 45
Common NTSC output terminal 4 converted to SC video signal
Output from 6. When the other contact side is selected, the signal from the mosaic process circuit 41b is guided to the NTSC encoder 45 and output from the common NTSC output terminal 46.

On the other hand, regarding the other changeover switch 82, when the frame sequential type side is selected, the output signal of the frame sequential type process circuit 41a is transferred to the common buffer 42, 42, 42 forming a driver.
Three primary color signals are outputted from a common RGB output terminal 43 through the three primary color signals. Also, when the mosaic process circuit side is selected,
Three primary color signals R, G, B passed through the inverse matrix circuit 44b
are output from the common RGB output terminal 43.

The changeover switches 81 and 82 can be switched by identifying the type signal output from the scope 2 with the identification circuit 28.

Incidentally, when the changeover switches 81 and 82 are formed by an analog switch or the like, they can also be automatically changed over by a connection detection device 91 shown in FIG.

For example, a surface sequential type connector is provided with an identification bin 92 that is not provided in a mosaic type connector, and a surface sequential type connector receiver is provided with a recess into which the bin 92 can be inserted. Therefore, horizontal holes 93, 93 are provided on opposite sides of this recess,
A light emitting element 94 such as an LED and a light receiving element 95 such as a photodiode are arranged, and the output of the light receiving element 95 is sent to a detection circuit 96.
is input. When the light-receiving element 95 is inserted into the recess of the bottle 92, the light from the light-emitting element 94 is blocked and the light-receiving element 95
The output changes from °L to Hto, etc., and the detection circuit 96 detects this output change and switches the changeover switches 81 and 82 so that the plane sequential side is conductive. In addition, the light receiving element 94
If the output is "L", the color mosaic process circuit side may be selected.

According to this first embodiment, it has the same effect as that shown in FIG. 3, and the signal processing yIA system and the output light that can be used can be automatically selected depending on the connected squaw 12. This makes it easy to use.

Incidentally, instead of using the output circuit 80 shown in FIG. 11, it is also possible to use a structure in which the output terminals are separate for the frame-sequential type and the mosaic type as shown in FIG. 3.

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

Furthermore, in the first embodiment, for example, the lamp 31b may be moved to provide both types of illumination. Further, two light source lamps 31a and 31b are provided on both sides passing through the center of the rotary plate, and their positions can be exchanged (that is, the lamp 31a is placed in the position 31b, and the lamp 31b is placed in the position 31a) by rotational operation. Therefore, even if one lamp burns out, the other lamp can be used as an auxiliary light.

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

For example, on the front surface of the housing of the imaging device main body 131 in the second embodiment, a common light source connector receiver 71 is provided, as shown in FIG. A mosaic type signal connector receiver 72b is provided.

On the other hand, the connector 132A of the field-sequential electronic scope 2△ and the connector 132B of the color mosaic electronic scope 2B
Both of the light source connector parts can be attached to the light source connector receiver 71, and each signal connector part can be connected to the field sequential type connector receiver 72a and the color mosaic type connector receiver 72b, respectively. Although not shown in FIG. 14, the same applies to electronic scopes 2G and 2D equipped with frame-sequential and mosaic TV cameras. Further, the fiber scope 2E can be observed with the naked eye by connecting its connector to the light source connector receiver 71.

In the imaging device main body 131 shown in FIG. 13, the rotating filter section 133 is connected to the rail 134 as shown in an enlarged view in FIG.
．． It is movable along 134.

The rotary filter section 133 is usually mounted on a rail 134.1.
For example, as shown in FIG. 15, the rotating filter 33a is retracted from the optical path of the light source lamp 31 and the lens 34, and the white light source section is formed. Become. On the other hand, when the rotary filter section 133 is moved from this state to the lower side of the rails 134, 134, it is interposed in the optical path as shown in FIG. 13, and a field-sequential light source section is formed.

By the way, the rotary filter section 133 is connected to the movement control circuit 1.
The movement is controlled by the movement control circuit 1
35 is activated by the identification signal from the identification circuit 28a. In this embodiment, when the type signal generated by the type signal generation circuit 27A1 or 27G identifies that the scope is a field sequential type scope, the identification circuit 28a outputs a movement control command to the movement control circuit 135, and the rotation filter unit 133 is moved from the state shown in FIG. 15 to the state shown in FIG. 13.

On the other hand, when the mosaic scope 2B or 2D connector is connected, the rotary filter section 133 is not moved.
White light is provided. Also, when the fiberscope 2E is attached, white light is supplied to the connector of the fiberscope.

In addition, after the field sequential set scope 2A or 2C is installed,
When removed, the rotating filter section 133 is returned to the state where it is retracted from the optical path.

The rest of the structure is the same as that shown in FIG.

According to this second embodiment, since the light source section is shared,
Field-sequential or mosaic type scopes can be handled without providing two sets of light source units. Furthermore, when connecting a fiberscope connector, having two light source connector receivers can prevent erroneous connections such as erroneously connecting to the side of the field-sequential type, making it easier to use.

Note that the rotary filter section 133 may be moved manually.

FIG. 16 shows an imaging device main body 1 in a third embodiment of the present invention.
41 is shown.

In the second embodiment, the rotating filter section 133 is movable, but in this embodiment, the light source section 142 is movable along the rails 143, 143.

For example, the connector receiver on the front side of the imaging device main body 141 of this embodiment has a structure as shown in FIG. 17, and the connector on the scope side also has the shape shown in the same figure.

In the imaging device main body 141, a round field-sequential light source connector receiver 71a and a signal connector receiver 72a, a white light source connector receiver 71b, and a color mosaic signal connector receiver 72b are provided spaced apart on the front surface of the housing, etc. be. Both connector receivers 71a, 71b and 72a, 7
2b have the same shape as each other.

On the other hand, as shown in FIG. 17(a), the field sequential type scope 2A includes a connector receiver 71a for a field sequential type light source.

A connector 73A is provided in which a light source connector portion and a signal connector 74 portion are integrated so that it can be connected to the signal connector receiver 72a.

Similarly, the color mosaic type scope 2B is shown in Fig. 17 (
As shown in b), a connector 73B is provided which can be connected to the white light source connector receiver 71b and the color mosaic signal connector receiver 72b.

Furthermore, as shown in FIG. 17(a), the field-sequential TV camera equipped fiber scope 2C has the same shape as the connector 73A of the field-sequential electronic scope 2A when the light source connector 74 and signal connector 75A are combined. It can be used by connecting to the surface sequential type connector receivers 71a and 72a.

In addition, as shown in Figure 17(b), a color mosaic TV
Fiberscope 2D with camera also has light source connector 7
4 and the signal connector 75B can be combined to have the same shape as the connector 73B of the color mosaic electronic scope 2B, and can be connected to the white light source connector receiver 71b and the signal connector receiver 72b.

In addition, by connecting the light source connector 74 of the fiber scope 2E to the white light source connector receiver 72b, white light can be supplied to the light guide of the fiber scope 2E, allowing observation with the naked eye.

By the way, the light source section 142 in the imaging device main body 141 usually has a white light source connector receiver 71 as shown in FIG.
When the field-sequential scope 2A or 2C is connected to the inside of the frame b, the identification circuit 28a identifies it based on its type signal, and the movement control circuit 1
35 (moved downward in FIG. 18, moved to the left in FIG. 17), and as shown in FIG. The R, G, and B illumination lights that have passed through the rotary filter 33a are supplied to the light source connector portion of the formula.

By the way, the m-image device main body 141 of this embodiment has the 16th
As shown in the figure, unlike the one shown in FIG. 13, a shared output circuit 113 is used.

The specific configuration of this output circuit 113 is shown in FIG.

This output circuit 113 is an output circuit 80 having a signal conversion function as shown in FIG. The circuit is set to 113. Although the other changeover switch 82 shown in FIG. 11 is not provided, it may be provided.

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

The rest is the same as that shown in FIG. 11 above.

According to this embodiment, edge enhancement is performed in common for different luminance signals of two methods, so the number of parts is reduced compared to when two sets are provided for each method. It is possible and the configuration is easy.

In addition, it can be made cost-effective.

The rest of the structure is the same as that shown in Fig. 13 above.
It has the same effect as Habo.

Incidentally, in the third embodiment, the connector receiver can also be structured to be movable together with the light source section 142. In this case, when the mosaic type scope 2B or 2D is connected, it does not move, but when the frame sequential type scope 2A or 2C is connected, it is moved. Note that the fiber scope 2E is not moved.

In this case, there is only one connector receiver.

This embodiment can also be structured to be moved manually.

FIG. 20 shows an imaging device main body 1 in a fourth embodiment of the present invention.
51 main parts are shown.

In this embodiment, in FIG.
, which illuminates with R, W, and B instead of B.

I have to.

The rotary filter 152 used for sequentially illuminating the surface with the R, W, and B illumination lights has a fan-shaped window section provided in a disc-shaped filter frame 153, as shown in FIG. R
, W, passing through B.

The color transmission filters 154R, 154W, and 154B of B are attached. This W transmission filter 154W has R, G,
This is a filter that allows B to pass through. (Incidentally, a transparent plate may be used to allow all of the white light to pass through.) In addition, the R, W, and B color transmission filters 154R, 154W,
154B, the length of the arc shape is adjusted according to the photosensitive characteristics of the CCD 18 or 22 so that the illumination period is different.

The filter frame 153 is provided with RlW, B color transmission filters 154R, 154W, 154B (rotational direction
1. :f! l) Read pulse (detection) holes 155R and 155W near the ends, respectively.

155B is provided. These read pulse holes 155
The positions of R, 155W, and 155B are photo sensors 156 that are arranged opposite to each other so as to sandwich the light emitting element and the filter frame 153.
When the light emitting element reaches a position opposite to the light emitting element, the light from the light emitting element is received in a pulsed manner by the photosensor 156, thereby detecting the light emitting element. When this pulsed light is detected, a detection signal is transmitted to the timing generator 52a, and the driver 26a
Alternatively, a read drive pulse is applied to the CCD 18 or 22 via 26b.

The filter frame 153 has, for example, a read pulse hole 1.
A start pulse hole 157 is provided at a position adjacent to 55R in the radial direction, and when this position reaches a position facing the 7th sensor 158, the photosensor 158 outputs a start pulse.

Further, in order to detect the position of the W color transmission filter 154W, an arcuate long hole 159 is formed at the outer circumferential position of the color transmission filter 154W.
By detecting this with the photosensor 160, the position of the W color transmission filter 154W can be detected. Therefore, the output of this photosensor 160 controls the stop position of the rotary filter 152. In other words, when the motor 32a that rotationally drives the rotary filter 152 is not in a rotational driving state, the output of the photosensor 160 is adjusted such that the stopped position of the rotary filter 152 is a position where the elongated hole 159 faces the photosensor 160. It is input to the rotation/stop control device 161 and controls the stop position of the rotary filter 152. In this stopped position state, the illumination light from the light source lamp 31 passes through the W color transmission filter 154W and faces the light source connector receiver 71, so that white illumination light can be supplied. It should be noted that when a 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 (in both of these states, the identification circuit detects a high impedance state). This white illumination state occurs when a mosaic scope is connected.

On the other hand, when the frame-sequential scope is connected, the identification circuit 28 detects the connection and outputs a command signal to the rotation/stop control @path 161 to drive the motor 32a.
2a is rotated to bring it into a sequential illumination state.

In addition, this example rha 11ml1il! Main body 151 (7)
The connector receiver 71 for light lj is commonly used for white light and for surface sequential light. Further, the signal connector receiver is commonly used for both the field sequential type and the mosaic type, as shown in FIG. 22, for example. In Figure 22, two electronic scopes 2A
, 2B is shown, but other scopes 2G, 20.2E
But you can connect.

Incidentally, in this embodiment, since the frame sequential illumination light is not R2O, B, the frame sequential process circuit 162 has a configuration as shown in FIG. 23, for example.

That is, in the process circuit 41a shown in FIG. 8, the G frame memory 58G is replaced with a W frame memory 58W (although the memory contents are different, the station frame memory can be used in terms of hardware), and The W color signal read from the W frame memory 58W and converted into an analog signal by the D/A converter 59 is input to the subtracter 163.
A G color signal is generated by subtracting the R color signal and the R color signal. The rest is the same as the process circuit 41a shown in FIG.

The imaging device main body 151 shown in FIG. 20 is the same as that shown in FIG. 1 in other respects.

According to this embodiment, both the frame-sequential type and the mosaic type use the same light source, and they can be used simply by connecting a scope, making them easy to use. Further, there is no need to newly provide a moving means for moving the light source section or the rotary filter section, and thus 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 embodiment, R and W in the case of sequential illumination.

B, but it is not limited to this, for example, R, G, WOW, G, B・;Cy (cyan)
, Ye (yellow), W: C'/, W, MQ (magenta): W
, Ye, MO, etc. can also be used.

FIG. 24 shows the vicinity of a rotary filter section 170 in a fifth embodiment of the present invention.

In this embodiment, the filter frame 171 has R and G colors.

In addition to B color transmission filters 172R, 172G, and 172B, for example, R and B color transmission filters 172 are provided.
A white illumination hole 173 is provided in the light-shielding portion between R and 172B, and this hole 173 connects to a light-shielding plate 174 that is rotatably attached to a position midway through a line connecting the hole 173 and the center. It is designed to block light.

That is, when the filter frame 171 is rotated by the motor 32a, the light shielding plate 174 is
As shown in FIG. 25, the direction connecting the center position of the disc-shaped light shielding part and the pivot point coincides with the radial direction, and in this state, the hole 17
3 is now blocked by the light shielding plate 174, and the normal R, G, B
It is possible to perform surface sequential illumination.

On the other hand, when stopped, the centrifugal force does not work, so 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 source lamp and the lens 34 in the stopped state. The filter frame 171 has a large number of holes 175, 175, .
In addition, 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 photosensor 176 is attached to the tip of a plate 177.

Incidentally, the entire apparatus of this embodiment has a structure shown in FIG. 26, for example.

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 field-sequential electronic scope 2A has a light source connector and a signal connector integrated into one, and the light source connector receiver 1 of the Il imaging device main body 182.
83 and the surface sequential type connector receiver 184a.

On the other hand, the fiberscope 2E can be observed with the naked eye by connecting its connector 185 to the light source connector receiver 183, and, for example, by attaching a mosaic type TV camera 8D to the eyepiece 7, a mosaic type T camera-equipped scope can be used. and signal connector 1 of this mosaic TV camera 8D.
86 can also be used by connecting it to the mosaic type signal connector receiver 187.

Although not shown in FIG. 26, it can also be used with a mosaic type electronic scope 2B, or with a fiber scope 2E connected to a frame sequential type TV camera 8C.

Incidentally, the internal configuration of the imaging device main body 182 is such that the light source section 142 and its control circuit system shown in FIG. 16 are replaced with the light source section shown in FIG. It is almost the same as the one in which the R, G, and B side sequential lights and the white light can be outputted by replacing it with , and these are arranged as shown in FIG. 26.

For example, a frame-sequential video processor has a box-like housing 18.
8, and a housing 189 housing a mosaic video processor is disposed on the upper surface of the housing 189. Note that a frame memory 19 forming a frame sequential video processor
0 is also disposed on the top surface of the housing 188. The color monitor 13 is connected to the signal output ends of both housings 188 and 189 via a signal cable.

Incidentally, inside the light source connector receiver 183, a filter frame 171 forming the rotating filter section 170 and the light source lamp 31 are arranged.

FIG. 27 shows a rotary filter section 1 of a modification of the fourth embodiment.
70' is shown.

This rotary filter 170' has a concave lens 180 attached to the hole 173 of the filter frame 171 shown in FIG. 24 above.

The concave lens 180 defocuses the illumination light that is focused on the end face of the ride guide fiber during illumination with white light to prevent the light guide fiber from burning out. Note that when the concave lens 180 is not inserted, that is, when the light is passed through a filter, the light guide fiber is focused at the end face. In this case, since the light is attenuated by the filter, the end face of the light guide fiber is almost never burnt out. In addition, concave lens 1
The lens 34 and the light source lamp 31 are moved in the optical axis direction (on the rail) without interposing the 80, and the defocus state is set when illuminating with white light, and the focus state is set when illumination is performed by field sequential illumination. You can also do it.

FIG. 28 shows the external shape of the sixth embodiment of the present invention.
Figure 9 shows the combined state of the field sequential type scope, and the 30th
The figure shows the combination of mosaic scopes.

In this embodiment, the imaging device main body 191 is composed of a light source section 192 which is separated and shared, and a frame sequential video processor section 193a or a mosaic video processor section 193b shown in FIG. As shown in FIG.
A light source connector receiver 194 is provided at the lower front side of the video processor section 92, and each video processor section 193a or 193b
A signal connector receiver 195 is provided on the upper front side of the , and both connector receivers 194 and 195 are connected to the light source section 19 on the upper surface of the video processor section 193a or 193b.
2 (one video processor section 193a is shown in FIG. 28), they are arranged so that they are vertically adjacent to each other.

On the other hand, the connector 197 of the field-sequential electronic scope 2A
The light source connector part and the signal connector part are integrated! As shown in FIG. 28, when the light source section 192 and video processor section 193a are placed in an overlapping state, they can be connected to both connector receivers 194 and 195.

On the other hand, for example, the mosaic type electronic scope 2B has a connector divided into a light source connector 198 and a signal connector 199, and the connectors 198 and 199 can be connected to connector receivers 194 and 195, respectively. Further, for example, for the fiberscope 2C with a field sequential TV camera, the light source connector 198 and the signal connector 200 can be connected to the connector receivers 194 and 195, respectively.

By the way, the light source section 192 has a configuration similar to that of the light source section in FIG. 13. Note that the lens 34 in FIG. 13 is two lenses 34' and 34 in this embodiment.
' I have to.

This light source section 192 has a connector receiver 203 to which one of the connectors 202 of the cable 201 is connected in order to send timing pulses of the timing generator 52a to the separate frame-sequential video processor section 193a.
Similarly, a frame sequential video processor section 19 is provided.
3a is also provided with a connector receiver 203.

Further, the light source section 192 is provided with a connection detection circuit 204 that detects whether the connector 202 of the signal cable 201 is connected to the connector receiver 203, and as shown in FIG. 29, when the cable 201 is connected, The output of this circuit 204 outputs a movement command signal to the movement control circuit 135, and the rotating filter section 133 is moved along the rails 134, 134, and the rotating filter 33a is interposed in the middle of the illumination optical path to perform field-sequential illumination. We are making it possible to do this.

On the other hand, a connection detection circuit 205 is also provided in the frame sequential video processor section 93a to detect whether the connector 202 of the cable 201 is connected to the connector receiver 203, and the output of this detection circuit 205 is input to the warning circuit 66a. be done. Therefore, when the identification circuit 28a detects that the field sequential scope 2A or 2C is connected, the warning circuit 66a connects the connection detection circuit 205 to the cable 201.
When a detection signal indicating that is not connected is input,
Warning buzzer 20 that the cable 201 is not connected
6a and a warning light 207a. A warning is also given when the signal connector 199 of the mosaic scope 2B or 2D is connected to the signal connector receiver 195.

In the cable 201, the timing pulse from the light source section 192 is outputted as a control signal to a driver etc. via a pulse generator 208 in the video processor section 93a. The rest of the configuration is the same as that shown in FIG. 13.

Furthermore, a mosaic video processor section 19 shown in FIG.
The configuration of 3b is similar to that shown in FIG.

The video processor section 193b includes an identification circuit 28b.
A warning circuit 66b is provided which operates with the output of the mosaic signal connector receiver 195.
When the signal connector of the field-sequential scope 2A or 2C is connected to the
b or a warning light 207b to warn you. The rest of the configuration is the same as that shown in FIG. 13.

Note that when the mosaic scope 2B or 2D or the fiber scope 2E is connected, the rotating filter section 133 is not moved, and therefore the white light from the light source lamp 31 is focused and irradiated onto the connector 198 through the lens 34. be done.

Although FIG. 29 shows a state in which the field-sequential electronic scope 2B is connected, its connector 197 is separated for convenience.

In the above embodiment, even if the connector is integrated as in the case of the field-sequential scope 2A, the mosaic scope 2A
Even if they are separated like in case B, they can be connected.

In FIG. 28, the light source and signal connectors 197 of the field-sequential electronic scope 2A are integrated, but they may be separated as in the case of the mosaic electronic scope 2B. Conversely, the connectors 198 and 199 of the mosaic electronic scope 2B may be integrated.

Note that the connection detection circuits 204, 205, etc. described above are not necessarily required. Further, in the above embodiment, the rotary filter section 13
3 is movable, but the lamp 31 and the connector receiver 195 may also be movable.

Also, video processor? A signal for increasing or decreasing the light m of the lamp 31 may be sent from the 193a and 193bll to the light source section 192 via a signal line (not shown) to automatically adjust the light.

FIG. 31 shows a modification of the light source section 192 in the sixth embodiment.

The light source section 192' of this embodiment uses the rotary filter 152 shown in FIG. 20 as the rotary filter of the rotary filter 8I+ 133 of FIG. 29, and does not have a movable structure.
Rotation/stopping is controlled by a rotation/stopping control circuit 161 (see FIG. 20). In this case, a field sequential process circuit 162 shown in FIG. 23 is used instead of the field sequential process circuit 41a shown in FIG. 29. This embodiment has substantially the same functions as the sixth embodiment.

Incidentally, a rotary filter section 170 shown in FIG. 24 may be used instead of the rotary filter 152. In this case, a field sequential process circuit 41a shown in FIG. 29 can be used.

FIG. 32 shows a seventh embodiment of the present invention.

In this embodiment, the light source section 211 is not shown in FIG.
92', the timing generator 52a is not provided, but a shared timing generator 52 is used in the shared video processor section 212. In addition, when illuminating in sequence, the connection detection circuit 204 detects whether the cable 2
01 is not connected, a warning can be given by a buzzer 206 or by lighting a lamp 20-7.

The video processor section 212 is as shown in FIG.
Similar to the sixth embodiment, a connection detection circuit 205', a buzzer 213 driven by a company announcement circuit 66, and a warning light 214 are provided. This connection detection circuit 205' has the same function as the connection detection circuit 205 shown in FIG. 29 in the sixth embodiment.

The buzzer 213 and the warning light 214 are operated by the output of the identification circuit 28, and both identification circuits 28 of the sixth embodiment
It has the same function as the operation by a and 28b.

The rest of the structure is the same as that of the sixth embodiment.

According to this embodiment, since the video processor section 212 is shared, the number of constituent units of the entire system can be reduced, which is convenient when moving the system.

Furthermore, since at least a part of the signal processing system is shared and used, the number of component parts can be reduced and costs can be reduced.

Note that an output circuit 113 shown in FIG. 19 may be used instead of the output circuit 80 having a signal conversion function in the above embodiment.

FIG. 33 shows the structure of an eighth embodiment of the present invention, and FIG. 34 shows its external shape.

The imaging device main body 131 shown in FIG. 34 is provided with a light source connector receiver 134 that is shared with the frame sequential signal connector receiver 133a so that the connector 132 of the frame sequential electronic scope 2A can be connected. Can be displayed in color. The connectors (as shown) of the fiberscope 2C with a frame-sequential TV camera can also be connected to the connector receivers 133a and 134 for use.

Also, in the case of fiberscope 2E, its connector 1
35 can be connected to the light source connector receiver 134 for observation with the naked eye.

The light source section inside the light source connector receiver 134 is normally capable of outputting white light, for example as shown in FIGS. It is useful.

In the above-mentioned field sequential illumination, when the field sequential signal connector is connected to the field sequential signal connector receiver 133a, the rotary filter is rotated by the type signal output at that time, resulting in field sequential illumination.

By the way, a recess is provided in the lower front side of the IIl image device main body 131, so that the mosaic preprocessor unit 137 can be plugged in and installed. A mosaic signal connector receiver 133b is provided on the front surface of the mosaic preprocessor unit 137, and a signal connector 138 of the mosaic TV camera 8D can be connected to the connector receiver 133b, and a signal connector of the mosaic electronic scope 2B can be connected to the connector receiver 133b. A connector (not shown) can also be connected.

As shown in FIG. 33, inside the imaging device main body 131,
A light source unit similar to that shown in FIG. 20 is housed, as well as a frame sequential processor. This frame-sequential processor is almost the same as that selected when the switch 103 is switched to the frame-sequential side in the processor shown in FIG.
The output circuit 113 shown in the figure is provided with a function of performing signal processing for contour enhancement.

The changeover switch 81' in the output circuit 113 provided with this signal processing means can be switched when the mosaic preprocessor unit 137 is plugged in.

According to this embodiment, if a mosaic preprocessor unit 137 is installed later as needed, it can also be used with a mosaic scope, and the functions of the device can be expanded economically.

In addition, even when the mosaic type preprocessor unit 137 is plugged in, a changeover switch SW is provided, for example, on the front surface of the device main body 131 so that the screen sequential type and mosaic type can be used. The changeover switch 81' is designed to be able to be changed by ID.

In the seventh embodiment, the plug-in unit can be installed on the front side, but a mosaic video processor unit or a part thereof can be inserted into the expansion slot provided on the rear side, etc., and the above switch can be installed. It is also possible to use SW or the like for both field-sequential type and mosaic type scopes.

[Effects of the Invention] As described above, according to the present invention, since the light is switched to frame sequential light or white light depending on the scope or video processor connected to the light source device, the user does not have to perform a switching operation. It is possible to realize a system that is necessary and easy to use.
