Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an endoscope device for observing the inside of a body cavity.

[0002]

2. Description of the Related Art Generally, an endoscope apparatus for observing the inside of a body is equipped with a processor for an endoscope having a light source section and an image processing section, and is inserted into the body to illuminate an observation site and simultaneously perform imaging. It is composed of a scope and. In endoscopic observation in recent years, it is of course possible to simply observe the observation site and the surroundings of the observation site while continuously irradiating light (hereinafter referred to as “normal imaging”) as well as the observation site. In order to use it as a diagnostic material by observing the desired moment state on a monitor or recording it on a recording medium such as a film, it is necessary to capture a freeze image of the observed region at the desired moment (hereinafter, freeze). Called imaging) is also required. Therefore, as the processor, a processor including a light source most suitable for an observation site to be imaged, an imaging method thereof, and the like is appropriately selected and used.

For example, in the case of performing normal imaging to roughly grasp the state around the observation site, a processor equipped with a normal light source that can constantly illuminate is required.
Further, when freeze imaging is performed and only a specific shape of the observed region is extracted and imaged, a processor equipped with a strobe light source capable of intermittent light emission is required.

Thus, there is a problem that it is extremely troublesome for the operator to use a different processor each time the method of imaging the observation region is different. Further, it is inconvenient for the operator to adjust the light quantity so that the observation site is illuminated with light that can obtain an image of desired brightness every time the processor is used properly.

[0005]

Therefore, in view of the above situation, the present invention can image an observation site by various imaging methods without causing the operator to feel annoyed, and the imaging methods can be switched. It is an object of the present invention to provide a processor for an endoscope device that can continue to observe an image with a desired brightness even in the case of the above.

[0006]

Therefore, the processor for an endoscope apparatus according to a first aspect of the present invention irradiates light from the tip of the scope to obtain an optical image of the observation site formed on the light receiving surface of the image pickup device. It is a processor used in an endoscope apparatus that generates image data. The processor comprises a first light emitting means for emitting a continuous light of a first light amount corresponding to a predetermined brightness of an image, and a strobe light of a second light amount corresponding to a brightness lower by a predetermined amount than the predetermined brightness. Is provided at a predetermined position where the second light emitting means for emitting light, the light emitting instruction means for instructing the second light emitting means to emit strobe light, and the optical path of the light emitted from each light emitting means intersect, Means for guiding only the strobe light to the light guide for a predetermined period during which the strobe light is emitted based on the means, and an optical path switching means for guiding only the continuous light to the light guide except for the predetermined period, and the image data generated by the strobe light. And an image processing unit for making the brightness component correspond to a predetermined brightness.

With the above arrangement, it is possible to provide a processor having a plurality of light sources. Since a plurality of light sources required by the photographer are installed in advance, it is possible to reduce the time and effort required for preparation at the time of imaging, and a single processor can capture and observe a moving image and a freeze image.

According to the above construction, the moving image is picked up by the continuous light which is dimmed so as to have the light amount corresponding to the predetermined brightness when the light is emitted, and the freeze image is the strobe light which is dimmed when the light is emitted. Both images can be observed with a predetermined brightness by being imaged by and adjusted in brightness during image processing.

Further, according to the above configuration, the strobe light is set to be slightly dark at the time of light emission and has a predetermined brightness at the time of image processing. In general, during normal imaging, auto-dimming is set to a relatively bright level so that the deep inside of the body cavity can be observed. Therefore, halation is likely to occur immediately after switching to freeze imaging. In addition, the strobe light source used during freeze imaging was not always good in stability of emission intensity, and thus halation was likely to occur. By carrying out the present invention having the above structure, these halations can be effectively prevented.

According to the endoscope apparatus processor of the second aspect, the first light emitting means includes a first light source for emitting continuous light and a first light amount adjusting means for adjusting the light quantity of the continuous light. And first control means for driving and controlling the first light amount adjusting means so that the potential difference between the luminance signal corresponding to the brightness of the captured image and the reference signal corresponding to the predetermined brightness becomes zero. It is desirable to have By actually comparing the brightness of the captured image with a predetermined brightness, more accurate light amount control becomes possible.

According to a third aspect of the present invention, the second light emitting means includes a second light source for emitting strobe light and a second light quantity for adjusting the light quantity of the strobe light. It is desirable to have adjustment means.

According to the endoscope apparatus processor of the present invention, the image processing means compares the predetermined brightness with the brightness component of the image data, and based on the comparison result of the comparison means. Signal amplification means for amplifying a signal relating to image data. With such a configuration, it is possible to obtain a predetermined brightness even for a freeze image captured by strobe light that is slightly darkened to avoid halation.

According to another aspect of the processor for an endoscope apparatus of the present invention, the first light quantity adjusting means has a first diaphragm arranged in front of the first light source, and the second light quantity adjusting means. The means is
It may have a second diaphragm arranged in front of the second light source.

According to the sixth aspect of the invention, the second light emitting means changes the light quantity of the strobe light to the second light quantity in response to the drive control of the first light quantity adjusting means by the first control means. It is characterized by having a second control means for driving and controlling the second light amount adjusting means.

More specifically, the second control means includes a first opening degree detecting section for detecting the opening degree of the first throttle and a second opening degree for detecting the opening degree of the second throttle. It is preferable that the drive control of the second control means includes a detection unit, and performs closed-loop control based on the detection result of the first opening degree detection unit and the detection result of the second opening degree detection unit ( Claim 7).

In the processor for an endoscope apparatus according to the eighth aspect, the first light amount adjusting means and the second light amount adjusting means are mechanically formed integrally, and in response to the driving of the first light amount adjusting means. The second light quantity adjusting means is also driven.
As described above, by mechanically interlocking and controlling the driving of the two light amount adjusting means, it is possible to achieve the object of the present invention in which images of different types are picked up and observed at a predetermined brightness.

Here, it is desirable that the drive amounts of the first light amount adjusting means and the second light amount adjusting means are determined based on the light emission characteristics of the first light source and the second light source. .

A processor for an endoscope apparatus according to a tenth aspect of the present invention is characterized by further comprising brightness setting means for setting a predetermined brightness. As a result, it is possible to provide a processor capable of controlling the light amount with lightness corresponding to the needs of the operator.

1 is a schematic configuration diagram of an endoscope apparatus 100 according to an embodiment of the present invention. The endoscopic device 100 is
It is composed of a processor 100a and an electronic scope 100b. The processor 100a includes a light source unit 10, a main control unit 20, an image signal processing circuit 30, and an operation panel 40. The light source unit 10 includes a normal light source 1, a flash light source 2, a first diaphragm 3, a first motor 3a, a first driver 3b, a first opening detection sensor 4, a second diaphragm 5, a second motor 5a, and a second driver 5b. The second opening detection sensor 6, the mirror 7, the third motor 7a, the third driver 7b, and the condenser lens 8.
The image signal processing circuit 30 includes a first-stage processing unit 30a and a memory 3
0b and the post-stage processing unit 30c. Electronic scope 100
b has a light guide 50 and its tip 50a, a color CCD 60, and operation buttons 70.

When the endoscope apparatus 100 is used, the observation site is imaged as follows. The normal light source 1 is a light source that can emit continuous light, and for example, a xenon light source or the like is used. The strobe light source 2 is a high-luminance light source capable of emitting strobe light for a predetermined time. Endoscopic device 100
Uses continuous light that is normally emitted from the light source 1 when capturing the observed region as a moving image, and uses strobe light emitted from the strobe light source 2 when capturing and recording the observed region as a freeze image. To do.

If the operator does not perform a specific operation, the endoscope apparatus 100 normally takes an image. At the time of normal imaging, first, the main controller 20 causes the third driver 7 to guide only the continuous light emitted from the normal light source 1 to the light guide 50.
The third motor 7a is driven via b to retract the mirror 7 from the optical paths of continuous light and strobe light. The mirror 7 in the retracted state is shown by a broken line in FIG. Then, the main controller 20 causes the normal light source 1 to emit continuous light. In this embodiment, the normal light source 1, the condenser lens 8, and the light guide 50 are included.
Since and are arranged substantially on the same line, continuous light emitted from the light source unit 10 is guided through the light guide 50 through the condenser lens 8 and is emitted from the emission end 50a on the front end side of the electronic scope 100b. It is irradiated toward the observation site.

When in a light emitting state, the CCD 60 provided at the tip of the CCD receives the light reflected by the observation site and accumulates electric charges corresponding to the optical image formed on the light receiving surface. Then, the CCD 60 outputs the accumulated charge as a voltage value (image signal) to the image signal processing circuit 30. The image signal processing circuit 30 first performs filter processing, A / D conversion processing, and the like on the input image signal in the first-stage processing unit 30a, and then writes it as image data in the image memory 30b corresponding to RGB at the time of image capturing. . Then, the RGB image data is read out at a predetermined timing, and the post-stage processing unit 3
At 0c, D / A conversion processing is performed. The image data processed by the post-processing unit 30c is output to a monitor (not shown) as RGB video signals. The monitor displays a color image of the observation site corresponding to the input video signal. On the monitor, the display image is updated every time new image data is written in the memory, so that the observation site can be observed as a moving image.

When the operator depresses the operation button 70 of the electronic scope 100b at an arbitrary timing, the main control section 20 switches the normal imaging to the freeze imaging at the timing of the depression. At the time of freeze imaging, the main control unit 20 is set so that only the strobe light illuminates the observation site.
The strobe light is transmitted through the condenser lens 8 to the light guide 5
While being guided to 0, the mirror 7 is moved to a predetermined position where continuous light is blocked. The predetermined position in this embodiment is a position where the optical paths of continuous light and strobe light intersect, as indicated by the solid line in FIG. During other freeze imaging,
The display image on the monitor is not updated until the freeze imaging is canceled by the operator again pressing the operation button 70 or the like, that is, the specific state of the observation site is continuously observed as a color freeze image, or the freeze is performed. The difference is that an image can be recorded on a recording medium. However, since the imaging operation other than the above points during freeze imaging is substantially the same as the imaging operation during normal imaging,
Detailed description here is omitted.

The processor 1 which is a feature of the present invention will be described below.
The light emission and the light amount control in 00a will be described in detail.
FIG. 2 is a block diagram relating to light emission control of the processor 100a. FIG. 3 is a block diagram of the post-stage processing unit 30c of the image signal processing circuit 30.

The operator sets the brightness of the image to be picked up via the operation panel 40. The operation panel 40 outputs a signal related to the set predetermined brightness (hereinafter, referred to as a brightness reference signal) to the first comparator 21 of the main control unit 20.

In the normal photographing, as described above, the normal light source 1 is used.
Imaging is performed by illuminating the observation site with continuous light emitted from the. Then, the first-stage processing unit 3 of the image signal processing circuit 30 that receives the image signal output from the CCD 60
0a generates a luminance signal by extracting only the brightness component from the image signal. The brightness signal is output from the first-stage processing unit 30a to the first comparator 21 in the main control unit 20.
The first comparator 21 includes a brightness reference signal and the first stage processing unit 3
The luminance signal from 0a is compared, and the potential difference Ve of the two signals is compared.
1 is applied to the first driver 3b. First driver 3b
Applies the potential difference Ve1 to the first diaphragm 3 via the first motor 3a.
Drive only the amount corresponding to. Continuous light has a potential difference Ve1
The observation site is illuminated by passing through the first diaphragm 3 that has been driven to an opening that reflects. That is, the luminance signal generated based on the image signal changes at any time. In this way, the main control unit 20 controls the light amount of continuous light by driving the first diaphragm 3 so that there is no potential difference between the brightness reference signal and the luminance signal during normal imaging. When the potential difference between the brightness reference signal and the brightness signal disappears, the moving image observed on the monitor has a predetermined brightness.

Generally, the light emitting characteristics of the normal light source and the strobe light source are not constant because they vary depending on the specifications and individual differences regarding the light emitted from each light source, the output voltage at the time of mounting, and the like. However, the light emission characteristics of the normal light source 1 and the strobe light source 2 mounted on the processor 100a are such that the light sources 1 and 2 are actually caused to emit light and the apertures 3 and 5 are turned on in the initial setting performed at the time of manufacturing. It can be found by measuring the amount of light passing through. If the emission characteristics of each light source are known, the apertures of the respective diaphragms 3 and 5 required to obtain the amount of light corresponding to a predetermined brightness can be determined. As described above, the opening of the first diaphragm 3 can be made to correspond to a predetermined brightness by comparing the brightness reference signal and the brightness signal. Therefore,
When the opening degree of the first diaphragm 3 in the state corresponding to the predetermined brightness is detected, the second diaphragm 5 of the strobe light source 2 is adjusted to the opening degree corresponding to the predetermined brightness according to the opening degree. It will be possible.

Therefore, in this embodiment, as shown in FIG. 2, the first opening detection sensor 4 detects the opening of the first diaphragm 3. Specifically, the first opening degree detection sensor 4 detects how much the first diaphragm 3 is opened from the light blocking state (opening degree 0). Then, a signal related to the opening detected by the first opening detection sensor 4 (hereinafter referred to as a first opening signal) is output to the main control unit 20. Main control unit 2
Within 0, the first opening signal is input to the second comparator 25 after unnecessary noise components are removed by the filter 22.

The second diaphragm 5 is driven by the second driver 5b and the second motor 5a. The opening degree of the second aperture stop 5 is detected by the second opening degree detection sensor 6. The second opening degree detection sensor 6 transmits a signal regarding the detected opening degree (hereinafter, referred to as a second opening degree signal) to the amplifier 24 via the filter 23.

The amplifier 24 receives the second opening signal,
The second comparator 25 amplifies the signal with a predetermined amplification factor so that the second comparator 25 has a level comparable to the first opening signal. The predetermined amplification factor is calculated based on the light emission characteristics of the normal light source 1 and the strobe light source 2, which are obtained by measuring the amount of light at the time of initial setting. However, the strobe light source 2 has a higher brightness than the normal light source 1, and has a feature that it can emit strobe light for a short time. Therefore, when the observation area is irradiated with the strobe light, the amount of light that momentarily enters the CCD 60 becomes excessive, and CC
The charge stored in D60 may be saturated. A phenomenon (halation) in which a part or the whole is white may occur in an image captured in a state where the accumulated charges are saturated. Therefore, in the present embodiment, in order to prevent halation, the predetermined amplification factor is not a value as it is calculated based on the light emission characteristics, but is a value corrected so as to be a predetermined amount darker than an image captured by continuous light. Is set to. That is,
The predetermined amplification factor is set such that the light quantity of the strobe light passing through the second diaphragm 5 is slightly smaller than the light quantity of the continuous light passing through the first diaphragm 3 (so that the strobe light becomes slightly dark). . For example, the amount of strobe light passing through the second diaphragm 5 is set to 70% to 95% of the amount of continuous light passing through the first diaphragm 3.

The second comparator 25 compares the first opening signal sent from the first opening sensor 4 with the second opening signal sent from the amplifier 24 to determine the potential difference Ve2 between the two signals. It is applied to the second driver 5b. As described above, the second driver 5b drives the second diaphragm 5 via the second motor 5a by an amount corresponding to the potential difference Ve2. Thus, during normal imaging, the main control unit 2 controls not only the control of the first diaphragm 3 but also the first control so that the potential difference between the first opening signal and the second light amount signal, which have been subjected to the predetermined processing, becomes zero. Closed loop control for driving the second diaphragm 5 is also performed.

However, as described above, the strobe light from the strobe light source 2 is output by the amplifier 24 of the main controller 20.
Since the light amount is controlled to be slightly darker than the predetermined brightness, the freeze image displayed on the monitor remains darker than the predetermined brightness if the closed loop control is kept as it is. Therefore, in the image signal processing circuit 30, a process of correcting the brightness of the image captured by the strobe light is performed.

As shown in FIG. 3, the post-stage processing section 30c is
Each image data of RGB is read out as an image signal from the image memory 30b and converted into an analog signal by the D / A converter 31. The image data that has been converted to analog is VCA (Voltag
It is output to the monitor via the e Controlled Amplifier) 32 and the buffer 33.

The RGB image signals output from the VCA 32 are sent to the matrix circuit 34 and the averaging circuit 35.
In this order, only the luminance signal regarding the captured image is extracted. The luminance signal extracted by each of the circuits 34 and 35 is transmitted to the third comparator 36. Third comparator 36
Compares the brightness reference signal with the luminance signal from the averaging circuit 35 and applies the potential difference Ve3 to the VCA32. VC
A32 amplifies each of the RGB image signals so that the potential difference Ve3 becomes zero.

At the time of normal image pickup, the continuous light is already emitted from the normal light source 1 by the light emission control of the main controller 20 by the light amount corresponding to the predetermined brightness.
3 is almost 0, and the signal amplification processing by the VCA 32 is not performed. However, immediately after pressing the operation button 70 (switching freeze imaging), the image signal captured by the strobe light having a light amount slightly smaller than the light amount corresponding to the predetermined brightness is transmitted to the matrix circuit 36 and the averaging circuit 37. Therefore, the potential difference Ve3 is generated in the third comparator 36. Therefore, the image signal immediately after the start of freeze imaging is V
The signal is amplified by the CA 32, amplified to a level corresponding to a predetermined brightness, and then output to the monitor. In this way, during freeze imaging, the brightness control of the image is performed twice, that is, during light emission and during image processing, so it is possible to obtain a frozen image with a predetermined brightness while preventing halation.

By using the processor 100a as described above, an image having a predetermined brightness can be displayed on the monitor by either of the image pickup methods. That is, both a moving image captured using continuous light and a freeze image captured using strobe light can be observed at a predetermined brightness.

It should be noted that the operator can change the predetermined brightness as necessary by operating the operation panel 40. When the operator changes the brightness, the brightness reference signal changes, so that the main controller 20 and the image signal processing circuit 30 perform the light amount control corresponding to the changed brightness reference signal.

The above is the embodiment of the present invention. The present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention.

In the above-described embodiment, the light amount is controlled by the electric control system to capture the image of the predetermined brightness. However, the light amount of the light emitted from the light source unit 10 corresponds to the predetermined brightness. The control system is not limited to an electric control system as long as it can be controlled.

At the time of initial setting, the size is configured to correspond to the light emission characteristics of the light sources 1 and 2 obtained based on the measurement result of the light amount.
