Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention is a system for an endoscopic chain that can be used by integrating a separate field-sequential processor and a MOIF processor.
Regarding Ij control device. [Prior Art] In recent years, optical endoscopes (also called fiberscopes) have been developed that transmit an optical image formed by an objective lens on the distal end of the 1i11 human part to the proximal side using an image guide formed by a fiber bundle r. Instead, the optical image formed by the objective lens is photoelectrically converted into an electric image by a prisoner imaging device such as a charge-coupled device (hereinafter referred to as COD) and transmitted to the hand side, and the image is transmitted to the hand side. Videobuot equipped with signal processing means? Electronic endoscopes (hereinafter also referred to as electronic endoscopes or electronic scopes) that can be displayed on a color monitor via a tube have become a reality. The above-mentioned electronic scope is currently used for the upper or lower gastrointestinal tract after 10φrfI. However, for example, an endoscope for the bronchus usually requires an endoscope with a diameter of 5 mm or less, and in order to realize an electronic scope for the bronchus (small diameter), it is necessary to use an image sensor with a small number of pixels. One colander! ? do not have. When the number of pixels mentioned above is small, rather than using a color image method that uses a color mosaic filter to prevent a decrease in resolution, light of each wavelength of red, blue, and green is illuminated in a sequential manner. The IQ is performed sequentially with , and these are combined to display the 14-screen sequential color display! & Statue method is right-handed. On the other hand, the diameter is large, the number of pixels is large, and the resolution is 4 to 7.
In such cases, a seven-saic color image method using a mosaic filter may be adopted. Top 2! In the case of an electronic scope, in addition to the light source device used in a 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 camera and light source device for the electronic scope. For this reason, for example, as disclosed in Japanese Patent Application Laid-Open No. 60-243625 f'', a fiberscope with 11gm
A system was proposed that could display images on both sides of a color monitor by connecting an adapter. In the conventional example above, when an image carrier adapter is connected, it is a frame-sequential color system! It is possible to form an electronic scope that performs 1Ilf&, and when connected to a control device (integrated with a video processor and a light source device), it is possible to perform color display on a frame-sequential image. [Problems to be Solved by the Invention] The above system has a drawback in that a color modifier scope cannot be connected and used. - On the other hand, if a device that can be used with either a field-sequential type or a (color) mosaic type scope is formed in one piece, it is convenient because it can be used with any scope, but the result is larger size and more overlap. Therefore, it can be inconvenient when carrying a mobile phone. In other words, it would be convenient to have a system that can be used as an integrated unit or as separate units depending on the purpose. The present invention has been made in view of the above-mentioned points, and can be integrated and used with any scope, and can also be separated for convenient transportation and used only with the required scope. It is an object of the present invention to provide an endoscope control device that is compatible with the present invention. [Means and effects for solving the problems] The present invention has signal processing means for color 11-image scopes of different systems, and has a mechanism for combining and integrating separate video processors. control (

The Iia section 16b illuminates with white light, and the light from the white lamp 52b is focused by a lens 53b and irradiated onto the connector receiver 13b, and is illuminated by a (light guide) connector connected to the connector receiver 13b. Provides white light. On the other hand, the surface sequential method! 1Jt11 Light source section 1 in device 2a
6a, the light from the white lamp 52a passes through a rotary filter 56 rotated by a motor 55, and then is condensed by a lens 53a to supply illumination light toward the connector receiver 13a. As shown in FIG. 7, the rotary fill ladder 56 has R, G, and B color transmission filters 62r
2G and 82B are design numbers, and for example, a hole 63 for white illumination is located in the dark light-shielding part of the R and B color transmission filters 62R and 62B, and this hole 63 is located at the center of the hole 63. The filter frame 61 is rotated by the motor 55 so that the light can be blocked by the light shielding plate 64. In this state, centrifugal force causes the direction connecting the center position of the disk-shaped light-shielding portion and the pivot point to match in the radial direction, as shown in FIG.
4, the screen is blocked, and normal R, G, and B surface sequential illumination can be performed. On the other hand, when it stops, the centrifugal force does not work, so the light shielding plate 64 retreats from the hole 63 due to gravity, as shown in FIG. The position of the filter frame 61 is controlled such that the hole 63 is located on the optical axis connecting the light source lamp 52a and the lens 53a in the stopped state. For this position control or R, G, B

The filter frame 61 has a large number of holes 65, 65, . . . in the circumferential direction.
A light emitting element and an A sensor 66 are arranged on both sides of the plate surface of the filter frame 61 to form a position sensor 67 corresponding to a rotary encoder. In FIG. 7, the photosensor 66 is attached to the tip of a sensor mounting plate 68. The output of this position sensor 67 is input to the timing generator 51a, and this timing generator 51a lights up Jlf! with 8 lights of R, G, and 8! At the end of I, driver 26ak outputs a timing signal for reading. In synchronization with this timing signal, the driver 26a applies a drive signal to the CGD 19 or 22 and reads out the signal. By the way, the field-sequential type scope 2a and the mosaic type υI department r! 12b is designed so that it can be connected and integrated as follows, for example. As shown in FIG. 1, a panel cover 7 that is rotatable with a hinge or the like is provided at the lower front of the field sequential type/partial ff12a.

The panel of the i+Ji11 device 2b can be covered. In this state, the curved surfaces of both control devices 2a and 2b can be fixed using screws 72 (only one of which is shown at 1°). In addition, fixing plates 73a (only one of which is shown) are provided on the lower sides of both sides of the field sequential system ti11 device 2a, and by shifting the fixing plates 73a downward,
By protruding to the lower side, as shown in FIG. 9, it can be engaged with the fixing notch 74b of the lower control device 2b, and the four screws 75.・-, 75 allows both connecting devices ff12a, 2b to be integrally connected F'c from the side. Further, a connecting connector plate 77 as shown in FIG. 10 is attached to a position near the front and lower side of one side of the control device 2a. This connection connector plate 77 has the same shape on the top and bottom, and a pair of connectors 78° 78 are connected to the flat cable 7.
They are connected to each other via 9. This connector plate 77

A/FI facing, connector number 83 has terminal 48b
, 49b, 50b'/fi, and by connecting the connector plate 77, the opposing terminals in FIG. 2 are brought into conduction. In the state in which both control devices 2a and 2b are integrated as shown in FIG. 9, each switch in the trust processing system shown in FIG. 2 is changed over so that the mosaic type signal processing system is selected. That is, the switch 29a is turned on, the switch 29b is turned on, the contact a1 is turned on, and the switch 35 is turned on. In addition, the operation using the panel 12a is performed using the panel control 81/1.

The signal is transmitted to U47b and sent to the mosaic processing system where the gain and contour enhancement level are controlled. In addition, the light source part 1
6a maintains a stopped state in which the rotating filter 56 does not rotate, that is, a state in which white light is supplied. Further, the CPU 47a is in a state where it cannot receive a signal from the panel lli control unit/16b. By the way, in the above-mentioned integrated state, the field sequential type scope 3
When A or 3C is connected, type signal generation circuit 27Δ
or 27G, the identification circuit 28a identifies the type, and in response to this identification, the field sequential signal processing system is selected and a @ rotation command signal is output to the rotation/stop control circuit 85. The motor 55 is then rotated to provide sequential illumination. . When the identification circuit 28a determines that the field sequential scope is 3Δ or 3C, the switch 298 selects the contact a side, and also outputs a switching signal to the CPU 47a, and switches the switch 35 to the contact a side, that is, as shown in FIG. Both switches 29a and 35 are switched to the state shown in FIG. (The contact a side of the switch 29b remains on.) Incidentally, the frame-sequential process circuit 31a has a configuration shown in FIG. 11, for example. That is, the signal inputted via the preamplifier is inputted to the 1 number hold circuit 87 via the variable gain amplifier 86, sampled and held, then γ corrected by the γ correction circuit 88, and converted into a digital quantity by the Δ/D converter 89. is converted to Thereafter, the signals transmitted under the sequential illumination of R, G, and B through the multiplexer 90, which is switched by the signal from the timing generator 51a, are transferred to the R frame memory 91R, the G frame memory 91G, and the B frame memory 91B. written.

are generated chronologically for each horizontal line, white balance is corrected by a white balance circuit 97, one is sent directly to an analog switch 98, and the other is extended one horizontal line by a 1H delay line 99 to an anno. It is input to the log switch 98' and the timing generator 5
Color difference signals RY and [3-Y are obtained by the switching signal 1b. According to the first embodiment configured in this way, when both the control devices 2a and 2b are in a separate state, each control section vi2a:'2
b can be used exclusively for the field sequential type scope 3Δ, 3C knee-e-seik type scope 3B, and 3D. Also, any fiber scope 3 can be used. Therefore, if you know which scope to use, or if you only have one Wi-Li type scope, you can use only the necessary control device without moving the other control device. On the other hand, if you need to use a scope with a different image carrier method, or if you do not know which method the scope uses, you can use either scope by combining the two names, so it depends on the purpose of use. be able to respond appropriately.
