[Detailed Description of the Invention] The present invention relates to an image signal processing device for an endoscope device, and includes:
In particular, the present invention relates to a device for processing image signals from a video camera that uses a charge-coupled device attached to an endoscope eyepiece of an endoscope device.

Imaging devices using charge-coupled devices are known. In the present invention, such an imaging device will be referred to as a CCI (video camera). If a CCD video camera is attached to the eyepiece of an endoscope, optical information detected at the end of the endoscope, for example, inside the human body, can be extracted at high speed as an image signal. For example, by inserting an endoscope insertion section into the inside of the ceramic, it is possible to continuously extract the movement at one point inside the helmet as multiple unit image signals in time series.
It is also possible to successively extract a plurality of unit image signals corresponding to a plurality of different points inside the stomach. In this case, it is particularly desired to observe a plurality of unit image signals as one image, or to enlarge and observe a predetermined portion of the i images. Conventionally, as an observation means similar to such a □ observation means, a method is known in which an image from a camera head is projected onto a monitor television device for observation, but this method is inconvenient for making a satisfactory diagnosis. The purpose of the present invention is to convert a plurality of unit image signals obtained from a CCU video camera into one solid solid image signal, and to observe the image formed by this solid solid image signal as one unit. An object of the present invention is to provide an image signal processing device that can enlarge and observe a part of the image.

An image signal processing device for an endoscope device according to the present invention is attached to an endoscope eyepiece section of an endoscope device, and processes an image signal from a video camera using a charge-coupled device. A signal processing device comprising: a camera control unit coupled to the camera; a memory unit for storing a plurality of unit image signals obtained via the camera control unit; and a memory unit coupled to the memory unit. an image signal conversion unit that converts a plurality of unit image signals stored in a pan-fired image signal into a solidified image signal and stores it in the memory unit; and an image signal converting unit that converts a plurality of unit image signals stored in the unit into pan-fired image signals and stores the converted image signals in the memory unit; and a video printer coupled to the memory unit to print image signals from the memory unit.

An embodiment of the invention will be described with reference to the drawings. In the figure, a video camera 3 using a charge coupled device is attached to an endoscope eyepiece 2 of an endoscope 1. Inside the endoscope 1, there is an image guide stand that reaches the endoscope eyepiece 2 and the endoscope tip 4, and a connector part ZAK that reaches the tip 4.
A light guide is provided to reach the area. This endoscope 1
For example, when the light source unit 13 is inserted into the stomach of a human body,
Light is introduced into both images from the tip 4 via the light guide 5. The light receiving section of the video camera 3 receives the light reflected from the stomach wall and passed through the image guide 6, and converts this reflected light into an image signal. Endoscope! Also, illustration of control signals for the video camera 23 is omitted. . This image signal is given to the memory unit 8 via the camera control unit 7. This memory unit 8 is, for example, a desk-type memory; input unit image signals are stored in different areas. Reference numeral 9 denotes an image signal conversion unit coupled to the memory unit 8, which reads out the unit image signal stored in the memory unit 8 in response to a control signal (not shown) and converts the unit image into a unit image by a well-known image reduction process. For example, a plurality of unit image signals are reduced and converted into one solid image signal (an image signal that can display a composite image consisting of an array of images corresponding to the plurality of unit image signals described above on a monitor unit described later), This solid image signal is stored in the memory unit 8. This memory unit 8 also has a monitor 1.
0 is connected. This monitor! , 0 is for reproducing the solid image signal stored in the memory unit 8 as one image, or reproducing the unit image signal stored in the memory unit as an image. A light pen II is coupled to this monitor 10. This light pair 11 specifies which part of the image of the solid solid image signal is desired to be observed, and transmits the corresponding unit image signal to the memory unit 8.
, and reproduces it on the monitor unit 10 as an enlarged image of this portion. Furthermore, a video printer 11 is coupled to the memory unit 8. This video printer prints the unit image signal stored in the memory unit 8 or the above-described solid image signal in response to a control signal (not shown).

Next, the effects of the above embodiment will be explained. Assume that the endoscope I is inserted into the stomach of a human body, for example. Light from a light source unit 13 is introduced into one end of the light guide 5. If this light guide b-id is incident on the light receiving section of the CCD video camera 3 via the light guide 6. Therefore, the video camera 3 also generates a first unit image signal related to the vicinity of one end of the light guide 5. This first unit image signal is stored in a corresponding area of the memory unit 8 via the camera control unit 7. The image corresponding to this first unit image signal can be viewed by means of a monitor unit or this unit image signal can be printed by a video printer II. Next, if the position of the endoscope tip 4 is changed and a second point in the stomach is irradiated with light from the light guide 5, a second unit image signal near this second point will be generated in the same manner as above. You can also get 3 video cameras. This second unit image signal is stored via the camera control unit 7 in a location different from the storage location of the first unit image signal in the memory unit 8. Do the same for the 3rd and 4th points on the back.
... are stored in different storage areas of the memory unit 8. The image signal conversion unit 9 converts the first and second unit image signals related to the vicinity of the first point, second point, etc. in the stomach, respectively, into a well-known solid solidified image signal, and A cell that stores the fixed image signal in a corresponding storage area of the memory unit 8.

The monitor unit 10 is a memo IJ unit 8.
It is possible to monitor not only the image corresponding to the unit image signal stored in , but also the image corresponding to the solid image signal. In this case, light pen 1
When a desired portion of the image on the monitor is specified by 1, the unit image signal corresponding to the specified portion is read out from the memory unit and reproduced on the monitor unit 10 as an enlarged image. The video printer 11 has the first,
