Abstract

PURPOSE:To pick up an image in two directions at the same time by one scope by projecting light images which are incident from a front and a sideward view window provided on the tip part of the scope on image pickup surfaces for front and sideward view areas and displaying the two images on a screen. CONSTITUTION:The light image incident from a front view objective lens 11 is projected on the front view image pickup area by a CCD 13 through a mirror 13 and light image incident from a sideward view objective lens 12 is projected on the sideward view image pickup area of a CCD 14 directly. The output signal of the CCD 14 is inputted to a signal processing circuit 3 in a device main body 2 to perform processes such as main component analysis, filtering, and R, G, and B conversion of a video signal, so that front view and sideward video image data are written in the image memory of a DSC 4 while crossing each other. Then a video processor reads the front and sideward view images in orthogonal directions and then while a normal image of both images is displayed on a monitor 5, normal images of the front and sideward view images are displayed on monitors 6 and 7.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) This invention images a subject using a scope with a built-in solid-state imaging device (hereinafter referred to as CCD) at its tip, and The present invention relates to an electronic endoscope device that displays contents on a screen.

(Prior Art) Conventionally, this type of electronic endoscopic I! In order to capture images corresponding to the bent shape and communication state within the body cavity, the device allows scopes to be appropriately selected and used interchangeably.

For example, when imaging the inside of the stomach, a forward-looking scope for the upper gastrointestinal tract and a side-viewing scope are selected and used interchangeably, and when imaging the inside of the large intestine, A forward-looking scope and a side-viewing scope were selected and used interchangeably.

However, such exchange of scopes even when imaging the inside of the same body cavity places a strong operational burden on the doctor and the patient, and also causes a large loss of time.

(Problems to be Solved by the Invention) As described above, in the case of the conventional electronic endoscope 5A, a forward-viewing scope and a side-viewing scope must be prepared in order to image the inside of the vagina of the same body. In addition, when these scopes are exchanged, there are problems such as a burden on the doctor and the patient in terms of operation, and a large amount of time lost.

This invention was made to solve the above-mentioned problems, and its purpose is to enable simultaneous imaging in two directions (forward view, side view) within the same body cavity with one scope. The object of the present invention is to provide an electronic endoscope device.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the electronic endoscope device of the present invention divides the m image plane of the solid-state image sensor into a forward viewing area and a side viewing area. On the other hand, a forward viewing window and a side viewing window are provided at the tip of the scope, and the light image incident from the forward viewing window is projected onto the imaging surface of the forward viewing area, and the light incident from the side viewing window is The system is characterized in that a video signal obtained by projecting an image onto a 1@image plane in a side viewing area is subjected to display processing, and two images, one for forward view and one for side view, are displayed on the screen.

(Function) With the electronic endoscope device having such a configuration, forward view imaging and side view LA images can be achieved with the same scope, so known display processing can be applied to video signals based on these @ images. By applying this, it is possible to simultaneously view screens in two directions within the same body cavity.

Therefore, the conventional problem of having to replace scopes can be solved all at once.

(Embodiment) FIG. 1 is a block diagram showing an outline of an electronic endoscopic #ft device to which the present invention is applied, and FIG. 2 is a configuration diagram showing details of main parts of a scope of the electronic endoscope device.

In this electronic endoscope device, as shown in FIG. 2, the scope 1 includes an objective lens 11 for forward vision and an objective lens 12 for side vision on the outer surface of the distal end portion 1a.
and an objective lens 1 inside this tip 1a.
A light image incident from 1 is transmitted to a CCD 14 via a mirror 13.
(See FIG. 3), and a scope is used that is configured to directly project an optical image incident from the objective lens 12 onto the CCD 14.

As shown in FIG. 1, the device main body 2 to which the scope 1 is attached is provided with red (R), red (R),
A signal processing circuit 3 performs RGB conversion of green (G) and blue (B), and receives the output of the signal processing circuit 2 and inputs image data to an image memory (see Figure 3) and converts images from the image memory. It includes a digital scan converter (DSC) 4 that transfers data to a processor (not shown) and performs processing to enlarge or reduce the image.

In addition, the output from the DSC 2 of the Hat main body 2 is output from the monitor 5.
~6.

Next, the operation of the electronic endoscope apparatus of the present invention shown in FIGS. 1 and 2 will be explained with reference to FIG. 3.

The imaging surface of the CCD 14 is viewed from the front as shown in Figure 3).
1 image area 14a and the side? It is divided into J1 jumping image carrier A 14b. CC
When the reading direction of D14 and the writing direction to the image memory of DSC4 are D in the same figure, the contents written in the image memory of DSC4 become as shown in FIG. Next, if the image memory of the DSC 4 is read out by the video processor of the same DSC 4 in a reading direction in which the forward view screen and the side view screen are perpendicular to each other, as shown in FIG. The read data in the figure (e) is such that both screen data shows the normal image on the screen, so the read data is as shown in the figure (f).
) The output signal from the DSC 4 can be output and displayed on the monitor 5.

In addition, the normal image of the forward view image is displayed on one of the monitors 6 and 7.
The normal image of the side view image can be output and displayed on the other side.

[Effect of the invention] As explained above, the electronic family celebration lI to which the present invention is applied
￥R position is forward view imaging and side view! ! Because it has a simultaneous two-direction MS configuration that simultaneously performs IIF images, it is possible to display forward-view images and side-view images on the display screen of one monitor,
Furthermore, a front view image can be displayed on each of the two monitors' display screens, and a side view image can be displayed on the other screen. Therefore, it will be easy for the surgeon to perform the examination without overlooking any mistakes.
