Problems solved by technology

[0004] However, according to the endoscope with the optical system disclosed in Japanese Patent Application Laid-Open No. 2008-309860, by adopting the above-mentioned display method, the display size of the image in each viewing direction has to be made larger than that of the conventional direct-view endoscope. Mirror or side-view endoscope is small in size, so, as a result, there is a problem of displaying an image with poor visibility

no. 1 Embodiment

[0029] Such as figure 1 As shown, the endoscope system 1 includes: an endoscope 2 for imaging an object to be observed and outputting an imaging signal; a light source device 31 for supplying illumination light for illuminating the object to be observed; A video processor 32 for a video signal corresponding to the signal, and a monitor 35 for displaying an observation image corresponding to the video signal.

[0030] The endoscope 2 is configured to have: an operation part 3 for the operator to hold and operate; an elongated insertion part 4 formed on the front end side of the operation part 3 and inserted into a body cavity; Universal cord 5 extending from the side of part 3.

[0031] The insertion part 4 is configured to have: a hard front end part 6 provided on the front end side, a freely bendable bending part 7 provided at the rear end of the front end part 6, and an elongated flexible part provided at the rear end of the bending part 7. Sexual flexible tube part 8. Fu...

no. 2 Embodiment

[0077] Next, a second embodiment of the present invention will be described.

[0078] In addition, in the following description, a detailed description of parts having the same configuration as that of the first embodiment will be omitted. Moreover, the endoscope system of the present embodiment respectively follows the Figure 1 ~ Figure 3 The appearance structure shown and the Figure 4 The display shown, on the other hand, has the same Figure 5 The structure of the main parts shown is partially different from the structural elements. Therefore, in this embodiment, the main description and Figure 5 The different parts of the structure of the main part are shown.

[0079] First, in Figure 9 In the endoscope system 101 showing the main parts, each part of the imaging element 51, the light source device 31, the video processor 132, and the monitor 35 provided on the front end portion 6 of the endoscope 102 is activated, whereby the image pickup element 51 outputs an im...

no. 3 Embodiment

[0099] Next, a third embodiment of the present invention will be described.

[0100] In addition, in the following description, a detailed description of parts having the same configuration as those of the first embodiment or the second embodiment will be omitted. Moreover, the endoscope system of the present embodiment respectively follows the Figure 1 ~ Figure 3 The appearance structure shown and the Figure 4 The display shown, on the other hand, has the same Figure 5 The structure of the main parts shown is partially different from the structural elements. Therefore, in this embodiment, the main description and Figure 5 The different parts of the structure of the main part are shown.

[0101] First, in Figure 11 In the endoscope system 201 showing the main parts, each part of the imaging element 51, the light source device 31, the video processor 232, and the monitor 35 provided on the front end portion 6 of the endoscope 2 is activated, whereby the image pickup e...

Abstract

Provided is an endoscope system comprising: an endoscope which acquires a direct view image and a side view image of an object to be observed; a detection unit which acquires a predetermined detection result on the basis of a predetermined output signal or predetermined output information; and an image processing unit which performs processing for generating an observation image provided with the direct view image and the side view image within the same screen, enlarging and displaying either one of the direct view image or the side view image in a display unit on the basis of the predetermined detection result, and changing the display form of the other view image in the display unit.

Description

technical field [0001] The present invention relates to an endoscope system, in particular to an endoscope system capable of simultaneously observing a direct-looking direction and a side-looking direction. Background technique [0002] In the medical field, industrial field, etc., an endoscope system that includes an endoscope that images an object inside the subject and that generates an image obtained by imaging the endoscope is widely used in the medical field and the industrial field. An image processing device and the like of the observed image of the subject. [0003] For example, Japanese Unexamined Patent Publication No. 2008-309860 discloses an optical system capable of simultaneously obtaining an object image in a direct-looking direction corresponding to the direction of the central axis and an endoscope having the same. An omnidirectional subject image in a side view direction in which the central axis direction is substantially perpendicular. Moreover, accord...
