Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a magnifying observation apparatus suitable for easily magnifying and observing various observation objects in various fields such as beauty, medicine, academics, and industry.

[0002]

[Prior Art]

 The present applicant has previously proposed Japanese Patent Application No. 2-224327 regarding a magnifying observation apparatus. This Japanese Patent Application No. 2-224327 is intended to simplify a magnifying observation apparatus as disclosed in, for example, Japanese Patent Application Laid-Open No. 1-308527, and uses an optical fiber used in Japanese Patent Application Laid-Open No. 1-308527. Instead of the external light source for illumination, the imaging tool incorporates a light source for illumination of the observation object, that is, a lamp for simplification.

By the way, one of the important things in these magnifying observation devices is to make the depth of focus larger, and for this reason, because of the relationship of reducing the diaphragm, the illumination source of the observation object is more powerful. That is, to be able to give something like that. Therefore, in the case of the built-in illumination lamp type, a more powerful lamp is used, but there is a problem that the inside of the imaging tool becomes hot due to the heat generated by the powerful lamp.

[0004]

[Problems to be solved by the device]

 Therefore, the present invention has an object of a magnifying observation apparatus equipped with an imaging tool having a built-in illumination lamp so as to avoid unnecessary lighting of the illumination lamp and to suppress heat generation.

[0005]

[Means for Solving the Problems]

 For this purpose, in the present invention, the case body is provided with an imaging means for capturing an image of the observation object formed by the optical system and an illumination lamp for illuminating the observation site of the observation object. To the storage means, the magnifying observation apparatus including the image pickup tool, the display for reproducing the image of the observation object picked up by the image pickup means, and the storage means for storing the video signal from the image pickup means and outputting it to the display are displayed. The video signal input control and the lighting lamp ON / OFF control are interlocked with each other so that the lighting lamp is turned off when the input of the video signal to the storage means is stopped.

In this magnifying observation apparatus, the video signal obtained by the image pickup means is temporarily stored in the storage means, and then output from the storage means to the display. This is to enable the observation of a specific part of the observation object as a still image when observing the specific part intensively. In other words, when an observer scans the imaging tool and observes a part that requires detailed observation, he / she intensively observes that part, but the images obtained by scanning, that is, through images In the case of observation with (moving image), a new image is always output to the display while being stored in the storage means, and in the case of intensive observation, the acquisition of the image in the storage means is stopped, and Only the image of the relevant part stored is output as a still image on the display.

In the case of such observation with a still image, it is not necessary to take in a new image, and therefore illumination with an illumination lamp is also unnecessary. Therefore, in the case of still image observation, that is, when the input of the video signal to the storage means is stopped, the illumination lamp is turned off in conjunction with this, and this is used for illumination. It is possible to avoid unnecessary lighting of the lamp.

The interlocking structure of the input control of the video signal and the ON / OFF control of the illumination lamp is preferably such that the case body of the imaging tool is provided with an automatic resetting type push button switch. While the button is pressed, the video signal can be input to the storage means and the illumination lamp is turned on, while when the push button switch is opened, the input of the video signal to the storage means is stopped. In addition, the illumination lamp is turned off.

【Example】

 An embodiment of this invention will be described below. As shown in FIG. 2, the magnifying observation apparatus 1 according to this embodiment includes an imaging tool 2, a control unit 3, and a display 4.

As shown in FIG. 3, the imaging tool 2 includes an optical system 5 for forming an image of the observation object M at a predetermined magnification, an imaging means 6 for capturing the image of the observation object formed by the optical system 5, Also, an illuminating lamp 7 for illuminating the observation site of the observation object M is built in the case body 8, and the imaging means 6 is a solid-state camera using a solid-state imaging device such as CCD. ing. In the figure, 20 is a lens, 21 is a filter unit for an optical system, 22 is an optical path changing mirror, 23 is a diaphragm, and 24 is a filter unit for an illumination system.

As shown in FIG. 1, the control unit 3 is provided with a storage means 9 for storing a video signal from the image pickup means 6 and outputting the video signal to the display 4, and the image signal stored in the storage means 9 is stored in the storage means 9. A switching control circuit 10 is provided for interlocking ON / OFF control of the illumination lamp 7 of the imaging tool 2 with input control. On the other hand, the image pickup tool 2 is provided with an automatic resetting push button switch 11 so as to project to the surface of the case body 8, and this push button switch 11 is connected to the switching control circuit 10. .

To use such a magnifying observation apparatus 1, the imaging tool 2 is held in the hand, and the push button switch 11 is first depressed. Then, the illumination lamp 7 is turned on through the switching control circuit 10 and the video signal output from the image pickup means 6 can be taken into the storage means 9. In this state, while illuminating the observation site of the observation object M 1 by the illumination lamp 7, the image is captured by the image pickup means 6 and output to the display 4 for observation.

[0013] Such an observation is a through image (moving image) observation in which new images are successively captured and reproduced. However, during the through image observation, particularly detailed observation is required. If you encounter a part you need, make a through image still image and observe. This still image observation is performed in a state in which the acquisition of a new image in the storage means 9 is stopped, and is performed by reproducing the video signal stored in the storage means 9 on the display 4 before the stop. At this time, the stop of capturing the image in the storage means 9 is performed through the switching control circuit 10 by releasing the depression of the push button switch 11, and at the same time, the illumination lamp 7 is also turned off. The timing relationship for the above operations is shown in FIG.

[0014]

[Effect of the device]

 As described above, the magnifying observation apparatus according to the present invention is designed such that the video signal from the image pickup means is temporarily stored in the storage means and output to the display, and the video signal is input to the storage means. Since the control and the ON / OFF control of the illumination lamp are linked, it is possible to reliably prevent unnecessary lighting of the illumination lamp in the case of observing a still image. Therefore, in such a magnifying observation apparatus, a stronger illumination lamp can be adopted, and a larger depth of focus can be achieved, so that better observation conditions can be realized.
