2. Description of the Related Art Conventionally, when outputting an image observed by a microscope, the image being monitored is directly output by a video printer or, as shown in FIG.
A / D the video signal after video signal processing of the CD output
The converted video signal is converted and recorded in the memory 9 or the like, and then the D / A converted and reproduced video signal is output by the video printer 17, or the video signal is recorded on a video tape and reproduced as shown in FIG. The produced video signal was output by the video printer 17.

However, the above-mentioned conventional microscope requires a means for recording / reproducing on a memory or a videotape according to the number of recorded sheets, and also requires a video printer, which is a systematic form. Was also large and expensive.

[0005]

SUMMARY OF THE INVENTION The present invention is intended to eliminate the above-mentioned drawbacks of the prior art, and is provided with means for changing the image forming surface of a subject by a mirror or the like and means for photographing on a photographic film. .

[0006]

The function of the microscope constructed as described above operates as follows. If the photographer wants to record the subject while observing the subject, he or she presses a switch or the like so that the subject that had been focused on the CCD until then is focused on the film by means of changing the focusing surface. ,
Shoot on film.

Reference numeral 14 is a film, and 15 is a monitor.

Next, the operation of the microscope constructed as described above will be described with reference to FIGS. 1 and 2. During normal observation of an object, the image of the object passes through the microscope lens 1 and is reflected by the mirror 2 (the position shown by the solid line in FIG. 1) to form an image on the CCD 3. Since the image at this time is reflected by the mirror and is an image which is horizontally inverted, it is necessary to reflect the image again on the mirror 15 and then form the image on the CCD 3 in order to display a normal image on the monitor 15. Therefore, only one mirror is required by using a mirror image output CCD that can output a signal whose right and left are inverted by reversing the transfer direction of the horizontal CCD to the CCD 3.

A subject imaged on the CCD 3 is separated into a luminance signal and a color signal by an image signal processing circuit 4 as an electric signal, and after undergoing processing such as clamping and gamma correction, a luminance signal Y and a color difference signal R-. Y and color difference signals BY are separated. These signals are supplied to the encoder 6 through the switch 5 and are given to the monitor 15 as video signals so that the subject is displayed on the monitor 15. On the other hand, the luminance signal Y, the color difference signal RY, and the color difference signal BY are converted into digital data by the A / D converter 8 and are sequentially stored in the memory 9 for each frame.

When the observer wants to record the subject, he or she pushes the switch to move the mirror 2 which has reflected the image of the subject to the CCD 3 to the position shown by the broken line in FIG. 1
In 2, the subject is imaged on the film 14, and the shutter 13 is opened for a certain period of time to photograph the subject on the film 14. A photograph is obtained by developing the film 14.

No image is input to the CCD 3 at the time of taking a picture, so that the subject is not displayed on the monitor 15. At this time, the data immediately before shooting stored in the memory 9 is converted by the D / A converter 10 into a luminance signal Y and a color difference signal RY,
The color difference signal BY is reproduced, supplied to the encoder 6 through the switch 5, and given to the monitor 15 as a video signal, and a still image of the subject immediately before shooting is displayed on the monitor.

The microcomputer 11 performs A / D conversion and write operation to the memory 9, read data from the memory 9 and D / A conversion, and controls the switch 5.

[0013]

Since the microscope of the present invention is constructed as described above, the invention according to claim 1 does not require a large amount of memory or means for recording / reproducing on a video tape, and also requires a video printer. Therefore, downsizing and cost reduction can be realized as a system. However, the invention according to claim 2 can prevent the image on the monitor output from being interrupted even when taking a picture, thereby eliminating an unnatural feeling. In addition, the invention described in claim 3 minimizes the number of mirrors that change the image plane, and obtains an image that is not horizontally inverted.
