DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ophthalmologic photographing apparatus used in mass examinations and ophthalmic clinics.

[0002]

2. Description of the Related Art Conventionally, in an ophthalmologic photographing apparatus such as a fundus camera, supplementary information such as the name of an eye to be examined, a photographing date, and a time is input by an operator of the ophthalmologic photographing apparatus using an input device such as a keyboard. The information is recorded together with the fundus image.

[0003]

However, in the above-mentioned conventional example, the information input operation is complicated and time-consuming, so that the operator of the ophthalmologic photographing apparatus can accurately input a fundus image or the like by an input device such as a keyboard. It may be difficult to input and record textual supplementary information such as the name of the subject's eye, the shooting date, and the time.

In addition, the name of the eye to be examined,
In some cases, character accompanying information such as a shooting date and a time is not always accurately associated with a fundus image or the like due to an operation error or the like.

An object of the present invention is to solve the above-mentioned problems,
It is an object of the present invention to provide an ophthalmologic photographing apparatus that incorporates and records image information for accurately identifying an eye to be examined, together with a fundus image of the eye to be examined and character accompanying information.

[0006]

An ophthalmologic photographing apparatus according to the present invention for achieving the above object has an illumination optical system for illuminating an eye to be inspected, and an imaging optical system for photographing the eye to be illuminated by the illumination optical system. System, image input means, additional information input means, and image management means for filing the image information obtained by the image input means and the additional information obtained by the additional information input means. I do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the illustrated embodiment. FIG. 1 is a configuration diagram of an ophthalmologic photographing apparatus according to the present embodiment. A horizontally movable movable base 2 is mounted on a base 1, and a removable recording medium such as a magneto-optical disk, a magnetic disk, or an IC card is recorded on a lower surface of the base 1 on the examiner side. A recording / reproducing unit 3 for reproducing is attached. Further, a keyboard 4 on which the examiner performs an input operation is connected to the base 1 via a cable.

Also, on the movable base 2, a main body section 5 having a built-in optical system, a forehead rest and a chin rest 6 on which the face of the examinee's eye is placed, and a CRT or liquid crystal display for displaying the examinee's eye for alignment A display means 7 including a face, a face photographing unit 8 for photographing the face of the eye to be examined, and a fingerprint reading unit 9 for reading a fingerprint are mounted.

FIG. 2 shows an electric block circuit diagram.
The base 1 has a built-in MPU (microprocessing unit) 11 for controlling the entire apparatus.
U11 has a ROM storing a control program and the like.
(Read only memory) 12, R for temporarily storing data
AM (random access memory) 13, image management means 1
4. The recording / reproducing section 3 of the recording medium and the display means 7 are connected. Further, the MPU 11 has an image input means 15 composed of a CCD camera or the like.
Additional information input means 16 for inputting patient information such as D number, angle of view, distinction between left and right eyes, and a timer value obtained by a counting circuit during fluorescent imaging, keyboard 4, face photographing section 8, fingerprint reading section 9 is connected.

FIG. 3 shows a display screen of the display means 7. The display means 7 displays a fundus image 21, a face photograph image 22, a fingerprint image 23, and character accompanying information 24 of the examinee's eye. The character supplementary information 24 includes, for example, the image name 25, the ID number 26, the examinee's name 27, the date of birth 2
8, a shooting date and time 29 and an angle of view 30 are displayed.

In the ophthalmologic photographing apparatus having such a configuration,
When the face of the examinee's eye is fixed to the forehead rest and the chin rest 6 and a xenon tube (not shown) emits light, a fundus image of the examinee's eye is formed on the image input means 15 in the main body 5 and then converted into an electric signal. The data is temporarily stored in the RAM 13 via A / D conversion. At this time, the character management information of the examinee's eye input through the additional information input means 16, the keyboard 4, and the recording / reproducing unit 3 of the recording medium is also stored in the RAM 13 together with the fundus image by the image management means 14 and then recorded. The information is recorded on the recording medium by the reproducing unit 3.

Similarly, the input image taken by the face photographing section 8 is converted into an electric signal after being formed on the image input means 15 and once stored in the RAM 13 via A / D conversion. The recording / reproducing unit 3 records the data on a recording medium. The input image read from the fingerprint reading unit 9 is
The image is converted into an electric signal in the fingerprint reading unit 9, converted into a digital image via A / D conversion, temporarily stored in the RAM 13, and then recorded on a recording medium.

In this manner, the photographer sequentially photographs the fundus images of the subject's eye, and sequentially records the images on the recording medium by the recording / reproducing unit 3. After the photographing of the fundus image is completed, the screen is switched by a screen changeover switch (not shown), so that the fundus image 21 of the examinee's eye, the face photograph image 22 as the accompanying information, the fingerprint image 23, and the character accompanying information 24 as shown in FIG. It can be displayed on the display means 7.

FIG. 4 shows a link configuration diagram of a data file on a recording medium. A file F1 storing a fundus image group of the eye to be examined, a file F2 storing a face photograph image, and a fingerprint image are stored. File F3, and a file F4 storing character accompanying information such as a name. The files F1 to F4 are linked bidirectionally.

Therefore, even if a link having one direction is disconnected, the connection relationship originally possessed can be restored by following the remaining three links.

FIG. 5 shows a file structure diagram of a recording medium according to another embodiment. Between data D1 storing a fundus image of the eye to be inspected, data D2 storing a photograph of the face of the eye to be inspected, and data D storing a fingerprint image
3. Linkage is made between data groups of supplementary information composed of data D4 storing character supplementary information such as names, and a part or all of the supplementary information stores a fundus image of the subject's eye. It is stored as a single file F5 in addition to the data D1.

Therefore, since there is no link information indicating the relationship between the fundus image data D1 of the eye to be examined and the data D2 to D4 storing various accompanying information data, there is no such information.
A situation in which the data D1 to D4 dissipates does not occur.

[0018]

As described above, the ophthalmologic photographing apparatus according to the present invention can record the recording of an image file and the like with a plurality of supplementary information, especially the face photograph of the eye to be examined, in association with the image. Further, if the fingerprint image is recorded in association with the fingerprint image, the examinee's eye can be easily identified. In addition, the number of erroneous operations by the operator is reduced, and even in the case of erroneous operations, the configuration is easily visually corrected, so that important data of the examinee can be protected.
