DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the illustrated embodiment. FIG. 1 shows a configuration diagram of an ophthalmologic photographing apparatus according to the first embodiment. A television camera 3 is attached to a fundus camera 1 such as a fundus camera via a television adapter 2 and further via a television signal cable 4. CPU5
a, a television monitor 5b, a recording unit 5c, and an image recording device 5 composed of an image capture board and the like.

The image recording device 5 is connected to an image capturing mode selection device 7 via a control signal cable 6. Device 9 is connected. The fundus camera 1 and the image recording device 5 are connected via a control signal cable 10.

FIG. 2 shows a television monitor 5b of the image recording apparatus 5.
Shows the patient information input screen displayed on the screen, and the photographer receives the recipient ID number, the name of the patient, the date of birth, the gender, the left and right eyes, etc. Is input to the image recording device 5 from the examinee information input device 9. FIG. 3 shows an example of a patient information input screen displayed on the television monitor 5b after the patient information has been input.

FIG. 4 is a flow chart showing an imaging procedure using the ophthalmologic imaging apparatus according to the present embodiment. First, when the patient information is input, the image recording device 5 is in a state of waiting for a photographing signal. Subsequently, after the photographer performs a precise alignment between the fundus camera 1 and the eye to be inspected, when the photographing switch of the fundus camera 1 is pressed, the output from the fundus camera 1 is output via the control signal cable 10 to the image recording device. The photographing signal is sent to 5, and a light emission permission signal from the image recording device 5 is waited.
When a photographing signal is input from the fundus camera 1, the image recording device 5 synchronizes with the television signal input via the television signal cable 4, and transmits a light emission permission signal to the fundus camera 1 via the control signal cable 10. Send. The fundus camera 1 that has received the light emission permission signal makes the xenon tube emit light in synchronization with the signal to photograph the fundus, and the image recording device 5 captures the illuminated fundus image and displays the image on the television monitor 5b as shown in FIG. Is displayed.

After confirming this screen, the photographer presses the save button with the cursor to save the image when saving. Subsequently, after the image is stored and when the user does not want to store the image, it is determined whether or not the image capturing is completed. When the image capturing is completed, the image recording apparatus 5 selects the end to end the image capturing.

If the photographing is not completed, there is a possibility that the continuous photographing corresponding mode is selected from the image photographing mode selecting device 7, and it is determined whether or not the continuous photographing corresponding mode is set. In the case of the continuous imaging mode in which imaging is continuously performed with the same examinee ID number, the image recording apparatus 5 holds information unique to the examinee, such as the examinee ID number and the examinee name, and continuously waits for an imaging signal. Then, the photographer again performs precise alignment between the fundus camera 1 and the subject's eye and repeatedly presses the photographing switch, whereby continuous photographing becomes possible. This continuous imaging mode is an imaging mode in which a plurality of images of the same examinee are imaged, and is useful for imaging using a mydriatic retinal camera and fluorescence imaging.

Further, in the case of the single image capturing mode instead of the continuous image capturing mode, pressing the new button on the screen with the cursor clears all the patient information and automatically shifts to the patient information input screen. Then, the user is prompted to input the patient information again. Therefore, the photographer can
The procedure is repeated from the input of the examinee ID number. Incorrect examinee ID
It is possible to prevent shooting at a number beforehand. The process from the patient information input screen to shooting and saving is the same as in the continuous shooting mode described above. This single image capturing mode is useful when capturing only one image of the same examinee in a group examination or the like using a non-mydriatic retinal camera.

The continuous shooting mode and the single shooting mode can be selected by an image shooting mode selection device 7, and the photographer can select the image recording device 5 according to the shooting purpose.
Select the image shooting mode.

As a second embodiment, a case will be described in which the fundus camera 1 communicates with the image recording device 5 via the control signal cable 10 in the shooting corresponding mode of the fundus camera 1. In the case of normal color imaging, only one image is taken for one examinee. In the case of fluorescence imaging using a non-mydriatic retinal camera compatible with fluorescence imaging, a plurality of images are taken.

For this reason, when the color photographing corresponding mode signal is input from the fundus camera 1 to the image recording device 5, the image recording device 5 selects the single photographing corresponding mode and the fluorescence photographing corresponding mode is selected. In this case, the continuous imaging mode is selected, and the patient information management mode corresponding to the imaging mode is automatically selected. The fundus camera 1
Can be determined based on whether or not a filter is inserted into the imaging system or the illumination system.

FIG. 6 shows a screen of the television monitor 5a for selecting essential information in the third embodiment, which is required from the information of the examinee such as the examinee ID number, examinee name, date of birth, gender, left and right eyes, and the like. Select information. In addition, when the photographing is performed, the photographing is not permitted unless the essential information selected on the essential information selection screen is input in advance. By enabling the setting of the essential information in this way, it is possible to prevent the occurrence of an unmanageable image without the patient information.

FIG. 7 is a flow chart of the present embodiment, in which when a radiographing switch is pressed after selecting a radiographing mode and inputting patient information, the examinee information selected on the essential information selection screen is displayed. A check is performed to determine whether or not the necessary information has been input. If the required information has been input, the process ends after taking a picture as in the related art. However, if the essential information has not been input, the screen shifts to the patient information input screen without shifting to the imaging control. Further, an error display may be displayed, and when the error display is performed, photographing may be performed.
