Abstract

PURPOSE: To surely attain highly frequent image pickup device regardless of image pickup requiring a huge amount of image data. CONSTITUTION: An eyeground image picked up by an eyeground camera 1 such as a CCD camera is inputted from the eyeground camera 11, and a range to limit an aperture mask image is decided based on image pickup information for the image pickup and patient information to select image storage area information to be stored in the image storage device 12 among sets of image storage area information stored in advance in an image storage area storage device 14. The image storage device 12 stores the picked-up image according to the selected image storage area information and the image is displayed on a television monitor 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ophthalmic image storage device for storing an image of an eye to be examined as a digital image.

[0002]

2. Description of the Related Art Due to recent advances in digital image technology,
In the medical field as well, expectations for digital images are increasing and they are being put to practical use. FIG. 5 is a block circuit configuration diagram of a conventional digital image system. The output of a fundus camera 1 equipped with a CCD camera and the like is sequentially connected to an image storage device 2 and a television monitor 3.

When the examiner photographs the fundus of the subject's eye with the fundus camera 1, the fundus image captured by the fundus camera 1 is digitized by the image storage device 2 and then stored as a digital image. It is displayed on the TV monitor 3.

Recently, fluorescent fundus photography or the like has been performed using such a digital image system, and a high-definition monochrome CC is provided in the fundus camera 1 so that details can be read.
A D camera is connected, and the state of circulation of blood vessels in the fundus of the eye is photographed at a high frequency of about one image per second.

[0005]

However, in the above-mentioned conventional example, it takes a considerable amount of time to transfer and store a large amount of image data output from a high-definition CCD camera to the image storage device 2. It is an obstacle for shooting with frequency. Particularly in the case of photographing a fundus image, a mask for clearly indicating the photographing angle of view is usually imprinted, and the black data indicating the mask portion also occupies a considerable amount of image data.

The object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide an ophthalmic image storage device capable of reliably performing high-frequency shooting regardless of shooting with a large amount of image data.

[0007]

An ophthalmic image storage device according to the present invention for achieving the above object includes at least one image input means for inputting an image of an eye to be inspected, and the image input means. Image storage area storage means for storing image storage area information indicating the effective range of the image, and the image storage area information stored in the image storage area storage means in the image input from the image input means. And an image storage unit that stores only image data.

[0008]

In the ophthalmic image storage device having the above-mentioned structure, the image input means inputs the image of the eye to be inspected, and only the image data of the image storage area information stored in the image storage area storage means is stored by the image storage means. To do.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail based on the illustrated embodiments. FIG. 1 is a configuration diagram of the embodiment, and the output of a fundus camera 11 equipped with a CCD camera or the like is the image storage device 1.
2. An image storage area storage device 14 in which image storage area information of image data to be stored in the image storage device 12 is stored in advance between the fundus camera 11 and the image storage device 12 which are sequentially connected to the television monitor 13. Are connected.

FIG. 2 is a flow chart of a concrete operation procedure. In step 1, the examiner operates the fundus camera 11 to take a fundus image, a retina image, etc. of the eye to be examined, and an image P is taken by the fundus camera 11. An image is picked up by a CCD camera or the like as shown in FIG. In addition, photographing information such as the type of fundus camera 11, photographing angle of view, CCD camera type, and patient information is input to the image storage area storage device 14.

In step 2, the range for limiting the aperture mask image is determined based on the imaging information and the patient information, and the image storage device 12 is selected from the image storage region information stored in the image storage region storage device 14 in advance. Select the image storage area information to be stored in.

Here, this selection may be performed automatically, or a keyboard or mouse (not shown) may be selected from the image storage area information displayed on the television monitor 13 connected to the image storage area storage device 14. The command input device may be used for selection.

In step 3, the image P taken in step 1 is taken in accordance with the image storage area information selected in step 2.
Is stored in the image storage device 12 as an image in which the aperture mask image as shown in FIG. 4 is limited, and the stored image is displayed on the television monitor 13.

[0014]

As described above, the ophthalmic image storage device according to the present invention is stored in the image storage area storage means when the image data input from the image input means is stored in the image storage means. By storing the image data based on the image storage area information, only the necessary image data of the eye to be inspected is stored, so the amount of data can be minimized. Moreover, even if the amount of data to be handled is enormous, it is possible to reliably perform high-frequency shooting.
