Description

The present disclosure relates to an ophthalmic image processing equipment for processing the front fundus image.

The present disclosure is directed to an object to provide at least one resolvable ophthalmic image processing equipment of the prior art problems.

In order to solve the above problem, an ophthalmic image processing apparatus according to the first aspect of the present disclosure includes an ocular fundus image acquisition unit that acquires a fundus front image captured by at least one fundus imaging apparatus. In the fundus imaging apparatus, three light receiving elements and reflected light from the fundus, first fundus fluorescence, and second fundus fluorescence having a wavelength range different from the first fundus fluorescence are different from each other. A light branching unit that causes the light receiving element to receive light. A fundus front image based on reflected light from the fundus, a first fluorescent fundus image based on the first fundus fluorescence, and a second fundus fluorescence. A second fluorescent fundus image can be simultaneously captured, and the fundus image acquisition unit has captured a plurality of the fundus front images captured at different timings and the respective fundus front images simultaneously Each of the first fluorescent fundus image and the second fluorescent fundus image is acquired, and the ophthalmic image processing apparatus further detects a positional shift between the plurality of fundus front images captured at different timings. Based on the calculated positional deviation, the positional deviations in the plurality of first fluorescent fundus images and the second fluorescent fundus images captured simultaneously with the respective fundus front images are calculated. comprising a displacement detection means for detecting detect a.

An ophthalmic image processing apparatus according to a second aspect of the present disclosure is an ophthalmic image processing apparatus including fundus image acquisition means for acquiring a fundus front image captured by at least one fundus imaging apparatus, wherein the ophthalmologic imaging apparatus is provided. Shoots simultaneously a first fundus front image captured with light under the first imaging condition and a second fundus front image captured with light under an imaging condition different from the first imaging condition. Both of the first fundus front image and the second fundus front image are fluorescence images of a contrast agent administered to the eye to be examined, wherein the initial contrast phase, the middle contrast phase, and And a display control means for displaying the first fundus front image and the second fundus front image taken in each time phase of the late phase of contrast on the display device in time series.
