Problems solved by technology

However, these images taken in batches often have different exposures due to different shooting time points, which is not conducive to the subsequent fundus image merging
Moreover, in the process of taking multiple shots, due to the long shooting time, it often causes a burden on the patient's eyes, and there may even be a short-term nystagmus that makes the fundus image blurred.

Embodiment Construction

[0060] figure 1 is a schematic diagram of an imaging device in an embodiment of the present invention. Please refer to figure 1 , in this embodiment, the camera device 100 is suitable for capturing images of the eye E, and the camera device 100 includes an image sensing unit 110 and a lens group 120 . The lens group 120 is disposed between the image sensing unit 110 and the eye E, and can project light from the eye E to the image sensing unit 110, wherein the lens group 120 and the image sensing unit 110 can move relative to the eye E accordingly, And it is possible to take multiple images of multiple parts of the eye E in a continuous shooting manner. In this embodiment, the mode of continuous shooting is, for example, a mode in which the camera can repeatedly shoot at a set interval, that is, when the shooting button is pressed once, the camera can continuously take multiple photos. When the interval is short, the captured images can be regarded as continuously captured i...

Abstract

The invention provides a photographic device and method used for acquiring eye images. The photographic device comprises an image sensing unit, a lens group and a processing unit. The lens group is arranged between the image sensing unit and the eyes and used for projecting light from the eyes to the image sensing unit, the lens group and the image sensing unit move relative to the eyes correspondingly to shoot a plurality of parts of the eyes in a continuous capturing mode to obtain a plurality of images. The processing unit is electrically connected with the image sensing unit and splices the images.

Description

technical field [0001] The invention relates to an imaging device and an imaging method. Background technique [0002] Modern people often need to use their eyes to read or watch a lot of screens in their daily life, unknowingly causing excessive eye use, which leads to various eye symptoms. Among them, eye diseases such as retinal detachment, macular hemorrhage or angiogenesis will seriously affect the patient's vision. Therefore, checking the state of the retina, macula, and optic disc located in the fundus has always been an important part of eye health checkups. [0003] Since the retina, macula, or optic disc are all located in the fundus, the fundus is usually observed or photographed through the pupil of the eye during examination. However, generally speaking, normal human eyes have narrow pupils, so it is difficult to see the whole picture of the fundus in one shot. Therefore, in actual testing, medical staff usually ask the patient to stare at a fixed point to wa...
