Abstract: A close-up imaging device that generates slit light on the basis of light-source light emitted from a light source built into a mobile communication terminal device. The close-up imaging device is mounted onto the mobile communication terminal device, and a moving image of the tissue to be observed of the examined eye is captured by a camera module built into the mobile communication terminal device. Then, in a diagnosis support server device, a diagnosable frame image included in the captured moving image is extracted, at least one of a heath state of the examined eye and any one or more of a distance, an angle, and an area in some tissue of the examined eye is estimated on the basis of the diagnosable frame image extracted, and diagnosis support information is generated and distributed to the corresponding mobile communication terminal device.

Abstract: To provide a close-up imaging device whereby both imaging of an anterior eye and imaging of an eye ground can easily be performed by attaching the device to a mobile terminal such as a smartphone. The above-described problem is solved by a close-up imaging device (1B) detachably mounted to a mobile terminal (9) equipped with a light source (92) and a camera lens (91) for imaging, comprising a color filter member (97) detachably provided above the light source (92), and a convex lens member (93) detachably provided above the camera lens (91). Imaging, of an anterior eve is performed by removing the color filter member (97) and attaching the convex lens member (93), and observation of an injury of the anterior eye is performed by attaching the color filter member (97) and the convex lens member (93).
