Problems solved by technology

[0005] Traditional desktop fundus cameras include complex lighting systems and observation systems, which are huge in size and complex in system structure; some instruments require special software installed on a computer before they can be used, and the machines themselves do not have image storage functions, and some even cannot be separated from the computer Work independently
If pictures are needed, the patient needs to go to the instrument to take fundus pictures, whi

Abstract

The invention discloses a handheld type fundus camera used for fundus examination on human eyes medically. Human-eye fundus images are obtained through the optical imaging method in order to judge pathologies and focuses of fundus diseases. According to the handheld type fundus camera, a near-infrared LED and a white light LED are adopted as lighting light sources, optical lenses are used for collecting the fundus images, a CCD or COMS is used for receiving signals, and the human-eye fundus images are displayed on a screen through image transmission and processing. The handheld type fundus camera is simple in structure and capable of being carried around; a manual focusing mode can be adopted, imaging is clear and real-time image transmission can be achieved.

Description

technical field [0001] The present invention relates to a hand-held fundus camera, in particular to a large field of view fundus camera based on LED lighting and CCD\COMS imaging. Near-infrared and white LEDs are used as illumination sources to collect human fundus images through optical lenses. CCD or CCD COMS receives the signal and displays the fundus image of the human eye on the screen through hardware and software image processing. [0002] The invention belongs to the field of medical technology, and takes images of the fundus of the human eye, which are used for the screening of fundus diseases and assisting the diagnosis and condition judgment of other systemic diseases in the whole body, and involve image acquisition, image processing, network transmission and other technologies. Background technique [0003] LED light source is a new lighting method that has appeared in recent years. Compared with traditional light sources, LED has the advantages of long life, ene...
