Abstract
Clear Fundus Images Through High-Speed Tracking Using Glare-Free IR Color Technology

Glare-free IR color fundus camera

Fundus images contain extensive health information. However, patients hardly obtain their fundus images by themselves. Although glare-free infrared (IR) imaging enables easy acquisition of fundus images, it is monographic and challenging to process in real-time in response to high-speed and involuntary fixational eye movement and in vivo blurring. Therefore, we propose applying our IR color technology and providing clear fundus images by high-speed tracking of involuntary fixational eye movements and eliminating in vivo blurs by deconvolution. We tested whether the proposed camera system was applicable in medical practice and capable of medical examination. We verified the IR color fundus camera system could detect ophthalmological and lifestyle-related diseases.
