Abstract
Endoscopy and small surgery can be performed with the support of small cameras. These cameras need to be minimal to reduce intrusion, require fast response and automatic illumination. The current work describes the world's smallest camera for endoscopy, NanEye, and the dynamic control algorithm for ROI developed for the illumination LED source coupled to the camera head that allows adjusting light, gain and exposure time. The obtained results show that it is capable of achieving correction speeds under 1 s while maintaining a static error below 3% relative to the total number of pixels of the image. The result of this work will allow the integration of high brightness LED sources of millimeter size on a very small camera enabling its use in endoscopic surgical robotic operations or minimal invasive surgery and NanEye is expected to be supplied at low prices for single time use.
