Abstract
An observation device and method its operation is disclosed. The device includes an instrument with a shaft having a proximal end and a distal end; objective optics disposed at the shaft and having a field of view; an imaging sensor arranged to capture image data, the imaging sensor having a sensor array of evenly distributed elements; and an image processing unit. The objective optics is arranged to capture a scene in the field of view on the imaging sensor. The objective optics define at least a central imaging region and a peripheral imaging region, where the differing focal lengths of the objective optics result in the central imaging region having a higher digital resolution than that of the peripheral region, resulting in more pixels dedicated to the region of interest, while the peripheral regions have adequate resolution to monitor the introduction of surgical tools and other valuable information.
