… Our event-based autofocus system consists of an event camera and a motorized varifocal …
It leverages the proposed event-based focus measure and search method to focus the camera …

… is closest to our idea, which applies the event camera in AF for small depth-of-focus
microscopes. Interestingly, they found that events were mainly triggered symmetrically at both sides …

… An event camera is a high dynamic range vision sensor that can record slight brightness
changes in autofocus experiments under insufficient lighting. However, it leads to a reduction in …

… In contrast to the light intensity difference sampling mode of event cameras, spike cameras
are developed based on an integration sampling approach. The sampled results in Qs …

… strong connections between the proposed metrics (Table 1) and those used for shape-from-focus
and autofocus in conventional, frame-based cameras [43, 44], and so, we called the …

… Liu Jiawen [12] reviews the evolution of auto-focus methods, illustrating the importance of
hardware in achieving sharp images. Mallick et al. [22] characterize the noise in Kinect depth …

… of a camera with autofocus lenses modifying a well-known camera calibration process
with a set of rules that help to improve the method. Section II analyses the camera calibration …

… achieve fast autofocusing using the neuromorphic event sensing technology, which detects
… and processing of the non-redundant event data, allowing for autofocusing in only tens of …

… [22] designed an auto-focus algorithm for event cameras to find the maximum event triggering
rate timestamp as the refocusing timestamp. However, the majority of events in the EFS …

… Under broadband lighting, the camera’s autofocus mechanism was used to focus the
lens on the target. The temporary target was then removed. Next, a Siemens star square-wave …
