Abstract

Event-Based (EB) cameras generate events in response to relative changes in light. The primary characteristics of an EB camera are its sensitivity to light changes and the latency of change detection. These parameters, and consequently the camera’s response, are strongly impacted by the lighting conditions. Both temporal and spatial light contrast affect detection capabilities, as spatial contrast translates into temporal contrast for moving objects. When an EB camera fails to resolve objects with high spatial frequency textures, the spatial contrast transfer degrades, impacting temporal contrast and data quality. This preliminary work is an initial step in evaluating the ability of EB cameras to transfer contrast at high spatial frequencies.
