Flicker mitigation using an event-based camera

Abstract

The invention relates to a method for mitigating flickering lights in a scene of interest imaged by an event-based camera, wherein the event-based camera comprises a plurality of pixels, wherein an imaging behaviour of the plurality of pixels is influenced by a set of pixel parameters comprising at least one exposure time parameter and/or at least one digital accumulation parameter, and wherein the method comprises the following steps: 1) operating the event-based camera having an assignment of first values to the set of pixel parameters, said operating providing a plurality of events generated by the event-based camera; 2) reconstructing an image based on at least the generated plurality of events, 3) determining at least one region in the reconstructed image, said determined at least one region corresponding to at least one spatial region in the scene of interest comprising at least one flickering light source active during the operating of the event-based camera, 4) determining a subset of pixel parameters of the set of pixel parameters, which subset of pixel parameters influences imaging behaviour of pixels in the determined at least one region, assigning second values for the determined subset of pixel parameters, which second values are determined to mitigate flicker in the pixels of the determined at least one region, and updating the first values assigned to the subset of pixel parameters with the second values, and 5) further operating the event-based camera with the updated set of pixel parameters. The invention also relates to an assembly and to a vehicle comprising said assembly.
