Field: Computer technology (Electrical engineering)
Classification: CPC G  B | IPC B  G

Claim 5:
6. A method for filtering a plurality of event data, the method comprising:
emitting towards a scene a transmitted light modulated by a reference signal frequency;
receiving the plurality of event data, each comprising a change in a light intensity of a pixel, wherein the pixel is part of an image of the scene reflecting the transmitted light;
determining, for each event data in the plurality of event data, a frequency of the change in the light intensity of the pixel over time;
identifying a select event data from the plurality of event data based on whether the frequency of the change in the light intensity is substantially the same as the reference signal frequency; and
filtering a filter event data from the plurality of event data based on whether the frequency of the change in the light intensity is not substantially the same as the reference signal frequency.
