Abstract
A method for acquiring intensity images through a dynamic vision sensor is provided, the method including resetting an inner state of each of a plurality of pixels in the dynamic vision sensor to a predetermined value; receiving from at least one of the plurality of pixels an event signal based on a change in its inner state indicative of a difference in amount of light incident upon the at least one of the plurality of pixels versus that corresponding to the predetermined value; and integrating over a time period the received event signal for the at least one of the plurality of pixels to determine the intensity of light incident upon the at least one of the plurality of pixels.
Claims22
A method for acquiring intensity images through a dynamic vision sensor, the method comprising:
- resetting an inner state of each of a plurality of pixels in the dynamic vision sensor to a predetermined value;
- receiving from at least one of the plurality of pixels an event signal based on a change in its inner state indicative of a difference in amount of light incident upon the at least one of the plurality of pixels versus that corresponding to the predetermined value;
- and
- integrating over a time period the received event signal for the at least one of the plurality of pixels to determine the intensity of light incident upon the at least one of the plurality of pixels.
(canceled)
An image acquisition device comprising:
- a dynamic vision sensor (DVS) having a plurality of pixels, each pixel having an inner state indicative of light intensity upon that pixel and an event output indicative of a threshold change in its inner state;
- a timing unit connected to the plurality of pixels through a reset circuit, the reset circuit configured to reset the inner states of each of the plurality of pixels upon a signal from the timing unit;
- and
- an integration unit connected in signal communication with the DVS, and further connected to the timing unit through a synchronization circuit, the integration unit configured to form pixel intensity data by integrating events for each of the plurality of pixels, and provide the integrated pixel data as intensity image outputs.
