Fast luminance measurement method for asynchronous spiking pixels

A new method to obtain a continuous and fast measurement of light intensity is presented. It is targeted for Integrate and Fire pixels that pulse with a frequency proportional to illumination. The procedure is intended to speed up the pixel readout of low illuminated pixels. It does not require sync...

Description
Summary:A new method to obtain a continuous and fast measurement of light intensity is presented. It is targeted for Integrate and Fire pixels that pulse with a frequency proportional to illumination. The procedure is intended to speed up the pixel readout of low illuminated pixels. It does not require synchronisation of different digital signals, being compatible with continuous pixel operation. The fundamentals of this method are described. Experimental results validating the theory are provided.
