Abstract

We present in this paper a new readout technique designed in order to control the dataflow outgoing from a logarithmic image sensor. It is based on the reduction of the temporal redundancies in the streaming video frames. The main idea is to distribute the sensor into blocks of NxN pixels, then each block generates the mean value of the luminosities signals of all its pixels, this mean values are converted and stored in a digital memory. A comparison between two averages vectors of two successive images point out the addresses of the blocks that must be entirely read and updated in the following frame.
