摘要
The present invention relates to a photo array (1), comprising a plurality of cells (10), each of the cells (10) comprising a photocurrent I (I) proportional to the intensity L And wherein each of the cells (10) comprises a change detection circuit (100) connected to a respective means (20) for generating the photocurrent (I) And the change detection circuit 100 generates an output signal only when a change event occurs in which the intensity L changes by a threshold value T or T ''after a preceding change event from each cell 10 . According to the invention, the means 20 for generating the photocurrent I is additionally used for estimating the magnitude of the photocurrent I, which is a measure of the brightness of the light of each cell 10.
