Photoarray, particularly for combining sampled brightness sensing with asynchronous detection of time-dependent image data

A photoarray, comprising:

• a plurality of cells (10), wherein
• each of said cells (10) comprises a means (20) that is configured to generate a photocurrent (I) being proportional to the intensity (L) of the light impinging on the respective cell (10), and wherein
• each of said cells (10) comprises a change detection circuit (100) connected to the respective means (20) for generating the photocurrent (I), which change detection circuit (100) is configured to generate an output signal merely in case a change event (30) occurs at which said intensity (L) changes by a threshold amount (T, T′) since the preceding change event (30) from the respective cell (10), wherein the photoarray (1) is additionally also configured to determine the brightness (B′) at the respective cell (10) by means of said means (20) for generating said photocurrent (I), and wherein
• said change detection (100) circuit is configured to generate an output signal if and only if a change event (30) occurs at which said intensity (L) changes by a threshold amount (T, T′) since the preceding change event (30) from the respective cell (10), wherein said output signal is an ON-Signal when said intensity (L) increases by a threshold amount (T) and an OFF-signal when said intensity (L) decreases by a threshold amount (T′).
