Abstract
A computational sensing array includes an array of sensing elements. In each sensing element, a first signal is generated from a transducer. A second signal is produced by a collection unit in response to receiving the first signal. The second signal may be modified, in a conditioning unit. A sensing element preprocessing unit generates a word representing the value of the modified second signal, and may produce an indication of change of the first signal. A current value of the word may be stored in a state holding element local to the sensing element, and a previous value of the word may be retained in a further state holding element local to the sensing element.
