Abstract
An image sensing system comprises an array of photosensors each adapted to sense the light intensity in a respective portion of an image, and circuitry for scanning the photosensor in the array including a plurality of pulse generation circuits corresponding to respective photosensors and each providing a pulse delayed with respect to the beginning of a scanning operation by an interval approximately inversely proportional to the light intensity sensed by its corresponding photosensor. In addition, the system includes a plurality of memory storage locations, each one associated with a respective photosensor and its corresponding pulse generation circuit, and adapted to store a multiple bit code. Furthermore, the system includes circuitry which analyzes the sequential order in which the delayed pulses of the pulse generation circuits are provided and causes to be stored in each of the memory locations a code indicative of the position of the pulse generation circuit associated with the memory location in the aforementioned sequential order. Since the order in which the pulse generation circuits provide their respective pulses is dependent on the light intensities sensed by their corresponding photosensors, the code stored in each memory location indicate the order of the light intensity sensed by the photosensor associated with the memory location.
