Method for increasing resolution of array sensor and system therefor

摘要

The resolution of an array sensor can be increased by projecting images of picture elements, which lie on the same scanning line, on a plurality of one-dimensional array sensors composed of a number of photoelectric transducers arranged with an equal interval in a row; and then subjecting picture signals, which have been output respectively from the array sensors, to a combination processing so as to obtain continuous picture signals. It is possible, without using any memory unit, to output picture signals with a resolution higher than that available from the use of a single one-dimensional array sensor, namely, with a resolution proportional to the number of a plurality of one-dimensional array sensors.
