ABSTRACT:
The present invention relates to a system for exposure measurement and/or focus detection by means of image senser such as photo diode array (MOS image senser), CCD (charge coupled devices) consisting of a plural number of adjacently disposed respectively integrated fine light sensing elements whereby the image pattern of the object is scanned purely electrically in such a manner that the then obtained output of each light sensing element is converted into a digital value one after another for processing.
