This specification discloses an image scanning system in which an object image formed by an optical system is electrically scanned by utilization of a photosensor array device and the image scanning output then obtained is quantized to thereby provide quantized image data. According to the improvement of the present invention, there are obtained two different quantized image data, namely, first quatized image data quantized by a voltage level determined on the basis of the image scanning output from the sensor device and second quantized image data quant...
In a focusing system, a focus detecting device comprising: (A) signal integration type image scanning means for scanning a detection image of an object onto which the focusing system should be focused and for producing a scanned image signal representative of said detection image, said scanning means integrating each signal over a controlled signal integration time; (B) drive means for repetitively driving said image scanning means so that said scanning means repetitively scans said detection image and produces the scanned image signals repetitively; (C)...
