摘要： An image sharpness detecting system employing two photoconductive cells of different geometry which permits detection of an optimum degree of sharpness of an image formed thereon regardless of variation in the direction of light distribution of the image relative to the electrodes of the cells. Differences between light response characteristics of these two cells due to the different geometry thereof are compensated for by providing optical means such as filter arranged between the cells, whereby the system is made accurately and reliably responsive to variation of light distribution even at low total light levels.
