Abstract

PURPOSE:To obtain a photoelectric conversion signal which is in fidelity with the optical information of a draft by integrating the brightness of a light source during the period photoelectric conversion elements are storing optical information, and by controlling the amplification factor of the output of a photoelectric-conversion- element arrays by the integrated result. CONSTITUTION:The amount of integration of an integrator 8 is reset by the first pulse from a terminal B, and the output of a photosensor 7 is integrated by the integrator 8 until the second pulse is applied. When the second pulse is given, the integrator 8 closes the input port, or holds the amount of the integration at that time, and sends out the output corresponding to the integrated amount. Depending on this output, the amplification factor of an AGC amplifier 6' is controlled in inversely proportional to the stored amount, thereby the output signal, wherein variation in light intensity of a light source is compensated, can be obtained.
