Abstract
PURPOSE:To obtain an accurate picture with one-time photoelectric converting action by transferring signal charges in a first accumulation period by means of a charge coupled element so as to read them, and setting the accumulation time of a second accumulation period in accordance with the size of the signal charges. CONSTITUTION:A time T1 is selected so that the linear CCD image-pickup element 1 is not made over-flow by the first photoelectric conversion and charge accumulation in the maximum strength of incident light beams. The strength of the incident light beams are detected by the amplitude of outputs which can be obtained by the first photoelectric conversion and charge accumulation, and the termination time t3 of a time period T2 in which the second photoelectric conversion and charge accumulation which is started from a time t1 are executed is obtained. Thus, a picture signal whose sensitivity is controlled by an accurate accumulating at one period of the action of the linear CCD image-pickup element 1.
