Abstract
PURPOSE:To remove the dark signal of a photo-electric converting element or the unnecessary component of a driving noise, etc., from a reading signal by controlling of a connecting reletion between a first capacitor to accumulate the reading signal of a photoelectric converting cell and a second capacitor to accumulate a remaining signal after a refresh. CONSTITUTION:The reading signals of respective photoelectric converting cells S are accumulated to respective capacitors C1 and C2 and continuously, the capacitor C2 is cleared. The respective photoelectric converting cells are refreshed and the remaining signals of the respective photoelectric converting cells after the refreshing are accumulated to the respective capacitors C2. After that, a pulse phih1 is impressed to the gate electrode of a transistor Qh and by the connecting condition of the capacitors C1 and C2 a signal, in which the remaining signal accumulated in the capacitor C2 is subtracted from the reading signal of the photo-electric converting cell S accumulated in the capacitor C1, is realized to an output line HL as an information signal and outputted through an amplifier 2 as an output signal Sout. Thus, the dark signal of the photo-electric converting element or the unnecessary component of the driving noise, etc., can be removed from the reading signal.
