<p><P>PROBLEM TO BE SOLVED: To provide a radiographic apparatus which can stably provide a moving image at high speed by suppressing a voltage variation in GND or power supply line and omitting a standby period for each frame. <P>SOLUTION: During a period after electrical signals from conversion elements (S1-1 to S1-3) in one control wiring (G1) are transferred and read for each row by a drive circuit section (SR1) before electrical signals in the next control wiring are transferred and read, the read-accessed conversion elements are refreshed for each row, thereby eliminating the necessity for preparing a refresh period in acquiring continuous moving images. In addition, since the conversion elements are refreshed for each row, the dark current (transient current) in the refresh mode can be made small as compared to a case wherein all the conversion elements are refreshed at once. By this arrangement, the voltage variation in the GND or power supply line is suppressed. <P>COPYRIGHT: (C)2004,JPO</p> |
