<P>PROBLEM TO BE SOLVED: To avoid image quality degradation arising from the correction for leak current of a TFT switch in an image signal readout method for reading out an image signal from an image detector including multitudes of pixels, each having a TFT switch, disposed two-dimensionally. <P>SOLUTION: A leak level flowing out to each of the data lines is detected with a signal for switching OFF TFT switches being applied to each of the scanning lines prior to reading out the image signal. Then, a correction of the image signal is performed based on the leak level only when the leak level exceeds a predetermined threshold value, and the correction of the image signal based on the leak level is not performed when the leak level is not greater than the threshold value. <P>COPYRIGHT: (C)2008,JPO&INPIT |
