Abstract
A scanning line drive circuit performs not only a sequential scanning function of scanning lines, but also an interlaced scanning function. For instance, in a fluoroscopy mode in which high-speed imaging and real-time imaging are required, the scanning line drive circuit performs interlaced scanning to scan, for example, every other scanning line. With the interlaced scanning, since the scanning lines are scanned one line at a time like the sequential scanning, a variation of charge on a signal line side does not increase during a transition of a scanning line voltage like conventional scanning in which a plurality of scanning lines are scanned simultaneously. It is therefor possible to obtain a good signal-to-noise ratio without an increase in noise due to fluctuations in the scanning line voltage. Moreover, since an increase in the variation of charge in the fluoroscopy mode can be limited by changing a scanning method of the scanning line drive circuit according to an imaging mode, a signal readout circuit does not need to have a complicated structure to limit the increase in the variation of charge.
