Signal processing device for image pickup apparatus |
摘要 |
A signal processing device is provided which is capable of suppressing a voltage change of a power supply when output signals from a plurality of signal sources are read, and capable of outputting a stable signal at a high sensitivity, and an image pickup apparatus using such a signal processing device is also provided. The signal processing device has: a plurality of terminals connectable to a plurality of signal sources; and a read circuit for converting signals input from the terminals into serial signals and outputting the serial signals, wherein: the read circuit comprises a holding capacitor connected to each of the terminals, a transfer switch for transferring a signal held in the holding capacitor to a common signal line, and a shift register for driving the transfer switch; and a semiconductor layer under the common signal line has a conductivity type opposite to a first conductivity type of a semiconductor substrate. |
