Abstract
A solid-state imaging device includes: a pixel array section in which a plurality of pixels including an amplification transistor configured to amplify a signal based on a photoelectric charge in accordance with an amount of received light are disposed; through vertical signal lines of the pixel array section, a bias-current control section configured to turn on or off a bias current supplied to the amplification transistor for each of the vertical signal lines; and a drive control section configured to control the bias-current control section so as to turn on the bias current of the vertical signal line through which a pixel signal is read, and to turn off the bias current of the vertical signal line through which a pixel signal is not read.
