Solid-state image device, method of driving solid-state imaging device, and electronic system with switching between first and second modes

摘要

A solid-state imaging device includes a pixel array section that includes an amplification transistor configured to amplify a signal based on a photoelectric charge in accordance with an amount of received light. Through vertical signal lines of the pixel array section, a bias-current control section is configured to turn on or off a bias current supplied to the amplification transistor for each of the vertical signal lines. A drive control section is configured to control the bias-current control section. In one example, the drive control section controls switching modes between a first mode in which pixel columns whose pixel signals are read are changed in time series, and a second mode in which pixel signals of all the pixel columns are read and then the pixel signals of the plurality of pixel columns are smoothed.
