Abstract
A solid-state imaging device includes a pixel array section including a plurality of pixels, a pixel drive line controlling driving the pixels in each row, a signal line reading an analog signal of the pixels in each column, a pixel drive unit driving the pixels to perform a readout through the pixel drive line, and a readout circuit capable of converting the analog signal into a digital signal. At least the number of pixel drive lines or the number of signal lines is more than one, and the pixels of each pixel group are connected to different lines of either the pixel drive lines or the signal lines. The pixel drive unit sequentially drives the pixels in the pixel group at shifted timings, and the readout circuit includes an analog-to-digital converter sequentially receiving analog signals from the pixel group and sequentially converting the analog signals into digital signals.
