Abstract
Provided are a solid-state imaging device, a method for driving a solid-state imaging device, and an electronic apparatus capable of reading signals produced with different conversion gains and having different signal directions. A pixel signal processing partincludes a first reading partand a second reading part. Of a pixel signal PIXOUT input into an input node ND, the first reading partinverts the signal direction of a first-conversion-gain signal (HCGRST, HCGSIG) and outputs an inverted first-conversion-gain signal (HCGRST, HCGSIG), which has been subjected to inversion and amplification, to an AD converting partvia a connection node ND. Of the pixel signal PIXOUT input into the input node ND, the second reading partkeeps the signal direction of a second-conversion-gain signal (LCGSIG, LCGRST) unchanged, and outputs a non-inverted second-conversion-gain signal (LCGSIG, LCGRST) to the AD converting partvia the connection node ND
