  • Solid-state imaging device, method for driving solid-state imaging device, and electronic apparatus
    Patent number: 11849235
    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 part 400 includes a first reading part 410 and a second reading part 420. Of a pixel signal PIXOUT input into an input node ND401, the first reading part 410 inverts 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 part 430 via a connection node ND402. Of the pixel signal PIXOUT input into the input node ND401, the second reading part 420 keeps 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 part 430 via the connection node ND402.
