Solid-state imaging device, imaging device, and distance measuring device

A solid-state imaging device (200) is provided with: a plurality of pixels (211); a first sample-and-hold circuit (241) that is provided for each column and generates a first differential voltage that is the difference between a first reset voltage output from a first pixel disposed in the corresponding column and the first signal voltage; a second sample-and-hold circuit (242) that is provided for each column and generates a second differential voltage that is the difference between a second reset voltage output from a second pixel different from the first pixel and a second signal voltage; and AD conversion circuits (218) which are provided for each column, and which convert a first voltage based on a first differential voltage output from the first sample-and-hold circuit (241) disposed in the corresponding column, and a second voltage based on a second differential voltage output from the second sample-and-hold circuit (241) disposed in the corresponding column, to a digital signal. The second voltage is
