Claim:
1. An imaging device comprising: a pixel array configured to generate a pixel signal based on incident light, and including a plurality of pixels disposed in a two-dimensional array; a circuit configured to detect a level based on the pixel signal, to generate a division signal corresponding to the detected level, and to amplify the pixel signal based on the division signal; and a plurality of analog-to-digital converters respectively configured to convert the pixel signal to a digital signal, wherein an analog-to-digital converter of the plurality of analog-to-digital converters is respectively disposed at each pixel column, wherein the pixel signal includes a first pixel signal corresponding to a first frame, and a second pixel signal corresponding to a second frame subsequent to the first frame, and wherein the circuit is further configured to detect a level based on the first pixel signal and to amplify the second pixel signal based on the detected level.
