Claim:
1. An image capturing device comprising: an image capturing section having a plurality of pixels disposed in a matrix and configured to output a pixel signal via a first signal line connected to pixels arranged in a first direction among the plurality of pixels; a plurality of calculators, each of which is configured to perform cyclic analog-to-digital (AD) conversion and includes: a latch section configured to latch the first digital value sequence; a β estimation signal output section configured to output the β estimation signal; a β estimation section configured to estimate a value of the amplification degree β based on the first digital value sequence when the β estimation signal is output as the first analog signal; and a binarization section configured to acquire a second digital value sequence which is a binary number, based on the first digital value sequence and the estimated value of the amplification degree β, wherein the plurality of calculators are disposed one by one in correspondence with one or more columns of an array of the plurality of pixels; the β estimation signal output section is disposed in correspondence with two or more of the plurality of calculators; the β estimation section is disposed in correspondence with two or more of the plurality of calculators; and the binarization section is disposed in correspondence with two or more of the plurality of calculators.
