Abstract
An imaging element includes: a plurality of pixels where each pixel is configured to generate an imaging signal; a noise eliminating circuit configured to eliminate a noise component included in the imaging signal; a plurality of column source follower buffers where each column source follower buffer is configured to amplify the imaging signal from which the noise component has been eliminated by the noise eliminating circuit, and output the amplified signal; a horizontal scanning circuit configured to sequentially select the column source follower buffer and output the imaging signal; and a buffer circuit which is connected with the column source follower buffer sequentially selected by the horizontal scanning circuit to form a voltage follower circuit, the buffer circuit being configured to perform impedance conversion on a voltage of the imaging signal output from the column source follower buffer, and output the converted signal to an outside.
