Abstract: An imaging element includes: a plurality of pixels arranged into a two-dimensional matrix, configured to receive light from outside, and configured to generate and output an imaging signal according to an amount of light received; a first transfer line connected to the pixel and configured to transfer the imaging signal; a pixel selection unit configured to perform a selection operation of selecting a selection target pixel from among the plurality of pixels in order to read the imaging signal out to the first transfer line and a de-selection operation of canceling the selection of the pixel being selected; and control unit configured to control the pixel selection unit. The control unit performs the selection operation of selecting a new selection target pixel after performing the de-selection operation on the basis of a synchronization signal from outside.
