An imaging apparatus according to the present disclosure includes a plurality of comparing units that compare analog signals supplied from pixels including photoelectric conversion elements through a vertical signal line with reference signals of ramp waves having different inclinations and output comparison results, a plurality of counters that execute counts until the comparison results are inverted for the different comparing units and output count values as digital data, and a sample-and-hold unit that electrically disconnects the vertical signal line and the comparing units and supplies the held analog signals to the comparing units while the comparing units execute the comparisons. The present disclosure can be applied to an imaging element, a control method, and an imaging apparatus.
