An imaging circuit includes a first vertical trench gate and a neighboring second vertical trench gate. The imaging circuit includes a gate control circuit. The gate control circuit operates in a first operating mode to generate a first space charge region accelerating photogenerated charge carriers of a first charge-carrier type to a first collection contact in and in a second operating mode to generate a second space charge region accelerating photogenerated charge carriers of the first charge-carrier type to the first collection contact. The imaging circuit further includes an image processing circuit which determines distance information of an object based on photogenerated charge carriers of the first charge carrier type collected at the first collection contact in the first operating mode and color information of the object based on photogenerated charge carriers of the first charge carrier type collected at the first collection contact in the second operating mode.
