Abstract
An amplitude modulated continuous wave range imaging device has a signaling device configured to emit an intensity modulated illumination signal. An image sensor is configured to capture a plurality of images of a reflection of the modulated illumination signal. The captured images include intensity and/or phase components for a plurality of pixels of the image sensor. Each pixel includes a first modulation terminal having a first capacitive component. A first driver is configured to charge a first set of modulation terminals of the plurality of pixels. A second driver is configured to charge a second set of modulation terminals of the plurality of pixels. A charge transfer circuit is connected between the first set of modulation terminals and the second set of modulation terminals. The charge transfer circuit is configured to transfer charge between the first set of modulation terminals and the second set of modulation terminals.
