Systems and methods for providing depth imaging using a CCD image sensor. In a method for visual imaging and depth imaging, steps include providing a CCD image sensor device arranged to receive light from an optical lens and having an array of pixels and corresponding pixel charge storage elements; providing a light source for transmitting light pulses responsive to a pulse control signal; providing timing signals to configure the CCD image sensor to collect and store charge from the pixel storage elements; and performing a depth calculation using a background charge, a reflected charge, and a depth charge collected in three frame periods for each pixel in the CCD image sensor. A system including a CCD image sensor for use with the embodiments is disclosed. Additional embodiments are disclosed.
