More Information
Summary:A three-dimensional (3D) image sensor device and an electronic apparatus including the 3D image sensor device are provided. The 3D image sensor device includes: a shutter driver that generates a driving voltage of a sine wave biased with a first bias voltage, from a loss-compensated recycling energy; an optical shutter that varies transmittance of reflective light reflected from a subject, according to the driving voltage, and modulates the reflective light to generate at least two optical modulation signals having different phases; and an image generator that generates 3D image data for the subject which includes depth information calculated based on a phase difference between the at least two optical modulation signals.
