Abstract
The imaging apparatus includes an image sensor circuit comprising a time of flight sensor pixel. The imaging apparatus further includes a first light emitter having a first spatial offset relative to the time of flight sensor pixel. The imaging apparatus further includes a second light emitter having a second spatial offset relative to the time of flight sensor pixel. The imaging apparatus further includes an image processing circuit configured to produce an image of a region of an object based on first sensor pixel image data and second sensor pixel image data generated by the time of flight sensor pixel. The first sensor pixel image data is based on received light emitted by the first light emitter and reflected at the object's region and wherein the second sensor pixel image data is based on received light emitted by the second light emitter and reflected at the object's region.
