1. A camera for capturing images of an object, the camera comprising: a single image sensor including an array of uniformly and continuously spaced light-sensing pixels; a plurality of lenses that focus light transmitted from an object onto a plurality of different pixel regions of the image sensor, each lens focusing light on a different one of the pixel regions; and a controller, including a processor and an object detection module, coupled to the single image sensor that: analyzes the pixel regions to generate a three-dimensional (3D) image of the object through a plurality of images successively obtained with the image sensor; generates a depth map that calculates depth values for pixels of at least the object, based on the images received in the different pixel regions; detects 3D motion of the object using the depth values; creates a reconstructed 3D model of the object based on the 3D image; and tracks 3D motion of the object based on the 3D model.
