1. A mobile computing device, comprising:
a camera arrangement comprising:
an image capture device;
a plurality of illumination elements configured to emit light;
a controller for the plurality of illumination elements, wherein during capture of an image by an image capture device, the controller is configured to:
evaluate light emitted by the plurality of illumination elements, reflected by one or more objects or object portions and detected at the image capture device to determine respective reflectivity values for the one or more objects or object portions;
determine an illumination pattern for the light source module based, at least in part, on the respective reflectivity values determined for the one or more objects or object portions, wherein the one or more objects comprise a target object and a bounce object; and
cause individual ones of the plurality of illumination elements to respectively emit light to generate the determined illumination pattern, wherein the individual ones of the plurality of illumination elements are respectively configured to emit different amounts of light based, at least in part, on the respective reflectivity values determined for the one or more objects or object portions, wherein a first portion of the plurality of illumination elements is configured to emit a first amount of light based, at least in part, on a reflectivity value for the bounce object and wherein light emitted by the first portion of the plurality of illumination elements is reflected by the bounce object to the target object, then reflected from the target object to the image capture device.
