DETECTION OF CODED LIGHT

摘要

A camera of a device captures an image of a scene comprising light from a light source, wherein the light from the light source is modulated with a coded light component. The camera comprises an image capture element divided into a plurality of lines, whereby to capture the image the lines are exposed at different times in sequence. A processing module is configured to detect an orientation of the light source as projected onto the plane of the image capture element relative to the lines of the image capture element, and based thereon to determine a target reorientation of the device for a footprint of the light from the light source to cover an increased number of said lines in the image. The user interface is configured to output an indication of the target reorientation to the user, inducing the user to enact the target reorientation.
