Abstract:
Methods, systems, computer-readable media, and apparatuses for improved camera flash are presented. In some embodiments, a method includes performing an autofocus technique on a scene to obtain an autofocus output. The method also includes obtaining an ambient light measurement of the scene. The method further includes adjusting a sensitivity of an image sensor based at least in part on the autofocus output and the ambient light measurement. The method additionally includes, after adjusting the light sensitivity of the image sensor, illuminating the scene using a pre-flash.
