Abstract
A mobile terminal can include a flash coupled to a mobile terminal housing and configured to provide light from the mobile terminal to illuminate a subject. An image sensor circuit is coupled to the flash and includes a plurality of first image sensing elements configured to provide image data representative of the subject. A flash sensing circuit is coupled to the image sensor circuit and is configured to measure the light provided by the flash using second image sensing element in image sensor circuit. Related cellular radiotelephones and methods are also disclosed.
