A method and system for determining a camera-to-display latency of an electronic device ( 100 ) having a camera ( 134 ) and touch-sensitive display ( 108 ) are disclosed. In one example embodiment, the method ( 500 ) includes receiving ( 511 ) first light ( 136 ) at the camera, and essentially simultaneously receiving second light ( 138 ) at a first photosensitive structural portion ( 102, 602 ). The method ( 500 ) further includes detecting ( 512 ) a first simulated touch input at the display ( 108 ) in response to a first actuation of the first photosensitive structural portion ( 102, 602 ), receiving third light ( 140 ) at a second photosensitive structural portion ( 104, 604 ), the third light being generated based at least indirectly upon the received first light ( 136 ), detecting ( 514 ) a second simulated touch input at the display ( 108 ) as a result of the receiving of the third light ( 140 ), and determining the camera-to-display latency based at least indirectly upon the touch inputs ( 516 ). |
