<p>A mobile device (100) comprising a processor (338), a camera module (360), and a flash (366) configured to generate at least one of a reduced pre-flash, a standard pre-flash and a flash. The processor (338), in response to receiving an image capture request (202), is configured to receive a brightness value (204) and determine a flash status (206) based on a flash setting with the flash status being one of an off mode, on mode, and auto mode. In the event the flash status is one of the on mode and auto mode, determine whether there is sufficient light to capture an image based at least in part on a comparison of the brightness value and a flash threshold (208). In the event the brightness value is greater than the flash threshold, cause the flash to generate a shortened pre-flash (214) and obtain only a white balance measurement and an auto-exposure measurement during the shortened pre-flash.</p> |
