Abstract
A mobile multimedia device may be operable to crop a series of image samples received during an autofocus operation. Each of the cropped image samples may be scaled by the mobile multimedia device to fit a display unit in the mobile multimedia device. Each of the scaled image samples may then be displayed on the display unit for viewing during the autofocus operation. The received image samples may be cropped based on an operating mode in which the mobile multimedia device is currently operating. The autofocus operation may be initiated utilizing a shutter button in the mobile multimedia device. The autofocus operation may be terminated when a desired focus is achieved. After the autofocus operation is terminated, the mobile multimedia device may be operable to display one or more image samples received after the termination of the autofocus operation for continuous viewing, with or without further cropping and scaling.
