1. A digital camera, comprising:

  • an imaging module configured to convert optical images to digital images and further configured to produce a series of digital preview frames in a video preview mode;

    an input control to initiate capture of a digital image by the imaging module; and

    processing logic configured to determine motion of the digital camera,the processing logic being configured to delay capture of the digital image until the determined motion of the digital camera satisfies a motion criterion, and the processing logic being configured to perform an automated image capture adjustment operation;

    wherein the performance of the automated image capture adjustment operation and the determination of the motion of the digital camera by the processing logic are respectively based on picture element values in different respective mutually exclusive regions of each of respective ones of the digital preview frames, wherein for each of the respective ones of the digital preview frames, picture element values from a central window region of the digital preview frame are used for performing the automated image capture adjustment operation and picture element values from a peripheral motion measurement region of the digital preview frame outside the central window region are used for determining the motion of the digital camera.
