Abstract: A digital imaging device, such as a digital camera, minimizes shutter lag by determining some capture parameters, such as focus and exposure settings, before a user of the device has indicated that a photograph is to be taken. The parameters are updated when the device becomes substantially still before the indication that a photograph is to be taken.

Abstract: A data storage medium includes a data structure, called a disk control block, used for administration and control information for the data storage medium. One medium may contain multiple different disk control blocks, each addressing a different function. Each disk control block includes a control block identifier that specifies the function of the disk control block. Each control block also includes a set of standard access control parameters. If a drive encounters an unrecognized disk control block, the drive can still decode the standard control parameters, so that the drive behavior is not inconsistent with the requirements of the unrecognized disk control block.

Abstract: A digital imaging device performs automatic focus and exposure adjustments based on high-resolution frames when a scene change has been detected based on the analysis of low-resolution frames. The digital imaging device reduces battery power consumption while simultaneously shortening shutter lag.

Abstract: Digital cameras and methods that provide for a rapid camera power-on sequence. A warm-sleep state is defined in which the camera and nearly all of its internal components are shut down, yet just enough information is retained within high speed volatile storage and processing units to rapidly return the camera to full operating state. The warm-sleep state is managed to consume a minimum amount of power to keep the vital information intact. Upon receipt of a power-on indication, the camera then transitions from the warm-sleep state to full operation by simply activating the processing units, and continuing operation from the state it was in immediately prior to the power-off request.
