Abstract
An apparatus comprising a sensor, a motion detector, a memory and a processor. The sensor may be configured to capture a first image. The motion detector may be configured to initiate the capture of the first image. The memory may be configured to store exposure data associated with the first image. The processor may be configured to determine if the stored exposure data is usable to capture a second image.
Claims19
An apparatus comprising:
- a memory configured to store an exposure data associated with a first image captured from a sensor prior to said apparatus entering a power down state;
- a motion detector configured to initiate (i) a capture of a second image using said stored exposure data and (ii) a power on of one or more input sensors configured to gather information during a system boot time after said apparatus exits said power down state;
- and
- a processor configured to determine if said stored exposure data from said first image is usable to calibrate exposure data used to capture future images from said sensor based on said information, wherein (i) said future images are captured without calculating said exposure data if said stored exposure data is determined to be usable and (ii) said determination of whether said stored exposure data is usable occurs during all or part of the time during the capture of said second image.

A method for reducing the time needed for capturing a target image comprising the steps of:
- capturing a first image in response to a motion detector;
- storing exposure data associated with said first image in memory prior to entering a power down state;
- initiating (i) a capture of a second image using said stored exposure data and (ii) a power on of one or more input sensors configured to gather information during a system boot time after exiting said power down state;
- and
- using a processor for determining if said stored exposure data from said first image is usable to calibrate exposure data used for capturing future images based on said information, wherein (i) said future images are captured without calculating said exposure data if said stored exposure data is determined to be usable and (ii) said determination of whether said stored exposure data is usable occurs during all or part of the time during the capture of said second image.
