Abstract
An imaging device includes an illumination element; an auto-exposure element; and a processor disabling the auto-exposure element and subsequently disabling the illumination element.
Claims13
A method, comprising:
- disabling an auto-exposure of an imager in response to a first instruction, the auto-exposure ceasing to modify a first set of image capturing settings for the imager;
- and
- disabling, after the auto-exposure has been disabled, an illumination element of the imager, wherein an image capture means of the imager remains active and uses the first set of image capture setting determined prior to the disabling of the auto-exposure to optimize power consumption of the imager;
- re-enabling the illumination element in response to a second instruction;
- and
- re-enabling, after the illumination element has been re-enabled, the auto-exposure, wherein the image capture means of the imager maintains the first set of image capture settings used in prior image capture session as a set of seed values for the auto exposure.
