Abstract
A digital camera of a mobile device acquires images for decoding optical patterns in a scene. Sensor data is used to ascertain a state of the mobile device. Battery life is estimated based on the state of the mobile device. A frame rate of the camera is changed from a first frame rate to a second frame rate to conserve battery life while still providing responsive camera performance.
