Systems and methods for fast video capture and sensor adjustment

A portable electronic device comprising:

• a frame;
• a camera mounted on the frame and configured to capture and process image data according to a plurality of image capture parameters;
• an input mechanism provided on the frame and configured for receiving se input to control operation of the camera, the input mechanism being disposable by a user between an engaged condition and a disengaged condition;
• and
• a camera controller incorporated in the frame and configured to perform an automated bracketing action with respect to a first plurality of images captured, the camera comprising:
• receiving, at the input mechanism of a wearable camera device, a user input to initiate capture of first video data;
• capturing the first plurality of frames using camera settings based on a set of auto bracketing settings in response to the user input, each frame of the first plurality of frames have associated camera settings which are different for each frame of the first plurality of frames, and the associated camera settings are determined from the set of auto bracketing settings;
• processing, in response to the user input, a set of sensor data to determine a set of camera setting values for an environment of the wearable camera device;
• selecting the camera settings for the wearable camera device using the set of camera setting values after the first plurality of frames are captured;
• capturing a second plurality of frames with the camera settings selected using the set of camera setting values;
• selecting at least a first frame of the first plurality of frames for inclusion with the first video data based at least in part on the associated camera settings for the first frame;
• and
• storing the first video data as a data file comprising the first frame and the second plurality of frames;
• wherein the set of sensor data comprises the first plurality of frames;
• and
• wherein the set of camera setting values comprises:
• a number of blacked out pixels for each frame of the first plurality of frames;
• a number of low-luminosity pixels for each frame of the first plurality of frames, each low-luminosity pixel having a luminosity value lower than a predefined threshold;
• an average luminosity value for pixels in each frame of the first plurality of frames;
• and
• a median luminosity of pixels and macro-pixels in each frame of the first plurality of frames.

A non-transitory computer-readable storage medium having stored thereon instructions that, when executed by a wearable camera device, cause the wearable camera device to perform operations comprising:

• detecting a user engagement with an input mechanism forming part of a portable electronic device having an on-board camera configured to capture and process image data according to a plurality of image capture parameters, the user engagement comprising disposal of the input mechanism from a disengaged condition to an engaged condition;
• processing, in response to the user input, a set of sensor data to determine a set of camera setting values for an environment of the wearable camera device;
• capturing a first plurality of frames using camera settings based on a set of auto bracketing settings in response to the user input, each frame of the first plurality of frames having associated camera settings which are different frame each frame of the first plurality of frames, wherein the associated camera settings are determined from the set of auto bracketing settings;
• selecting the camera settings for the wearable camera device using the set of camera setting values after the first plurality of frames are captured;
• capturing a second plurality of frames with the camera settings selected using the camera settings;
• selecting at least a first frame of the first plurality of frames for inclusion with the first video data based at least in part on the camera settings for the first frame;
• and
• storing the first video data as a data file comprising the first frame and the second plurality of frames;
• wherein the set of sensor data comprises the first plurality of frames;
• and
• wherein the set of camera setting values comprises:
• a number of blacked out pixels for each frame of the first plurality of frames;
• a number of low-luminosity pixels for each frame of the first plurality of frames, each low-luminosity pixel having a luminosity value lower than a predefined threshold;
• an average luminosity value for pixels in each frame of the first plurality of frames;
• and
• a median luminosity of pixels and macro-pixels in each frame of the first plurality of frames.
