Abstract
An image capture device may receive GPS data during capture of video frames. GPS data may be used to increase accuracy of GPS time of the image capture device. GPS time of the image capture device at a later moment in the capture duration may be used to determine the times of earlier captured video frames.
Claims20
An image capture device for utilizing Global Positioning System (GPS) timing, the image capture device comprising:
- a housing;
- an image sensor carried by the housing and configured to generate a visual output signal conveying visual information based on light that becomes incident thereon, the visual information defining visual content;
- an optical element carried by the housing and configured to guide light within a field of view to the image sensor;
- a GPS receiver carried by the housing and configured to receive GPS signals from GPS satellites, the GPS signals conveying broadcast times of the GPS signals, wherein GPS time of the image capture device is determined based on difference between the broadcast times of the GPS signals and reception times of the GPS signals;
- one or more physical processors carried by the housing, the one or more physical processors configured by machine-readable instructions to:
- capture the visual content during a capture duration, the captured visual content contained within video frames, the video frames including an initial video frame containing the visual content captured at a beginning moment in the capture duration, a later video frame containing the visual content captured at a later moment in the capture duration, the later moment subsequent to the beginning moment, and intermediate video frames containing the visual content captured between the beginning moment and the later moment in the capture duration;
- determine times for the initial video frame and the intermediate video frames based on the GPS time of the image capture device for the later video frame;
- and
- associate the determined times for the initial video frame and the intermediate video frames with the initial video frame and the intermediate video frames.
A method for utilizing Global Positioning System (GPS) timing, the method performed by an image capture device including one or more processors, an image sensor, an optical element, and a GPS receiver, the image sensor configured to generate a visual output signal conveying visual information based on light that becomes incident thereon, the visual information defining visual content, the optical element configured to guide light within a field of view to the image sensor, the GPS receiver configured to receive GPS signals from GPS satellites, the GPS signals conveying broadcast times of the GPS signals, wherein GPS time of the image capture device is determined based on difference between the broadcast times of the GPS signals and reception times of the GPS signals, the method comprising:
- capturing the visual content during a capture duration, the captured visual content contained within video frames, the video frames including an initial video frame containing the visual content captured at a beginning moment in the capture duration, a later video frame containing the visual content captured at a later moment in the capture duration, the later moment subsequent to the beginning moment, and intermediate video frames containing the visual content captured between the beginning moment and the later moment in the capture duration;
- determining times for the initial video frame and the intermediate video frames based on the GPS time of the image capture device for the later video frame;
- and
- associating the determined times for the initial video frame and the intermediate video frames with the initial video frame and the intermediate video frames.
