LED SYNCHRONIZATION FOR VIRTUAL AND AUGMENTED REALITY DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18153026 titled 'LED SYNCHRONIZATION FOR VIRTUAL AND AUGMENTED REALITY DEVICES
Simplified Explanation
The patent application describes a method for synchronizing an image capture device and a light emission device using a master clock signal. Here are the key points:
- The master clock signal is divided to generate a high frequency clock signal.
- A frame timer measures the frame time of the image capture device based on cycles of the high frequency clock signal.
- An exposure timing signal from the image capture device is used to estimate the exposure start time.
- The light emission device emits a positional tracking pattern at the estimated starting time and for a duration determined by the measured frame time of the image capture device.
Potential applications of this technology:
- Photography and videography: The synchronization between the image capture device and the light emission device can improve the quality and accuracy of captured images and videos.
- Motion tracking: The positional tracking pattern emitted by the light emission device can be used for tracking the movement of objects or subjects in real-time.
Problems solved by this technology:
- Timing synchronization: The method ensures that the image capture device and the light emission device are perfectly synchronized, eliminating any timing discrepancies.
- Exposure accuracy: By estimating the exposure start time based on the exposure timing signal, the method helps in achieving accurate exposure settings for the image capture device.
Benefits of this technology:
- Improved image quality: The synchronization between the image capture device and the light emission device helps in capturing sharper and more accurately exposed images.
- Real-time tracking: The emitted positional tracking pattern allows for real-time tracking of objects or subjects, enabling applications such as augmented reality or motion capture.
Original Abstract Submitted
A master clock signal for an image capture device and a light emission device is accessed. The master clock signal is divided to generate a high frequency clock signal. A frame timer is used to measure a frame time of the image capture device based on cycles of the high frequency clock signal. Based on an exposure timing signal from the image capture device, estimating an exposure start time for the image capture device; is estimated. Based on the estimated starting time, the light emission device begins emission of a positional tracking pattern at the estimated starting time and for a duration determined by the measured frame time of the image capture device.
