Multi-stage trigger for capturing video images

摘要

Mechanisms are described for capturing video images using a multi-stage trigger button, where the effect of the trigger button is dependent on how a user interacts with the trigger button, such as during what timeframe the user releases the trigger button. For example, if the user ceases actuating the trigger button during a first time period following actuation, the capture of the video image is halted. If the user ceases actuating the trigger button during a second time period, the capture of the video image is continued. If the user ceases actuating the trigger button during a third time period, the capture of the video image is halted. Thus, for short actuations and long actuations, video images are only recorded while the trigger button is continued to be depressed. For video images in between, the video is continued to be recorded until a second actuation is received from the user.

1. A method comprising:
receiving an indication that a trigger button has been actuated; causing, with a processor, sensor data to be captured in response to actuation of the trigger button; halting the capture of the sensor data in an instance in which the actuation of the trigger button ceases during a first time period following the actuation; continuing the capture of the sensor data in an instance in which the actuation of the trigger button ceases during a second time period following the actuation; and halting the capture of the sensor data in an instance in which the actuation of the trigger button ceases during a third time period following the actuation, wherein the first, second and third time periods are mutually exclusive.
