Interface for communicating a threshold in a camera

An electronic device comprising:

• a camera system configured to capture images of a scene;
• a camera application comprising first computer-readable instructions stored on computer-readable media and executable by one or more processors to operate the camera system in multiple modes, the multiple modes including a real-time display mode and a buffer-display mode;
• a camera buffer configured to record the images in frames during the real-time display mode;
• and
• a gesture recognition module comprising second computer-readable instructions stored on the computer-readable media and executable by the one or more processors to:
• recognize a drag gesture during the real-time display mode;
• dynamically alter a virtual shutter control according to a relationship between a drag distance of the drag gesture and a target distance threshold;
• and
• responsive to the drag distance being greater than the target distance threshold, trigger the camera application to switch modes from the real-time display mode to the buffer-display mode.

One or more non-transitory computer readable storage media comprising instructions that, responsive to execution by a processor, cause operations to be performed compromising:

• executing a real-time display mode of a camera application of an electronic device;
• displaying real-time images of a scene in a field of view of an image sensor of the electronic device during the real-time display mode;
• recording the real-time images to a plurality of frames of a camera buffer;
• recognizing a drag gesture, the drag gesture comprising a sustained one or more touch inputs that are across at least a portion of a user interface of the electronic device;
• determining a relationship between a drag distance of the drag gesture and a target distance threshold;
• dynamically altering a virtual shutter control according to the determined relationship between the drag distance of the drag gesture and the target distance threshold to visually convey the relationship to a user of the electronic device;
• and
• responsive to a determination that the drag distance is equal to or greater than the target distance threshold and that one or more of the touch inputs are removed from the user interface, triggering the camera application to switch modes from the real-time display mode to a buffer-display mode, the buffer-display mode configured to provide access to view the plurality of frames recorded in the camera buffer.
