A Method and System to Adjust the Camera Frame Rate Based on the Remaining Memory Capacity

A method to adjust a camera frame rate based on a remaining memory capacity, comprising:

• presetting a plurality of frame rates for adjusting the camera frame rate and a plurality of remaining memory capacity scopes for determining a scope of the remaining memory capacity;
• set corresponding relations between said plurality of remaining memory capacity scopes and said plurality of frame rates;
• and preset an upper limit and the a lower limit for the remaining memory capacity;
• detecting a current remaining memory capacity, and determine a remaining memory capacity scope in which the current remaining memory capacity belongs;
• and
• according to the remaining memory capacity scope in which said remaining memory capacity belongs, finding a preset frame rate from the preset plurality of frame rates corresponding to said remaining memory capacity scope, and adjust the camera frame rate to the preset frame rate corresponding to said remaining memory capacity;
• updating thresholds corresponding to said remaining memory capacity scope to the upper limit and the lower limit for detecting the remaining memory capacity.
