Claim:
1. A method for storing a video image, comprising: for each frame of image collected, generating a confidence value after passing M frames of image each time, wherein M is a positive integer; after passing N frames of image each time, determining a target encoding frame rate based on the confidence value latest generated and a mapping relationship curve between the confidence value and the target encoding frame rate, encoding and recording the N frames of image based on the target encoding frame rate determined, wherein N is a positive integer; wherein the mapping relationship curve is a monotonic non-declined curve, the confidence value is a rational number located in [Tmin, Tmax], Tmin>=0, a greater confidence value denotes a greater probability for a focused-on target exists in an image; wherein the target encoding frame rate is a rational number located in [Fmin, Fmax], Fmin>0; when the confidence value is Tmin, the corresponding target encoding frame rate is Fmin; and when the confidence value is Tmax, the corresponding target encoding frame rate is Fmax.
