A Storage Arithmetic of Video Image Based on Queue Buffer Structure
基于队列式缓存结构的视频图像存储算法

Aimed at the ubiquitous problem of losing frame in th e course of video image real-time storing,the typical storage arithmetic has be en analyzed thoroughly in this paper.Then,the cause of losing video image in the process of real-time storing was found.When the same size files were saved con tinuously to the disk of the computer,the storage rate was fluctuant in stated r ange.Through adopting the queue buffer structure,the influence of the storage ra te fluctuating was avoided effectively;consequently the real-time storage of hi gh-speed video image was ensured in the condition that the rate of data flow is less than the mean rate of storage.Finally the problem of losing frame was solv ed.By experiment,the feasibility and reliability of the arithmetic was proved.
