    • A rate control method used in encoding images is provided, including setting initial values for rate control and encoding; calculating a target encoding bit value based on the set initial values; performing rate control and encoding of a current bit stream based on the calculated target encoding bit value; measuring the picture quality of the current encoded bit stream, determining whether or not to skip the current encoded bit stream based on the measured picture quality, and generating a current encoded bit stream skip control signal; and controlling skipping of the current encoded bit stream, based on the current bit stream skip control signal provided by a picture quality measuring and skip control signal generating unit. In the method, a bit rate is controlled by considering the picture quality of an encoded bit stream such that a constant bit rate and appropriate picture quality can be maintained simultaneously.
    • 提供了一种用于编码图像的速率控制方法,包括设置速率控制和编码的初始值; 基于设定的初始值计算目标编码比特值; 基于所计算的目标编码比特值执行当前比特流的速率控制和编码; 测量当前编码比特流的图像质量,基于测量图像质量确定是否跳过当前编码比特流,以及生成当前编码比特流跳过控制信号; 并且基于由图像质量测量和跳过控制信号生成单元提供的当前比特流跳过控制信号来控制当前编码比特流的跳过。 在该方法中,通过考虑编码比特流的图像质量来控制比特率,使得可以同时保持恒定的比特率和适当的图像质量。
