Abstract
A method of determining a quantization parameter includes determining an adjustment range of a quantization parameter correction value based on a size of a motion area of an input image, calculating an average bitrate value of the input image, and adjusting the quantization parameter correction value by decreasing the quantization parameter correction value within the adjustment range in response to determining that the average bitrate value is greater than an upper limit value, and by increasing the quantization parameter correction value within the adjustment range in response to determining that the average bitrate value is equal to or less than a lower limit value.
