Abstract
When real-time recording a dynamic image in a storage medium of a fixed recording capacity at a variable bit rate, an encoding generated information quantity controller obtains a recording capacity and a recording time of information to be sequentially recorded in the storage medium, obtains a remaining recording capacity and a remaining recording time of the storage medium from the obtained recording capacity and recording time, calculates a target bit rate at and after the current time from the remaining recording capacity and the remaining recording time, and controls the variable bit rate to sequentially change its quantization step size to a quantization step size for maintaining a bit rate not larger than the target bit rate. Therefore, a dynamic image data with a proper picture quality can be stored within a prescribed time and prescribed capacity of the storage medium.
