Abstract
An image encoding apparatus, an image encoding method, and an image encoding program capable of minimizing image degradation, controlling a code amount in units smaller than a picture, and ensuring that encoding of the picture is completed within a certain time period is provided. A symbol number estimating device estimates the total bin number of a plurality of macro blocks constituting a picture. An entropy encoding selector outputs the entropy encoding mode selecting signal to an entropy encoder using the inputted bin number, in order to select one of a CABAC device or a VLC device. A CPU performs image encoding by executing a control program stored in a program storing portion.
