摘要：
In a regulation of a total image quality for an encoded picture, parameter conversion data which define applicable coding bit rates and coding frame rates for each image format are previously stored in a storage 13. An image quality regulating parameter is input through a parameter input section 11 and is used as a key in an image quality regulator 12 to make a reference to the parameter conversion data in the storage 13 in order to determine a coding frame rate and an image format. By delivering the coding frame rate and the image format to picture encoding means, a regulation of a total image quality is achieved through a single operation without independently operating two parameters, the image format and the frame rate.
