Abstract
This invention relates to an image encoding method and apparatus, and particularly has as its object to satisfactorily control the amount of encoded image data. In order to achieve this object, according to this invention, there is disclosed a technique for sequentially controlling the code amounts in accordance with accumulated code amount information and accumulated encoded area information, so that variable-length codes of an image fall within a predetermined memory capacity in a single pass. More specifically, in an image processing apparatus having a compression processor ( ) for compressing input image information, and a memory ( ) for storing encoded data by the compression processor ( ), a code amount controller ( ) calculates a reference code amount on the basis of the input image information, and controls the encoding condition of the compression processor ( ) on the basis of the calculated reference code amount.
