Abstract
An image data encoding apparatus encodes image data at a high speed while minimizing the deterioration of the image quality on a reproduced screen. The apparatus includes an encoding circuit, a code quantity counter and a control circuit. The control circuit compares a total code quantity with a reference code quantity. When the total code quantity exceeds the reference code quantity, the control circuit further compares an excessive quantity with a brought forward code quantity. The control circuit instructs an interruption of generation of the code image data by the encoding circuit when the excessive quantity is larger than the brought forward code quantity.
