Abstract
If a reference frame displayed at the reproduction side immediately before a current image frame to be encoded is an inter encoding image frame, a quantization control device (999) appropriately corrects the level (quantization value) of an intra encoding so as to visually reduce I-frame flicker caused by a difference between the inter encoding noise characteristic of the inter encoding image frame and the noise characteristic of the current intra encoding.
