Abstract
A construction circuit which constructs data of nondecodable blocks by using interpolation data generated by a predetermined method, a movement estimation circuit which estimates the movement of the nondecodable blocks on the basis of the movement of the blocks surrounding the nondecodable block, and an error pattern detecting circuit which detects an error state of the surrounding blocks and controls the movement estimation circuit on the basis of the error state, are provided. The construction circuit constructs nondecodable data on the basis of the result of the estimation by the movement estimation circuit. An image reproducing apparatus is provided which is capable of obtaining a reproduced image having reduced visual deterioration by estimating movement on the basis of the blocks surrounding the nondecodable block when the data of the nondecodable block is reproduced and detecting the error state of the adjacent blocks.
