摘要： An image processing apparatus in which an image signal is divided into blocks each comprising a plurality of pixels and a quantization and a variable length encoding are executed so that a code amount of a plurality of blocks lies within a certain range. As a plurality of blocks, the position of the block which is selected at the nth order approaches the periphery of a picture screen with an increase in value of (n).

摘要： 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.

摘要： An apparatus for reproducing digital information from a recording medium having a plurality of parallel tracks and digital information recorded thereon as n-channel (n being an integer greater than or equal to 2) digital signals. The n-channel digital signals are reproduced by n-reproducing heads. The digital information contained in the reproduced signals is stored in a storage device. Discriminating data is obtained for determining which of the n-channel digital signals reproduced correspond to the reproducing heads. The timing of an access device, accessing the storage device for performing a predetermined processing of the digital signals stored in the storage device relative to the reproducing timing of the digital information reproduced by the n reproducing heads, is controlled in accordance with the discrimination data.
