An image processing device includes: a holder configured to hold a reference picture necessary for decoding of an access unit as a processing subject in decoding of a stream composed of access units including a header; an analyzer configured to analyze the stream to thereby detect the header for each of the access units; and a generator configured to, if a header indicating change of deletion order of pictures is detected as the header detected by the analyzer, delete a picture included in an access unit corresponding to the header in the deletion order indicated by the header and generate hold information indicating a reference picture to be held by the holder.

In an encoding apparatus for processing a video signal with a signal processing circuit, producing coefficient data by an orthogonal transform of differential data obtained by motion compensation, generating coded data by quantization of the coefficient data and converting the quantization step size at the time of the quantization according to the amount of generated data of the coded data, the signal processing circuit includes: a motion vector detecting circuit for detecting a motion vector of the video signal; a motion code vector amount detecting circuit for calculating the code amount of the motion vector on the basis of the motion vector and for detecting the amount of code of the coefficient data; and a pixel number converting circuit for converting the number of pixels of the video signal according to the amount of code of the motion vector and the amount of code of the coefficient data.

Encoding apparatus and encoding method

A line number LN is extracted from serial data corresponding to BTA S-004 standard. The line number LN is placed as LN and LN to each of a luminance signal Y and color difference signals Pr/Pb of a 4:2:2 signal. The 4:2:2 signal is converted into a 3:1:1 signal by a bandwidth-compressing means. In addition, the 3:1:1 signal is re-arranged to two-channel signals Ch and Ch with the same format at a transmission rate of 46.40625 MHz. Thereafter, the, signals are processed at the transmission rate of 46.40625. The line number LN is placed as LN and LN at the beginning of one horizontal interval.

A picture enhancing circuit for a reproduced picture signal includes a field memory and a circuit for writing data into the memory, in which the reproduced picture signal is in the form of sync blocks made up of sync data and picture data. After sync detection is performed, the content of the sync data is reset to zero and written into the memory along with the picture data, and each time the sync data and picture data are read out from the field memory the content of the sync data is updated. The contents of the sync data indicate the number of times that the picture data has been read out from the memory and, thus, its age. This age is used to determine whether the picture data can be used or whether it should be interpolated before use.
