摘要： A motion compensation predicting coding apparatus includes a motion detector for comparing pixel data in an image signal with pixel data of the previous image signal to generate a motion vector. The motion vector is indicative of the displacement differences between the image signal and the previous image signal. The image signal may be organized into blocks of pixel data for a single field or for multiple fields when notion detection is performed on the image signal by the motion detector. A subtracter generates a prediction compensation error signal by subtracting the pixel data in the previous image signal from the pixel data of the image signal. A coder receives the prediction compensation error signal and generates an appropriate coded output. The apparatus may also include an adaptive blocking mechanism for receiving the prediction compensation error signal and organizing the data in the signal into blocks into one of several fashions as dictated by the motion vector.

摘要： An image coded data re-encoding apparatus (30) which generates in an image coded data analyzer (310) coded data after signal processing (221) by performing a first digital signal processing on first image coded data (220), supplies an image coded data synthesizer (320) with the coded data after signal processing (221) and multiple signals (222) associated with the first image coded data, and generates in the image coded data synthesizer (320) a second image coded data (240) by performing on the coded data after signal processing (221) a second digital signal processing based on multiple signals (222). The second image coded data is generated without once decoding the first image coded data. This makes it possible to prevent degradation in image quality, delay involved in the transform and an increase of the device size.

摘要： An adaptive blocking coding system selects an effective blocking of an input image signal to be encoded in accordance with the correlation between fields, even if motion is detected between the fields. The blocking patterns include an individual field blocking, a non-interlace blocking, a split blocking and an inverted split blocking. Further, the coding system searches for motion from both odd and even fields of a frame for producing a motion compensated prediction signal in order to provide high-efficient coding.

摘要： A picture signal encoding and decoding apparatus which transmits a digital picture signal by encoding, and receives and decodes an incoming encoded signal comprises a configuration in which a condition not to make a receiving buffer overflow can be controlled on the transmitting side, and a plurality of quantizers are prepared and a proper quantizing characteristic is selected and used according to the sequence of transformed coefficients and the size of a motion vector. Therefore, it is not necessary to prepare a receiving buffer of a large capacity or a high speed decoding circuit, so that the apparatus can be manufactured at a low cost and the stability of operation is improved and also a signal can be compressed efficiently owing to the realization of quantization corresponding to a statistical characteristic of an input signal.

摘要： An image decoding device method for obtaining image signals by decoding compressed data of digital moving image signals in a 4:4:4 format is disclosed. An identification signal is decoded, the identification signal indicating whether three color component signals have been encoded in a common encoding mode or in independent encoding modes. The common encoding mode corresponds to a process of encoding the three color component signals of one frame by a common macroblock type information and the independent encoding mode corresponds to a process of encoding the three color component signals of one frame by an individual independent macroblock type information. The three color component signals are decoded in a common encoding mode or in independent encoding modes according to the identification signal.
