摘要： A video coding method and apparatus realize that a calculation amount required to perform a converting process operation of compression formats can be reduced, and also deterioration in an image quality, which is caused by this compression format converting process operation, can be reduced. A video converting unit includes added information processing means for using added information contained in an input bit stream in coding operation. This added information involves a motion vector, a motion prediction difference signal, a quadrature converting coefficient, and a quantizing value.

摘要： A first data sequence generated by a first moving picture coding system having an intra-frame coding mode and an inter-frame coding mode is transformed to a second data sequence generated by a second moving picture coding system having an intra-frame coding mode and an inter-frame coding mode. The method includes prereading a coding mode of a successive frame succeeding a present frame from the first data sequence, judging whether or not a preread coding mode of the successive frame is the intra-frame coding mode and determining whether or not to code the present frame by the second moving picture coding system corresponding to a generated code amount of the second data sequence when the coding mode of the successive frame is the intra-frame coding mode. Data coded by the intra-frame coding mode existing in the first data sequence is transformed to the second data sequence.

摘要： The transformation method for moving picture coding system reads data of a frame from the first data sequence in the first moving picture moving coding system, prereads a coding mode of a successive frame to record, and when the preread coding mode of the successive frame is the intra-frame coding mode, performs a control not to perform coding of a present frame or decrease a generated code amount corresponding to the generated coed content of the second data sequence in the second moving picture coding system. Then, the method preferentially transforms data coded by the intra-frame coding mode existing in the first data sequence to the second data sequence.

摘要： For a temperature adjustment process that uses high viscosity ink and is based on a first table, in a low temperature environment, an ink refill failure may occur and lower density may appear in high duty printing. Also for a temperature adjustment process that uses high viscosity ink and is based on second and third tables, in a low temperature environment, an ink refill failure may occur and lower density may appear. On the other hand, for a temperature adjustment process that employs a fourth table, a smaller pre-heat pulse width than that for the first table, for the conventional temperature adjustment, is employed in the same low temperature environment. Therefore, an ink refill failure does not occur, and horizontal or vertical gaps do not appear during high duty printing.
