    • An image coding apparatus provides a run-length encoding unit RLE1 that subjects quantized coefficients which are obtained by quantizing frequency components of an image signal to a variable length coding process by using a run value Run that indicates the number of successive zero coefficients and a level value Lev that indicates a value of a non-zero coefficient following the zero coefficients. The run-length encoding unit RLE1 includes a reordering unit Lreodr for reordering level values Lev; a variable length coder LVLC for coding reordered level values ROLev by using a code table that is selected according to the value of a quantization parameter QP; a reordering unit Rreodr for reordering run values Run from high frequency component of the quantized coefficients to low frequency component; and a variable length coder RVLC for coding reordered run values RORun by using a code table that is selected according to the number of already-processed run values.

    • A vehicle steering control device which prevents overshoot or a phase delay of a vehicle position from a target position when an actuator of a steering mechanism is controlled so that an integral control reduces a positional deviation of a vehicle from the reference position of a traffic lane. An FB control unit (60) which calculates a corrected steering assist torque (Tb) of a motor so as to reduce a positional deviation (Yd) and an angular deviation (Ah) includes an integral element determination unit (64), which determines an integral gain (Ki), by which the positional deviation (Yd) is multiplied in an integral gain operation unit (62), according to the positional deviation (Yd) and which determines a limit value (Icnt_lmt) of an integral controlled variable (Icnt) according to the positional deviation (Yd), and an integral controlled variable limiting unit (63) which limits the integral controlled variable (Icnt) to within a range set by the limit value (Icnt_lmt) and outputs the current integral controlled variable (Icnt_rel).

    • In coding a picture to be used as a reference picture by another picture, a motion vector used in inter picture predictive coding is stored into the motion vector storage unit (116). However, the storage of a motion vector is controlled by the coding control unit (110) in such a way that motion vectors of pictures, fewer in number than the number of reference pictures, are stored into the storage unit (116). In the case where direct mode is used in coding a B-picture, if the motion vector to be referred to in coding in direct mode is stored in the motion vector storage unit (116), coding is performed using such motion vector. Further, in the case where the motion vector is not stored in the storage unit (116), coding is performed with the motion vector as “0”, and using a motion vector of a neighboring block.
    • 在将另一图像用作参考图像的图像编码时,将用于帧间预测编码的运动矢量存储到运动矢量存储单元(116)中。 然而,由编码控制单元(110)控制运动矢量的存储,使得数量少于参考图像数量的图像的运动矢量被存储到存储单元(116)中。 在对B图像进行编码时使用直接模式的情况下,如果在直接模式编码中要参照的运动矢量存储在运动矢量存储单元(116)中,则使用这样的运动矢量进行编码。 此外,在运动矢量未存储在存储部(116)的情况下,以运动矢量为“0”,并使用相邻块的运动矢量进行编码。

    • According to a picture coding method of the present invention, a coded picture identified by a picture number is stored, as a reference picture, into a storage unit; commands indicating correspondence between picture numbers and reference indices for designating reference pictures and coefficients used for generation of predictive images are generated; a reference picture being used when motion compensation is performed on a current block in a current picture to be coded is designated by a reference index; a predictive image is generated by performing linear prediction on a block being obtained by motion estimation within the designated reference picture, by use of a coefficient corresponding to the reference index; a coded image signal including a coded signal obtained by coding a prediction error being a difference between the current block in the current picture to be coded and the predictive image, the commands, the reference index and the coefficient is outputted. At that time, information indicating the maximum reference index value is coded and included into the coded image signal, and the commands indicating correspondence between at least one picture number and a plurality of reference indices are generated.
