A positioning apparatus calculates an offset frequency of a local oscillator based on position information which is positioned, satellite position information acquired from a satellite signal of a GPS satellite, and a velocity vector of a GPS satellite. A GLONASS function is operated based on the offset frequency; then, positioning is carried out by the GPS function and the GLONASS function.

A correlation evaluation unit evaluates a correction between a predetermined region in a targeted picture and a region corresponding to the region in a picture differing from the targeted picture in a temporal direction. A quantization control unit adaptively controls quantization processing for the predetermined region in the targeted picture, according to an evaluation obtained by the correlation evaluation unit. For example, when it is determined by an evaluation value obtained by the correlation evaluation unit that the correlation is weaker than a predetermined threshold value, the quantization control unit enlarges a quantization step used for quantization of the predetermined region.

A frame memory holds a reference frame that is to be referenced for motion detection for a target block of a coding target frame in motion images. A motion compensation unit that includes a motion detecting unit and a motion compensated prediction unit. The motion detecting unit detects the motion of said target block by repeated motion estimation with reference to said reference frame stored in said frame memory, and the motion compensated prediction unit performs motion compensation processing for the target block using information on the detected motion. A coding unit that performs coding processing for the subtraction image and the information on the detected motion and thereby creates a coded stream. The motion compensation unit includes a pre-reading memory which stores pixel data beforehand, where said pixel data is part of pixel data in said reference frame, which is to be frequently referenced for motion detection, and which has been transmitted from said frame memory.
