Abstract: PURPOSE:To select a quantization width suitable for a line rate by controlling quantizing width of a quantizer not only from information of preceding coding but also information quantity generated in a preceding block. CONSTITUTION:A digital picture data is inputted from a terminal 31 and a prediction value outputted from a frame memory 43 is subtracted by a subtractor 32 and a prediction error being a difference is inputted to an orthogonal transmission circuit 33 and a quantization circuit 34, and a coding circuit 37, in which the data is coded and the relation among a code quantity INF, a quantization value Q and its coefficient B is given by equation (I). A coefficient calculation circuit 36 uses the coefficient B of a block of a preceding same location and a quantization width calculation circuit 35 calculates the quantization width Q giving a generated code quantity INF in matching with the line speed. The transformation coefficient quantized by the circuit 34 is restored into a transformation coefficient by an inverse quantization circuit 40 and inputted to an inverse orthogonal transformation circuit 41, in which the coefficient is restored to the prediction error. An output of an adder 42 is fed to a frame memory 43, in which the data is used for detecting a prediction value of a succeeding frame and a moving vector. The moving vector is detected from the output of the memory 43 and the input from the terminal 31.

Abstract: PURPOSE:To detect the inattentive driving, the asleep driving, etc., with higher propriety by setting variably the grant time in accordance with the change of the driver's face angle to the direction to be set during the driving. CONSTITUTION:A moving direction detecting means 1 detects the direction of a driver's face, and an angle detecting means 2 detects an angle set between the direction detected by the means 1 and the reference direction where the driver's face should be turned during the driving. Then a grant time setting means 3 sets variably the grant time based on the detected angle. In such a constitution, the inattentive driving grant time is shortened as the face turning angle increases. Therefore an alarm is produced in a comparatively short time in an inattentive driving state where the face turning angle is large and the degree of danger is comparatively high. As a result, an accurate action is attained in accordance with the driving state of the driver.
