Title: Circuit for detecting movement of video signal
Inventor: KONDOU TETSUJIROU
IPC: H04N5/262
Filed: 1983-12-16
Abstract: PURPOSE:To remove erroneous detection by considering an anchor bird and a background as an animated picture element by extracting a background picture from an input video signal and detecting an animated picture on the basis of the background signal. CONSTITUTION:A background picture is stored in a background memory 6, and the difference between the current picture element and an absolute value of the background picture element is detected by a subtraction circuit 9 and an absolute value conversion circuit 15. If the value is below a threshold value, the current picture element is decided to belong to the background picture, and weighting coefficient alpha is fixed to 2<-4>. An output of the substraction circuit 9 is multiplied by the coefficient alpha, added to an output of the background picture memory 6, and written in the memory 6, thereby renewing the background picture element. The coefficient alpha at this time is written in a weighting coefficient memory 7. If the absolute value of the difference is over the threshold value, an absolute value of the difference between a picture element of the previous frame and the current picture element, which is detected by a substraction circuit 8 and an absolute value conversion circuit 11, is compared with the threshold value. If an output of a comparator circuit 12 is below the threshold value, the current background is switched. When it is over the threshold value, the current picture element is decided to be an animated picture element; therefore renewal of the background memory 6 is not carried out.

SOLUTION: During operation of an engine, it is decided by an electronic control circuit 30 whether a cooling water temperature by a water temperature sensor 38 exceeds a warming-up control lower limit temperature. In a case of YES, it is then decided whether engine starting is completed. When starting is completed, it is decided by a lapse time after starting counter whether a lapse time after starting attains a first prescribed time. When the decision result is NO, ignition delay control is executed by an ignition circuit 22 and the increase of the temperature of a three-dimensional catalyst 27 is promoted. At a point of time when the lapse time after starting attains the first prescribed time, ignition delay control is completed.  It is decided whether the lapse time after starting attains a second prescribed time and in a case of NO, injection dither control is executed and a catalyst temperature is further increased through correction of the increase or the decrease of a fuel injection amount.
