Title: Motion detection method
Inventor: MIYAMOTO YOSHIHIRO
IPC: H04N19/56
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To detect the macroscopic motion of a specific object in an image or an entire image with small arithmetic capability and high accuracy by calculating a motion parameter characterizing the motion of the area of an object based on the change in a macroscopic characteristic amount between a current image frame and a reference image frame. SOLUTION: Object areas R1, R2 are extracted from a moving image. The macroscopic characteristic amount of an extracted area is detected respectively. As the macroscopic characteristic amount of each area, the gravity center position of the area Gi=(Xg1,Ygi), a tilt θi of a major axis of the area, and a size (picture element number) Si of the area are obtained. A change (E, F) in the gravity center position of the area Gi=(Xg1,Ygi) is a motion vector denoting a parallel displacement as the entire area. A change Q in the tilt θi of the major axis indicates a rotation angle of the entire area. Furthermore, a root A of a rate of change in the picture element number Si of the area denotes a magnification reduction rate of the size of the area. The detected changes (Z, Q, E, F) are outputted as motion parameters of the area.

Title: Power-supply monitoring apparatus
Inventor: CHIBA TOMIO
IPC: G01R31/00
Filed: 1999-12-13
Abstract: PROBLEM TO BE SOLVED: To estimate the failure period of a DC power supply in advance. SOLUTION: A ripple component, which is contained in the output voltage of a DC power supply 10 containing a power-supply capacitor, is extracted by an analog bandpass filter 14. The effective value of the ripple component is detected by an analog effective value detector 16. The signal of the detected effective value is converted into a digital signal by an analog/digital converter 22 to be stored in a buffer memory 24. A microcomputer 28 finds the change rate of the effective value, on the basis of the effective value of the ripple component stored in the buffer memory 24.  According to the detected effective value, the change rate of the effective value, and an ambient temperature to be measured by a temperature converter 38, inclination factor in an approximation expression, in which the effective value of the ripple component is approximated by the product of the inclination factor multiplied by time, is found. Based on the calculated inclination factor and the effective value, the failure period of the DC power supply whose output voltage becomes an abnormal level is predicted.
