Title: Method and device for detecting moving body
Inventor: MATSUMOTO HIDEYUKI
IPC: H04N7/18
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To exactly and speedily detect with improved robustness a moving body by requantizing a first frame on the time base by performing contrast correction to it, and requantizing remaining frames using the obtained contrast corrected information. SOLUTION: The first frame on the time base is requantized by applying contrast correction and the remaining frames in an input frame group are requantized using the contrast corrected information provided by the first frame. Namely, by a frame memory 20, the density value of an inputted signal is converted to an electric charge by a positive logic and by an inverter circuit 21, the density value of an inputted signal is converted to an electric charge by a negative logic. Then, they are sent to a synthesizer circuit 22 and both are compared. By this synthesizer circuit 22, the pixels of the same luminance are mutually canceled by both. Relating to an output signal, the density of stationary section is made uniform and the pixels, which are regarded as moving bodies having different levels of luminance between both, are extracted.

Abstract: PURPOSE:To improve the reliability of lead frame soldering without sticking a liquid resin to the part upper than a stand-off by pumping up the liquid resin, ejecting the liquid resin from a nozzle and coating the resin to the rear surface of a hybrid integrated circuit. CONSTITUTION:The ejection port of the nozzle 1 is provided toward the aperture of a tank 4 and a circuit board 7 is inclined with a lead frame 6 side faced upward. The liquid resin 5 passes a pipe 3 and is ejected from the nozzle 1 when the pump 2 is operated after the circuit board 7 is brought to the under side of the nozzle 1. The ejected resin sticks to the circuit board 7 on the rear side of the hybrid integrated circuit and electronic parts 8 on the rear side. The coating on the rear side surface of the circuit board 7 is executed by the gradual movement of the resin from above to below, by which the liquid resin 5 is coated on the rear surface and the packaged electronic parts 8. The coating is thus executed without sticking the resin to the part upper than the stand-off 9 by previously adjusting the rate of the ejection from the nozzle 1 and the viscosity of the liquid resin.
