Title: Transmitter and receiver for video signal
Inventor: AKIYAMA TOSHIYUKI
IPC: H04N7/015
Filed: 1990-11-02
Abstract: PURPOSE:To obtain a video signal with excellent picture quality without causing grating like distortion at a border of blocks by selecting a video signal of a best field from each area having almost the same shift quantity among video signals, transmitting the selected video signal, correcting the shift quantity and demodulating the signal thereafter. CONSTITUTION:Video signals of each field inputted to a transmitter are divided into plural areas in which the shift quantity is almost the same. Then a field optimum for the transmission in each divided field of each area is selected and a data relating to a video signal of the sent field is added to the field and the result is sent. Moreover, a receiver receiving the transmission signal stores sequentially sent video signals of each field. After the shift quantity is corrected to the video signal of each field stored based on the shift quantity of each area to be sent simultaneously, the result is synthesized and the result is outputted as a demodulation signal. As a result, an excellent demodulation video signal without causing grating stripe is obtained without much increase in the transmission information quantity.

Abstract: PURPOSE:To enable uniform inspection while achieving a reduction in labor by detecting how a conductive paint fills a through hole with a CCD camera from the opposite side to the side of filling to eliminate the need for visual inspection with a possible automatic inspection. CONSTITUTION:A squeegee 2 is kept running at a specified angle on a substrate 1 to make a conductive paint 3 fill a through hole 4. A detection means 6 has a CCD camera 9 so arranged on the rear of the substrate 1 to face the hole 4 which the paint 3 fills. So, a digital signal of an image of a peripheral part of the hole 4 is displayed visible on a video monitor while the diameter of the paint 3 extruded to the rear of the hole 4 is detected and the resulting detection signal is outputted to a judging means 7. The means 7 compares a data pertaining to the diameter of a land formed at the hole 4 and in the perimeter thereof stored therein with the diameter of the paint 3 inputted from the means 6 to judge the propriety of the filling. When receiving a judging signal of the poor filling level, a control means 8 increases or decreases in the angle of inclination of the squeegee 2 to correct the filling level of the paint 3.
