Title: Simultaneous recording and reproducing device for multi-system signal
Inventor: TAKEDA MASARU
IPC: H04N5/91
Filed: 1993-07-23
Abstract: PURPOSE:To enable simultaneous recording and reproduction of >=3 systems by recording signals of multiple systems as a mixed video signal of one system and reproducing it by frame interpolation. CONSTITUTION:Video signals of Ch1 and Ch2 received by tuner parts 11 and 12 are mixed by a mixing part 13 and outputted as a mixed video signal (Mix) to a video device 15. The mixing part 13 generates the signal Mix by superposing frames corresponding to odd-numbered vertical synchronizing signals of Ch2 on frames corresponding t even-numbered vertical synchronizing signals of Ch1. A sound signal mixing part 14 assigns the sound signal of Ch1 as the main sound of sound multiplexing and record it as a main sound signal R from the sound input R of the device 15. The input L of the device 15 is similar. For reproduction, the signal Mix reproduced by the device 15 is passed through a video signal selection part 16 to separate the video signals of Ch1 and Ch2, which are reproduced and displayed on a display 18. Thus, the simultaneous recording and reproduction are performed.

Title: Pattern extracting device
Inventor: ABE SHIGERU
IPC: G06T7/00
Filed: 1987-08-17
Abstract: PURPOSE:To extract accurately a corner part as a corner and a curve part as a curve by using a straight line extracting device and then using a line patterning device to perform line patterning processing with straight line components kept remaining based on the extracting result of the straight line extracting device. CONSTITUTION:Image data shown in a binary form is stored in a memory 1 via a central arithmetic processing unit 2. Then the image data on a straight line part is extracted out of the binary image data via a straight line extracting device 4. The result of this extraction is stored in the memory 1 via the processing unit 2. Then the data on a long straight line part is extracted out of the data on the straight line part. This extracted data and the initial binary image data are used so that a line patterning device 5 performs line patterning processing with the straight line part kept remaining. The image data on the line pattern thus obtained is shaped. Then the image data on the line pattern thus obtained is stored in the memory 1. As a result, a corner part of a binary image is extracted as a corner without showing roundness together with a curve part extracted accurately as a curve. Thus the images of high quality can be extracted.

Filed: 1988-08-16
Abstract: PURPOSE:To change a capacitance by a method wherein taps are formed at least on both ends of an auxiliary winding and contacts to which current-limiting resistances connected to the taps of the auxiliary winding formed between both taps have been connected are changed over one after another in order to prevent an arc from being generated. CONSTITUTION:When a changeover piece 15 comes into contact with a contact 12 before it leaves a contact 11, a current-limiting resistance 8 is connected to the changeover piece 15; accordingly, an arc is not generated. In succession, when the changeover piece 15 is connected across contacts 12, 13, a voltage between both ends of an auxiliary winding 2 is short-circuited by the changeover piece 5; however, a short-circuit current is suppressed by current-limiting resistances 8, 9. In addition, when the changeover piece 15 is connected across contacts 13, 14, the current-limiting resistance 9 is connected to the changeover piece 15; accordingly, even when the changeover piece 15 leaves the contact 12, the arc is not generated. When the changeover piece 15 comes into contact with only the contact 14, the changeover piece 15 is connected directly to a tap 7, and the auxiliary winding 2 is separated from a main winding 1. The arc is not generated even when the contacts are changed over at this moment.

Filed: 1987-08-17
Abstract: PURPOSE:To reduce the interference of noise in a video signal period and to track a target with high accuracy by putting generated noise of a switching power source in blanking periods of the horizontal synchronizing signal of an image pickup device. CONSTITUTION:A synchronizing circuit 18 receives the horizontal synchronizing signal from the image pickup device and actuates a driving circuit 12 to turn on and off a transistor TR11 while actuating an exciting energy absorbing circuit 20 through a gate circuit 19. At this time, when the charging voltage of a capacitor C15 exceeds a specific value, the circuit 20 is actuated through the circuit 19. Then the TR22 in the circuit 20 is turned on to supply a current from a DC power source 21 through the winding n3 of a transformer 17 and at the same time, the charged energy of the transformer 17 is regenerated on an input side. Then an absorbing circuit 20 operates in blanking periods of the horizontal synchronizing signal to regenerate the energy remaining in the transformer 17 on the power source input side. Consequently, the current of the winding n3 becomes zero in the blanking periods of the horizontal synchronizing signal and the generation of noise is put in the blanking periods.
