Title: Longitudinal fluctuation preventing device for image
Inventor: MITANI HIROSHI
IPC: H04N5/93
Filed: 1993-01-19
Abstract: PURPOSE:To prevent an image from longitudinally fluctuating at the time of special reproduction by delaying the composite video signal outputted from a VTR by a specific time and supplying the video signal to a monitor side. CONSTITUTION:The composite video signal is delayed nearly by an integer multiple of a horizontal synchronizing signal period Th. Namely, a reproduced video signal inputted from an input terminal 103 is delayed nearly by the horizontal synchronizing signal period Th through video signal delay means 101 and 102. Further, the delay time Td of the video signal delay means is expressed by an equation, where Ts is the period of a subcarrier and (n) and (m) are optional integers. This system generates the undelayed video signal at a point (a), the video signal which is delayed by about Th at a point (b), and a video signal which is delayed by about 2Th at a point (c). A switching means 104 selects one of the video signals at the points (a)-(c) according to an external command and outputs it as an output video signal to an output terminal 105. The external command is generated according to the relative position relation between a reproducing head and a track.

Abstract: PURPOSE:To stably control developer concentration at all times by varying the replenishing time of toner according to the size of transfer paper. CONSTITUTION:A controller 32 operates a toner feeding device 33 for a specific time according to a digital signal outputted from the output terminal P of an A/D converter 31. Namely, a difference signal (d) which varies similarly to variation in developer concentration is computed by the controller 32 and a supply table which controls the toner replenishing device 33 is so constituted that the control is performed according to the straight line of an A4 system when the size of transfer paper is A4 or the straight line of an A3 system when the size is A3. The replenishing time is different between the A4 and A3 system even with the same difference signal and the supply time of the A3 system is longer. Consequently, even if the size of the transfer paper changes, invariably stable developer concentration is held.

Abstract: PURPOSE:To stabilize the frequency characteristics of high frequency part of a video signal, by detecting the amplitude of a color burst signal of a color TV signal and controlling the amplitude to be stable. CONSTITUTION:An outut of a frequency characteristic compensation circuit 3 is applied to an ACC circuit 6 via a chroma signal band pass filter 5, and the amplitude of the burst signal is detected at the circuit 6 and an ACC control voltage is generated. Feedback is applied to the circuit 3 so as to make the amplitude of the color burst signal constant. For example, if the high frequency characteristics of a color TV composite video signal being an output of a VIF amplifier and video signal detection circuit 2 are deteriorated and the amplitude of the color burst signal is small, the ACC control voltage generated at the circuit 6 is controlled to increase the high frequency component at the circuit 3, and if the high frequency component is excessive and the amplitude of the color burst signal is too much, the control is done to suppress it. Thus, the frequency characteristics of the high frequency component of the video signal are made stable.
