Title: Scanning line interpolation circuit
Inventor: ITO HIROSHI
IPC: H04N3/16
Filed: 1991-02-06
Abstract: PURPOSE:To prevent deterioration in picture quality by allowing a vertical edge detection means to take precedence over an output of a movement detection means when a vertical edge is detected in a picture so as to switching a characteristic of a time space filter to the characteristic of a vertical filter side. CONSTITUTION:A movement quantity arithmetic circuit 5 calculates a movement betafrom an inter-frame difference alpha. Let a pitch of stripes be  , when the moving speed reaches  /frame, the current stripe pattern and the stripe pattern of one preceding frame are matched and the difference alpha reaches 0. In this case, when the quantity beta is outputted as it is, time base processing is implemented and remarkable deterioration in the picture quality is caused. Since correlation of the picture in the vertical direction is strong in general, a vertical filter is used independently of the movement to calculate the interpolation scanning line in the vertical edge as above. A vertical edge detection circuit 9 detects the vertical edge from the picture and when it is detected, the output of a switch circuit 10 is switched to a maximum valve betamax of the movement beta. Thus, only the vertical axis is processed independently of the movement in the characteristic of the filter in the vertical edge.

CONSTITUTION:The scraping blade 12 is provided in contact with a photosensitive body 2 in the counter direction to it between the cleaning foam roller 7 and the cleaning blade 3 so as to exist on the downstream side of the cleaning foam roller 7. Untransferred toner 4 sent from the cleaning foam roller 7 deposits in a region B between the scraping blade 12 and the photosensitive body 2 in such a case, but the scraping blade 12 is thinner than the cleaning blade 3 and, therefore, the untransferred toner 4 is moved up from the front end of the scraping blade 12 in the upward direction along the surface of the scraping blade 12 by the rotating power of the photosensitive body 2 and the pressing force of the untransferred toners 4 successively sent thereto. The untransferred toner 4 is diluted by a developer sent via a diffusion plate 6 and is recovered via the cleaning foam roller 7 and a wringer roller 10.

IPC: H04N5/18
Filed: 1991-02-06
Abstract: PURPOSE:To stabilize the black level of a video signal especially at the reception of a mixture signal of the video signal and a synchronous signal with respect to the pedestal clamping circuit in the video amplifier circuit of a display device. CONSTITUTION:A clamping pulse erasuring circuit 11 operated by a horizontal vertical mixture synchronizing signal without a delay time in comparison with an input signal is provided on a horizontal period clamping pulse fed to a clamping transistor(TR) 5 in a video amplifier circuit 1 to erase the clamping pulse for only the vertical synchronizing signal period.

Moreover, since the black level of the video signal is stabilized, even when a delay time is caused to the vertical synchronizing signal outputted from a horizontal vertical synchronizing separator circuit 8, no problem is caused and then the synchronization separating performance is set optionally.
