摘要： Correlation of videos between fields is determined between a difference between an input interlaced signal and a signal that is delayed by one field with respect to the input interlaced signal. Correlation among N-1 sequential fields is compared with a predetermined pattern to determine whether the input interlaced signal is unquestionably a telecine-converted signal, whether it is unquestionably not a telecine-converted signal, or whether it cannot be said to be unquestionably a telecine-converted signal. If a determination of being unquestionably a telecine-converted signal is continued for a predetermined number or more of fields, an instruction signal, which instructs to perform inter-field interpolation on the input interlaced signal, is outputted.

摘要： A video theater system includes a video cassette recording at least a component video signal to which a copy preventive scheme has been applied; a video cassette recorder for reproducing the video cassette; a tuner and an antenna for receiving a signal transmitted via a satellite; a controller device for controlling the video cassette recorder and the tuner; means for releasing the copy preventive scheme; and a projector for projecting a video image from which the copy preventive scheme has been released. The copy preventive scheme is applied, while at least a synchronizing signal is retained, to a protected video signal at a point between dubbing of the master tape to the distribution tape after a video conversion and the second video cassette recorder. This copy preventive scheme is released by means of a device and circuit following a video cassette recorder used to reproduce the video signal in readiness for the projection thereof onto a screen.

摘要： A method of manufacturing optical elements which is capable of obtaining optical elements at high accuracy by molding through employment of an optical element molding glass material preliminarily processed to prevent such defects as crack formation or chipping at the corner portions of the molding material which contact dies when the material is charged into the mold. An optical element molding glass material to be employed for the above method is formed with curvatures at boundary portions i.e. corner portions where its cylindrical portion contacts at right angles with its end flat portions by applying chemical etching, heat of a carbon dioxide gas laser or radiation heat to such corner portions. Meanwhile, in the manufacturing process of the optical element in which upper and lower dies and the preliminarily processed molding material are subjected to molding through heating and pressurization in a contacted state at all times, the molding pressure is arranged to be reduced at least one or reduced to zero to provide the optical element at high accuracy.
