IPC: H04N19/59
Filed: 1986-07-17
Abstract: PURPOSE:To reduce the unnaturalness in a switching picture by a dither effect by alternately performing the selection operation of a selector for selecting a moving picture signal and a still picture signal at high speed when the output of a moving signal detection circuit indicates a switching time from a moving picture to a still picture. CONSTITUTION:At the switching part of the still picture and the moving picture, since also the output of a latch circuit 50 goes to a high level according to the output of a NOR circuit 49, a switch 51 is turned on. Consequently, noise from a pseudo noise generating circuit 52 is inputted to an adder 53 and added to the moving signal M passing through latch circuits 42, 43. Accordingly, the output B8 of a comparator 54 repeats a high level and a low level at high speed at the switching part of the still picture and the moving picture. When a control signal goes to the high level, a moving picture adaptation processed signal is selected and when it goes to the low level, a still picture adaptation processed signal is selected. Therefore, the unnaturalness at the switching part on the picture becomes inconspicuous.

Abstract: PURPOSE:To compose one memory cell of one transistor (TR) and to enable electric erasure by providing the floating gate of a double gate type MOSTR with an erasure gate in parallel. CONSTITUTION:When data is to be written in a memory cell M1, a positive high voltage is applied to a selection line 35 and a digit line 31 respectively to cause thermoelectrons to flow from the source S of the cell M1 to the drain D, and the thermoelectrons are applied from a channel area to a floating gate FG. Consequently, the threshold voltage VTH of the cell M1 rises. For readout, the line 35 is selected and a high-level signal is applied to the control gate CG of the cell M1. In this case, when the voltage VTH falls, the cell M1 turns on and when rising, it turns off. For erasure, the lines 35 and 31 are held at 0V and a high voltage is applied to an erasure line 33; and then, electric field emission is caused between the gate FG and erasure gate EG of the cell M1 to flow accumulated electrons out of the gate FG, so that the voltage VTH is returned to the initial value.
