摘要： PURPOSE:To provide a desired resolution degree of any object to be taken by controlling a reset pulse of a charge detecting amplifier using the same optical system in an optical converter. CONSTITUTION:Camera elements 1 are arranged at every other bits through transfer gates 2 and 3 as divided between odd and even analog shift register systems 4 and 5. Output signals from the output register are fed to a charge detecting diode, and the potential generated in response to the amount of the signal charge thus generated is amplified by a charge detecting amplifier 7 and produced as an output. A reset pulse is applied to the amplifier 7 to alter the resolution by controlling the period of the pulse.

摘要： PURPOSE:To establish the circuit simple and less in power consumption and error, by making equal the conduction time of the sampling circuit every data line for the matrix type video display to the time distance of video sampling point assigned to the video signal. CONSTITUTION:The shift register 19 of the data sampling circuit of the matrix type video display unit is constituted with one stage of delay FF to each data line. In this case, the pulse width of the input timing data 23 is in agreement with the one period of the clock signal 22 determining the sampling points a,b,c... of the video signal 15 or a multiple so that the output is made to the terminals 27, 28, 29... The data sampling pulse 24 or 25 from the terminals 27, 28... keeps the ON time of the gate 30 so that they are all equal to the sampling period or a multiple. Thus, the leading and trailing of each pulse are contacted with the leading and trailing before and after to obtain sampling circuit less in error.

摘要： PURPOSE:To obtain the excellent picture quality by averaging the information value having the plural adjacent picture elements feature and then displaying the averaged value in the form of one picture element. CONSTITUTION:The video signal drawn out at video detection circuit 401 undergoes the A/D conversion through A/D converter 404 and is then memorized temporarily in auxiliary memory circuit 403. And the contents is memorized in main memory circuit 406 within the blanking time of each scan line. Then the adjacent information of the necessary number in the vertical, horizontal and oblique directions of each picture element are read out and then averaged through process circuit 414 in a digital way. The averaged signal undergoes the D/A conversion through D/A converter 409 to be returned to the original video signal. And row driver 410 scans each row in sequence. Then the lines are also scanned sequentially via line driver 411 and based on the reading velocity. For each picture element thus driven, the peripheral information to be sampled are also averaged to be displayed. Thus, the high-quality picture can be obtained even with a small number of picture elements.

摘要： PURPOSE:To increase the resolution of the TV video signals by defining the NH of even-number times as much as the H period of the original TV video signal as one horizontal display period and then applying the coding signals of one horizontal period obtained through sampling every NH/M to each picture element. CONSTITUTION:Gated oscillator circuit f1 is triggered by the inverse output of preset pulse P1 to have oscillation with frequency f1. While gated oscillator circuit f2 is triggered by the output of NAND circuit N1 to have oscillation with frequency f2. And binary counter CT2 delivers the output to circuit N1 after counting the pulse of frequency f1 by the fixed times. Thus, the output corresponding to frequency f1 and f2 applied to AND circuit A1 and A2 via FF2 is obtained through the OR circuit. Here, the NH of even-number times as much as the H period of the original TV video signal is defined a one horizontal display period, and the coding signals of one horizontal period obtained through sampling every HN/M are applied to each picture element signl for display. Thus, the resolution of the TV video signals can be increased.

摘要： PURPOSE:To give the zoom effect and to perform the display with high resolution, by displaying the entire or a part of the original picture with sampling, in the unit in which the number of the light emitting elements constituting the video elements is less than the number of the video elements constituting the original video signal. CONSTITUTION:In the display unit in which the number of the light emitting elements constituting the matrix panel MP is less than the number of video elements of the original video signal, the timing of the sampling pulse Sc of the clock pulse generating circuit Sc fed to the sampling hold circuit SPH of the AD conversion circuit AD is controlled to set the leading edge of the horizontal direction display by the panel MP of picture specified with the original picture. Moreover, the preset pulse of the horizonal synchronous signal counter H for shift pulse generation of vertical scanning signal is formed. The display leading edge of the panel MP is set by delaying the delay amount of the vertical synchronizing signal separated with the synchronous separation SYS from the original video signal with the scan pulse generating circuit SG.

摘要： PURPOSE:To attain channel switching display and other display easily, by making alternations between some of picture signals and other display signals or by making use of a selection period for scanning signals. CONSTITUTION:Between the odd field and even field of an effective picture signal used for picture display, there is an ineffective interval of 42H per frame. Here, 1H is an interval for one-field scanning and equivalent to 1/525 sec. In case of a liquid crystal television, each scanning selection interval is several Hs. When each scanning selection interval is supposed to be NH, a 42/n number of scanning lines are left. This scanning has no relation with television picture display, so that other display signals (channel selective display signal in this case) will be sent out from a signal electrode during this interval.
