摘要： PURPOSE:To easily generate the inverting output with desired gain easily with a simple constitution, by constituting the output circuit of charge transfer element (CTD) with a current Miller circuit. CONSTITUTION:When the final stage transistor Qn forming CTD is conducted with the control signal phi2, the current corresponding to the signal charge stored in the capacitor Cn-1 flows to a pnp type transistor 14 in which the collector and the base are connected to the collector of transistor Qn through the formation of a current Miller circuit. Further, the inverting output with different gain is produced according to the resistor 17a... from pnp type transistors 15a, 15b... at the output side connected to resistors 17a, 17b... different in resistance through the formation of the current Miller circuit. Thus, without using differential and operational amplifiers, the inverting output with desired gain can easily be obtained with a simple constitution.

摘要： PURPOSE:To expand a dynamic range with simple constitution without changing a dielectic strength request, by forming an output circuit of complementary transistors driven at a fixed voltage, transistors with a voltage dropping method provided to a current path, capacity elements, etc. CONSTITUTION:Random capacitor C2n of a charge transfer device such as BBD is connected to the connection point between output complementary transistors 11 and 12 and transistor 11 is connected to transistor 14 with voltage dropping diode 21 provided to a current path via a connection point connected to capacitor 15. Those transistors 11 and 12 are driven by signal phi1' in phase with clock phi1 by oscillator 13, and transistor 14 is also driven by signal phi2' in phase with clock phi2 and equal in potential to signal phi1' through oscillator 20. Futher, the simple constitution increases the signal upper limit of transistor 11 and expands the output dynamic range and a voltage drop across diode 21 nearly equalizes the dielectric strength request of transistor 14 to that of BBD.

摘要： PURPOSE:To coincide the signal level and DC potential to the input signal, by outputting the signal eliminating the DC potential variation of CTD in connection with the complementary active element and current Miller circuit at the cold side of the capacitance of the charge transfer element (CTD). CONSTITUTION:The complementary transistors 11, 12 at the cold end side of the capacitor Cm of CTD constituting the delay circuit with BBD are controlled with the same clock phi2' as the clock phi2 from the oscillator 13, and the current corresponding to the signal voltage from the terminal 4 flows to the resistors 16, 18 having a given resistance ratio via the transistors 15, 17 of the current Miller circuit. Thus, the charge of the capacitor Cm is changed in response to the voltage of the clock phi2', and the current flows to the transistor Qm+1 of BBD, and the potential of the capacitor 20 with the output transistor 19 is the difference between the signal voltage and the clock voltage. At the cold end of the capacitor 20, the clock voltage is fed the output signal level and DC potential from the terminal 21 are in agreement with the input signal.

CONSTITUTION:Multiplier circuit 13 generates correction signal SPR composed of high-band signal YH and luminance signal YN with amplitude nearly equivalent to a ratio between the variation in amplitude of low-band signal YL of luminance signal YN and that in amplitude of color difference signal (R-Y)L at the time of this variation in amplitude. Then, this signal SPR is superposed upon color difference signal (R-Y)L to improve space frequency characteristics and sharpness circuit 15 improves the sharpness of luminance signal YN, which is supplied to matrix circuit 5. This circuit 5 performs a matrix process of each color difference signal to generate primary blue, red and green signals. Consequently, a blur of color is removed and a screen of excellent sharpness can be obtained.

摘要： PURPOSE:To prevent the color blotting of the demodulated chrominance signal by varying the delay amount of the carrier chrominance signal by the correction signal formed based on the high band component of the luminance signal to increase the range of the carrier chrominance signal. CONSTITUTION:Carrier chrominance signal Sc is supplied to color demodulator circuit 2 to change the low-band luminance signal to YN and the narrow-band signals of red, green and blue to RN, GN and BN respectively. In this case, color difference signal RN-YN, GN-YN and BN-YN respectively are demodulated and then supplied to matrix circuit 3 to form primary color signals R, G and B. At the same time, the correction signal corresponding to the contour part of the picture formed based on high-band component YH of the luminance signal is applied to variable delay circuit 10, and the delay amount is varied to increase the range of the carrier chrominance signal. Thus, the color blotting can be prevented for the demodulated chrominance signal.
