Filed: 1974-10-03
Abstract: 1480516 Television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 Oct 1974 [6 Oct 1973] 42932/74 Heading H4F An aperture correction circuit Fig. 1, for improving the field scan definition in a television camera comprises: a low pass filter 4 having a bandwidth of 0 to 4 MHz; a clamping circuit 5 to which a signal D incorporating clamping pulses which give a reference block level during the line blanking time of the input picture signal, is applied; one line period delay circuits 8 and 9 having a high pass bandwidth of 4 to 6 MHz producing respectively a once delayed signal G1<SP>1</SP> and a twice delayed signal G2<SP>1</SP> through signal modulation and demodulation means 6, 10 and 11, employing a carrier frequency of 6À2 MHz; signal combining circuits 15 and 16 producing an aperture correction signal LV to be applied to an adder 17 together with the once delayed signal; and a high pass filter 18 having the same bandwidth as delay circuits 8 and 9, to which the undelayed signal G is applied and the output GO of which is connected to a third input of adder 17 so that an aperture corrected signal GC occurs at an output 21 thereof. The circuit may include a line scan aperture correction signal shaper 20 comprising further delay circuits similar to 8 and 9, the additional correction signal CH being applied to a fourth input of adder 17. In a colour system the correction signal is derived from the green signal G and applied to the red R1 and blue B1 signals by adders 22 and 23. In a second embodiment, Fig. 3, components 4 to 16 supply the field scan correction signal CV to the adder 17 together with the once delayed signal M1<SP>11</SP>. The picture signal M includes field sync. and equalizing pulses, and is further applied to a pulse separator 27 the outputs of which control the clamping circuit 5 and a gating signal generator 28 which in turn controls a gating circuit 26 connected between the combining circuit 16 and adder 17 so as to block the correction signal CV during at least the field sync. and equalizing pulses, which are passed to the adder 17 in the once delayed signal M1<SP>11</SP>. The circuit is completed by a high pass filter 18<SP>1</SP>, incorporating a delay TH, connected between the undelayed signal M and the third input to adder 17. When the signal M with the broadband luminance signal and the narrow band colour difference signals modulated in quadrature on a carrier is applied to the input 1, Fig. 3, the bandwidth of low pass filter 4 may be chosen so that little or no information of the carrier modulated with the colour difference signals occurs in the signal MO<SP>1</SP>. The aperture correction signal CV is then only derived from the low frequency part of the luminance information. The filter 18 of Fig. 1 may be used instead of filter 181.

A second storage drum of the same diameter as the drawing drum may be added. The drawing drum 1 and a gear-wheel 10 are secured to a shaft 2 and freely rotatable on the shaft are a storage drum 3, a second storage drum 12 and two arms 7 and 7<SP>1</SP> each of which carries a guide roller 5, 13. The arms extend beyond the shaft and each supports a planet pinion 8, 8<SP>1</SP> and a driving pinion 9, 9<SP>1</SP>. The pinions are secured in pairs to common shafts which are freely rotatable in the arms. The driving pinions 9, 9<SP>1</SP> mesh with corresponding gear-wheels 11, 11<SP>1</SP> secured to the drum 3, and the pinion 8<SP>1 </SP>meshes with a wheel 10<SP>1</SP> secured to the drum 12. The wire 4 runs on to the drum 1, over the guide pulley 5 to the storage drum 3 and then over the guide pulley 13 to the drum 12 from which it passes to the next stage of the machine. If wire is withdrawn from the drum 12 at the same rate as it is applied to the drum 1 the carrying arms 7 and 7<SP>1</SP> do not rotate, but if wire is drawn off the drum 12 more quickly than it runs on to the drum 1 the arm 7<SP>1</SP> runs ahead of the drum and unwinds wire from the drum 12 on to the drum 3, the arm 7 runs in the opposite direction and winds wire off the drum 1 on to the drum 3 so that the total length of wire on the three drums diminishes. In order to control the minimum and maximum quantities of wire on the drums the arms are mounted on spindles which are connected to a counter-mechanism actuating contacts which increase or decrease the speed of the mechanism comprising the following stage of the machine. Alternatively the spindle may be connected directly to a governor mechanism.
