摘要：: <p>Method for enhancing the resolution of colour television cameras with three semi-conductor image sensors which generate by a horizontal displacement of one third of the image point period three output signals which are outshifted by 120oC. Thus, in addition to standard signals for luminance and chrominance, another luminance signal is matrixed by the weighing addition of output signals from the sensors, is filtered in a high-pass filter and is added to the low-pass filtered standard-conform luminance signal to produce a resultant luminance signal. After the passage through the high-pass filter, a control signal is derived from the other lumnance signal, whereby colour difference signals may be controlled according to amplitudes.</p>
