摘要： For control and correction of deflection parameters especially of convergence, a grid pattern is displayed on the picture screen of a television device. For control of the convergence parameters and the evaluation of the correction values the crossing points of the grid pattern are marked by a cursor. The cursor is formed by at least one irregularity in the grid pattern being, regular otherwise. The irregularity may consist in an omission within the grid pattern like an interruption within one horizontal or vertical grid line. An image signal generator for the grid pattern with position cursor includes a raster generator, a grid generator, a cursor generator, and means for combining a grid signal from the grid generator and a cursor signal from the cursor generator so as to inhibit the grid signal corresponding to locations on the grid pattern where the position cursor is visible by an absence of display of portions of the grid pattern.

摘要： A switchable digital filter interpolates distortion correction values. The distortion correction values together with interpolated distortion correction values are supplied as an output. Proper operation of the digital filter is disturbed by transient signals occurring during horizontal retrace. The digital output is converted to an analog convergence correction signal. The digital to analog converter has an operating frequency and generates a transient signal during horizontal retrace as the operating frequency increases due to an increased horizontal scanning rate. A low pass filter receives the analog convergence correction signal and generates an analog deflection signal. An auxiliary deflection coil is driven by the analog deflection signal. The digital filter is switched off during the horizontal retrace. The digital filter is thus protected from disturbance by the transient signal and the digital to analog converter is protected from exceeding a maximum operating frequency.

摘要： A memory and a switchable digital filter supply different numbers of digital distortion correction values. The supplied distortion correction values are converted to an analog distortion correction signal. A passive, analog low pass filter for the analog distortion correction signal generates an analog deflection signal. The low pass filter is optimized only for those of the analog deflection signals having a given sample rate. A controller varies the different numbers of the supplied distortion correction values to maintain the given sample rate of the analog deflection signal for different horizontal scanning rates. The controller selectively implements respective operating modes for different horizontal scanning frequencies in which no interpolated distortion correction values are supplied or different numbers of interpolated distortion correction values are supplied.

摘要： A controllable reflecting device having an array of bi-axial mirrors that are capable of pivoting in at least four directions is described. At least three primary colored light beams are directed at each of the bi-axial mirror in three of the four pivoting directions, one for each of the primary colored light beams and a single colored beam is reflected and directed toward a projection lens. In the fourth pivoting direction, no color beam is directed to the projection lens and black is projected.
