摘要： A projection television apparatus has three monochromatic picture tubes disposed in a planar orientation defining a central picture tube and two outer picture tubes. Each of the picture tubes includes a deflection unit responsive to deflection currents and raster correction signals for vertical and horizontal deflection. A control circuit, including a signal generator, supplies vertical and horizontal raster correction signals formulated for the central picture tube to all three of the picture tubes and supplies additional vertical and horizontal raster correction signals formulated for the two outer picture tubes respectively to the two outer picture tubes, respectively. Conductive paths for the formulated for the central picture tube correction signals can include variable resistors for effecting small changes in signal amplitude.

摘要： A method of collecting the spactial positions of crossing points of the lines in the grid on the visible portion of the screen of a television receiver used in different modes of operation includes the steps of storing a first set of correction values for each of the crossing points. The first correction values define the spactial positions of the correction points for all modes of operation of the television receiver. Additional correction values are stored for each mode of operation. The additional correction values are generated during an overscan period and during the scanning of an initialization line which is positioned outside the visible portion of the screen and compensate for displacement of the crossing points induced by tolerances in the tube. The first correction values and the additional correction values are simultaneously applied to the deflection current of the television tube while the visible portion of the screen is scanned.

摘要： A cursor for correcting the locations of points formed by the crossing horizontal and vertical lines of a grid arranged on the screen of a television receiver. The screen has a portion illuminated by a picture and a dark portion unilluminated by the picture. The grid also has at least one line of dark-points parallel to each edge of the picture and lying outside of the picture. The cursor is configured and dimensioned to extend into the picture when the cursor covers one of the dark-points.

摘要： A method of positioning a light beam on a picture surface relative to a light sensor located on the picture surface includes the step of completely illuminating the sensor with the light beam while the sensor is exposed to ambient light and recording a first output signal. A second output signal is recorded when the sensor is exposed to only ambient light. The first and second output signals are provided to an evaluation circuit to calculate a positioning signal having a value equal to a selected percentage of the difference between the first and second output signals. The light beam is positioned relative to the sensor to expose the sensor to a percentage of the light beam which is equal to the selected percentage of the difference between the first and second signals

摘要： Convergence correction waveforms are generated for multiple vertical formats. One of a number of vertical formats is selected for displaying a video signal. The vertical formats differ by respective vertical scanning rates, respective vertical scanning heights, or both. A set of convergence correction values corresponding to a plurality of raster locations is stored for each of the different vertical scanning heights. An interpolation control value is stored for each of the vertical scanning frequencies. An interpolator is responsive to different ones of the control values for generating a different set of intermediate convergence correction values for each of the vertical scanning frequencies, from each of the sets of stored convergence correction values. The interpolator generates the intermediate convergence correction values between horizontally and vertically spaced ones of the raster locations.

摘要： A television apparatus comprises a video display having a wide format display ratio, for example approximately 16:9. A deflection circuit generates first and second selectable rasters having a common horizontal scan width corresponding to the display but having first and second vertical heights respectively, for example nominal and overscanned vertical heights. A control circuit selects one of the first and second rasters for displaying pictures from wide format display ratio video sources and conventional format display ratio video sources respectively, for example 16:9 and 4:3. A picture from the wide format display ratio video source is substantially uncropped and a picture from the conventional format display ratio video source is expanded and cropped. One of the vertical formats provides substantially no image aspect ratio distortion of the pictures as displayed. The other one of the vertical formats provides substantially no cropping of the pictures as displayed. The relative amounts of image aspect ratio distortion and cropping of the pictures as displayed are substantially inversely proportional. One of the vertical formats provides substantially no image aspect ratio distortion and substantially no cropping of the active picture portion as displayed, when the video source is in letterbox format. A convergence control system can be provided which automatically adjusts to the selected vertical format.

摘要： A system for making location adjustments on a display screen raster having horizontal and vertical lines crossing at crossing points includes a cursor which is moveable to the crossing points. The visibility of the cursor is enhanced because the horizontal and vertical lines are brighter than the cursor. The visibility of the cursor can be further enhanced by making the brightness of the cursor adjustable.

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.
