Patent EP-0042297-B1 (EP)
IPC: H01J29/78
Filed: 1981-06-16
Granted: 1984-11-07
Abstract: A sweep generator (10) for producing a circular raster (16) of curved scanning lines (18) on the target surface of a video camera is disclosed. Each curved trace follows a substantially circular path through a scanning angle of 360 The circular raster is generated by horizontal and vertical scanning signals (28, 30) which are synchronized with the horizontal line frequency of a video receiver. The horizontal scanning signal (28) is characterized by a constant amplitude component (28A) followed by a sine wave component (28B), and the vertical scanning signal (30) is characterized by a composite waveform including a constant amplitude component (30A) followed by a sine wave component (30B) which is shifted 90° in phase with respect to the sine wave of the horizontal scanning signal.The constant amplitude components of each composite waveform are synchronized with the horizontal blanking pulse (32) which occurs during horizontal retrace of the scanning beam in the receiver, and the phase shifted sine waves are synchronized with the forward trace of each horizontal line in the receiver. This produces a one-to-one correspondence of each circular trace in the video camera with each horizontal forward trace in the receiver. The composite scanning signals are amplitude modulated by a sawtooth signal (36, 38) which is synchronized with the receiver field frequency, thereby producing the circular raster of concentric scanning lines. According to a preferred embodiment, each composite waveform is produced by a read only memory (ROM) (40,42) which is synchronously cycled at the line frequency while driving a digital-to-analog converter (44, 46). The modulating signal is generated by a sawtooth oscillator (60) which is synchronized with the receiver field frequency.

Granted: 1990-08-16
Abstract: Line (20) and field (40) deflection circuits generate line and field deflection currents in respective line (LH) and field (Lv) deflection windings to scan a raster on the phosphor screen of a square-planar picture tube having an aspherical faceplate. The asphericity of the faceplate (30) subjects the scanned raster to gullwing distortion. A gullwing distortion correction circuit (70) is responsive to signals repeating at line and field rates, respectively, for modulating the field deflection current during a line deflection period within the field deflection trace interval in a manner that corrects gullwing distortion of a corresponding raster scan line.
