摘要： The amount of correction of horizontal linearity can be adjusted and the amplitude of a horizontal deflection current can be suppressed. A switching element (11) is provided between both ends of an S-distortion correction capacitor (5) connected in series to a horizontal deflecting coil (4), so that the switching element (11) is kept on during a horizontal blanking interval to release the electric charge accumulated in the S-distortion correction capacitor (5) and the on-time of the switching element (11) is controlled to carry out linearity correction in a horizontal cycle.

The distortion correcting section (260) has a correcting-image supply section that supplies, to the image projecting section, a correcting image for use in compensating for a distortion of the output image, and an image processing section that determines an amount of a peak shift of from a peak in lightness on the virtual projection plane to a peak in lightness on the real projection plane, according to the imaged information using the correcting image, and previously distorts the input image in a manner compensating for a distortion in the output image, according to the peak shift amount determined. The correcting-image supply section (260) has a correcting-image modifying section that modifies the correcting-image in a manner approximating, to an angle of the inclination, an amount of an angular change caused responsive to the peak shift as viewing the peak from the image projecting section (100,110,120,130).

摘要： A write PLL circuit generates a write clock signal for writing a video signal into a line memory. A readout PLL circuit generates a read clock signal for reading out the video signal stored in the line memory. An inner pincushion distortion correction voltage generation circuit modulates a correction waveform in the horizontal scanning period of time by a correction waveform in the vertical scanning period of time, to generate an inner pincushion distortion correction waveform, and adds a DC correction pulse to the inner pincushion distortion correction waveform and outputs the inner pincushion distortion correction waveform as an inner pincushion distortion correction voltage. A capacitive coupling circuit superimposes the inner pincushion distortion correction voltage on an output voltage of a loop filter of the readout PLL circuit, and feeds the inner pincushion distortion correction voltage to a VCO as a control voltage.

摘要： In a CRT display apparatus, a horizontal distortion correction apparatus is provided for correcting horizontal distortion of an image by applying a residual phase to control the phase of a horizontal deflection current is provided. The horizontal distortion correction apparatus (HDCp) corrects horizontal distortion of an image caused by an assembly error of the CRT display apparatus for displaying an image by scanning a video signal (Si), based on a horizontal synchronizing signal included in the video signal (Si). The horizontal distortion correction apparatus (HDCp) includes a PLL (14) supplying the horizontal deflection current (Ihd) to a video signal controller (12) for displaying an image on the CRT. A distortion-correcting waveform generator (100) is scanned by the user, applying a wave signal (Sw) having a desired waveform to the PLL (14) to provide a residual phase for the horizontal deflection current (Ihd) to control the phase thereof. As a result, the image without horizontal distortion is displayed on the CRT display apparatus.

摘要： Series connected first to fourth reactor coils (12-15) are wound on a core (33) and connected in series with a horizontal deflection coil (11). A coil (22) is also wound on the core and connected in series with a vertical deflection coil. The core (33) is provided with two permanent magnets (34,35) and magnetic bias is applied to the first to fourth reactor coils. A total inductance of first to fourth reactor coils (12-15) is controlled by a vertical deflection current passing through the coil and thereby, a correction amount of an amplitude of a horizontal deflection current is changed.
