Abstract: An image display device well suited for a multi-scanning type monitor includes a video signal measurement circuit that detects a horizontal synchronization frequency fH and a vertical synchronization frequency fV from an input image signal that conforms to the GTF Standard. A main control portion calculates timing data relative to a waveform of the signal (21) using the frequencies fH and fV, calculates adjustment parameters for adjusting a size and a position using this timing data, and sets the adjustment parameters to deflection control circuits, so that an image of the image signal may be displayed well on a CRT. Since the timing data is calculated using the synchronization frequencies fH and fV of the input image signal, it is possible to save on a memory capacity without storing timing data that corresponds to a plurality of different kinds of image signals.

Abstract: A display mode switching device and method automatically switches a display mode of a television set to an overscan mode or to an underscan mode depending on a content of a screen. In a case of connecting a television set to a computer, a call from an application for an API in an OS is detected by a device driver when a user starts playing a DVD or a game. Accordingly, an output mode for the television set is switched to the overscan mode. In this way, a motion video or a game is displayed on the television set in the overscan mode. Meanwhile, when the user finishes playing the DVD or the game, a call for the API to release resources is detected by the device driver, and the output mode is restored to the underscan mode. In this way, a computer screen is displayed on the television set in the underscan mode.

Abstract: A raster center control circuit for a CRT-type display device that automatically determines a correct horizontal center position of a raster, regardless of a horizontal sync frequency input from a video card. The raster center control circuit includes a horizontal deflection circuit, electrically connected to a horizontal deflection yoke, to supply the horizontal deflection yoke with a parabolic wave signal used to determine a horizontal center position of the raster. A memory device stores predetermined values for raster control according to horizontal sync signal frequencies. A microprocessor determines a frequency of a horizontal sync signal and generates a raster control signal by converting one of the predetermined values stored in the memory device into a raster control signal according to the predetermined frequency. An operational amplifier, connected to the horizontal deflection circuit, controls the horizontal center position of the raster by summing the raster control signal with the parabolic wave signal of the horizontal deflection yoke. The operational amplifier is operated by an independent voltage source. A reference of the independent voltage source is applied to a non-inverting input of the operational amplifier, and is coincident with the parabolic wave signal of the horizontal deflection yoke.

Abstract: 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.
