  • Patent number: 5801767
    Abstract: An image screen automatic adjustment apparatus for a video display monitor device is provided. The apparatus includes a microprocessor for handling the operation of the monitor device and for implementing the image screen adjustments. The monitor device has a switch for enabling the image screen automatic adjustment. Push button processor circuitry is coupled between the switch and the microprocessor for signalling to the microprocessor when the switch is enabled. Image inspection circuitry is coupled to the microprocessor for outputting horizontal and vertical image signals and horizontal front-back porch signals. When the image screen automatic adjustment switch is enabled, the image inspection circuitry provides the horizontal and vertical image signals and the horizontal front-back porch signals to the microprocessor for implementing an optimization analysis processing to obtain a set of optimized control parameters including a vertical size parameter V.sub.size, a vertical position parameter V.sub.

  • Patent number: 5703661
    Abstract: A control apparatus adapted to adjust the image screen display characteristics of a video monitor. The apparatus comprises a microprocessor, an encoder, and a rotary input signal processor. The microprocessor implements operation and adjustment control of the monitor. The encoder provides a rotary knob that a user of the monitor device may rotate in either direction for generating a pair of pulse signals. The rotary input signal processor is coupled between the microprocessor and the encoder for receiving the pair of pulse signals generated by the encoder and reshaping the pulses for input to the microprocessor. The microprocessor receives the reshaped pulse signals to determine the direction of rotation and the range of rotation of the encoder. The determined direction and speed of rotation are utilized as the basis for the adjustment of the image screen of the video monitor device.
