  • Patent number: 7995851
    Abstract: A method of and an apparatus for image enhancement taking ambient illuminance into consideration. The image enhancement method includes calculating an original-luminance contrast which is a luminance contrast with respect to an original-luminance of pixels forming an original image, calculating a fade-luminance by reflecting the variation of perceived luminance based on an ambient illuminance into the original-luminance, calculating a defade-luminance by converting the fade-luminance to maintain the original-luminance contrast, and calculating a display-luminance by reflecting the variation of perceived luminance by the ambient illuminance into the defade-luminance. Improving luminance contrast through adjustment of luminance based on ambient illuminance, effectively reduces the fade phenomenon.

  • Patent number: 7432671
    Abstract: A level-shifting inverting circuit provides a blanking signal to Grid 1 of a CRT. The circuit provides the blanking signal from a blanking logic signal according to a voltage transfer characteristic that is substantially similar to the voltage transfer characteristic of a standard CMOS inverter. Also, the level-shifting inverting circuit includes a switch circuit that includes a differential pair. The differential pair has the blanking logic signal at one input, and a bias signal at the other input. The switch circuit is coupled to a voltage divider that provides an output voltage that is pre-determined by a resistor ratio when the switch circuit is open. If the blanking logic signal is low, the switch circuit is open. Conversely, if the blanking logic signal is high, the switch circuit is closed, and sinks current from the voltage divider, causing the output voltage to correspond to a second pre-determined voltage level.

  • Patent number: 6795043
    Abstract: A first PLL circuit (100) receives a flyback pulse (VFB) as a reference signal and outputs a clock signal (CLK1), and a delay circuit (200) outputs a flyback delay signal (VFBD) having a predetermined delay time corresponding to the amount of horizontal movement on a screen. A second PLL circuit (300) receives a horizontal synchronizing signal (VHSYNC) and the flyback delay signal (VFBD) as a reference signal and a compared signal, respectively, and generates a horizontal drive pulse (VHD). A deflection yoke (12) receives the horizontal drive pulse (VHD) and generates a flyback pulse, and a step-down transformer circuit (16) outputs the flyback pulse (VFB) whose voltage is lowered. With this constitution, it becomes possible to generate a stable horizontal drive pulse which causes no jitter on the screen when a PIN balance correction, a KEY balance correction and a horizontal position adjustment of a CRT are performed by digital processing.

  • Patent number: 6577285
    Abstract: A gamma corrector inputs a primary color signal as an image signal to each of the differential amplifiers which are connected in parallel to each other and mixes a plurality of output signals which are outputted from the four differential amplifiers to output an image signal to which a plurality of gamma correction is applied. Each of the differential amplifiers amplifies and outputs the inputted primary color signal with a different gain characteristic so that the gain characteristic of the signal obtained by mixing the output signals varies at two inflection points. The two-point gamma correction is applied to the inputted primary color signal so that a signal level at the side of a black level is turned down and the signal level at the side of a white level is turned up.

  • Patent number: 6559609
    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.

  • Patent number: 6449517
    Abstract: A technique for collectively setting a factory mode of operation of a monitor offers adjustments or modifications for particulars of mode data to meet user requirements, by transmitting a set of factory mode timing data from an external controller to an electrically erasable programmable read only memory using a serial interface data communication. A factory mode data transmission process includes the steps of transmitting a start data signal to a microcomputer in a monitor when a storage key input is fed to the external controller, repeatedly sending the timing data until a mode end signal is input and sending a mode end data to the microcomputer when a mode end signal is input. In addition, a factory mode data receiving process includes the steps of sending back the start data received to the external controller, storing mode timing data received into a factory mode address reserved in a memory in the monitor and ending the reception of mode timing data when mode end data is inputted.

  • Patent number: 6437761
    Abstract: A method for storing status information prior to shutdown of a video monitor due to a failure. An indication of an operational parameter is obtained. Based on the indication, it is determined if the failure occurs warranting shutdown. If the failure occurs, status information is stored in a non-volatile memory for later retrieval during repair. A shutdown sequence is generated to disable the video monitor.

  • Patent number: 6424324
    Abstract: An emitter follower amplifier is coupled between the output of a high voltage video amplifier and the cathode of a kinescope for reducing the effective capacitance presented to the video amplifier that is attributable to the kinescope cathode, socket, spark gaps, and related stray capacitances. A secondary undesired capacitance loading of the video amplifier is effectively reduced by regulating the collector-emitter voltages of the emitter follower output transistors at substantially constant values thereby improving parameters such as slew rate and bandwidth of the overall video display system. Nonlinear circuitry in the follower circuit facilitates accurate AKB current sensing and provides simplification of the voltage regulation circuitry. White limiting circuitry is included within the video amplifier for reducing excess peak white drive that results in objectionable smears.

  • Publication number: 20020036599
    Abstract: Disclosed are methods for driving an electron-emitting device, an electron source, and an image-forming apparatus, driving circuits for an electron source and an image-forming apparatus, and an electron source and an image-forming apparatus, with each of which electron emission is effectively halted. A voltage (Vg−Vc)>0 is applied to an electron-emitting device placed in a driving state in which electrons should be emitted, thereby having the electron-emitting device emit electrons. A voltage (Vg−Vc)<0 is applied to an electron-emitting device placed in a halt state in which no electrons should be emitted, thereby having the electron-emitting device halt electron emission.

  • Publication number: 20020036598
    Abstract: A first PLL circuit (100) receives a flyback pulse (VFB) as a reference signal and outputs a clock signal (CLK1), and a delay circuit (200) outputs a flyback delay signal (VFBD) having a predetermined delay time corresponding to the amount of horizontal movement on a screen. A second PLL circuit (300) receives a horizontal synchronizing signal (VHSYNC) and the flyback delay signal (VFBD) as a reference signal and a compared signal, respectively, and generates a horizontal drive pulse (VHD). A deflection yoke (12) receives the horizontal drive pulse (VHD) and generates a flyback pulse, and a step-down transformer circuit (16) outputs the flyback pulse (VFB) whose voltage is lowered. With this constitution, it becomes possible to generate a stable horizontal drive pulse which causes no jitter on the screen when a PIN balance correction, a KEY balance correction and a horizontal position adjustment of a CRT are performed by digital processing.
