  • Patent number: 5619227
    Abstract: Each display control block processes color pixel data stored in a refresh memory to convert the processed data into 1-bit monochromatic picture signals. At this time, the color information possessed by the respective color pixel data are converted in a form in which the color information possessed by the color pixel data may be expressed on a monochromatic display panel. The monochromatic picture signals produced by plural display control blocks are synthesized in a display synthesizing circuit and converted into one monochromatic picture signal. At this time, the display synthesizing circuit synthesizes the signals with different degrees of display preference so that the picture surface having a lower display preference is not seen on the picture surface having a higher display preference.

  • Patent number: 5068651
    Abstract: An image display apparatus includes a programmable raster line address generator that repeatedly displays programmably selected raster lines of a stored pattern a predetermined number of times to enlarge the stored pattern when displayed. Programmable registers store integers that select which raster lines are to be repeatedly displayed.

  • Patent number: 5047759
    Abstract: An image display system is disclosed, which comprises a sync signal generator for receiving a clock selected by a clock selection circuit and generating sync signals conforming to a display screen, a timing signal generator for generating various timing signals, a refresh memory for storing pixel data for display on said display screen, a display data processor for converting pixel data read out from the refresh memory into said timing signals, and a display medium having a fixed display resolution for receiving the outputs of said display data processor and sync signal generator for display of data. The image display system further comprises a clock selection controller for either allowing or inhibiting the clock selection by the clock selection circuit.

  • Patent number: 4935731
    Abstract: An image display apparatus is disclosed, in which a programmable counter is provided with a separate counter with the output thereof varied cyclically with the counting of horizontal sync signal pulses, the output of the counter is used to cull out the horizontal sync signal pulses supplied to the programmable counter, and pixel data of the same line is read out from a reflesh memory at least twice in a period, in which the input is culled. A display on a display panel having a fixed display resolution thus is obtained of display data of a lower resolution than the fixed display screen resolution.

  • Patent number: 4380825
    Abstract: An automatic sweep digital tuning circuit includes an up-down counter, a digital-to-analog converter, an electronic tuner, an automatic sweep control circuit and an automatic frequency fine control circuit. The up-down counter performs a count-up or count down operation under the control of the automatic sweep control circuit and the automatic frequency fine control circuit. The digital-to-analog converter converts the digital output of the up-down counter into a DC voltage. The electronic tuner receives the DC voltage and generates a tuning frequency. The automatic frequency fine control circuit finely controls the tuning frequency of the electronic tuner after the automatic frequency sweep by the automatic sweep control circuit has been stopped. A count down circuit forces the up-down counter to perform a count down operation to compensate for a time delay caused by the digital-to-analog conversion.
