  • Patent number: 5734362
    Abstract: An arrangement and method for adjusting the brightness of an image signal having digital pixel values to produce brightness adjusted output pixel values is provided with an adder and lower and upper clamp circuits. The adder adds a brightness value to the digital pixel values of the image signal to produce adjusted pixel values and a carry-out signal. The lower clamp circuit clamps the adjusted pixel values to a lowest output pixel value when the carry-out signal and the brightness value indicate that addition of the brightness value to the digital pixel values produces adjusted pixel values below the lowest output pixel value. The upper clamp circuit clamps the adjusted pixel values to a highest output pixel value when the carry-out signal and the brightness value indicate that addition of the brightness value to the digital pixel values produces adjusted pixel values above the highest output pixel value.

  • Patent number: 5731808
    Abstract: An ergonomic computer keyboard is specially designed to allow a user to alter the line of key stroke in multiple directions. The keyboard housing is divided into three separate sections, and each section is connected to another by means of a cable. The dividing of the keyboard into three separate sections provides for a first adjustable positioning of the keys for the comfort of the user. A further adjustable positioning is facilitated by the shape of the keyboard housing since the housing is angled upwardly and is concave so that it curves up in the back. The keys are mounted perpendicular to it, and this has the effect of raising the keys at the back of the keyboard to a higher and more easily usable angle. A third adjustment of key stroke is afforded by the slidable displacement of the concavely-shaped keyboard upwardly or downwardly through the use of releasable fasteners so as to further vary key stroke alignment.

  • Patent number: 5724057
    Abstract: The generation of flicker is prevented when the contrast of a displayed image is changed. The amplitude of the data voltage whose polarity is inverted at a timing synchronized with the display cycle of an image is changed based on the tone and the designed contrast. At the same time, the position (center) of 0 V relative to the amplitude of the data voltage is offset a larger amount as the contrast increases. This corrects a change V in voltage between the electrodes under the influence of the parasitic capacity of a TFT when the TFT is turned off, so that the voltage between the electrodes is also turned off despite the polarity of the data voltage applied to the liquid crystal, even when the designated contrast is relatively high and the amplitude of the data voltage is relatively small, and even when the designated contrast is relatively low and the amplitude of the data voltage is relatively large.

  • Patent number: 5719594
    Abstract: A method and system in a data processing system are disclosed for improving video sequence image resolution when creating an enlarged final image from an initial image included within the video sequence. An enlargement factor is determined for creating a final image having a final image size from an initial image having an initial image size, where the enlargement factor is the quotient of the final image size divided by the initial image size. An intermediate factor is established to optimize the image resolution and minimizing the hardware required to produce the image. In response to the enlargement factor being less than the intermediate factor, the final image is created from the initial image utilizing the enlargement factor and bilinear interpolation. In response to the enlargement factor being greater than the intermediate factor, an intermediate image is created. The intermediate image has an intermediate size which is greater than the initial image size and less than the final image size.

  • Patent number: 5710572
    Abstract: When images of several frames captured by an image sensing device such as an electronic still-video camera are displayed on a display unit, the images are made easier to view by rotating each image in conformity with the inclination of the horizontal scanning direction of the camera, with respect to the horizontal, which prevailed when the image was captured. Several frames of compressed image data stored in a memory card or external storage unit are decompressed by a compression/expansion circuit and then stored in a compression/expansion memory. The stored compressed image data thus is read out by a thin-out/rotation circuit and the data is then thinned out, processed for movement to a designated position and processed for rotation based on angle data. The processed image data is stored in a display memory. Under the control of a display control circuit, the display unit displays the image data that has been stored in the display memory.

  • Patent number: 5703609
    Abstract: A single-line 16 character display is driven using a display driver designed to drive two independent 8 character single-line displays. Conceptually, the 16 character display is treated as the two independent 8 character displays placed side by side. The message for display is placed in a first area of driver memory corresponding to the first 8 character display. A truncated version of the same message for display, with an offset at the beginning equal to the number of characters in the first display line, is stored in a second area of driver memory corresponding to the second 8 character display line. When the message and the truncated version thereof are simultaneously displayed, an observer views a single, coherent 16 character single line display. If the message is greater than 16 characters, the driver scrolls both the message for display and the truncated version thereof, creating a single scrolled message from the point of view of the observer.
