    Abstract: Provided is a display device for executing processing of enlarging a predetermined region (200) of an image rightward by as much as 0.25 pixels with a first pixel (251) as a reference, and processing of reducing the predetermined region (200) rightward 0.25 pixels with a seventh pixel (257) as a reference, to thereby control the predetermined region (200) to be shifted rightward. The image is thus shifted while changing a magnitude of the predetermined region (200) so that an enlarged amount and a reduced amount per one step are smaller than 1 pixel, thereby making it possible to shift the image while changing the magnitude of the image without giving a visually unnatural impression. The display device can be applied to processing using digital signals because a lighting state of each pixel is controlled. The shift of the image can be easily performed without executing pixel conversion processing or the like.

  • Patent number: 6639588
    Abstract: An image display apparatus capable of adjusting a display picture by an input unit through a computer body is disclosed. When the user inputs a control instruction for adjusting the display picture of the display unit by the input unit connected to the computer body, a control signal addition circuit prepares a control signal Sc corresponding to the control instruction and adds the control signal to a video signal R, G or B or a synchronizing signal Hs or Vs produced by a display control circuit during a vertical retrace period. A control signal separation circuit separates the added control signal Sc from the video signal R, G or B or the synchronizing signal Hs or Vs produced by the control signal addition circuit. A display control circuit produces adjustment signals Sa and Sb on the basis of the control signal from the control signal separation circuit to adjust a video circuit and a deflection circuit.

  • 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: RE40422
    Abstract: A monitor control system capable of reprogramming the function of a LCD monitor. The monitor control system utilizes VGA signal lines for video signal transmission during normal mode of operation and the same VGA signal lines for transmitting erase/record commands and data when the erasable programmable ROM inside the monitor demands reprogramming. Using an isolator circuit in the monitor control system for isolating an erase/record pathway of an erasable programmable ROM from a normal video pathway, data within the erasable programmable ROM can be modified without opening up the monitor casing. Hence, the modification of monitor function is much more convenient.

  • Patent number: RE41631
    Abstract: Gamma correction or other power Power functions and other self-similar functions are generated for correcting the light intensity for digital pixels implemented in hardware. Two levels of mapping of segments are preformed to reduce the total number of segments for a given precision. The A range of inputs is divided into successively smaller segments. Two levels of mapping of segments are performed. Each segment is smaller than the next by a factor of 1/a for a first or primary level, or 1/b for a second level of segments. All inputs are mapped of scaled up to the input range of the largest segment in the primary level. Then the largest primary segment is further divided into several second-level segments, and the input is again mapped or scaled into the largest of the second-level segments. Gamma correction The function is performed on the input scaled into the largest second-level segment. A linear approximation within the largest second-level segment is used.
