  • Picture quality control method and image display using same
    Patent number: 8711187
    Abstract: A definition control method and an image display device using the same are provided. The definition control method includes displaying a first pattern and a second pattern, inputting a control value, and changing a display state of the first pattern according to the input control value, wherein a display state of the second pattern is not changed by the control value.
    Type: Grant

  • Apparatus and method for compensating compression blocking artifacts based on gray value comparisons of adjacent blocks
    Patent number: 7715648
    Abstract: An apparatus and method for compensating images in a display device is disclosed. Distortion ratios of image blocks are calculated based on a gray value difference between each of a plurality of pairs of pixels in the image blocks that face each other at a boundary between the image blocks. Compensation parameters are set based on the calculated block distortion ratios. Distortion compensation values of the image blocks are calculated based on the gray value difference and the set compensation parameters. The image blocks are then compensated according to the calculated distortion compensation values.

  • Touch switching apparatus
    Patent number: 6667563
    Abstract: A touch switching apparatus includes: a switching unit for evenly illuminating on a touch unit manipulated by a user among touch units with marks; and a driving circuit for driving the switching unit when detecting the manipulation. The touch switching apparatus includes: an insulating unit for inducing a capacitance as a user's body contacts and presented with a touch switch for manipulation of an instrument; a conductive unit for detecting a capacitance through the medium (dielectric) of a user's body contacting the insulating unit; a flat light emitting device for providing a backlight to the insulating unit to visibly express a corresponding switching unit when a body contact is detected by the conductive unit; and a drive unit for detecting whether a switch has been manipulated according to a change in a capacitance made by the conductive unit.
