    摘要: An image processing apparatus includes a computation unit that determines an interpolation process starting point and gradient on the basis of a change point at which a difference between pixel values of adjacent pixels of an image signal is greater than zero and is less than or equal to a predetermined threshold value, wherein a position of a pixel scanned earlier or later than the change point by substantially one-half a continuous width of pixels having an identical grayscale value is set as the starting point and the gradient is determined based on a difference between pixel values before and after the change point and the continuous width, and a conversion unit that converts pixel values of the image signal on the basis of the determined starting point and gradient so that a grayscale change from the interpolation process starting point in the image signal corresponds to the gradient.

    摘要: An apparatus and method for driving a display panel, and more particularly, an apparatus and method for easily generating a programmable signal to drive a digital display panel without re-designing a drive signal generating apparatus according to the specifications of the digital display panel including its size, the number of scan lines, and types of input signals. The apparatus includes a memory, a decoder, and an output waveform generating circuit. The memory stores information to generate a plurality of drive pulse signals necessary for driving the display panel. The decoder reads information stored in an address assigned according to a predetermined control sequence from the memory and then edits the read information so as to be suitable for specifications of the display panel. The output waveform generating circuit generates drive pulse signals corresponding to the information read by the decoder.

The apparatus includes a data converter, which processes an image signal such that a gray level of the image signal exists within a predetermined range; an error diffuser, which diffuses an error between a gray level of a current pixel in a current frame of the image signal and a gray level of the current pixel in the current frame after being subjected to gray-level change, to pixels adjacent to the current pixel in the current frame; a gray-level changing unit, which calculates a difference in a gray level between each pixel in the current frame of the image signal and a pixel corresponding to the current frame pixel in a previous frame of the image signal, and changes the gray level of the current frame pixel based on the gray level difference such that transition in an emission pattern of higher weighted subfields among subfields, which illuminate according to the gray level of the current frame pixel, between the current frame pixel and the previous frame pixel is minimized; and a subfield converter, which converts a subfield according to a gray level output from the gray-level changing unit.
