    Abstract: An image processing circuit includes a receiver, at least one memory, a recognition circuit, a calculation circuit and a compensation circuit. The receiver is configured to receive a current image frame and a plurality of previous image frames. The at least one memory is configured to store the plurality of previous image frames. The recognition circuit is configured to select a first previous image frame or a second previous image frame among the plurality of previous image frames from the at least one memory. The calculation circuit is configured to calculate a compensation value for the current image frame according to at least one of the first previous image frame and the second previous image frame by referring to a lookup table (LUT). The compensation circuit is configured to modify a current image data of the current image frame by using the compensation value.

    Abstract: A display control circuit transforms a plurality of input points of an input image to a plurality of target subpixels of a display panel. In the display panel, a first row of the target subpixels and a second row of the target subpixels are non-aligned in a vertical direction. The display control circuit includes a subpixel rendering circuit. The subpixel rendering circuit maps a first row of the input points to the first row of the target subpixels, and maps a second row of the input points to the second row of the target subpixels. The coordinates of the first row of the input points are respectively equivalent to the coordinates of the first row of the target subpixels. The coordinates of the second row of the input points are respectively equivalent to the coordinates of the second row of the target subpixels being shifted in a horizontal direction.

    Abstract: The invention provides a color calibration device, a color calibration method and a calibration table generation method. The color calibration device includes a calibration table circuit, a ratio circuit and an image processing circuit. The calibration table circuit provides a selected calibration table including a plurality of zone calibration parameters. Each of the zone calibration parameters corresponds to a corresponding zone among a plurality of zones of a display panel. The ratio circuit calculates a subpixel calibration parameter corresponding to a current subpixel according to at least one of the zone calibration parameters in the selected calibration table. The image processing circuit calibrates original subpixel data of the current subpixel according to the subpixel calibration parameter to generate calibrated subpixel data of the current subpixel.
