  • Image compensation method applied to display and associated control circuit
    Patent number: 10062359
    Abstract: A control circuit applied to a display includes an adjustment parameter generating circuit, an adjustment circuit, a compensation circuit, an image detail compensating circuit and an output circuit. The adjustment parameter generating circuit determines an adjustment parameter according to a backlight intensity corresponding to a pixel in a frame. The adjustment circuit adjusts a pixel value of the pixel according to the adjustment parameter to generate an adjusted pixel value. The compensation circuit compensates the adjusted pixel value according to a compensation curve go generate a compensated pixel value. The compensation curve includes a non-linear segment. The image detail compensating circuit generates a detail compensation value according to an edge factor of the pixel. The output circuit adjusts the compensated pixel value according to the detail compensation value to generate an output pixel value of the pixel.
