Abstract: An image processing method includes transforming input image data into a histogram, equalizing the histogram using a cumulative distribution function, setting a first weight value based on the equalized histogram and a first reference value, generating a first tone curve based on the equalized histogram and the first weight value, generating a final output tone curve by applying a second weight value to the first tone curve and an output of a second tone curve applied to the input image data, and generating output image data based on the final output tone curve and the input image data.

Abstract: An image processing device is provided. The image processing device includes: an image quality enhancement circuit configured to generate second image data indicating a plurality of pixel values corresponding to a quadrangular shape by performing image quality enhancement processing on first image data; a map decoder configured to read a map, which includes a plurality of pixel adjustment values for adjusting brightness of a first region of the second image data corresponding to a curved edge of a display panel, from a memory and provide alpha values indicated by the map; a processing circuit configured to generate third image data by adjusting the brightness of the first region by applying the alpha values to the second image data; and a transmission circuit configured to output the third image data to a display driving integrated circuit.
