Abstract: A method, display device and module for processing a high dynamic range (HDR) image, are capable of improving visibility according to illuminance. In one embodiment, illuminance information sensed through an illuminance sensor is received, a perceptual quantizer electro-optical transfer function (PQ-EOTF) is adjusted, and gray level information of a first HDR image is converted into luminance information of a second HDR image using the adjusted PQ-EOTF. The luminance information of the second HDR image is analyzed to calculate a high-luminance rate of occupancy of pixels having target peak luminance or more of a display device in the second HDR image. The second HDR image is luminance-mapped to a third HDR image suitable for the display device using a mapping function changed according to the high-luminance rate.
