Samsung patents display settings that adjust image edges for low vision users

1. A display device, comprising: memory storing a program including at least one instruction; and at least one processor, comprising processing circuitry, connected to the memory and configured to execute the at least one instruction of the program stored in the memory, wherein at least one processor, individually and/or collectively, is configured to: identify preferred intensity information indicating a first preferred intensity among a plurality of preferred intensities associated with image processing based on a low vision mode, based on an input; perform edge thickness adjustment processing on an input image based on edge thickness setting information corresponding to the first preferred intensity; perform image quality adjustment processing on the image on which the edge thickness adjustment processing is performed, based on image quality adjustment setting information corresponding to the first preferred intensity; and adjust a sharpness for the image by increasing brightness by applying overshoot to pixels belonging to a first area among pixels adjacent to the edge and by decreasing brightness by applying undershoot to pixels belonging to a second area different from the first area, based on setting information for adjusting the sharpness according to the first preferred intensity included in the obtained image quality adjustment setting information, wherein the first area corresponds to an inner area of an object associated with the edge, and the second area corresponds to an outer area of the object, wherein the memory includes edge thickness setting information corresponding to each of the plurality of preferred intensities and image quality adjustment setting information corresponding to each of the plurality of preferred intensities, and wherein each image quality adjustment setting information includes setting information for adjusting at least one of a brightness, a dynamic contrast ratio, a sharpness, or a color for the image according to a corresponding preferred intensity.
