Abstract: A display device includes a display panel, a plurality of readout circuits, and a deviation corrector. The display panel includes a plurality of pixels. The readout integrated circuits perform a readout operation of detected values including degradation information of the pixels, via readout lines connected to the pixels, when a degradation detecting operation is performed. The deviation corrector calculates weighted values to correct operating deviation of the readout integrated circuits based on an average of initial values. The deviation corrector generates corrected image data to correct input image data based on the weighted values. The initial values correspond to the detected values output from the readout integrated circuits when the display panel is in an initial state in which the pixels are non-degraded.

Abstract: An image processor includes a scaling unit configured to output converted data by resizing first image data; and a rendering unit configured to receive second image data, to output rendering data by rendering the second image data, and to calculate a target rendering data value based on data values corresponding to a first block of M*N among the second image data, where each of M and N is an integer greater than or equal to 2. Here, the second image data is the converted data, or the first image data is the rendering data.

Abstract: An image processing apparatus includes: a pattern identification unit configured to perform pattern identification for first image data; a first data conversion unit configured to perform first data conversion for the first image data, after a pattern of the first image data is identified, to generate second image data; a second data conversion unit configured to perform second data conversion for the second image data to generate third image data; and a process selection unit configured to determine whether or not to perform at least one of the pattern identification, the first data conversion, or the second data conversion according to a measured value that is input from an outside or an on/off state of a call mode.
