Abstract: An image sensor includes a pixel array including at least one active pixel and at least one line-optical black (L-OB) pixel arranged in a matrix including first to nth rows and first to mth columns, the pixel array configured to output a pixel signal and a dark-level offset signal in units of columns during a read-out operation in one of the first to nth rows; a row driver configured to output a selection control signal to the first to nth rows; and an analog-to-digital converter (ADC) block configured to digitize the pixel signal and the dark-level offset signal. In the pixel array, a dark-level offset signal is simultaneously output from an L-OB pixel in another row during the read-out operation in one of the first to nth rows. Here, ‘n’ and ‘m’ each denote an integer that is equal to or greater than ‘2’.

Abstract: In one example embodiment, a method of operating an image data processing circuit which controls an operation of an organic light-emitting diode (OLED) display includes transforming at least one first RGB value into at least one luminance value and at least one chroma value. The method further includes adjusting the at least one luminance value and the at least one chroma value based on at least one first control value. The method further includes generating at least one second RGB value based on the at least one adjusted luminance value and the at least one adjusted chroma value. The method further includes outputting the second RGB values to the OLED display.
