    Abstract: An image sensor includes a pixel array including active pixels and optical black (OB) pixels; a comparator having a first input terminal at which a pixel signal of the pixel array is applied, and a second input terminal to which a ramp signal is applied; a digital-to-analog converter (DAC) that generates an OB voltage based on dark current data obtained by reading out pixel signals of the OB pixels; and a dark current removal circuit that applies a compensation voltage corresponding to the OB voltage to at least one of the first input terminal and the second input terminal during a readout period of an active pixel.

    Abstract: Various embodiments of the present invention relate to a method and a wearable device for increasing a response rate of a display. An electronic device according to various embodiments of the present invention comprises: a display; a sensor module; and a processor electrically connected to the display and the sensor module, wherein the processor is configured to: sense movement of a user through the sensor module while the display displays a current frame image; predict a subsequent frame image on the basis of the sensed movement of the user, set overdriving information on the basis of the subsequent frame image; and display the subsequent frame image at least on the basis of the overdriving information by using the display. Other various embodiments are possible.
