Abstract: According to an embodiment, an electronic device may include at least one processor, a display, a memory configured to store image frames, and a display controller configured to output the image frames. The at least one processor may be configured to transmit a first image frame to be output through the display, based on a first timing signal received from the display controller, identify a state of the electronic device, transmit first control information for changing a timing of the first timing signal, in response to transmitting the first control information for changing the timing of the first timing signal, receive a second timing signal from the display controller, and transmit, to the memory, a second image frame to be output through the display, based on the received second timing signal. The timing of the second timing signal may differ from the timing of the first timing signal.

Abstract: Certain embodiments relate to an apparatus and method for recognizing a fingerprint on the basis of a driving scheme to improve sensitivity of a fingerprint sensor in an electronic device. In one embodiment, the electronic device may include a touch panel comprising a plurality of electrodes and a plurality of channel electrically coupled in a designated direction with the plurality of electrodes in at least part of designated regions, a touch control circuit for driving the touch panel, and a processor, wherein the processor is configured to identify an input of an external object in the designated regions; acquire a first image for the external object in a state where two or more channels out of the plurality of channels are coupled by the touch control circuit, based at least on the input; acquire a second image for the external object in a state where another two or more channels out of the plurality of channels are coupled by the touch control circuit, based at least on the input; and authenticating the external object with the first image and the second image, thereby generating fingerprint information.
