An image sensor, a mobile device, and an image sensor operation method for reducing a data transmission latency are disclosed. The image sensor includes an interface circuit configured to receive compressed data from an external processor, at least one memory configured to store the compressed data, and a control logic circuit configured to decompress the compressed data based on an initialized first clock rate, wherein, after the control logic circuit decompresses the compressed data, the first clock rate is reset to a second clock rate.

A method of setting light sources in a display panel for optical fingerprint recognition is provided. The method includes driving a portion of light sources disposed to correspond to a fingerprint recognition window which is a partial region of a display panel based on initial light source setting values, obtaining initial calibration data based on reflected light of an object received by a fingerprint recognition sensor through the fingerprint recognition window while driving the portion of the light sources; and determining final light source setting values such that powers for driving light sources of different colors among the portion of the light sources are different, the final light source setting values being determined to minimize contrast of an interference signal included in the initial calibration data.
