A method of operating a fingerprint sensing system, the method comprising: obtaining a partial image sensed with respect to a portion of a fingerprint region of a user; analyzing a distribution of fingerprint pitches (424, 425, 433) from the obtained partial image, wherein the distribution of fingerprint pitches comprises a distribution of ridge intervals between ridge lines included in the fingerprint region; determining an adaptive resolution at which to operate the fingerprint sensing system with respect to the user, based on a size of a super-pixel corresponding to the analyzed distribution of fingerprint pitches such that the adaptive resolution has a correlation that is inversely proportional to the size of the super-pixel, wherein a sub-pixel corresponds to a crossing of a drive electrode with a detection electrode, wherein a super-pixel represents an array of sub-pixels defining a sensing area, and the size of the super-pixel is determined by the number of sub-pixels grouped together; setting the fingerprint sensing system to the determined adaptive resolution; and obtaining a fingerprint image of the user with respect to the fingerprint region sensed by using the fingerprint sensing system operated at the determined adaptive resolution, wherein the analyzing of the distribution of fingerprint pitches comprises analyzing at least one of a maximum fingerprint pitch, a most frequent fingerprint pitch, a minimum fingerprint pitch, and an average fingerprint pitch, with respect to the user, wherein the determining of the distribution of fingerprint pitches comprises determining the size of a super-pixel by determining the number of sub-pixels to maximize a difference in an amount of change in mutual capacitance between a ridge and a valley when the fingerprint region is sensed, and the determined adaptive resolution is inversely proportional to the determined size of a super-pixel, wherein the determining of the adaptive resolution comprises determining the adaptive resolution is to be decreased when a fingerprint pitch is analyzed to be relatively large in the analyzed distribution, and determining the adaptive resolution is to be increased when a fingerprint pitch is analyzed to be relatively small in the analyzed distribution, within a maximum sensing resolution supported by the fingerprint sensing system. obtaining a partial image sensed with respect to a portion of a fingerprint region of a user; analyzing a distribution of fingerprint pitches (424, 425, 433) from the obtained partial image, wherein the distribution of fingerprint pitches comprises a distribution of ridge intervals between ridge lines included in the fingerprint region; determining an adaptive resolution at which to operate the fingerprint sensing system with respect to the user, based on a size of a super-pixel corresponding to the analyzed distribution of fingerprint pitches such that the adaptive resolution has a correlation that is inversely proportional to the size of the super-pixel, wherein a sub-pixel corresponds to a crossing of a drive electrode with a detection electrode, wherein a super-pixel represents an array of sub-pixels defining a sensing area, and the size of the super-pixel is determined by the number of sub-pixels grouped together; setting the fingerprint sensing system to the determined adaptive resolution; and obtaining a fingerprint image of the user with respect to the fingerprint region sensed by using the fingerprint sensing system operated at the determined adaptive resolution, wherein the analyzing of the distribution of fingerprint pitches comprises analyzing at least one of a maximum fingerprint pitch, a most frequent fingerprint pitch, a minimum fingerprint pitch, and an average fingerprint pitch, with respect to the user, wherein the determining of the distribution of fingerprint pitches comprises determining the size of a super-pixel by determining the number of sub-pixels to maximize a difference in an amount of change in mutual capacitance between a ridge and a valley when the fingerprint region is sensed, and the determined adaptive resolution is inversely proportional to the determined size of a super-pixel, wherein the determining of the adaptive resolution comprises determining the adaptive resolution is to be decreased when a fingerprint pitch is analyzed to be relatively large in the analyzed distribution, and determining the adaptive resolution is to be increased when a fingerprint pitch is analyzed to be relatively small in the analyzed distribution, within a maximum sensing resolution supported by the fingerprint sensing system.
