Abstract
Provided is a method of processing data corresponding to a fingerprint image including obtaining first image data corresponding to a group including a plurality of pixels, and dividing the first image data into second image data corresponding to each of the plurality of pixels based on a plurality of weights corresponding to the plurality of pixels, respectively.
Claims17
A method of processing data corresponding to a fingerprint image, the method comprising:
- obtaining first image data corresponding to a group comprising a plurality of pixels;
- and
- dividing the first image data into second image data corresponding to each of the plurality of pixels based on a plurality of weights corresponding to the plurality of pixels,
- wherein the dividing comprises obtaining a value of the second image data by summing a combination of a value of the first image data with each of the plurality of weights corresponding to the plurality of pixels included in the group, and
- wherein the plurality of weights are determined based on a plurality of mutual capacitances between driving electrodes and detection electrodes constituting the plurality of pixels.
2 more elements
A data processing apparatus comprising:
- at least one processor configured to execute instructions in a computer program;
- and
- at least one memory storing at least a part of the computer program,
- wherein the at least one processor is further configured to obtain first image data corresponding to a group comprising a plurality of pixels and divide the first image data into second image data corresponding to each of the plurality of pixels based on a plurality of weights corresponding to the plurality of pixels, and
- wherein the at least one processor is further configured to obtain a value of the second image data by summing a combination of a value of the first image data with each of the plurality of weights corresponding to the plurality of pixels included in the group, and
- wherein the plurality of weights are determined based on a plurality of mutual capacitances between driving electrodes and detection electrodes constituting the plurality of pixels.
3 more elements
A data processing apparatus comprising:
- at least one processor configured to execute instructions in a computer program;
- at least one memory storing at least a part of the computer program;
- a transmission circuit configured to provide driving signal to a plurality of driving electrodes;
- and
- a reception circuit configured to determine electric signals from a plurality of detection electrodes that cross the plurality of driving electrodes,
- wherein the at least one processor is further configured to obtain first image data corresponding to a group comprising a plurality of pixels and divide the first image data into second image data corresponding to each of the plurality of pixels based on a plurality of weights corresponding to the plurality of pixels, and
- wherein the at least one processor is further configured to obtain a value of the second image data by summing a combination of a value of the first image data with each of the plurality of weights corresponding to the plurality of pixels included in the group, and
- wherein the plurality of weights are determined based on a plurality of mutual capacitances between driving electrodes and detection electrodes constituting the plurality of pixels.
