Abstract
A fingerprint entry prompting method, includes: obtaining an ith entered fingerprint image, during a process of collecting and combining N fingerprint images entered in sequence to generate a fingerprint template of a user, wherein N≧i≧2, and N and i are integers; obtaining an overlap region between the ith entered fingerprint image and a determined template image, wherein the determined template image is generated by combining i-1 previously entered fingerprint images; and presenting a prompting message when the overlap region satisfies a prompting condition, wherein the prompting message is configured to instruct the user to move a finger towards a specified direction and re-enter the ith fingerprint image.
Claims18
A fingerprint entry prompting method, comprising:
- obtaining an ith entered fingerprint image, during a process of collecting and combining N fingerprint images entered in sequence to generate a fingerprint template of a user, wherein N≧i≧2, and N and i are integers;
- obtaining an overlap region between the ith entered fingerprint image and a determined template image, wherein the determined template image is generated by combining i-1 previously entered fingerprint images;
- and
- presenting a prompting message when the overlap region satisfies a prompting condition, wherein the prompting message is configured to instruct the user to move a finger towards a specified direction and re-enter the ith fingerprint image.
A fingerprint entry prompting device, comprising:
- a processor;
- and
- a memory for storing instructions executable by the processor;
- wherein the processor is configured to:
- obtain an ith entered fingerprint image, during a process of collecting and combining N fingerprint images entered in sequence to generate a fingerprint template of a user, wherein N≧i≧2, and N and i are integers;
- obtain an overlap region between the ith entered fingerprint image and a determined template image, wherein the determined template image is generated by combining i-1 previously entered fingerprint images;
- and
- present a prompting message when the overlap region satisfies a prompting condition, wherein the prompting message is configured to instruct the user to move a finger towards a specified direction and re-enter the ith fingerprint image.
A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor in a device, cause the device to perform a fingerprint entry prompting method comprising:
- obtaining an ith entered fingerprint image, during a process of collecting and combining N fingerprint images entered in sequence to generate a fingerprint template of a user, wherein N≧i≧2, and N and i are integers;
- obtaining an overlap region between the ith entered fingerprint image and a determined template image, wherein the determined template image is generated by combining i-1 previously entered fingerprint images;
- and
- presenting a prompting message when the overlap region satisfies a prompting condition, wherein the prompting message is configured to instruct the user to move a finger towards a specified direction and re-enter the ith fingerprint image.
