Abstract
A texture image compensation method, a texture detection method and a device, and an electronic device are provided. The texture detection method includes: performing an image difference calculation on a first texture image acquired by a texture detection device and a foreign object correction image acquired by the texture detection device to compensate foreign object information in the first texture image, and to acquire a second texture image; performing and the texture detection by using the second texture image.
Claims20
A texture image compensation method, comprising:
- performing an image difference calculation on a first texture image acquired by a fingerprint detection device and a foreign object correction image acquired by the fingerprint detection device to compensate foreign object information in the first texture image, and to acquire a second texture image.
A method of acquiring a foreign object correction image of a fingerprint detection device, the fingerprint detection device comprising a fingerprint sensor, the method comprising:
- in a case where no fingerprint is entered, collecting an initial image of a fingerprint entering region by the fingerprint sensor;
- and
- acquiring a foreign object correction image from the initial image, wherein the foreign object correction image comprises foreign object information of the fingerprint entering region.
A texture detection device, comprising:
- a texture sensor, configured to collect a texture image;
- and
- an acquisition module, configured to perform an image difference calculation on a first texture image acquired by the texture sensor and a foreign object correction image acquired by the texture sensor to compensate foreign object information in the first texture image, and to acquire a second texture image.
