Abstract: An optical fingerprint sensor configured to be arranged under an at least partially transparent display panel comprises an array of color controllable light sources. The optical fingerprint sensor comprises an image sensor comprising a photodetector pixel array; an array of microlenses arranged under the color controllable light sources; a color filter layer arranged under the array of microlenses comprising alternating filter element types of different colors for adjacent subsets of pixels in the photodetector pixel array. The color controllable light sources are controllable, in response to a first finger condition, to emit light of uniform color being a mix of the colors of the filter elements, and in response to a second finger condition, to emit a color pattern including the colors of the filter elements, wherein groups of color controllable light sources are controlled to emit light corresponding to a color of the filter elements.

Abstract: An iris recognition system and method configured to reduce impact of impairment data in captured iris images. The system comprises a camera configured to capture first and second images of a user's iris. A processing unit of the system is configured to cause the user to change gaze between the capturing of the first and second images, create a representation of each of the first and second iris images, where each spatial sample of an image sensor of the camera capturing the iris images is gaze-motion compensated to correspond to a same position on the iris for the sequentially captured first and second iris images, thereby causing the iris to be fixed in the representations while any impairment data will move with the change in gaze of the user, and to filter the moving impairment data from at least one of the representations of the first and second iris images.
