摘要： An image capture device including an image capture module and a display panel is provided. The display panel is disposed on the image capture module and includes multiple pixels. Each of the pixels includes a first light-emitting region and a second light-emitting region. The first light-emitting region emits a first light beam. The first light beam is transmitted to the image capture module through a region outside the first light-emitting region. In each of the pixels, a total area of the first light-emitting region is smaller than a total area of the second light-emitting region.

摘要： A fingerprint sensing device includes a fingerprint sensor and a processor. The fingerprint sensor is configured to acquire a plurality of fingerprint reference frames. The processor is coupled to the fingerprint sensor. The processor is configured to superimpose the plurality of fingerprint reference frames. The processor analyzes the plurality of fingerprint reference frames to determine multiple first regions and multiple second regions of the plurality of fingerprint reference frames. The processor calculates multiple reference pixel values of the plurality of fingerprint reference frames according to multiple weight value functions to generate a superimposed fingerprint frame. The weight value functions corresponding to the first regions of the plurality of fingerprint reference frames are linearly changed.
