Abstract: An image acquisition device and a fingerprint acquisition apparatus. The image acquisition device includes a transparent plate, an image sensor disposed under the transparent plate, and a light blocking layer disposed on an upper surface of the transparent plate. The light blocking layer is provided with a plurality of light transmission pinholes, and an image-side angle of view of the light transmission pinhole is ?=arcsin(n1/n2), where n2>n1. A distance d between centers of adjacent light transmission pinholes is greater than or equal to a diameter Dimage of an image-side field of view of the light transmission pinhole. The image acquisition device confines the size of the image-side field of view of the light transmission pinhole by using transparent mediums with different refractive indexes.

Abstract: The present application discloses a method for controlling fingerprint acquisition based on a display screen and a related apparatus, which are applied to a display screen with a fingerprint acquisition function. In the disclosure, by detecting a fingerprint acquisition triggering instruction generated in an electronic device in real time, a preset fingerprint acquisition region of the display screen is controlled to emit light and a fingerprint sensor is triggered to acquire a fingerprint image, if and only if the fingerprint acquisition triggering instruction is detected. When the fingerprint acquisition triggering instruction does not exist, the display screen is not affected and the fingerprint sensor is in a non-operating state so as to save energy.
