The present disclosure relates to a speckles detection system for detecting one or more speckles on a surface of an optical element of an image capturing device. The system comprises: one or more light sources configured to emit a light beam towards the optical element, the optical element being configured to reflect light from the light sources when speckles are located on the surface of the optical element. The system further comprises one or more light receivers configured to receive the light beam reflected by the optical elements such that speckles on the surface of the optical elements are detected. Methods for detecting one or more speckles on a surface of an optical element of an image capturing device are also provided.

In some aspects, the present disclosure provides a method for managing a command queue in a universal flash storage (UFS) host device. The method includes determining to power on a first subsystem of a system-on-a-chip (SoC), wherein the determination to power on the first subsystem is made by a second subsystem of the SoC based on detection of user identity data contained in a first image frame during an initial biometric detection process. In certain aspects, the second subsystem is configured to operate independent of the first subsystem and control power to the first subsystem. In certain aspects, the second subsystem includes a second optical sensor, a set of ambient sensors, and a second processor configured to detect, via a set of ambient sensors, an event comprising one or more of an environmental event outside of the device or a motion event of the device.

An image processing method includes acquiring an image obtained by imaging of an object, ambient light data during the imaging, and reflection characteristic data and transmission characteristic data which depend on a concentration of a material contained in the object, and separating a reflected light component and a transmitting light component in the image using the ambient light data, the reflection characteristic data, and the transmission characteristic data.
