Title:

SYSTEMS AND METHODS FOR CHANGING OPERATION MODES OF THE OPTICAL FILTER OF AN IMAGING DEVICE

Document Type and Number:

WIPO Patent Application WO/2018/019206

Kind Code:

A1

Abstract:

A system includes a storage device storing a set of instructions and at least one processor in communication with the storage device. When executing the instructions, the at least one processor is configured to cause the system to obtain a first operation mode of the optical filter and determine a brightness value of visible light of ambient light. The at least one processor may also cause the system to obtain a brightness threshold related to the first operation mode, compare the brightness value of the visible light of the ambient light with the brightness threshold, and determine whether a switching condition is satisfied based on the comparison result. Upon the determination that the switching condition is satisfied, the at least one processor may further cause the system to switch the first operation mode of the optical filter to a second operation mode.
