Abstract
An electronic device includes at least one grid structure that extends in rows and columns of a pixel array including a plurality of imaging pixels and is structured to separate the imaging pixels from one another to provide optical isolation between two adjacent imaging pixels, a grid shutter coupled to the grid structure and configured to allow a gas to enter the grid structure by opening a passage for the gas or block the gas from entering the grid structure by closing the passage in the grid structure, and a gas detection controller configured to identify the gas flowing into the grid structure based on an image that is acquired by the image sensor when the passage for the gas in the grid structure is opened to allow the gas to be present in the grid structure.
