More Information
Summary:The present invention provides an imaging system, comprising: a lens, an image sensor, and a dual-mode optical filter. The lens is utilized for receiving a visible light and an IR light. The image sensor comprises: a pixel array, a micro-lens array, and an IR filter array. The pixel array has a first group of pixels and a second group of pixels. The IR filter array comprises a group of IR blocking filters for blocking the IR light to prevent the IR light from reaching the second group of pixels. The dual-mode optical filter is disposed between the lens and the image sensor, and has a dual window transmission spectrum comprising: a first pass band to pass the IR light; and a second pass band to pass the visible light both onto the image sensor.
