Dual sensor imaging system and imaging method thereof

A dual sensor imaging system and an imaging method thereof are provided. The dual sensor imaging system includes at least one color sensor, at least one infrared ray (IR) sensor, a storage device and a processor. The processor is configured to load and execute a computer program stored in the storage device to: identify an imaging scene of the dual sensor imaging system; control the color sensor and the IR sensor to respectively capture multiple color images and multiple IR images, respectively, using multiple exposure conditions under the imaging scene; adaptively selecting a combination of the color image and the IR image that can reveal details of the imaging scene; and fuse the selected color image and IR image to generate a scene image having details of the imaging scene.
