Dual sensor imaging system and privacy protection imaging method thereof

A dual sensor imaging system and a privacy protection imaging method thereof are provided. The system is configured to control at least one color sensor and at least one IR sensor to respectively capture multiple color images and multiple IR images using multiple exposure conditions adapted for an imaging scene, adaptively select a combination of the color image and the IR image that can reveal details of the imaging scene, detect a feature area having features of a target of interest in the color image, and fuse the color image and IR image to generate a fused image having details of the imaging scene, crop an image of the feature area from the fused image and replace the cropped image with an image not belonging to the IR image, so as to generate a scene image.
