Document Type and Number:
WIPO Patent Application WO/2021/208593
Kind Code:
A1
Abstract:
A high dynamic range image processing system (100) and method, an electronic device (1000), and a computer-readable storage medium (400). The high dynamic range image processing system (100) comprises an image sensor (10), a high dynamic fusion unit (50), and an image processor (20). A pixel array (11) is exposed at a first exposure time to obtain a first original image, and is exposed at a second exposure time to obtain a second original image. The image processor (20) and the high dynamic fusion unit (50) are used for performing image preprocessing, high dynamic range processing, image processing, and fusion algorithm processing on the first original image and the second original image to obtain a target image.
