The application discloses a high dynamic range image processing system and method, electronic equipment and a readable storage medium. The high dynamic range image processing system includes an image sensor, a high dynamic range image processing module, an image processor and an image fusion module. The pixel array in the image sensor is exposed, at least one single-color photosensitive pixel is exposed at the first exposure time in the same subunit, at least one single-color photosensitive pixel is exposed at the second exposure time, and at least one full-color photosensitive pixel is exposed at the third exposure time . The high dynamic range image processing module performs high dynamic range image processing on the first color original image and the second color original image to obtain the first color high dynamic range image; the image processor performs high dynamic range image processing on the first color high dynamic range image and the first panchromatic original image The image is processed to obtain a second color high dynamic range image; the image fusion module fuses the first color high dynamic range image and the second color high dynamic range image to obtain a target image.
Description
technical field [0001] The present application relates to the technical field of image processing, in particular to a high dynamic range image processing system, a high dynamic range image processing method, electronic equipment, and a non-volatile computer-readable storage medium. Background technique [0002] Electronic devices such as mobile phones may be provided with a camera to realize a camera function. An image sensor for receiving light may be arranged in the camera. A filter array may be provided in the image sensor. In order to improve the quality of the image obtained, full-color photosensitive pixels are usually added to the filter array, so the parameters of the image processor need to be changed to process the image signal output by the image sensor, which increases the cost and design difficulty. Facilitate mass production of products. Contents of the invention [0003] Embodiments of the present application provide a high dynamic range image processing ...
