Problems solved by technology

Some high dynamic cameras with high dynamic range function use pixel arrays with higher sensitivity, and at the same time increase the shutter speed to reduce the exposure to save more details of the highlight part; The speed at which the photosensitive pixels reach light saturation slows down, which puts higher requirements on the hardware parameters of the image sensor of the high dynamic camera, which increases the cost and makes the design more difficult, which is not conducive to the mass production of products

Abstract

The invention discloses an image sensor, a high dynamic range image processing system and method, electronic equipment and a computer readable storage medium. The high dynamic range image processing system comprises an image sensor, a color high dynamic fusion unit and an image processor. When the pixel array in the image sensor is exposed, at least one single-color photosensitive pixel in the same subunit is exposed at a first exposure time; wherein the at least one single-color photosensitive pixel is exposed at a second exposure time less than the first exposure time, the at least one full-color photosensitive pixel is exposed at a third exposure time less than or equal to the first exposure time, and the at least one full-color photosensitive pixel is exposed at a fourth exposure timeless than the first exposure time. And the color high-dynamic fusion unit and the image processor are used for performing high-dynamic range processing, image processing and fusion algorithm processing on the first color original image, the second color original image and the panchromatic original image to obtain a target image.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image sensor, a high dynamic range image processing system and method, electronic equipment, and a computer-readable storage medium. Background technique [0002] Ordinary cameras cannot record extremely bright or dark details due to the limited dynamic range. Especially when the light in the shooting scene is relatively large, it is easy to overexpose or underexpose. A camera with a high-dynamic range (High-Dynamic Range, HDR) function can capture images under a large light ratio, and can perform better than ordinary cameras in both high light and dark positions. Some high dynamic cameras with high dynamic range function use pixel arrays with higher sensitivity, and at the same time increase the shutter speed to reduce the exposure to save more details of the highlights; or select the photosensitive pixels with a logarithmic response curve, resulting ...
