Problems solved by technology

In the existing technology, the brightness alignment of multiple images is based on the brightness compensation based on the exposure parameters. This method will cause errors in the alignment of the image brightness when the exposure parameters are inaccurate, such as image alignment problems and excessive image brightness. Unnatural boundaries Wait

Abstract

The present application discloses an image processing method, device, storage medium, and electronic equipment. The method includes: acquiring multiple frames of original images with different exposures, selecting a reference frame from among the multiple frames of original images, and dividing the original image according to the brightness of the original image The original image is divided into multiple pixel sets, and the gain coefficient between the original image to be processed and the reference frame other than the reference frame is calculated according to the pixel set, and the brightness compensation of the original image to be processed is performed through the gain coefficient. The application can perform brightness alignment on multi-frame images without depending on exposure parameters, avoid image brightness misalignment caused by incorrect exposure parameters, and improve the accuracy of brightness alignment on multi-frame images.

Description

technical field [0001] The present application belongs to the technical field of artificial intelligence, and in particular relates to an image processing method, device, storage medium and electronic equipment. Background technique [0002] With the development of electronic technology, high dynamic range (High Dynamic Range, HDR) imaging technology has gradually become popular among electronic devices with camera functions such as smart phones and digital cameras. Compared with ordinary images, it can provide more dynamic range. And image details, according to LDR (Low-Dynamic Range) images with different exposure times, use the LDR images corresponding to the best details for each exposure time to synthesize the final HDR image. [0003] At present, the high dynamic range images generated on most devices are synthesized from multiple images with different exposures. Due to camera shake and moving objects, spatial alignment of the camera and moving objects is required. Ho...
