Embodiment Construction

[0030] As mentioned in the background art, the dynamic range of the generated HDR image in the prior art is low, especially when tracking and shooting a moving target, the effect of the obtained HDR image is poor, such as ghosting, ghosting and other phenomena.

[0031] In order to solve the above problems, an embodiment of the present invention provides a method and device for generating an HDR image, a storage medium, and an image processing device. The method for generating an HDR image includes: taking multiple shots, and the number of pixels in the pixel array for each shot The exposure parameters are different, so that the images obtained by each shooting contain dynamic information in the spatial domain; the images obtained by multiple shootings are processed in the time domain to obtain high dynamic range images, wherein the multiple shootings use multiple exposures parameter.

[0032] Through the method for generating the HDR image, the dynamic range of the HDR image ...

Abstract

A method and device for generating an HDR image, a storage medium, and an image processing device, wherein the method includes: performing multiple shots, and the exposure parameters of pixels in a pixel array are different for each shot, so that the obtained images obtained by each shot are different. The image contains dynamic information in the spatial domain; the images obtained by multiple shootings are subjected to dynamic processing in the time domain to obtain a high dynamic range image, wherein the multiple shootings use multiple exposure parameters. Through this method, the two dimensions of the temporal domain and the spatial domain can be combined, so that the finally obtained HDR image has a larger dynamic range and more dynamic information, which is beneficial to the subsequent image algorithm synthesis to obtain a better dynamic image effect.

Description

technical field [0001] The present invention relates to the field of image processing, and in particular to a method and device for generating an HDR image, a storage medium, and an image processing device. Background technique [0002] High-Dynamic Range (HDR) images can provide more dynamic range and image details than ordinary images, and are closer to images seen by human eyes. The general implementation method of the existing HDR technology is: turn on the camera and switch to the HDR mode, click to take a picture, and continuously acquire multiple frames of image data with different exposure values ​​(Exposure Value, EV for short), and synthesize the HDR image according to the set synthesis algorithm . [0003] However, the dynamic range of the HDR image obtained by the existing HDR image generation method is still not enough to simulate the image seen by the human eye, especially when tracking and shooting a moving target, the effect of the captured HDR image is poor...
