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

The invention discloses an HDR image generation method and device, a storage medium and image processing equipment, and the method comprises the steps: carrying out the photographing for multiple times, wherein the exposure parameters of pixels in a pixel array are different during photographing each time so that an image obtained through photographing contain the spatial domain dynamic information; and performing time domain dynamic processing on the images obtained through multiple times of photographing, so that a high-dynamic-range image can be obtained, wherein multiple exposure parameters are used in multiple times of photographing. Through the method, two dimensions of a time domain and a space domain can be combined, so that the dynamic range of the finally obtained HDR image is larger, more dynamic information is provided, and a better dynamic image effect can be obtained through subsequent image algorithm synthesis.

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...
