Embodiment Construction

[0027] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0028] Real world scenes often have a very high dynamic range in brightness. However, ordinary digital imaging devices (such as cameras) will convert the high-bit RAW image on the sensor during the imaging process (RAW image refers to the raw data that the CMOS or CCD image sensor converts the captured light source signal into a digital signal, usually a single Channel 16b or 12-bit...

Abstract

The invention is suitable for the technical field of image processing, and provides a dynamic image processing method and device, and the method comprises the steps of obtaining the pixel values of all pixels in a to-be-processed image; counting the number of pixel points of which the pixel values are in a preset interval; according to the number, adjusting pixel values of all pixel points in theto-be-processed image to obtain a first image and a second image; and fusing the to-be-processed image, the first image and the second image to obtain a target image. Through the scheme, the target image is formed by fusing different exposure images of the same image. Compared with the prior art, the image is formed by fusing different exposure images of the same image, so that the problems of ghosting, blurring or boundary traces and the like on the HDR image can be solved.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a dynamic image processing method, device, terminal equipment, and computer-readable storage medium. Background technique [0002] Dynamic range is used to describe the range of light intensity distribution in the picture from the darkest shadow part to the brightest highlight part. However, due to shooting in an environment with a large light ratio, the camera is limited by the dynamic range and cannot record extremely bright or dark details. Therefore, high-dynamic range imaging technology (High-Dynamic Range, HDR) was born. HDR technology takes three images with different exposures, and then fuses them to form an HDR image, so that the image has a larger dynamic range to improve the image quality. [0003] However, since the images of the three different exposures were not taken at the same time, problems such as ghosting, blurring or border ma...
