[0080] see figure 2 As shown, it is a schematic flowchart of an image synthesis method in an embodiment. The image synthesis method in this embodiment comprises the following steps:

[0081] Step S110: Obtaining a first exposure image and a second exposure image of the target subject respectively, wherein the exposure time of the first exposure image is greater than the exposure time of the second exposure image;

[0082] In this step, the first exposure image and the second exposure image are obtained after shooting the same target subject, and the exposure time of the two is different. In order to capture more image details, the first exposure image and the second exposure The exposure time difference of the image can be greater than the preset time span;

[0083] Step S120: Acquiring the weight value of image fusion according to the pixel point data at the same position of the first exposure image and the second exposure image;

[0084] In this step, the size of the fir...

Abstract

The invention relates to a method, a system and a device for synthesizing an image, belonging to the technical field of image processing. The method comprises the steps of: acquiring exposed images oftwo different exposure times of a target photographic subject, analyzing pixel point data of the same position in the two exposed images to obtain an image fused weight value, and fusing the two exposed images by using the weight value to obtain a composite image, wherein the composite image is synthesized by images of different exposure times, and the pixels at the same position are capable of capturing more image details, thereby improving the dynamic range of the composite image. At the same time, only two images with different exposure times are needed in the process of synthesizing the images, the amount of image calculation is reduced compared with the traditional technology, by which the synthesis process uses multiple images, which can meet the real-time requirements of image processing.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image synthesis method, system and equipment. Background technique [0002] With the progress of electronic technology, image imaging systems are more and more integrated into many portable electronic products, such as mobile phones, driving recorders and other products. Taking photos and videos are their main functions, and at the same time, the quality requirements for imaging images are also very high. Higher and higher, the dynamic range of the image is one of the main indicators of the imaging system. [0003] Generally, the dynamic range of CMOS camera imaging is relatively narrow, and it is impossible to capture images in the full dynamic range from dark to starlight to bright to sunlight. Therefore, increasing the dynamic range of imaging images can capture more image details. For products such as driving recorders and automatic driving systems, it ca...
