Digital camera imaging method to realize high-definition display of high dynamic range images

Abstract

The invention relates to a digital camera imaging method for realizing high-definition display of high dynamic range images. The multi-channel vertical optical spectroscopic method is used to make the natural light pass through the main lens of the digital camera to form the main channel transmitted light, and the main channel transmitted light is divided into multiple Lu Guang, set the optimal exposure time, obtain multiple frames of original images with different exposure times for the same scene and process the original images of each frame in parallel; pre-set the camera response curve, and establish the search between the brightness of each frame of the original image and the corresponding exposure time Table, the camera response curve is finally obtained; the original image of each frame is corrected and processed by the color correction processing method; the image fusion method is set to fuse the original images of each frame by using the calibrated camera response curve, and the original image of each frame is denoised by the hybrid filter. Use tone mapping and use 16 bits to represent each pixel in each frame of the original image, so as to accurately display the fused high dynamic range image.

Description

technical field [0001] The invention relates to the technical field of high-definition and high-precision microscopic imaging detection, in particular to a digital camera imaging method for realizing high-definition display of high-dynamic-range images. Background technique [0002] Digital images have become an indispensable part of people's life and social and economic activities. With the continuous improvement of people's requirements for digital image quality, digital imaging technology is also improving, and digital imaging quality shows the development trend of high resolution, high speed, low noise and high dynamic range. [0003] Although the existing digital photography technology is very advanced in terms of signal acquisition and display methods, there are still major technical deficiencies in the products on the domestic and international markets that cause blurred images due to insufficient dynamic range of video signal acquisition. For many important scenes e...

Problems solved by technology

Existing digital cameras and image and video standards use 8 bits (0-255) to represent the gray value of each pixel, which obviously can only represent a small part of the color range in the real world, which is why existing technologies and products cannot The root cause of fully illuminating this high dynamic scene
