Embodiment 1
[0041] Please refer to figure 1 as shown, figure 1 A method for image wide dynamic enhancement of the present invention is shown, comprising the following steps:
[0042] Step S1: Acquire a template image; wherein, the scene of the template image and the scene of the image to be optimized are the same scene, and the dynamic range of the template image satisfies the preset dynamic range, and the exposure value of each pixel in the template image All meet the preset exposure range;
[0043] In this embodiment, the template image may be a pre-stored optimized image, or an image whose dynamic range and exposure value meet the preset dynamic range and preset exposure range, respectively, obtained directly through the network.
[0044] In this embodiment, a scene refers to certain conditions for image generation, and certain conditions include but are not limited to conditions such as environment, location, and space. The same scene may refer to the same environment, location and...
Embodiment 2
[0074] Please refer to figure 2 as shown, figure 2 A wide dynamic image enhancement device of the present invention is shown, including:
[0075] The template image acquiring module 10 is used to acquire the template image; wherein, the scene of the template image is the same scene as the scene of the image to be optimized, and the dynamic range of the template image satisfies the preset dynamic range, each of the template images The exposure values of the pixels all meet the preset exposure range;
[0076] The optimization module 20 is configured to filter and optimize the pixel values of each pixel of the image to be optimized through a convolution kernel according to the pixel values of each pixel in the template image, to obtain filtered and optimized pixel values of each pixel.
[0077] Carry out specific embodiment description below:
[0078] Taking a single-channel image as an example, first obtain an image with a relatively wide dynamic range in the same s...
