Image enhancement method and image enhancement device

The invention discloses an image enhancement method and an image enhancement device in the field of computer vision in the field of artificial intelligence, and the method comprises the steps: obtaining a first HDR image corresponding to a to-be-processed image and color image features of the to-be-processed image, the to-be-processed image being an image of a first resolution, the first HDR image is an image of a second resolution, the first resolution is greater than the second resolution, and the color image features are used for indicating different brightness areas or different color change areas in the to-be-processed image; inputting the first HDR image into a neural network model for super-resolution processing; and performing image enhancement processing on the first HDR image after super-resolution processing and the color image features through a neural network model to obtain a second HDR image corresponding to the to-be-processed image, the second HDR image being an HDR image of which the resolution is the first resolution. According to the technical scheme, the image enhancement processing effect can be improved.
