A scene-based image processing method includes: performing decoding after acquiring video data to obtain multiple image frames, and identifying key frame images by performing key frame detection (S10); analyzing similarity between the content of two adjacent key frame images, and determining whether the difference in the content of the two adjacent key frame images is within a preset threshold (S20); and when the difference in the content of the two adjacent key frame images is within the preset threshold, determining that the two adjacent key frame images are a same scene, uniformly performing image feature statistics compilation, overlaying feature information, and performing image enhancement on a same scene by using a similar enhancement processing curve (S30).
