Signal lamp color enhancement method and device and electronic equipment

The embodiment of the invention provides a signal lamp color enhancement method and device and electronic equipment, and relates to the technical field of images. The signal lamp color enhancement method comprises the following steps: acquiring a first proportion, wherein the first proportion comprises a proportion between a first to-be-enhanced region and a first region of interest recognized from the sample image by using a preset model; dividing a second region to be enhanced from a second region of interest of the live image by using a brightness threshold corresponding to the live image to obtain a second proportion between the second region to be enhanced and the second region of interest; determining an optimal brightness threshold value according to the first proportion and the second proportion; and performing color adjustment on a target enhancement region obtained from the second region of interest based on the optimal brightness threshold. Therefore, the position and the range of the bulb area in
