Disclosed in embodiments of the present invention are a method and a device for video signal processing, relating to the technical field of terminals. Disclosed is a method for video signal processing, comprising: acquiring an electrical signal indicating ambient light brightness; determining a brightness adjustment value on the basis of the electrical signal; performing, on the basis of the brightness adjustment value, color space conversion on a received video signal; outputting the converted video signal. Also disclosed in embodiments of the present invention are a device and a system corresponding to the video signal processing method. Embodiments of the present invention enable a video playback device, when in conditions of comparative darkness, to automatically adjust the brightness of a video screen according to the ambient brightness, thus lowering the contrast between the video screen and the surroundings, thereby reducing damage to eyes. |
