METHOD AND DEVICE FOR CONTROLLING LIGHT EMISSION SCREEN Russian patent published in 2019 - IPC H01J61/00 H04N5/225 G03B15/03 

FIELD: control systems.

SUBSTANCE: invention relates to the field of display technologies and, in particular, to the light emission screen control method and device. Method includes: detecting whether the flash lamp function of the screen is in the "on" state when in the photographing mode, wherein the flash lamp function of the screen means a function in which the screen serves as a flash lamp; and controlling the light emitting screen in accordance with the first color temperature correction circuit, when it is required that the screen serves as a flash lamp for emitting light, if the flash lamp function of the screen is in the "on" state, wherein first color temperature correction circuit is set in accordance with initial color temperature and target color temperature of screen, wherein initial color temperature of screen means color temperature, at which screen emits light in case color shift correction is not performed. Due to preliminary setting of the color temperature correction circuit in the terminal device, when it is required that the screen of the terminal device serves as a flash lamp for light emitting, the screen is controlled for light emission in accordance with the color temperature correction circuit so that the color of the photographed in the end object matched user expectations.

EFFECT: high quality of photography.
