A method for controlling at least two flash lights, wherein a first and second flash light are located in the same plane, the method comprising: detecting position data of an object to be photographed, wherein the position data includes a distance between the object to be photographed and the flash lights; and determining a parameter of each of the flash lights with respect to the object to be photographed based on the position data; determining a parameter of the flash light with respect to the object to be photographed based on the position data, comprises: determining a first current or voltage to be provided to the first flash light and a second current or voltage to be provided to the second flash light based on the position data; and determining a light intensity of the flash light with respect to the object to be photographed based on the current or voltage; characterised in that the method further comprises: determining a light emitting angle (θ 1, θ 2) of the first and second flash lights based on the light intensity, the light emitting angles being implemented by a first lens for the first flash light and a second lens for the second flash light, wherein: the flash light that provides a smaller light intensity has a larger light emitting angle, whereby the intensity of the light transmitted from the center of the lens of that flash light is smaller than the intensity of the light transmitted from the periphery of the first lens; and the flash light that provides a larger intensity has a smaller light emitting angle, whereby the intensity of the light transmitted from the center of the lens of that flash light is larger than the intensity of the light transmitted from the periphery of the second lens. detecting position data of an object to be photographed, wherein the position data includes a distance between the object to be photographed and the flash lights; and determining a parameter of each of the flash lights with respect to the object to be photographed based on the position data; determining a parameter of the flash light with respect to the object to be photographed based on the position data, comprises: determining a first current or voltage to be provided to the first flash light and a second current or voltage to be provided to the second flash light based on the position data; and determining a light intensity of the flash light with respect to the object to be photographed based on the current or voltage; determining a first current or voltage to be provided to the first flash light and a second current or voltage to be provided to the second flash light based on the position data; and determining a light intensity of the flash light with respect to the object to be photographed based on the current or voltage; characterised in that the method further comprises: determining a light emitting angle (θ 1, θ 2) of the first and second flash lights based on the light intensity, the light emitting angles being implemented by a first lens for the first flash light and a second lens for the second flash light, wherein: the flash light that provides a smaller light intensity has a larger light emitting angle, whereby the intensity of the light transmitted from the center of the lens of that flash light is smaller than the intensity of the light transmitted from the periphery of the first lens; and the flash light that provides a larger intensity has a smaller light emitting angle, whereby the intensity of the light transmitted from the center of the lens of that flash light is larger than the intensity of the light transmitted from the periphery of the second lens. the flash light that provides a smaller light intensity has a larger light emitting angle, whereby the intensity of the light transmitted from the center of the lens of that flash light is smaller than the intensity of the light transmitted from the periphery of the first lens; and the flash light that provides a larger intensity has a smaller light emitting angle, whereby the intensity of the light transmitted from the center of the lens of that flash light is larger than the intensity of the light transmitted from the periphery of the second lens.
