An image information processing method, comprising: acquiring (S110, S120, S210, S220, S310, S320) a color gamut space of a target interface and a color gamut space of a screen; in response to that the color gamut space of the target interface is inconsistent with the color gamut space of the screen, detecting whether a color gamut space conversion condition is met; and in response to that the color gamut space conversion condition is met, acquiring a blank area in the target interface; and in response to that a color included in the blank area meets a specified color condition, converting the color gamut space of the screen to make it consistent with the color gamut space of the target interface, wherein the conversion of the color gamut space refers to converting from a display gamut standard to another display gamut standard; and the color gamut space conversion condition comprises one of: whether the resources of an electronic device of the screen allows the conversion of the color gamut space to be performed; the electronic device having started performing the conversion of the color gamut space; a saturation of the target interface is lower than a specified saturation value, and a color gamut space range of the target interface is smaller than a color gamut space range of a screen; a saturation of the target interface is greater than a specified saturation value, and a color gamut space range of the target interface is greater than a color gamut space range of a screen; and wherein the specified color condition comprises that: a proportion of a first area in the blank area is greater than a target extent, wherein a color displayed in the first area is chromatic colors while the first area is displayed. acquiring (S110, S120, S210, S220, S310, S320) a color gamut space of a target interface and a color gamut space of a screen; in response to that the color gamut space of the target interface is inconsistent with the color gamut space of the screen, detecting whether a color gamut space conversion condition is met; and in response to that the color gamut space conversion condition is met, acquiring a blank area in the target interface; and in response to that a color included in the blank area meets a specified color condition, converting the color gamut space of the screen to make it consistent with the color gamut space of the target interface, wherein the conversion of the color gamut space refers to converting from a display gamut standard to another display gamut standard; and the color gamut space conversion condition comprises one of: whether the resources of an electronic device of the screen allows the conversion of the color gamut space to be performed; the electronic device having started performing the conversion of the color gamut space; a saturation of the target interface is lower than a specified saturation value, and a color gamut space range of the target interface is smaller than a color gamut space range of a screen; a saturation of the target interface is greater than a specified saturation value, and a color gamut space range of the target interface is greater than a color gamut space range of a screen; and wherein the specified color condition comprises that: a proportion of a first area in the blank area is greater than a target extent, wherein a color displayed in the first area is chromatic colors while the first area is displayed. whether the resources of an electronic device of the screen allows the conversion of the color gamut space to be performed; the electronic device having started performing the conversion of the color gamut space; a saturation of the target interface is lower than a specified saturation value, and a color gamut space range of the target interface is smaller than a color gamut space range of a screen; a saturation of the target interface is greater than a specified saturation value, and a color gamut space range of the target interface is greater than a color gamut space range of a screen; and wherein the specified color condition comprises that: a proportion of a first area in the blank area is greater than a target extent, wherein a color displayed in the first area is chromatic colors while the first area is displayed.
