An electronic device photographing method, wherein the electronic device comprises a camera module, a display screen including a main display screen, and at least one flexible display screen, and the method comprises: in response to the electronic device enters a photographing scenario, determining target luminance of the display screen including the main display screen and the at least one flexible display screen, characterized in that the determining the target luminance step comprises: based on luminance of a photographing screen of an imaging chip of the camera module, determining the target luminance of the display screen by: dividing the main display screen of the electronic device into m*n child windows with m rows and n columns; determining a mapping relationship between each column of child windows of the main display screen and the display screen; determining, as luminance of fill-in light of each child window, a difference between display luminance of each child window after an image of a photographed object is formed on the main display screen and a preset threshold; determining, based on the mapping relationship between each column of child windows and the display screen and based on the determined luminance of fill-in light of each child window, the target luminance of the display screen to which each column of child windows are mapped; and in response to a determined target luminance and a detection that a photographing button of the electronic device is pressed, adjusting luminance of the display screen. in response to the electronic device enters a photographing scenario, determining target luminance of the display screen including the main display screen and the at least one flexible display screen, characterized in that the determining the target luminance step comprises: based on luminance of a photographing screen of an imaging chip of the camera module, determining the target luminance of the display screen by: dividing the main display screen of the electronic device into m*n child windows with m rows and n columns; determining a mapping relationship between each column of child windows of the main display screen and the display screen; determining, as luminance of fill-in light of each child window, a difference between display luminance of each child window after an image of a photographed object is formed on the main display screen and a preset threshold; determining, based on the mapping relationship between each column of child windows and the display screen and based on the determined luminance of fill-in light of each child window, the target luminance of the display screen to which each column of child windows are mapped; and dividing the main display screen of the electronic device into m*n child windows with m rows and n columns; determining a mapping relationship between each column of child windows of the main display screen and the display screen; determining, as luminance of fill-in light of each child window, a difference between display luminance of each child window after an image of a photographed object is formed on the main display screen and a preset threshold; determining, based on the mapping relationship between each column of child windows and the display screen and based on the determined luminance of fill-in light of each child window, the target luminance of the display screen to which each column of child windows are mapped; and in response to a determined target luminance and a detection that a photographing button of the electronic device is pressed, adjusting luminance of the display screen.
