A method for displaying a picture comprising: acquiring a current posture information of a terminal; selecting a target area in a first preset picture as a current wallpaper picture of the terminal according to the posture information; and displaying the wallpaper picture in a screen display area of the terminal, said method characterized in that • said current posture information comprises an Euler angle information α, β, γ in a 3-dimensional coordinate system of originate O and having the same directions as a coordinate system of a sensor in the terminal wherein α, β, γ correspond to a right and left tilt angle, a back and forth tilt angle and a right and left swing angle; • the step of selecting the target area in said first preset picture as the current wallpaper picture of the terminal according to the posture information comprises: ∘ determining a virtual screen area of the terminal as a plane area of length a and of width b according to the posture information, said virtual screen area being perpendicular to OE, wherein E is a center point of said plane area defined by coordinates α+π/2, β-π/2, r where r is the length of OE and wherein said right and left swing angle of said plane area is γ; ∘ projecting the virtual screen area of the terminal to a spherical picture from said originate O, said spherical picture being obtained by curling said first preset picture into a sphere; ∘ determining a target area projected by the virtual screen area of the terminal in said spherical picture; and ∘ determining a target area in said first preset picture according to the target area in said spherical picture, and selecting the target area in said first preset picture as the current wallpaper picture of the terminal. acquiring a current posture information of a terminal;
