A method for adjusting and displaying an image, comprising: monitoring a distance between a user in front of a display screen and the display screen; when monitoring that the distance between the user and the display screen is less than a preset threshold, determining an adjusted size of an image on the display screen according to the distance; and displaying the image on the display screen according to the adjusted size; wherein determining the adjusted size of the image on the display screen according to the distance comprises: i) calculating an adjusted height of the image according to S=n ∗ H, S being the distance between the user and the display screen, H being the adjusted height of the image, and a range of n being [3.5,5]; and determining an adjusted width of the image according to a preset aspect ratio of the image and the adjusted height of the image; and wherein monitoring the distance between the user and the display screen comprises monitoring a wireless signal sent by the user, and determining the distance between the user and the display screen according to an intensity of the wireless signal; the method further comprising: acquiring, from at least one other apparatus in a space where the display screen is located, a distance between the apparatus and the user collected by the at least one other apparatus, the at least one other apparatus being fixedly located at different orientations in the space and determining the distance between the at least one other apparatus and the user through monitoring the intensity of the wireless signal sent by the user; and determining a relative orientation between the user and the display screen according to the distance between the user and the display screen and the distance between the user and the at least one other apparatus, the relative orientation comprising: center, center-left and center-right; and the displaying the image on the display screen according to the adjusted size comprises: displaying the image on a display area of the display screen corresponding to the relative orientation according to the adjusted size. monitoring a distance between a user in front of a display screen and the display screen; when monitoring that the distance between the user and the display screen is less than a preset threshold, determining an adjusted size of an image on the display screen according to the distance; and displaying the image on the display screen according to the adjusted size; wherein determining the adjusted size of the image on the display screen according to the distance comprises: i) calculating an adjusted height of the image according to S=n ∗ H, S being the distance between the user and the display screen, H being the adjusted height of the image, and a range of n being [3.5,5]; and i) calculating an adjusted height of the image according to S=n ∗ H, S being the distance between the user and the display screen, H being the adjusted height of the image, and a range of n being [3.5,5]; and determining an adjusted width of the image according to a preset aspect ratio of the image and the adjusted height of the image; and wherein monitoring the distance between the user and the display screen comprises monitoring a wireless signal sent by the user, and determining the distance between the user and the display screen according to an intensity of the wireless signal; the method further comprising: acquiring, from at least one other apparatus in a space where the display screen is located, a distance between the apparatus and the user collected by the at least one other apparatus, the at least one other apparatus being fixedly located at different orientations in the space and determining the distance between the at least one other apparatus and the user through monitoring the intensity of the wireless signal sent by the user; and determining a relative orientation between the user and the display screen according to the distance between the user and the display screen and the distance between the user and the at least one other apparatus, the relative orientation comprising: center, center-left and center-right; and acquiring, from at least one other apparatus in a space where the display screen is located, a distance between the apparatus and the user collected by the at least one other apparatus, the at least one other apparatus being fixedly located at different orientations in the space and determining the distance between the at least one other apparatus and the user through monitoring the intensity of the wireless signal sent by the user; and determining a relative orientation between the user and the display screen according to the distance between the user and the display screen and the distance between the user and the at least one other apparatus, the relative orientation comprising: center, center-left and center-right; and the displaying the image on the display screen according to the adjusted size comprises: displaying the image on a display area of the display screen corresponding to the relative orientation according to the adjusted size.
